Global warming: nations urged to review their climate plans

New York: In less than two weeks, the UN Climate Change Conference COP27 will take place in Sharm el-Sheikh, Egypt, and Simon Stiell, Executive Secretary of UN Climate Change, has called on governments to review their climate plans and to strengthen them to close the gap between where emissions are heading and where science indicates they should be this decade.

“COP27 is the moment when world leaders can regain momentum on climate change, make the necessary pivot from negotiations to implementation and move forward with the massive transformation that needs to take place in all sectors of society to address the climate emergency,” he said.

Stiell urged national governments to show at the conference how they will implement the Paris Agreement through legislation, policies and programs, as well as how they will cooperate and provide support for implementation.

4 priority areas

He also called on nations to make progress in four priority areas: mitigation, adaptation, loss and damage, and finance.

While plans submitted by most Paris Agreement signatories would reduce global greenhouse gas emissions, they are still not ambitious enough to limit global temperature rise to 1.5 degrees Celsius d end of the century, warns a new UN Climate Change (UNFCCC) report. Wednesday.

The current combined National Determined Contributions (NDCs) “meaning countries’ national efforts to address emissions and mitigate climate change” are leading our planet to warming by at least 2.5 degrees, a level deemed catastrophic by scientists from the Intergovernmental Panel on Climate Change (IPCC).

Reduction of CO2 emissions

In 2019, the IPCC reported that to curb global warming, CO2 emissions needed to be reduced by 43% by 2030, compared to 2010 levels, but current climate plans instead indicate a 10.6% increase. .

However, this is an improvement on last year’s report, which showed a 13.7% increase by 2030 and a continued increase in emissions after 2030.

“The downward trend in emissions expected by 2030 shows that nations have made progress this year,” said Simon Stiell, executive secretary of UN Climate Change.

“But the science is clear, and so are our climate goals under the Paris Agreement. 1.5 degrees Celsius,” he warned.

Stiell stressed that national governments must strengthen their climate action plans now and implement them over the next eight years.

COP26 Glasgow

Last year, at the UN Climate Change Conference COP26 in Glasgow, Scotland, all countries agreed to review and strengthen their climate plans, however, only 24 out of 193 countries submitted updated plans. day at the United Nations.

“…This is disappointing. Government decisions and actions must reflect the level of urgency, the seriousness of the threats we face and the short time we have left to avoid the devastating consequences of the runaway climate change,” the UN said. Head of Climate Change.

The good news is that most of the nations that have submitted a new plan have strengthened their commitments, showing more ambition in the fight against climate change, according to the agency, which called the fact a “ray of hope”. .

More positive trends were found in a second United Nations climate change assessment released on Wednesday examining long-term net zero strategies.

62 countries, representing 93% of the world’s GDP, 47% of the world’s population and approximately 69% of total energy consumption, have implemented these plans.

“This is a strong signal that the world is starting to aim for net zero emissions,” the agency said.

Still, experts note that many net zero goals remain uncertain and postpone critical actions that need to take place now.
