Restart climate measures

Greenhouse gas concentrations are at record levels, leading to future temperature increases. The emissions gap between aspiration and reality remains high. Under current policies, there is a two-thirds chance of global warming of 3°C this century, reports United in Science.

United in Science offers a much-needed basis for hope. It explores how advances in the natural and social sciences, new technologies and innovations are improving our understanding of the Earth system and could be game-changers for climate change adaptation, disaster risk reduction and sustainable development.

"We now need urgent and ambitious action to support sustainable development, climate action and disaster risk reduction. The decisions we make today can be the difference between future collapse or a breakthrough to a better world," said WMO Secretary-General Celeste Saulo.

“Artificial intelligence and machine learning have emerged as potentially transformative technologies that are revolutionizing weather forecasting and can make it faster, cheaper and more accessible. State-of-the-art satellite technologies and virtual realities that bridge the physical and digital world are opening new frontiers, for example in land and water management," said Celeste Saulo.
