If you look at the supplemental info, note that this year is well on track to be bracketed within the top ten hottest years on record:&lt;p&gt;&amp;gt; &amp;quot;This graphic compares the year-to-date temperature anomalies for 2021 (black line) to what were ultimately the ten warmest years on record: 2016 (1st), 2020 (2nd), 2019 (3rd), 2015 (4th), 2017 (5th), 2018 (6th), 2014 (7th), 2010 (8th), 2013 (9th), and 2005 (10th).&amp;quot;&lt;p&gt;Now,  consider the lag effect on climate response and atmospheric forcing (i.e. the ocean absorbs a fair amount of the extra heat, but as the ocean warms, that heat gets injected back into the atmosphere, especially polewards, so there&amp;#x27;s a lag time before current atmospheric forcings are full realized, and that&amp;#x27;s a multidecade effect, so we won&amp;#x27;t feel today&amp;#x27;s forcing completely for decades, even a century).&lt;p&gt;Conclusion as I see it: every year for the next 50 years is going to be bracketed in the top ten hottest years, meaning the years 2030-2040 will all be hotter than 2010-2020 and so on.  Decade by decade for the rest of the lives of people alive today, this will continue - and while getting off fossil fuels is needed, is indeed the only way to slow this trend, it&amp;#x27;s only going to slow down the year-to-year increase.&lt;p&gt;Additionally, as polar melt proceeds, permafrost melt and outgassing becomes self-sustaining even if humans completely stop fossil fuel use and deforestation.&lt;p&gt;Practically, this means adaptation is simply a must.  People have to move out of flood plains, waste treatment plants in low-lying coastal zones needed to be moved uphill, people need to realize the global refugee crisis is going to be 10X as bad as anything seen yet at least, perhaps a steady rate of 1,000,000 per year fleeing climate disaster zones.&lt;p&gt;In reality we are heading back to climate conditions last seen ~3-5 million years ago, before the ice ages set in, with sea levels dozens of meters higher than they are now. Nobody likes to hear this it seems, but the science does seem to be saying that this has already happened, sort of.</text></comment>

They just redid the climate.gov website to be more useful: &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.climate.gov&amp;#x2F;&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.climate.gov&amp;#x2F;&lt;/a&gt;</text></comment>
