根据第一段“The last time CO2 levels were as high as today, ocean waters drowned the lands where big cities like Houston, Miami, and New York City now exist.(上次二氧化碳浓度达到今天的水平时,海水淹没了休斯敦、迈阿密和纽约等大城市现在所在的土地。)”以及第二段“It’s a time called the ...
This paper presents empirical evidence for the effect of rising atmospheric CO2 levels on the Earth's surface energy balance. The increase in surface radiative forcing between the years 2000 and 2010 measured at two experimental sites is directly attributable to the 22 parts per million increase in...
a variety of health effects. These may include headaches, dizziness, restlessness, a tingling or pins or needles feeling, difficulty breathing, sweating, tiredness, increased heart rate, elevated blood pressure, coma, asphyxia to convulsions and even frostbite if exposed to dry ice. The levels ...
Effects of high CO2 levels on surface temperature and atmospheric oxidation state of the early Earth. One-dimensional radiative-convective and photochemical models are used to examine the effects of enhanced CO 2 concentrations on the surface temperature o... JF Kasting,JB Pollack,D Crisp - 《Jou...
ulterior statistical analysis. The extension of the hexagons can been chosen among 21 levels (called “resolution”, see Supplementary Table1), ranging from millions of square kilometers (level 0) to hundreds of square meters (level 20). As for quadrat analysis, the selection of the extension...
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 many ways. ...
Using ice cores drilled in Greenland and Antarctica, scientists havea pretty good recordof how the composition of Earth’s atmosphere has fluctuated over the last 800,000 years. That’s why scientists know carbon dioxide levels are higher than they’ve ever been in that amount of time. ...
UK researchers have identified a biological mechanism that could explain how the Earth's atmospheric carbon dioxide and climate were stabilised over the past 24 million years. When CO2 levels became too low for plants to grow properly, forests appear to have kept the climate in check by slowing...
