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...
9 Αυγ 2021 · Sound policy and action are based on sound science. As the IPCC’s Summary for Policy Makers underscores, limiting warming to 1.5C can only be achieved through immediate and significantly scaled-up reductions. The only way to reach this goal is through the rapid implementation of more ambitious NDCs.
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. In 2020 global average land temperatures experienced a record high, while 2016 global ocean temperatures remain the highest on record.
• 90% of the extra heat associated with global warming has been taken up by the ocean (see box What are greenhouse gases? on page 6). The ocean is now warming faster than at any time in at least 11,000 years. • Sea level has risen globally by about 20 centimetres (approximately 8 inches) since 1900. It is rising
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.
ocean circulation and SST forcing can be in influencing the global temperature. At the same time, it is clear that greenhouse gas forcings have been important but that shifts in vegeta-tion, and feedbacks in albedo and the carbon cycle from those vegetational shifts can also be important.
