SACRAMENTO (AP) — California Gov. Jerry Brown plans to convene a climate conference next year, his latest action to position the state as a leader in battling global warming as the White House recedes.

The summit set for 2018 in San Francisco will mark the first time a state is hosting a climate gathering aimed at upholding the goals of the Paris climate agreement, an international pact to fight global warming that President Donald Trump is exiting.

Brown announced the Global Climate Action summit on Thursday in a video message to the Global Citizen Festival in Hamburg, Germany. His announcement comes as Trump is in Hamburg for a meeting of the Group of 20 economic powers, which includes many European allies that encouraged the president not to withdraw from the Paris agreement.

The Trump administration’s decision to roll back environmental regulations in the United States and withdraw from the international agreement has elevated Brown’s profile on the world stage. He traveled to China earlier this year to discuss climate policy and will serve as a special envoy to states and regions at the United Nation’s November climate conference.

“Yes, I know President Trump is trying to get out of the Paris agreement, but he doesn’t speak for the rest of America,” Brown said in the video. “We in California and in states all across America believe it’s time to act.”

Brown’s climate conference will feature representatives of subnational governments, businesses, investors, musicians and others to highlight action to fight global warming and to “spur deeper commitment” from national governments. A full list of attendees hasn’t been released, and it’s unclear if any foreign presidents or prime ministers plan to attend.

“It’s up to you and it’s up to me and tens of millions of other people to get it together to roll back the forces of carbonization and join together to combat the existential threat of climate change,” Brown said in the video.

Building alliances to fight climate change has been a key piece of Brown’s tenure. He’s already launched a multi-state effort to keep the country on track to meet the Paris goals and created an alliance of subnational governments aimed at slowing the warming of the planet.

Meanwhile in Sacramento, Brown is struggling to reach consensus on a bill to reauthorize California’s cap-and-trade program, the cornerstone of the state’s efforts to reduce carbon emissions.

Like the $6.5 billion in estimated U.S. health care costs from worsening air pollution that we are all paying for through higher insurance premiums and higher taxes.

If you have not made the connection between the current Washington, D.C., battles over health care on the one hand and the Paris Agreement on the other, you’re not alone. Though they are inextricably linked, the connection is often overlooked. The biggest impact of climate change will be on our health. Think of climate change as one big pre-existing condition that we will all have.

Most Americans understand that climate change poses a threat, but that threat appears decades off, with unclear consequences. Yet climate change is already affecting our health and the health of our children. Unless we heed these early warning signs, we will endure even greater health impacts.

This is why this week's G20 meeting of world leaders from major developed and developing economies, including the U.S., must mark a turning point where they agree not just to defend the Paris Agreement, but to implement it. We need to return to the business of tackling climate change and move towards solutions.

Governments are together spending billions of dollars a year to promote the production of fossil fuels — oil, gas and coal — that actively contribute to air pollution, premature deaths and climate damage that are already having major impacts on our health. G20 nations should work to phase out fossil fuel subsidies urgently. Additional revenue from the elimination of these subsidies will help governments, in rich and poor nations alike, fund programs that benefit health. In 2013 alone, air pollution from burning fossil fuels cost the United States economy billions of dollars in labor output losses (because people couldn’t work productively or work at all) and even more in health care costs.

The National Climate Assessment — an interagency initiative of the United States government — has concluded that the intensity, frequency and duration of North Atlantic hurricanes have increased substantially since the early 1980s, a trend that will continue as the climate continues to warm. With more extreme storms and flooding — events like Hurricane Katrina and Hurricane Sandy — our healthcare system is going to have to make expensive preparations. After Hurricane Sandy, several hospitals were closed for more than a month.

Perhaps most ominously, Americans and people across the globe are also at growing risk of exposure to infectious disease outbreaks. Last year’s Zika outbreak vividly demonstrated how previously overlooked diseases can spread quickly and unpredictably as the geographic range of disease vectors such as mosquitos and ticks changes. Recent outbreaks of other diseases such as Ebola remind us of the risk of a pandemic on the scale of the 1918 Spanish Influenza outbreak, whose centennial we will mark next year. That outbreak killed around 50 million people worldwide , including 675,000 Americans . Although it is not possible to know with certainty when or what the next outbreak will be, we would be foolish to ignore climate change’s contribution to this deadly threat.

It took U.S. leadership to forge the Paris Agreement, and ongoing U.S. leadership was critical to sustain that global agreement and make the world a healthier place not just for our kids and grandkids but even for us. We commend the leadership of governors and mayors and academic leaders across the nation who are making clear that while President Trump is abandoning the Paris Accord, America is not.

G20 countries need to be the champions of climate action, to take the lead from the thousands of cities, regions, businesses and investors who have come forward with increased ambition and continue to show their support for the Paris Agreement. We can learn from civil society who came together recently to present their vision of "the world we want" to the G20, bringing together more than 200 NGOs from over 60 countries. We can also learn from the industry-led initiative on climate-risk disclosure — which has been well-received by investors, asset managers and the like all over the world — encouraging companies to become transparent about climate change risk on their bottom line. When the science is strong that climate change will have devastating effects on our health, collective action and ambitious leadership are the only ways forward.

We stand with them, believing it has never been more urgent to ensure that Americans understand and prepare for the health risks we all face from climate change. Prevention is the best medicine, and acting now to mitigate these risks by remaining in the Paris Agreement is both morally imperative and fiscally sound. Climate change is one pre-existing condition we know how to cure.</s>India said today that it remains committed on the issue of climate change “as per its own values and requirements”, days after the US announced its decision to pull out of the landmark Paris agreement. External Affairs Ministry spokesperson Gopal Baglay said that the focus of the Indian government is on International Solar Alliance (ISA) and other methods of renewable energy. Arvind Panagariya, sherpa for India at the G20 Summit, said at the same media briefing that India would need “more time” to process completely to clean fuel. He said that the US position on climate change “remained different” from that of other countries as it wants inclusion of fossil fuel.

“Our stand has been very very clear that what we are committed on climate change as per our own values and more importantly in terms of our own requirements,” Baglay said when asked abut the key takeaway for India on climate change at the Summit. Baglay said solar energy and other renewables are the areas that have been in focus of Prime minister Narendra Modi’s conversation with other global leaders at the Summit. Panagariya said that India would need “more time” to process completely to clean fuel.

Speaking on the issue of the US’ stance on climate change, he said that “there were differences but nobody was isolated, though Europeans had much stronger position”. “India’s position remains that we need more time to process completely to clean fuel. US position on climate change remains different from that of other countries and it wants inclusion of fossil fuel,” Panagariya said. Prime Minister Modi, while speaking at the meeting of BRICS leaders, on the sidelines of the G20 Summit yesterday had said that it was “mandatory” to implement the consensus of the Paris agreement on climate change. He had asserted that India will implement the accord in “letter and spirit”.

President Donald Trump had recently announced that the US will withdraw from the Paris climate accord, saying the deal agreed by more than 190 nations unfairly benefited countries like India and China. The objective of the Paris Agreement is to prevent an increase in global average temperature and keep it well below 2°C. The Agreement was adopted on December 12, 2015, by 195 parties to the United Nations Framework Convention on Climate Change (UNFCCC), replacing its predecessor Kyoto Protocol. It was finally ratified on November 4, 2016.</s>Theresa May said she was dismayed about Donald Trump's decision to pull out of the international agreement to tackle climate change as the US president was left isolated on the issue at the G20 summit.

The Prime Minister said she urged Mr Trump to rejoin the Paris climate change agreement and raised it with him on the sidelines of the gathering in Hamburg, although it was not one of the items on the agenda in the formal meeting between the two leaders.

She said: "Like other world leaders here, I am dismayed at the US decision to pull out of the Paris agreement and I have urged President Trump to rejoin the Paris agreement.

"The UK's own commitment to the Paris agreement and tackling global climate change is as strong as ever."

Challenged on why she had not used her bilateral meeting with the US president to tackle him on the issue, she said: "I did bring the issue of the climate change agreement up with President Trump, I've had a number of conversations with him over the time I have been here at the G20.

"When I brought it up with him, what I did was I encouraged him to bring the United States back into the Paris agreement.</s>“This is a clear indication that the U.S. has isolated itself on climate change once again, and is falling back while all other major economies step up and compete in the clean energy marketplace created by the Paris Agreement estimated to be worth over 20 trillion dollars,” said Andrew Light, a senior climate change adviser at the State Department under Mr. Obama.

Differences between the United States and other nations on climate, trade and migration made for a tricky summit meeting, which unfolded amid large protests that sometimes turned violent, with several injured and demonstrators setting fire to cars and looting in the streets of the German city.

“Nothing’s easy,” Mr. Trump said of the gathering on Saturday as he complimented its host, Chancellor Angela Merkel of Germany, who has toiled to bridge the gap between the United States and other nations, for handling the challenge “so professionally.”

Hours later, at the start of a high-stakes meeting with President Xi Jinping of China, Mr. Trump vowed to confront the threat posed by North Korea “one way or the other,” and said he appreciated the Chinese leader’s efforts to respond to Pyongyang’s latest provocations.

“It may take longer than I’d like, it may take longer that you’d like, but there will be success in the end, one way or the other,” Mr. Trump said.

The wording on climate change in the communiqué represented a much-needed victory for Ms. Merkel, who played a major role in forging compromise language after France raised objections.

In most other respects, though, the summit meeting had to be a bitter disappointment for the chancellor. When the meeting was first planned for Hamburg, Ms. Merkel’s birthplace, she would have reasonably expected Hillary Clinton to be the American president, and she had expected the event to be a strong part of her re-election campaign for a fourth term, with voting in September.

But Mr. Trump tends to suck all the media air out of a room, even in Germany, where he is deeply unpopular. This summit meeting was always going to be primarily about Mr. Trump and his first meeting with President Vladimir V. Putin of Russia.

It has also been about efforts by most of the rest of the world to cajole the American president into softening his stances on global trade and the climate, with Ms. Merkel in a secondary role, trying to come up with compromises.

Her standing has also suffered as Germans have been shocked by violent protests by a small bloc of anarchists who saw the G-20 as a perfect platform for their rejection of capitalism and order.

The atmosphere around Hamburg has been that of an armed camp, hardly welcoming, with 20,000 police officers asking for further reinforcements to try to protect the various leaders here. So far, 213 police officers have been injured, and 43 people have been arrested and 96 more detained.

The central city has been shut down. There is no taxi or bus service, trams are often blocked by protesters and the subway is overcrowded. The area around the conference center is ringed by riot police officers while helicopters fly overhead and police sirens scream around various motorcades.

Some shops were looted and cars were burned, and the smell of burning tires wafted over the conference center. Even Melania Trump could not leave her guesthouse on Friday to join a spousal tour of the harbor.

Ms. Merkel expressly backed the 100,000 or so peaceful demonstrators who massed here in recent days and were marching on Saturday. She may have been hoping to show authoritarian leaders like Mr. Putin and Turkey’s president, Recep Tayyip Erdogan, how to tolerate protests in a democracy. If so, she and the security forces failed, losing control in the part of the city where Ms. Merkel was born in 1954, weeks before her parents moved east to Communist Germany.

So this was always going to be risky for Ms. Merkel, and Mr. Trump’s presence has only intensified what were widely anticipated to be widespread and sometimes violent demonstrations against globalization, even though Mr. Trump is a sharp critic of globalization.

Whether the criticism of holding the summit meeting here will hurt Ms. Merkel in the September elections is not clear. Her popular conservative finance minister, Wolfgang Schäuble, appeared on national television on Friday night strongly defending the decision. Only large cities like the picturesque Hanseatic port have sufficient infrastructure to host the thousands of leaders, delegates, journalists and lobbyists who gather at a G-20 meeting, he said.

And some diplomatic work has been done at the summit meeting, even beyond Mr. Trump’s own meetings and his hyperbolic praise of every leader he meets, whatever his private views, including Ms. Merkel (“You have been amazing and you have done a fantastic job.”)

Working overnight, diplomats first agreed on a common text on trade, with a nod toward Mr. Trump’s “America First” demands for restrictions on unfair trade, but had great difficulty on climate, with the Americans demanding a reference to the use of fossil fuels.

The trade section in the statement the aides thrashed out read: “We will keep markets open noting the importance of reciprocal and mutually advantageous trade and investment frameworks and the principle of nondiscrimination, and continue to fight protectionism including all unfair trade practices and recognize the role of legitimate trade defense instruments in this regard.”

The climate section is more of a dodge. It takes note of the American decision to withdraw from the Paris accord and says the other countries nonetheless regard the deal as “irreversible.”

It then nods toward fossil fuels, saying: “The United States of America states it will endeavor to work closely with other countries to help them access and use fossil fuels more cleanly and efficiently and help deploy renewable and other clean energy sources, given the importance of energy access and security in their nationally determined contributions.”

Mr. Trump, who spent so much time with Mr. Putin on Friday that he delayed meeting the British prime minister, Theresa May, until Saturday, tried to fortify her delicate political fortunes. He said that they had had “tremendous talks” on trade and were working on a “very powerful” trade deal for a post-“Brexit” Britain that could be completed “very, very quickly.”

It is not clear what Mr. Trump meant, since the two sides cannot sign such an agreement until after Britain leaves the European Union, in March 2019 at the soonest.

Mr. Trump also confirmed that he would eventually make a state visit to Britain, but the dates continue to be unclear. Mrs. May conveyed the invitation from Queen Elizabeth II within days of Mr. Trump’s inauguration, but there are likely to be significant protests whenever he visits.

Also on Saturday, American officials said that Mr. Trump would direct the State Department to redirect $50 million from its foreign-aid budget to a new international public-private partnership to aid midsize businesses run by women, a group that his daughter Ivanka Trump helped create.

The partnership aims to “help women in developing countries gain increased access to the finance, markets and networks necessary to start and grow a business,” a spokesman for Ms. Trump said.

The contribution comes as the Trump administration considers a drastic scaling-back of foreign aid as part of Mr. Trump’s “America First” campaign pledge to target federal funding to create jobs at home.

His budget, released in April but largely ignored on Capitol Hill, would include deep cuts to the United States Agency for International Development, a major conduit for foreign assistance.</s>HAMBURG, Germany — World powers lined up against President Donald Trump on climate change Saturday, reaffirming their support for international efforts to fight global warming.

The final statement of the Group of 20 summit in Hamburg, Germany, underlined that the other countries and the European Union supported the Paris climate agreement rejected by Trump. They called the deal to reduce greenhouse gases "irreversible" and vowed to implement it quickly and without exception.

The other countries, from European powers such as Germany to emerging ones such as China and energy producers such as Saudi Arabia, dismissively "took note" of the U.S. position, which was boxed off in a separate paragraph that the summit host, German Chancellor Angela Merkel, made clear applied only to the United States.

She said the U.S. position was "regrettable" but that the summit had achieved "good results in some areas," and cited a hard-won agreement on trade that does include Trump and the United States.

On trade, difficult talks yielded the preservation of the G-20's condemnation of protectionism, a statement that has been a hallmark of the group's efforts to combat the global financial crisis and the aftereffects of the Great Recession.

The group added new elements, however: an acknowledgment that trade must be "reciprocal and mutually advantageous" and that countries could use "legitimate trade defense instruments" if they are being taken advantage of.

That echoes concerns raised by Trump, who was attending his first G-20. He has said trade must be fair as well as open and must benefit American companies and workers. He has focused on trade relationships where other countries run large surpluses with the U.S., meaning they sell more to U.S. consumers than they buy from American companies.

More broadly, concerns about trade and its impact on workers figured large in the 2016 U.S. presidential election and in Britain's referendum vote to leave the European Union, a free-trade bloc.

Yet pro-trade officials from the European Union pointed out that the language in the G-20 statement contains no departure from the current global system of regulation, which already allows countries to take defensive measures within the rules of the World Trade Organization. Those can include import taxes that offset unfair practices such as government subsidies or below-cost pricing.

The EU demonstrated its willingness to move ahead with free trade despite Trump by announcing a trade agreement with Japan on the eve of the summit.

On climate, summit deputies hashed out a three-part fudge that everyone could sign. That meant a first section with a broad pledge to fight climate change in general; a separate paragraph carved out that acknowledged the U.S. did not support the Paris deal; and a third paragraph in which the other 19 members reaffirmed their support for the deal.

The results of the summit aren't absolutely decisive, on either the trade or the climate issue. The no-protection pledge was often violated, increasingly in harder-to-detect ways such as tax breaks for home industries rather than obvious import taxes. Meanwhile, failure to agree on climate doesn't stop countries from moving ahead in meeting the Paris agreement's goals, or exceed them if they want to. Additionally, U.S. states and private companies can pursue lower emissions on their own.

G-20 agreements are statements of intent and rely on governments themselves to follow through. Still, they set the tone for global policymaking and enable peer pressure when they're not followed.</s>President Donald Trump emerged from the G-20 summit in Germany isolated from every other major economy on climate change, but the White House nonetheless scored small victories during the meeting.

After a tense round of negotiations, G-20 nations on Saturday reached a compromise on climate change, the last remaining issue of contention at the summit. Every country except the United States declared that the Paris climate change agreement is “irreversible” and must be implemented “swiftly.” The U.S., on the other hand, declared its intention to pull out of the 2015 deal, which has won the backing of nearly 200 nations.

Several countries, including France, had objected to the United States' insistence on mentioning fossil fuels in the G-20's joint communique, leading to an eleventh-hour round of talks.

In the end, the United States appeared to win that fight, keeping the reference to fossil fuels, while pairing it with a call to use renewable energy.

"The United States of America states it will endeavor to work closely with other countries to help them access and use fossil fuels more cleanly and efficiently and help deploy renewable and other clean energy sources, given the importance of energy access and security in their nationally-determined contributions,” the joint communique says.

Administration officials hailed the language as a victory, with one telling POLITICO the U.S. “scored big.”

“It’s nearly unprecedented to have text in a document like this one referring to what only one country believes. In that respect, it’s a vacuous victory for the U.S., since it only confirms what everyone already knew they believe,” said former State Department climate change adviser Andrew Light. “If anything, it only indicates the knots this administration will tie itself into in order to try to simultaneously appear to be appeasing their base and not alienating the rest of the world.”

The United States also used the G-20 communique to underscore its intention to withdraw from the Paris climate deal and scrap former President Barack Obama’s domestic emissions reduction plan (known in United Nations parlance as a “nationally determined contribution), while stressing that it hopes to continuing working with other countries.

“The United States of America announced it will immediately cease the implementation of its current nationally-determined contribution and affirms its strong commitment to an approach that lowers emissions while supporting economic growth and improving energy security needs,” the text says.

Foreign diplomats hope this language leaves room for the United States to remain in or rejoin the Paris deal if Trump writes a new domestic climate plan that reflects his priorities.

The 19 other G-20 nations all underscored their support for the Paris agreement, and endorsed a broad German-backed climate and energy plan, which includes a detailed roadmap for reducing emissions.

The unity is a coup for German Chancellor Angela Merkel, who sought to minimize disagreements among the rest of the G-20 amid U.S. opposition to the Paris agreement. There had been some speculation that Saudi Arabia and Turkey might object to certain portions of the climate language, but Merkel and other leaders worked to ensure they were on board.

Still, that language was weakened slightly in the final negotiations, as part of what one diplomat called a “tit-for-tat” with the United States. A previous draft version of the text said countries “agree” that the Paris deal is “irreversible.” The final version uses less firm language, a seemingly minor tweak that caught the attention of some U.S. officials and foreign diplomats.

“The Leaders of the other G20 members state that the Paris Agreement is irreversible,” the communique says.

G-20 countries similarly insisted that the United States use the word “state” to characterize its position, worrying that stronger language could imply broader agreement among other nations.

The U.S. has been an outsider on climate change at international talks since Trump took office.

At the May G-7 meeting in Italy, the U.S. declined to join other countries in backing the Paris deal, saying it was in the process of reviewing its policies. After Trump’s June announcement that he intends to withdraw from the Paris agreement, the U.S. position was relegated to a footnote in a joint statement released after a G-7 environment ministers meeting in Germany last month.</s>HAMBURG (Reuters) - Leaders from the world’s leading economies broke with U.S. President Donald Trump on climate policy at a G20 summit on Saturday, in a rare public admission of disagreement and blow to multilateral cooperation.

German Chancellor Angela Merkel, keen to show off her skills as a mediator two months before a German election, achieved her primary goal at the meeting in Hamburg, convincing her fellow leaders to support a single communique with pledges on trade, finance, energy and Africa.

But the divide between Trump, elected on a pledge to put “America First”, and the 19 other members of the club, including countries as diverse as Japan, Saudi Arabia and Argentina, was stark.

Last month Trump announced he was pulling the United States out of a landmark international climate accord clinched two years ago in Paris.

“In the end, the negotiations on climate reflect dissent – all against the United States of America,” Merkel told reporters at the end of the meeting.

“And the fact that negotiations on trade were extraordinarily difficult is due to specific positions that the United States has taken.”

The summit, marred by violent protests that left the streets of Hamburg littered with burning cars and broken shop windows, brought together a volatile mix of leaders at a time of major change in the global geo-political landscape.

Trump’s shift to a more unilateral, transactional diplomacy has left a void in global leadership, unsettling traditional allies in Europe and opening the door to rising powers like China to assume a bigger role.

Tensions between Washington and Beijing dominated the run-up to the meeting, with the Trump administration ratcheting up pressure on President Xi Jinping to rein in North Korea and threatening punitive trade measures on steel.

TRUMP-PUTIN

Trump met Russian President Vladimir Putin for the first time in Hamburg, a hotly anticipated encounter after the former real estate mogul promised a rapprochement with Moscow during his campaign, only to be thwarted by accusations of Russian meddling in the vote and investigations into the Russia ties of Trump associates.

Putin said at the conclusion of the summit on Saturday that Trump had quizzed him on the alleged meddling in a meeting that lasted over two hours but seemed to have been satisfied with the Kremlin leader’s denials of interference.

Trump had accused Russia of destabilizing behavior in Ukraine and Syria before the summit. But in Hamburg he struck a conciliatory tone, describing it as an honor to meet Putin and signaling, through Secretary of State Rex Tillerson, that he preferred to focus on future ties and not dwell on the past.

“It was an extraordinarily important meeting,” Tillerson said, describing a “very clear positive chemistry” between Trump and the former KGB agent.

In the final communique, the 19 other leaders took note of the U.S. decision to withdraw from the Paris climate accord and declared it “irreversible”.

For its part, the United States injected a contentious line saying that it would “endeavor to work closely with other countries to help them access and use fossil fuels more cleanly and efficiently.”

French President Emmanuel Macron led a push to soften the U.S. language.

“There is a clear consensus absent the United States,” said Thomas Bernes, a distinguished fellow at the Centre for International Governance Innovation. “But that is a problem. Without the largest economy in the world how far can you go?”

Jennifer Morgan, executive director at Greenpeace, said the G19 had “held the line” against Trump’s “backward decision” to withdraw from Paris.

On trade, another sticking point, the leaders agreed they would “fight protectionism including all unfair trade practices and recognize the role of legitimate trade defense instruments in this regard.”

The leaders also pledged to work together to foster economic development in Africa, a priority project for Merkel.

VIOLENT PROTESTS

Merkel chose to host the summit in Hamburg, the port city where she was born, to send a signal about Germany’s openness to the world, including its tolerance of peaceful protests.

It was held only a few hundred meters from one of Germany’s most potent symbols of left-wing resistance, a former theater called the “Rote Flora” which was taken over by anti-capitalist squatters nearly three decades ago.

Over the three days of the summit, radicals looted shops, torched cars and lorries. More than 200 police were injured and some 143 people have been arrested and 122 taken into custody.

Some of the worst damage was done as Merkel hosted other leaders at for a concert and lavish dinner at the Elbphilharmonie, a modernist glass concert hall overlooking the Elbe River.

Merkel met police and security force after the summit to thank them, and condemned the “unbridled brutality” of some of the protestors, but she was forced to answer tough questions about hosting the summit in Hamburg during her closing press conference.</s>SACRAMENTO, Calif.
