Key Points: New data set of global sound speed at the end of XXI century with associated uncertainty: global sound speed generally increases. Climate-induced sound speed variations are substantial in selected “acoustic hotspots”
28 Ιαν 2019 · All this highlights the need for much stronger links between ecosystem scientists, social scientists studying human adaptation and resilience, and those designing and implementing climate change...
Global average temperature was 0.98°C (1.76 °F) higher in 2020 than in the late 1800s.15. The warmest year on record since records began in 1880 was 2016, with 2020 ranking second.

24 Αυγ 2020 · Abstract. Our climate is changing due to anthropogenic emissions of greenhouse gases from the production and use of fossil fuels. Present atmospheric levels of CO 2 were last seen 3 million years ago, when planetary temperature sustained high Arctic camels.
It explains how scientiûc and policy debates work, outlines the scientiûc evidence for the reality and seriousness of climate change and the basic atmospheric science that supports it, and discusses policy options and the current state of the policy debate.
Introduction. Changes in climate have significant implications for present lives, for future generations and for ecosystems on which humanity depends. Consequently, climate change has been and continues to be the subject of intensive scientific research and public debate.
