Carbon dioxide makes up less than one percent of the Earth’s atmosphere. But the gas is very important to life on Earth. Scientists are finding that processes involving carbon dioxide affect our climate in ways that are difficult to understand. Last month, a committee of the National Academy...
根据第四段第三句和第四句“Some groups that support burningoil and coal want to increase the amount of carbon dioxide in the atmosphere.They oppose international efforts to control carbon dioxide.(一些支持燃烧石油和煤炭的组织希望增加大气中的二氧化碳含量。他们反对国际上控制二氧化碳的努力)”可知,那些...
Presumably fewer clouds will develop in the future over the grass: The increase in carbon dioxide in the atmosphere causes an evaporation decrease of plants. As a result fewer cumulus clouds form, more sunlight reaches the ground - the climate change intensifies. Credit: Bart van Stratum (Phys....
and warmer temperatures would impact the region's infrastructure, economy, human health, and natural resources. Greenhouse gases (GHG) contribute to climate change, and 84% of the United States' GHG emissions are composed of carbon dioxide (CO2), a common emission from motor vehicles and the bu...
Recent findings indicate that the global warming trend that may be caused by increases in atmospheric carbon dioxide may have some beneficial side effects on agriculture. Projected adverse impacts of climatic changes are reviewed. Genetic improvements and soil and water conservation programs can help to...
4 As levels of carbon dioxide - CO2 - in the atmosphere have been rising in recent decades, Earth has been warming. That’s because as a greenhouse gas, CO2 traps heat in Earth’s atmosphere. That warming is one symptom of climate change. And it has the potential to affect food in ma...
I am often asked how carbon dioxide can have an important effect on global climate when its concentration is so small—just 0.041% of Earth's atmosphere. And human activities are responsible for just 32% of that amount.
Carbon dioxide removal (CDR) technologies may be needed to meet climate change targets. A full understanding of public attitudes towards such approaches is currently lacking. Here we report a mixed-methods study on public perceptions of CDR in the United States and the United Kingdom, focusing on...
