There are a myriad of other radiative forcings that affect the planet's energy imbalance. | If the sheet were to break down, ocean levels would rise by several metres in a relatively geologically short period of time, perhaps a matter of centuries. | 1 |
The amount of heat energy coming out of the Earth is too small to even be worth considering. | Because much of the heat is provided by radioactive decay, scientists postulate that early in Earth's history, before isotopes with short half-lives were depleted, Earth's heat production was much higher. | 0 |
Greenland has only lost a tiny fraction of its ice mass. | Between then and 2010, the mountain lost 80 percent of its ice — two-thirds of which since another scientific expedition in the 1970s. | 0 |
It is clear, then, that greening is emerging as a factor with the potential to blunt some of the worst impacts of human greenhouse gas emissions. | Globally there are an estimated 7.7 million jobs associated with the renewable energy industries, with solar photovoltaics being the largest renewable employer. | 1 |
Lindzen and Choi’s paper is viewed as unacceptably flawed by other climate scientists. | Worst of all, we have driven the rate of biological extinction, the permanent loss of species, up several hundred times beyond its historical levels, and are threatened with the loss of a majority of all species by the end of the 21st century." | 1 |
at the end of recent ice ages, the concentration of carbon dioxide in the atmosphere started to rise only after temperatures began to climb. | In the deep ocean, the predominant driving force is differences in density, caused by salinity and temperature variations (increasing salinity and lowering the temperature of a fluid both increase its density). | 1 |
Global human emissions are only 3 per cent of total annual emissions. | At this CO 2 concentration, International Space Station crew experienced headaches, lethargy, mental slowness, emotional irritation, and sleep disruption. | 1 |
While the north-east, midwest and upper great plains have experienced a 30% increase in heavy rainfall episodes – considered once-in-every-five year downpours – parts of the west, particularly California, have been parched by drought. | "Antarctica ice melt has accelerated by 280% in the last 4 decades". | 1 |
Venus doesn't have a runaway greenhouse effect | According to the United States National Research Council, [T]here is a strong, credible body of evidence, based on multiple lines of research, documenting that climate is changing and that these changes are in large part caused by human activities. | 1 |
This means it is possible that by some yardsticks, 2016 will be declared as hot as 2015 or even slightly hotter – because El Nino did not vanish until the middle of the year. | The El Niño event also contributed to the Earth's warming trend, with 2014 and 2015 being two of the warmest years on record. | 0 |
"Mike's Nature trick" has nothing to do with "hide the decline", instead refering to a technique by Michael Mann to plot instrumental temperature along with past reconstructions. | Sea ice coverage in the Arctic has shrunk at a much faster rate than it has expanded in the Southern Ocean. | 1 |
While there are minor errors in An Inconvenient Truth, the main truths presented - evidence to show mankind is causing global warming and its various impacts is consistent with peer reviewed science. | All 19 climate scientists who had seen the movie or had read the homonymous book said that Gore accurately conveyed the science, with few errors. | 0 |
The Great Barrier Reef is experiencing the most widespread bleaching ever recorded | "From new estimates of the combined anthropogenic forcing due to greenhouse gases, aerosols, and land surface changes, it is extremely likely (>95%) that human activities have exerted a substantial net warming influence on climate since 1750." | 1 |
Not only is there no scientific evidence that CO2 is a pollutant, higher CO2 concentrations actually help ecosystems support more plant and animal life. | At very high concentrations (100 times atmospheric concentration, or greater), carbon dioxide can be toxic to animal life, so raising the concentration to 10,000 ppm (1%) or higher for several hours will eliminate pests such as whiteflies and spider mites in a greenhouse. | 0 |
There is ample evidence that Earth's average temperature has increased in the past 100 years and the decline of mid- and high-latitude glaciers is a major piece of evidence. | There is considerable evidence that over the very recent period of the last 100–1000 years, the sharp increases in human activity, especially the burning of fossil fuels, has caused the parallel sharp and accelerating increase in atmospheric greenhouse gases which trap the sun's heat. | 0 |
Over 97 percent of the scientific community ⦠believe that humans are contributing to climate change. | Currently, through land development, combustion of fossil fuels, and pollution, humans are thought to be the main contributor to global climate change. | 0 |
"The 30 major droughts of the 20th century were likely natural in all respects; and, hence, they are "indicative of what could also happen in the future," as Narisma | Multiple independently produced instrumental datasets confirm that the 2009–2018 decade was 0.93 ± 0.07 °C warmer than the pre-industrial baseline (1850–1900). | 1 |
There is a link between climate change and the NSW bushfires. | The warming evident in the instrumental temperature record is consistent with a wide range of observations, documented by many independent scientific groups; for example, in most continental regions the frequency and intensity of heavy precipitation has increased. | 1 |
“‘If you remove the ice shelf, there’s a potential that not just ice-cliff instabilities will start occurring, but a process called marine ice-sheet instabilities,’ says Matthew Wise, a polar scientist at the University of Cambridge. | The WAIS is classified as a marine-based ice sheet, meaning that its bed lies well below sea level and its edges flow into floating ice shelves. | 0 |
Tuvalu sea level isn't rising. | Tuvaluan leaders have been concerned about the effects of rising sea levels. | 0 |
The world’s alpine glaciers recorded a net annual loss of ice for the 36th consecutive year and the Greenland ice sheet … experienced melting over more than 50% of its surface. | Arctic amplification also causes methane to be released as permafrost melts, which is expected to surpass land use changes as the second strongest anthropogenic source of greenhouse gases by the end of the century. | 1 |
As a result, "The warmest year on US record is now 1934. | The U.S. had its warmest March–May on record in 2012. | 0 |
The Great Barrier Reef is experiencing the most widespread bleaching ever recorded | The Car of Tomorrow was first tested in December 2005, and was first revealed to the public in 2006, with numerous safety improvements being touted. | 1 |
Alaska Sen. Mark Begich "is on record supporting a carbon tax, even pushing Harry Reid to make it a priority." | The extent of sea ice around Antarctica (in terms of square kilometers of coverage) has remained roughly constant in recent decades, although the amount of variation it has experienced in its thickness is unclear. | 1 |
Gov. Palin ... is somebody who actually doesn't believe that climate change is man-made. | The sensitivity of temperature to atmospheric gasses, most notably CO 2, is often expressed in terms of the change in temperature per doubling of the concentration of the gas. | 1 |
The acceleration is making some scientists fear that Antarctica’s ice sheet may have entered the early stages of an unstoppable disintegration. | With rising global temperatures, the amount of permafrost melting and releasing methane continues to increase. | 1 |
The science is clear, climate change is making extreme weather events, including tornadoes, worse. | This could lead to changing, and for all emissions scenarios more unpredictable, weather patterns around the world, less frost days, more extreme events (droughts and storm or flood disasters), and warmer sea temperatures and melting glaciers causing sea levels to rise. | 0 |
Melting ice isn't warming the Arctic. | These high-priority agents pose a risk to national security, can be easily transmitted and disseminated, result in high mortality, have potential major public health impact, may cause public panic, or require special action for public health preparedness. | 1 |
The clearest of these is simple accounting - humans are emitting CO2 at a rate twice as fast as the atmospheric increase (natural sinks are absorbing the other half). | The oceans act as an enormous carbon sink, and have taken up about a third of CO 2 emitted by human activity. | 0 |
And there is a lot of evidence that climate change is diminishing biodiversity, which can be seen in these alpine meadows as well. | Increased temperatures may allow herbivores to expand further into alpine regions, significant impacting the composition of alpine herbfields. | 0 |
The Petition Project features over 31,000 scientists signing the petition stating "there is no convincing scientific evidence that human release of carbon dioxide will, in the forseeable future, cause catastrophic heating of the Earth's atmosphere". | 7–10 "There is now convincing evidence that since the industrial revolution, human activities, resulting in increasing concentrations of greenhouse gases have become a major agent of climate change. | 0 |
North America suffers extreme weather events including wildfires, drought, and heatwaves. | Another example is the possibility for the Atlantic Meridional Overturning Circulation to slow or shut down (see also shutdown of thermohaline circulation). | 1 |
The contrast in precipitation between wet and dry regions and between wet and dry seasons will increase, although there may be regional exceptions. | There was high agreement and much evidence that a substantial fraction of these mitigation costs may be offset by benefits to health as a result of reduced air pollution, and that there would be further cost savings from other benefits such as increased energy security, increased agricultural production, and reduced pressure on natural ecosystems as well as, in certain countries, balance of trade improvements, provision of modern energy services to rural areas and employment. | 1 |
Clearly, other factors besides atmospheric carbon influence earth temperatures and global warming." | In the scientific literature, there is an overwhelming consensus that global surface temperatures have increased in recent decades and that the trend is caused mainly by human-induced emissions of greenhouse gases. | 0 |
there is no relationship between temperature and carbon dioxide emissions by Âhumans[...] | A consensus, based on current evidence, now exists within the global scientific community that human activities are the main source of climate change and that the burning of fossil fuels is largely responsible for driving this change... | 0 |
When you account for the effects which are not reflected in the market price of fossil fuels, like air pollution and health impacts, the true cost of coal and other fossil fuels is higher than the cost of most renewable energy technologies. | "Climate-change–driven accelerated sea-level rise detected in the altimeter era". | 1 |
[Jonathan Overpeck:] ‘No doubt about it anymore — humans, mainly by burning fossil fuels, are cooking the planet,’ Overpeck said. | These measurements came from the US space agency's GRACE (Gravity Recovery and Climate Experiment) satellite, launched in 2002, as reported by BBC. | 1 |
Extreme weather isn't caused by global warming | "Cosmic rays blamed for global warming". | 1 |
Because oxygen in the global ocean is not evenly distributed, the 2 percent overall decline means there is a much larger decline in some areas of the ocean than others. | The ocean has already lost oxygen, throughout the entire water column and oxygen minimum zones are expanding worldwide. | 0 |
Humans are too insignificant to affect global climate. | Humans have had a dramatic effect on the environment. | 0 |
Every four minutes, another American home or business goes solar. | The wheel moves continuously, removing garbage and dumping it into an attached dumpster using only hydro and solar renewable power to keep its wheel turning. | 0 |
Preventing global warming is relatively cheap; business-as-usual will cause accelerating climate damage costs that economists struggle to even estimate. | The total economic impacts from climate change are difficult to estimate. | 0 |
"The Keeling curve, which is widely used to show the increase in CO2 emissions, is based on data from the top of Mount Mauna Loa in Hawaii. | The Keeling Curve is a graph of the accumulation of carbon dioxide in the Earth's atmosphere based on continuous measurements taken at the Mauna Loa Observatory on the island of Hawaii from 1958 to the present day. | 0 |
Global warming' is a myth — so say 80 graphs from 58 peer-reviewed scientific papers published in 2017. | His 1861 paper proposed changing concentrations of these gases could have caused "all the mutations of climate which the researches of geologists reveal" and would explain ice age changes. | 0 |
Humans are too insignificant to affect global climate. | The largest human influence has been the emission of greenhouse gases such as carbon dioxide, methane, and nitrous oxide. | 0 |
In fact, the global melt rate has been accelerating since the mid-1970s. | This effect results in the increased absorption of radiation that accelerates melting." | 0 |

More than 260,000 Americans are employed by the domestic solar industry â three times as many workers as employed by the entire coal mining industry. | At the same time, the solar power industry grew by almost a quarter to 374,000 jobs. | 0 |
The noted oceanographer Walter Munk referred to sea-level rise as an “enigma” | Over the 21st century, the IPCC projects that in a very high emissions scenario the sea level could rise by 61–110 cm. | 1 |
Carbon dioxide is a trace gas.” | Carbon dioxide in Earth's atmosphere is a trace gas, currently (mid 2018) having a global average concentration of 409 parts per million by volume (or 622 parts per million by mass). | 0 |
Discovery Of Massive Volcanic CO2 Emissions Discredits Global Warming Theory. | Sometime during the 21st century, sea ice may effectively cease to exist during the summer. | 1 |
Together, these two unaltered [sea level] datasets indicate that global mean sea level trend has remained stable over the entire period 1992-2007, altogether eliminating the apparent 3.2 mm/year rate of sea-level rise arising from the “adjusted” data. | The New York Times reported that "the leading international network of climate scientists has concluded for the first time that global warming is 'unequivocal' and that human activity is the main driver, 'very likely' causing most of the rise in temperatures since 1950". | 1 |
The costs of inaction far outweigh the costs of mitigation. | According to the Stern Review, inaction can be as high as the equivalent of losing at least 5% of global gross domestic product (GDP) each year, now and forever (upto 20% of the GDP or more when including a wider range of risks and impacts), whereas mitigating climate change will only cost about 2% of the GDP. | 0 |
The temperatures are expected to change by as much as 10 Fahrenheit degrees at different places of the globe. | At the center, the temperature may be up to 6,000 °C (10,830 °F), and the pressure could reach 360 GPa (52 million psi). | 0 |
“There is now less sea ice on Earth than at any time on record. | As is stated in Article 2 of the Convention, this requires that greenhouse gas (GHG) concentrations are stabilized in the atmosphere at a level where ecosystems can adapt naturally to climate change, food production is not threatened, and economic development can proceed in a sustainable fashion. | 1 |
global warming ceased around the end of the twentieth century and was followed (since 1997) by 19 years of stable temperature. | Play media Satellite measurements of Greenland's ice cover from 1979 to 2009 reveals a trend of increased melting. | 1 |
Losing tropical forests is not somehow cheaper than putting up wind farms in the US or Sahara.” | Nearly all publishing climate scientists (97–98%) support the consensus on anthropogenic climate change, and the remaining 3% of contrarian studies either cannot be replicated or contain errors. | 1 |
Great Barrier Reef may perish by 2030s | At current emission rates, temperatures could increase by 2 °C, which the United Nations' Intergovernmental Panel on Climate Change (IPCC) designated as the upper limit to avoid "dangerous" levels, by 2036. | 1 |
The temporary drop in sea level in 2010 was due to intense land flooding caused by a strong La Nina. | Meanwhile, a series of major storms caused extensive flooding in California in December 2010, with seven consecutive days of non-stop rainfall, leading to one of the wettest Decembers in over 120 years of records. | 0 |
The effects of enhanced CO2 on terrestrial plants are variable and complex and dependent on numerous factors. | Increasing atmospheric carbon dioxide certainly affects plant morphology and is acidifying oceans, and temperature affects species ranges, phenology, and weather, but, mercifully, the major impacts that have been predicted are still potential futures. | 0 |
Sea ice has diminished much faster than scientists and climate models anticipated. | However scientists have found that ice is being lost, and at an accelerating rate. | 0 |
Warming trends agree well with surface temperatures and model predictions except near the Poles. | In the tropics the net effect is to produce a significant warming, while at latitudes closer to the poles a loss of albedo leads to an overall cooling effect. | 0 |
In 1990 the United Nation’s Intergovernmental Panel on Climate Change (IPCC) predicted that temperatures would rise by 0.54F (0.3C) per decade. | They predict that under a "business as usual" (BAU) scenario, global mean temperature will increase by about 0.3 °C per decade during the [21st] century. | 0 |
'To suddenly label CO2 as a "pollutant" is a disservice to a gas that has played an enormous role in the development and sustainability of all life on this wonderful Earth. | The statement stresses that the scientific understanding of climate change is now sufficiently clear to justify nations taking prompt action, and explicitly endorsed the IPCC consensus. | 1 |
global warming ceased around the end of the twentieth century and was followed (since 1997) by 19 years of stable temperature | The average global temperature on Earth has increased by about 0.8° Celsius (1.4° Fahrenheit) since 1880; Two-thirds of the warming has occurred since 1975, at a rate of roughly 0.15-0.20 °C per decade. | 0 |
Venus doesn't have a runaway greenhouse effect | Global warming is a major threat to global biodiversity. | 1 |
In our lifetime, there has been no correlation between carbon dioxide emissions and temperature | However scientists have found that ice is being lost, and at an accelerating rate. | 1 |
While methane is a more potent greenhouse gas than CO2, there is over 200 times more CO2 in the atmosphere. | That is, over a 20-year period, it traps 84 times more heat per mass unit than carbon dioxide (CO2) and 32 times the effect when accounting for aerosol interactions. | 0 |
Comparisons to the most recent data consistently finds that climate change is occurring more rapidly and intensely than indicated by IPCC predictions. | Human activity since the Industrial Revolution has increased the amount of greenhouse gases in the atmosphere, leading to increased radiative forcing from CO2, methane, tropospheric ozone, CFCs, and nitrous oxide. | 1 |
it later emerged that its creator Dr Michael Mann had spliced too [sic] datasets together – tree-rings showing temperatures going back hundreds of years, then recent thermometer readings for the more recent decades. | They also found that galactic cosmic rays, and total solar irradiance did not have any statistically significant influence on changes in cloud cover. | 1 |
As it happens, the writer of that October 2009 e-mail—Kevin Trenberth, a lead author of the warmist bible, the 2007 Intergovernmental Panel on Climate Change (IPCC) report—told Congress two years ago that evidence for manmade warming is "unequivocal. | Retrieved 2010-08-28. the leading international network of climate scientists has concluded for the first time that global warming is 'unequivocal' and that human activity is the main driver, 'very likely' causing most of the rise in temperatures since 1950 Stevens, William K. (2007-02-06). | 0 |
While preventing global warming is relatively cheap, economists can't even accurately estimate the accelerating costs of climate damages if we continue with business-as-usual. | It is also predicted that Greenland will become warm enough by 2100 to begin an almost complete melt during the next 1,000 years or more. | 1 |
“Every day, nature puts twenty times as much carbon dioxide into the atmosphere as all of Earth industries. | Since the Industrial Revolution anthropogenic emissions – primarily from use of fossil fuels and deforestation – have rapidly increased its concentration in the atmosphere, leading to global warming. | 0 |
Greenland's ice loss is accelerating & will add metres of sea level rise in upcoming centuries. | If the Greenland ice sheet were to melt away completely, the world's sea level would rise by more than 7 m (23 ft). | 0 |
Shelters in poorer countries are not repainted as often, and darker stations absorb more of the sun’s energy. | The built environment in urban areas also contributes to the "heat island effect", the phenomenon whereby cities experience higher temperatures due to the predominance of dark, paved surfaces and lack of vegetation. | 0 |
Everybody knows that the Pacific island of Tuvalu is sinking. ... | The contribution of the Greenland ice sheet on sea level over the next couple of centuries can be very high due to a self-reinforcing cycle (a so-called positive feedback). | 1 |
Carbon dioxide is not "a primary contributor to the global warming that we see." | On March 9, 2017, in an interview on CNBC's Squawk Box, Pruitt stated that he "would not agree that" carbon dioxide is "a primary contributor to the global warming that we see" backing up his claim by stating that "measuring with precision human activity on the climate is something very challenging to do and there's tremendous disagreement about the degree of impact." | 0 |
Arctic sea ice loss is three times greater than Antarctic sea ice gain, and the amount of solar energy absorbed by the Earth is increasing as a result. | Many records for snowfall and temperature were broken, many for the month of February, with every state east of the Mississippi River being colder than average, some for the entire winter. | 1 |
A large number of ancient mass extinction events have been strongly linked to global climate change. | Other causal or contributing factors to the extinction may have been the Deccan Traps and other volcanic eruptions, climate change, and sea level change. | 0 |
In particular, satellite data demonstrate for the last 17 years, there's been zero warming. | In March 2015, he said that some people are "global warming alarmists" and, citing satellite temperature measurements, said that there had been no significant warming in 18 years. | 0 |
it’s not a pollutant that threatens human civilization. | In the scientific literature, there is an overwhelming consensus that global surface temperatures have increased in recent decades and that the trend is caused mainly by human-induced emissions of greenhouse gases. | 1 |
The minute increase of anthropogenic CO2 in the atmosphere (0.008%) was not the cause of the warming—it was a continuation of natural cycles that occurred over the past 500 years." | The introduction includes this statement: There is strong evidence that the warming of the Earth over the last half-century has been caused largely by human activity, such as the burning of fossil fuels and changes in land use, including agriculture and deforestation. | 0 |
Human kind has little or nothing to do with the recent temperature changes. | The Environment Agency claimed that the UK may have had the most severe drought in 100 years. | 1 |
Greenland's ice loss is accelerating & will add metres of sea level rise in upcoming centuries. | The glaciers of Greenland are also contributing to a rise in the global sea level faster than was previously believed. | 0 |
But Trenberth’s "lack of warming at the moment" has been going on at least a decade. | Agriculture contributes to climate change by anthropogenic emissions of greenhouse gases, and by the conversion of non-agricultural land such as forest for agricultural use. | 1 |
The sun has gone into ‘lockdown’ which could cause freezing weather, earthquakes and famine, say scientists | "Warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice and rising global average sea level." | 1 |
Ever since 2012, scientists have been debating a complex and frankly explosive idea about how a warming planet will alter our weather — one that, if it’s correct, would have profound implications across the Northern Hemisphere and especially in its middle latitudes | Whether this be due directly to the health, disposition or constitution of our globe itself, or to the weather from without, as the new glacial cosmogony would teach us, must remain a question for experts to debate, if not settle. | 0 |
Global warming is an increasingly urgent problem. | In the three decades following 1978, the combination of solar and volcanic activity is estimated to have had a slight cooling influence. | 1 |
Sea ice has diminished much faster than scientists and climate models anticipated. | The Arctic sea ice September minimum extent (i.e., area with at least 15% sea ice coverage) reached new record lows in 2002, 2005, 2007, and 2012. | 1 |
Ever since 2012, scientists have been debating a complex and frankly explosive idea about how a warming planet will alter our weather — one that, if it’s correct, would have profound implications across the Northern Hemisphere and especially in its middle latitudes | Problems of global warming, climate change, and their various negative impacts on human life and on the functioning of entire societies are one of the most dramatic challenges of modern times. | 0 |
Last month was the hottest June ever recorded, European satellite agency announces | The spatial and temporal fingerprint of warming can be traced to increasing greenhouse gas concentrations in the atmosphere, which are a direct result of burning fossil fuels, broad-scale deforestation and other human activity." | 1 |
The authors seem to have jumped right into statistical analysis without proposing a physical mechanism that works. | For constant humidity they computed a climate sensitivity of 2.3 °C per doubling of CO2 (which they rounded to 2, the value most often quoted from their work, in the abstract of the paper). | 1 |
Different areas of science are understood with varying degrees of certainty. | This realization is the topic of intersubjective verifiability, as recounted, for example, by Max Born (1949, 1965) Natural Philosophy of Cause and Chance, who points out that all knowledge, including natural or social science, is also subjective. | 0 |
“We indicated 23 years ago — in our 1994 Nature article — that climate models had the atmosphere’s sensitivity to CO2 much too high,” Christy said in a statement. | The sensitivity of temperature to atmospheric gasses, most notably CO 2, is often expressed in terms of the change in temperature per doubling of the concentration of the gas. | 0 |
Sea ice has diminished much faster than scientists and climate models anticipated. | Reports have also predicted that within a few decades the Arctic Ocean will be entirely free of ice in the summer. | 1 |
In Alaska, brown bears are changing their feeding habits to eat elderberries that ripen earlier. | Grizzlies in Alaska supplement their diet of salmon and clams with sedge grass and berries. | 0 |
The answer lies in the summer’s record-breaking heat, say wildfire experts. | The fires were associated with record-high temperatures, which were attributed to climate change—the summer had been the hottest recorded in Russian history—and drought. | 0 |
“The Northern Hemisphere jet stream […] flow is stronger when that temperature difference is large. | The strong temperature contrast between polar and tropical air gives rise to the large scale atmospheric circulation cells and the jet stream. | 0 |
The sun has gone into ‘lockdown’ which could cause freezing weather, earthquakes and famine, say scientists | The persistently cold, wet weather caused great hardship, was primarily responsible for the Great Famine of 1315–1317, and strongly contributed to the weakened immunity and malnutrition leading up to the Black Death (1348–1350). | 0 |
Because the collapse of vulnerable parts of the ice sheet could raise the sea level dramatically, the continued existence of the world’s great coastal cities — Miami, New York, Shanghai and many more — is tied to Antarctica’s fate. | Within the G8 group of countries, it is most significant for the UK, France and Germany. | 1 |
