But today, carbon dioxide levels are skyrocketing as humans burn long-buried fossil fuels. “CO2 in the atmosphere has gone up 100 ppm in my lifetime,” said Kathleen Benison. a geologist at West Virginia University who researches past climates. “That’s incredibly fast geologically.” “...
The remains of land plants can be used to calculate the amount of CO2 in Earth's atmosphere. Credit: A. Hope Jahren. A common message in use to convey the seriousness of climate change to the public is: "Carbon dioxide levels are higher today than they have been for the past one milli...
a leap from the one-hour tests and its inner temperature should be controlled stably. Moxie has proved to endure the extreme conditions on Mars, however, and the team plans to assess the machine’s limits in the coming months when atmosphere is thick and carbon dioxide levels are high. They...
According to the US Geological Survey (USGS), the world's volcanoes, both on land and undersea, generate about 200 million tons of carbon dioxide (CO2) annually, while our automotive and industrial activities cause some 24 billion tons of CO2 emissions every year worldwide. Des...
英语翻译 Today's society is a highly developed technological society.However,the shortcomings in the development process are obvious,such as:carbon dioxide,and environmental pollution.But the most serious should be the carbon dioxide problem. Now the problem of global warming because of excess emission...
or climates at least significantly warmer than now. It’s happening fast. When CO2naturally increases in the atmosphere, pockets of ancient air preserved in ice show this CO2rise happens gradually, over thousands of years. But today, carbon dioxide levels are skyrocketing as humans burn long-buri...
With more and more advanced seismic wave imaging technology, scientists are studying the operation of the huge machine of the earth. But another scientific revolution may take half a century.4, how hot will the earths gre 7、enhouse become?Although carbon dioxide levels in the atmosphere are ...
Temperature, carbon dioxide levels rise, increasing or decreasing rainfall and other climate changes are affecting agricultural production 翻译结果2复制译文编辑译文朗读译文返回顶部 Climate change is one of today's international research hot spots. Increase in temperature, carbon dioxide concentrations rise,...
Global warming is one of the major environmental problems we are facing today. Scientists think a further rise in the carbon dioxide levels will make this situation worse. The greenhouse effect causes the earth’s heat to be trapped in the atmosphere, which results in the increase in temperature...
Carbon Dioxide Reuse and Sequestration: The State of the Art Today Sally Benson (LBNL), Thomas Dorchak (NETL), Gary Jacobs (ORNL), James Ekmann (NETL), Jim Bishop (LBNL), and Thomas Grahame (DOE) Abstract Atmospheric concentrations of CO 2 and other greenhouse gases (GHGs) are growing st...
