Things Have Gotten Much Worse Since An Inconvenient TruthMaddie Stone5/24/16 2:50pmFiled to: climate changeal goreParis agreementclimateearth sciencesenvironmentenergy58044EditPromoteShare to KinjaToggle Conversation toolsGo to permalinkGlobally averaged temperature anomalies in 2015. Image: NOAAIn 2006, Al Gore’s An Inconvenient Truth spread the idea of human-caused climate change far and wide in what is now considered a watershed moment for the science. But today, on the ten-year anniversary of the film’s release, we’ve made little progress toward addressing the grave planetary concerns Gore raised. In fact, by practically every metric, things have gotten much worse.AdvertisementOver the past decade, humanity’s climate-warming carbon emissions have risen steadily, from 8.3 billion tons in 2006 to roughly 10 billion tons last year. The concentration of CO2 in our atmosphere has grown in step, briefly topping the historic 400 parts per million (ppm) milestone for the first time in 2013. Then, last spring, atmospheric CO2 rose to 400 ppm for an entire month. Now we are on the verge of living in a world where 400 ppm or greater is the permanent state of our atmosphere, something that hasn’t happened in millions of years.Top: Estimated global anthropogenic carbon emissions, via Boden, TA, Marland, G and Andres, RJ 2013.

Graphic by Maddie Stone.The consequences for our climate have been stark. The year of An Inconvenient Truth’s release was the hottest in recorded history, but just four years later, it was overtaken by 2010. 2010 held the heat record for three years, before 2014 came along and took the crown handily, only to have its record shattered by 2015. Now, a mere five months in, scientists are already calling 2016 the hottest year yet. And it’s not just annual records that are being broken like New Year’s resolutions: every month for the last 12 has marked a heat record, too.

More extreme storms, droughts, heat waves, and fires. Ocean acidification. A mass die-off of Earth’s coral reefs. A sixth mass extinction. If any of these sound familiar, it’s because all of them have become our reality, with increasingly devastating outcomes for human society. The future predicted by science and broadcast by the likes of Gore is already here.NASA, NOAA, and UK Met Office global temperature anomalies, dating back to 1880.

Last month, leaders of 175 countries met to sign the Paris Climate Agreement, which resolves to limit global warming to 2 degrees Celsius, a ceiling that will hopefully allow us to avoid the most catastrophic impacts of climate change. But the actual pledges contained in the Paris Agreement don’t get us anywhere close to where we need to be to prevent oblivion.
