It also changes seawater chemistry, and has been shown to harm organisms ranging from oysters to se a urchins.CO2 in the atmosphere today averages 385 parts per million (ppm). By mid-century, the concentration could easily be more than 550 ppm, which would decrcase the rate at which ...
DB: This is Earth and Sky. When we burn fossil fuels, we send carbon dioxide -- or CO2 -- into the air. Most scientists think this CO2 contributes to global warming. In the past 20 years, levels of CO2 in the atmosphere haven't risen as much as...

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.” “...
athe increase in CO2 levels in the atmosphere as a result of human activity means that the world is already locked into some climate change, and faces a major challenge to keep global temperature rises to below two degrees. 在二氧化碳水平的增量在大气由于人类活动意味着世界已经是锁着的入一些气候...
aToday,you do others donot want to do.tomorrow,you will do others cannot do. 今天,您做其他donot想要do.tomorrow,您将做其他不可能做。[translate] aThe atmosphere is composed of N2 (78%), O2 (21%), CO2, H2O, CO, SO2, etc. Since different chemical element has a different spectral prope...
Levels of carbon dioxide in the atmosphere have grown 35 per cent more quickly than expected since 2000 because of inefficiency in fossil fuel use and the weakening of natural "carbon sinks", scientists warned today.The Birmingham Post (England)...
Climate change is undoubtedly one of the most pressing issues facing our planet today. As a result of human activities, particularly the excessive release of carbon dioxide (CO2) into the atmosphere, global temperatures have been rising at an alarmingrate. To mitigate this crisis, it is imperativ...
Here we present a 135-kyr record of shallow subsurface pCO2 and nutrient levels from the Norwegian Sea, an area of intense CO2 uptake from the atmosphere today. Our results suggest that the Norwegian Sea probably acted as a CO2 source towards the end of Heinrich stadials HS1, HS4 and HS11...
CO2 emissions have become a major concern in today's world. The excessive release of carbon dioxide into the atmosphere has led to numerous environmental issues, such as global warming and climate change. In this essay, I will discuss the causes of CO2emissions and their impact on the environm...
