Temperatures directly correlate to CO2 levels In Antarctica, but not in the tropics or Northern Hemisphere. Here's why:
Used coffee grounds can be recycled to make air filters that remove methane, a powerful greenhouse gas, from the atmosphere.
Since the beginning of human civilization, Earth has lost half its trees.
Bacteria release gasses that build up inside the body, causing it to float.
Scientists have a developed a solar-energy-based technology to remove carbon dioxide from the atmosphere. But is it a feasible solution to global warming?
Sewage treatment plants and landfills both release a lot of greenhouse gases in the process of decomposing waste.
It's a gas! Air consists of nitrogen and oxygen and lots of empty space.
Scientists are engineering a method for turning solar energy into fuel.
Birds and many reptiles evolved a specialized way of breathing—one-way air flow.
Global warming has created a feedback loop, wherein Arctic sunlight converts thawing ice into more CO2.
