How Exactly Does Carbon Dioxide Cause Global Warming?
2021年2月25日 · Over the past few years, we’ve received a lot of questions about carbon dioxide — how it traps heat, how it can have such a big effect if it only makes up a tiny percentage of the atmosphere, and more.
More Carbon Emissions Will Kill More People. Here’s How Many.
2021年7月29日 · The addition of 4,434 metric tons of carbon dioxide emissions beyond the baseline 2020 rate is expected to cause one human death by 2100. Here, lower bars indicate individuals in each country would have higher impact; those 4,434 tons are equivalent to the lifetime emissions of just 3.5 Americans, as opposed to 15.6 Mexicans or 146.2 Nigerians.
You Asked: If CO2 Is Only 0.04% of the Atmosphere, How Does it …
2019年7月30日 · For more information on how carbon dioxide traps heat, why water vapor isn’t the culprit, and answers to several other interesting questions, check out this post: How Exactly Does Carbon Dioxide Cause Global Warming?
How Climate Change Will Affect Plants – State of the Planet
2022年1月27日 · Plants use sunlight, carbon dioxide from the atmosphere, and water for photosynthesis to produce oxygen and carbohydrates that plants use for energy and growth. Rising levels of CO2 in the atmosphere drive an increase in plant photosynthesis—an effect known as the carbon fertilization effect.
What Is Ocean Acidification & Why Does It Matter?
2015年12月9日 · Excess carbon dioxide absorbed into the oceans is starting to have profound effects on marine life, from oysters to tiny snails at the base of the food chain. Our scientists explain the changes and what they are learning about ocean acidification in the past.
Plankton Are Central to Life on Earth. How Is Climate Change …
2023年8月23日 · When they perform photosynthesis, they take carbon out of the atmosphere; but when they eat other organisms, they end up emitting more CO2 than they absorb. Climate change may also be increasing the frequency of large phytoplankton blooms in …
The Damaging Effects of Black Carbon – State of the Planet
2016年3月22日 · The deaths are mainly caused by the inhalation of particulate matter, especially black carbon. But black carbon not only has impacts on human health, it also affects visibility, harms ecosystems, reduces agricultural productivity and exacerbates global warming.
Can Soil Help Combat Climate Change? – State of the Planet
2018年2月21日 · Because microbial decomposition releases carbon dioxide, the soil can store more carbon when it is protected from microbial activity. One key way that happens is through the formation of soil aggregates. This occurs when tiny particles of soil clump together, sheltering carbon particles inside them.
Why Thawing Permafrost Matters – State of the Planet
2018年1月11日 · A 2017 study estimated that if global temperatures rise 1.5˚C above 1861 levels, thawing permafrost could release 68 to 508 gigatons of carbon. Without factoring in human activity, this carbon alone would increase global temperatures 0.13 to1.69˚C by 2300.
Ocean Uptake of CO2 Could Drop as We Cut Carbon Emissions
2020年6月3日 · Volcanic eruptions and human-caused changes to the atmosphere strongly influence the rate at which the ocean absorbs carbon dioxide, says a new study. The ocean is so sensitive to changes such as declining greenhouse gas emissions that it immediately responds by taking up less carbon dioxide.
