Global Change in the Upper Atmosphere, ArtículoThe upper atmosphere is cooling and contracting as a result of rising greenhouse gas concentrations. These changes are likely to affect the orbital lifetimes of satellites.doi:10.1126/science.1135134...
People around the world may feel that the climate has been getting steadily warmer and warmer in recent years. Places which used to be abundant in snowfall have frequently experienced snowfree winters. Drought lasts longer in some dry areas. People find that without air conditioners they could ha...
NASA used the term “climate change” because it more accurately reflects the wide range of changes to the planet caused by increasing amounts of greenhouse gases in the atmosphere. The debate isn’t new. A century ago, chemist Svante Arrhenius started one of the first debates over the potent...
【题文】 Global warming refers to an increase in Earth’s temperature. This change in temperature can cause changes in climate. Climate is the weather condition that occurs in a given place over a period of years. This ___ the average weather conditions, regular change of seasons, and speci...
The detection of anthropogenic changes in the frequency, severity, spatial location, and extent of extreme weather events is consequently important. Extreme Event Attribution (EEA) is a methodological approach that examines the degree to which anthropogenic greenhouse gas emissions had changed the ...
fragile and unique ecosystems and the sentient beings living in such reefs. However, over the long term, climate change will also bring new species into existence and change ecosystems around the world. It is unclear how we should understand our responsibilities in light of such changes (e.g....
Methane concentration in the atmosphere has more than doubled since the pre-industrial era, contributing 20 percent of present-day human-induced global warming. according to Liu Yi, a researcher with the Institute of Atmospheric Physics of the Chinese Academy of Sciences. ...
。根据题干定位到文章第一段第一句Global warming poses a threat to the earth, but humans can probably ease the climate threats brought on by rising levels of carbon dioxide in the atmosphere, global climate specialist Richard Alley told an audience at the University of Vermont(全球气候专家理查德...
So, a decrease in OHT must be due to a weakened ocean circulation. Models agree that ocean circulation changes shape the response to greenhouse gas warming, especially in the North Atlantic12,13. A warmer and wetter atmosphere reduces heat loss from the ocean and enhances freshwater input at ...
the earth would be aboutthirty-three degrees Celsius cooler than it is. So, we need those gases. Theproblem begins when we add huge quantities of extra carbon dioxide into theatmosphere. It means that more heat energy tends to be trap...
