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.
12 Μαΐ 2022 · As measured by the Lamb wave amplitudes, the climactic Hunga explosion was comparable in size to that of the 1883 Krakatau eruption. The Hunga eruption produced remarkable globally detected infrasound (0.01 to 20 hertz), long-range (~10,000 kilometers) audible sound, and ionospheric perturbations.
• 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
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.
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.
