Ocean Sound Propagation in a Changing Climate: Global Sound Speed Changes and Identification of Acoustic Hotspots. RESEARCH ARTICLE. 10.1029/2021EF002099. Key Points: New data set of global sound speed at the end of XXI century with associated uncertainty: global sound speed generally increases.
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...
• 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.
22 Ιουν 2023 · To address the global noise pollution challenge, scientists should investigate the ecosystem-level effects of noise and the interactions between noise pollution and other global change factors such as chemical pollution and climate change.
• 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
Sometimes a combination of observations and models can be used to test planetary-scale hypotheses. For example, the global cooling and drying of the atmosphere observed after the eruption of Mt. Pinatubo (Section 8.6) provided key tests of particular aspects of global climate models (Hansen et al., 1992).
