The United Nations’ Environmental Program has released a new with yet more dire news about our odds of avoiding climate disaster caused by greenhouse gas emissions. According to this assessment, the current trajectory of international commitments will see the planet’s temperature increasing 2.6 degrees Celsius or more over the course of this century. That amount of temperature change would lead to more catastrophic and life-threatening weather events.
UN members are due to submit their latest Nationally Determined Contributions ahead of the COP30 conference in Brazil next year. The NDCs lay out each country’s plan for reduced greenhouse gas emissions. One part of the NDCs are to reach the goal set by the Paris Agreement to limit global temperature increases to 1.5 degrees Celsius, and one part targets keeping global temperature increases to within a less ideal 2 degrees Celsius. While the report says it is technically possible to reach the Paris Agreement goal, much larger actions will be required to cut emissions by the necessary amount.
“Increased deployment of solar photovoltaic technologies and wind energy could deliver 27 percent of the total emission reduction potential in 2030 and 38 percent in 2035,” the report gives as an example of what’s still needed. “Action on forests could deliver around 20 percent of the potential in both years.”
“Every fraction of a degree avoided counts in terms of lives saved, economies protected, damages avoided, biodiversity conserved and the ability to rapidly bring down any temperature overshoot,” UN Environment Program Executive Director Inger Andersen wrote in the report’s forward.
International collaboration, government commitments and financial contributions will also be essential for getting back on track to either the 2-degree or 1.5-degree goals. “G20 nations, particularly the largest-emitting members, would need to do the heavy lifting,” the report reads.
If all of this sounds familiar, that’s probably because the UN has issued the same stark warnings in each of its annual reports on emissions for now. And other reports have echoed their calls, such as damning earlier this year that just 57 companies are responsible for 80 percent of carbon dioxide emissions worldwide.
