In this Climate Science for Everyone article I describe correlation, causation, and two important relationships between them: correlation does not prove causation, but a lack of correlation doesn’t disprove causation either.
Scientists measure the Earth’s temperature three ways – stationary surface thermometers, satellite-based microwave detectors, and balloon-carried thermometers.
Water stores a lot more energy than air does. So when energy stored in the oceans is released back into the atmosphere, the results are dramatic.
Water vapor increases as temperature does, even when the temperature is below freezing. This simple fact is why heavier snowfalls are expected in a warming world.
Climate Science for Everyone: Carbon dioxide increases in the air are mostly from burning coal, oil, and natural gas
Carbon dioxide has been increasing in the atmosphere for a long time now. Scientists have thoroughly examined all the possible sources – the ocean, land plants, and fossil fuels – and concluded that the increase is the result of burning coal, oil, and natural gas.
Scientists can directly measure air that has been sealed in an icy time capsule for 800,000 years. Climate Science for Everyone describes how this works.
In this installment of Climate Science for Everyone – people are adding a lot of carbon dioxide to the atmosphere every year. But how much is “a lot,” really?
