вЂњAs you can imagine, behind the scenes there were some people who were a little uncomfortable because it veered away from the true science. вЂњWe have been publishing papers for the last 20 to 30 years, documenting the train wreck of climate change,вЂќ he says. Publishing that plea was a departure for some of the scientists, Filippelli says. вЂњThe time to bridge the divide between scientist and citizen, head and heart, is now.вЂќ вЂњWe are scientists, but we also have families and loved ones alongside our fellow citizens on this planet,вЂќ the letter states. Theyurged world leaders at COP26 to keep the вЂњdevastating impactsвЂќ of climate change in check by immediately reducing global carbon emissions and shifting to a green economy. On October 26, Filippelli, the editor of the American Geophysical Union journal GeoHealth, and editors in chief of other journals published by the organization coauthored a statement in Geophysical Research Letters. вЂњIвЂ™m hoping that the collision of the science and the statistics in the gap analysis, and the voices of the people will promote a greater sense of urgency,вЂќ says Gabriel Filippelli, a geochemist at Indiana UniversityвЂ“Purdue University Indianapolis. To hold warming to 1.5 degrees C requires a roughly 55 percent drop in emissions compared with the latest pledges, to about 25 gigatons a year.

But to stay on track for 2 degrees C of warming, emissions would have to be about 30 percent lower than the new pledges, or about 39 gigatons each year. With the new pledges, total annual emissions in 2030 would be 7.5 percent lower (about 55 gigatons of carbon dioxide equivalent) than they would have been with pledges as of last year (about 59 gigatons). The 2021 report finds that new commitments bring the world only slightly closer to where emissions need to be by 2030 to reach warming targets. Ahead of the COP26 meeting, 120 countries, responsible for emitting just over half of the worldвЂ™s greenhouse gas emissions, announced their new commitments to address climate change by 2030. Environment Programme has kept annual tabs on the still-yawning gap between existing national pledges to reduce emissions and the Paris Agreement target ( SN: 11/26/19). The COP26 meeting - postponed from 2020 to 2021 due to the COVID-19 pandemic - holds particular significance because it is the first COP meeting since the 2015 agreement in which signatories are expected to significantly ramp up their emissions reductions pledges. Climate Change Conference, or COP26, in Glasgow, Scotland. report comes at a crucial time, just days before world leaders meet for the 2021 U.N. вЂњThe era of half measures and hollow promises must end.вЂќ In its latest report, released in August, the IPCC noted that extreme weather events, exacerbated by human-caused climate change, now occur in every part of the planet - and warned that the window to reverse some of these effects is closing ( SN: 8/9/21).Дespite these dire warnings, вЂњthe parties to the Paris Agreement are utterly failing to keep target in reach,вЂќ said U.N. Restricting global warming further, to just 1.5 degrees C, would forestall many more devastating consequences of climate change, as the Intergovernmental Panel on Climate Change, or IPCC, reported in 2018 ( SN: 12/17/18). officials stated at a news event for the reportвЂ™s release.ДЄt a landmark meeting in Paris in 2015, 195 nations pledged to eventually reduce their emissions enough to hold global warming to well below 2 degrees C by 2100 ( SN: 12/12/15). But that still falls short of the mark, U.N.

The Emissions Gap Report 2021: The Heat Is On, released October 26, reveals that current pledges to reduce greenhouse gas emissions and rein in global warming still put the world on track to warm by 2.7 degrees Celsius above preindustrial levels by the end of the century.ДЄiming for вЂњnet-zero emissionsвЂќ by midcentury - a goal recently announced by China, the United States and other countries, but without clear plans on how to do so - could reduce that warming to 2.2 degrees C. But the worldвЂ™s nations are failing to meet the moment, states a new report by the United Nations Environment Programme. This year was supposed to be a turning point in addressing climate change.
