解析:A.人类二氧化碳排放量的增加B.全球变暖的恶化C.世界森林的消失D.海洋生物减少.文中第一段可知The rise in human emissions of carbon dioxide is driving dangerous changes in the chemistry and ecosystems of the world's oceans, international marine(海洋的)scientists have warned.国际海洋(International Ma...
CO2 released by humans and livestock through digestion and decomposition is an important part of the urban carbon cycle, but is rarely considered in studies of city carbon budgets since its annual magnitude is usually much lower than that of fossil fuel emissions within the boundaries of cities. ...
aThe ocean absorbs about a quarter of human-caused emissions of CO2 annually, and, over the last 250 years, the oceans have absorbed 560 billion tons of CO2. 海洋年年吸收二氧化碳四分之一人导致的放射,并且,在过去250年期间,海洋吸收了560十亿吨二氧化碳。[translate]...
When it comes to removing human-caused emissions (排放) of the greenhouse gas-carbon dioxide from Earth's atmosphere,trees are a big help. Through photosynthesis(光合作用), trees pull the gas out of the air to help their leaves, branches and roots grow. Forest soils can also sequester(使隔...
due to human influence on the climate. Simulated emissions from the 2023 wildfire season were eight times their 1985-2022 mean. With continued warming, the likelihood of extreme fire seasons is projected to increase further in the future, driving additional impacts on health, society, and ...
China launched a national carbon market in July 2021, and had seen a cumulative turnover of 195 million tonnes of carbon emission quotas worth nearly 8.6 billion yuan (about 1.2 billion U.S. dollars) by Sept. 14. The country pledged to peak CO2 emissions by 2030 and achieve carbon neutrali...
activities.Another indication that human emissions surpass those of volcanoes is the fact that atmospheric CO2 levels, as measured by sampling stations around the world, have gone up consistently year after year regardless of whether or not there have been major volcanic eruptions in specific years....
Figure 1:CO2levels (Green Line -Law Dome, East Antarcticaand Blue line -Mauna Loa, Hawaii) and CumulativeCO2emissions in gigatonnes ofCO2(Red Line -CDIAC). Confirmation that risingcarbon dioxidelevels are due to human activity comes from analysing the types of carbon found in the air. The ca...
He says that Carney’s basic argument is that climate change is an existential urgency and we must “achieve net zero carbon emissions as quickly as possible, failing which all human life will be in danger.” How do we do this? The Covid lockdown’s show us how we can achieve the sal...
Cities and other human settlements are major contributors to climate change and are highly vulnerable to its impacts. They are also uniquely positioned to reduce greenhouse gas emissions and lead adaptation efforts. These compound challenges and opportun
