Senior science advisers and presidents of national science academies from more than 20 countries have signed a statement to leaders of world governments reiterating the existing scientific consensus and the need for immediate action to tackle climate change. The signatories call on world leaders to develop âambitiousâ long-term strategies based on solid scientific evidence that can keep the Paris agreement target of limiting global warming to 1.5 Â° C within reach.
“There is no doubt that human activity has warmed the ocean, the atmosphere and the land and the world is now 1.09 Â° C warmer than it was at the start of the industrial age.” , reads the letter, whose signatories include UK government science adviser Patrick Vallance, White Eric Lander, director of the House Office of Science and Technology Policy, and Krishnaswamy VijayRaghavan, India’s senior science adviser. “Climate modeling indicates that with each fractional increase in warming, these effects will worsen with all vulnerable countries.”
The statement, written ahead of the Cop26 climate summit in Glasgow, also urges governments around the world to increase international collaboration to accelerate research, development, demonstration and deployment of effective mitigation and adaptation solutions. to global warming.
Science advisers warn there is an “urgent need” for improved methods of creating, storing and using low-emission energy – including improved semiconductors, batteries and low-emission fuels – as well as work on heating and cooling, and carbon capture and capture. storage room. In addition, they suggest that more efficient, innovative and environmentally friendly strategies for agriculture, industry and transport are also needed.
“Further work is needed to improve our understanding of the interactions between biodiversity, ecosystems and climate change, to protect the natural world from further loss of biodiversity and to maximize its capacity to store carbon,” the statement concluded.
