Glasgow: More than 200 scientists told the COP26 summit on Thursday to take immediate action to stop global warming, warnings in open letters that some of the effects of climate change “cannot be restored” for generations.
The main task of the Glasgow meeting is to implement the Paris Agreement, with the aim of limiting temperature increases to between 1.5 and 2 degrees Celsius above the pre-industrial level.
But as negotiations entering their last days, commitments made so far can still cause 2.7C “big disaster” warming in 2100, according to the United Nations.
“We, climate scientists, emphasize that direct, strong, fast, sustainable, and large-scale actions are needed,” to continue to warm in Paris’s target, the letter said, signed by researchers around the world.
In August, a bomb “red code” report from the world’s climate science body, the intergovernmental panel about climate change (IPCC), warned that the average temperature of the Earth would reach a 1.5c threshold around 2030, a decade earlier than that Projected only three years ago.
To surpass overshooting that the temperature of the IPCC target said emissions must go down 45 percent this decade.
Open letter Thursday, signed by several IPCC report authors, calls on the delegation in Glasgow to “fully recognize” scientific evidence they have compiled from severe threats caused by climate change.
“COP26 is a historic moment for the fate of the climate, society, and ecosystem, because human activities have warmed up the planet with around 1.1C and future greenhouse gas emissions will determine additional warming in the future,” the letters said.
The heating atmosphere has expanded extreme weather, lowering communities around the world for fires and more intense droughts, severe displacement and economic difficulties.
And emissions still increase.
The main rating recently showed global CO2 emissions set to rebound in 2021 to the pre-pandemic level.
“Cumulative greenhouse gas emissions have so far been doing our planet to change the key to the climate system that affects the human and sea ecosystems and land, some of which cannot be changed for future generations,” said the letter.
