INGSA has supported the development of the official Statement by International Senior Scientific Advisers ahead of COP26. The UK Government Office of Science has coordinated the development of a joint statement by 39 senior scientific advisors from every corner of the globe. The science is now unequivocal; now the adoption into policy is the critical point of contention.
We encourage everyone to take a moment to read this statement...

The scientific case for urgent climate action is unequivocal. The IPCC’s Sixth Assessment Report Climate Change 2021: The Physical Science Basis showed there is no doubt human activity has warmed the ocean, atmosphere and land and the world is now 1.09 degrees Celsius warmer than it was in the early industrial era. Sea levels are rising, while weather extremes and their impacts such as heatwaves, excess rainfall, wildfires, flooding and droughts are more intense and more frequent. Climate modelling indicates that with every fractional increase in warming, these effects will get worse with all countries vulnerable.

The latest science tells us it is still possible to limit warming to 1.5 degrees Celsius by the end of the century, but only with steep reduction in global emissions by 2030 and if we reach global net zero around 2050, based on targets defined by Nationally Determined Contributions. Stabilising the climate would limit the increase of sea-level rises and probability of extreme weather events. It would improve prospects for prosperity, and protect the health of humans and natural ecosystems. It will require rapid, urgent and sustained action and significant behavioural, socioeconomic and technological transformations across the world. This must begin with rapid scale up and deployment of a wide range of existing and novel technological solutions.
