A warmer planet doesn’t just raise temperatures. From wildfires to flooding to coral bleaching, here are some real-world implications.
Planet Earth is made up of four overlapping subsystems that contain all of world’s land masses, water sources, living organisms, and gases. These four subsystems are known as spheres. Geographers break down the Earth’s systems into four spheres that make up the world’s air (atmosphere),...
which could affect the radiation balance of the earth's atmosphere. Recent measurements indicate that the atmospheric concentrations of these gases are increasing. Incomplete understanding of the sources, sinks, and/or chemical interactions of these gases in the atmosphere makes it difficult to relate ...
The Earth's climate has been changing since day one. So yes, climate change is real and ongoing. The gases in our atmosphere and the climate conditions that result are NOT stable and are constantly changing over time. Many factors play into this including solar activity, volcanic activity, ...
It is here that the earliest and some of the strongest evidence for an extraterrestrial (something from outside the earth's atmosphere) cause for dinosaur extinction has come. Because the record is more complete in marine rocks, the time units studied are much smaller and more accurate. The ...
We all know CO2 gas emissions are the main cause of global warming. According to the European Commission's Directorate-General for Climate Action (DG CLIMA), the concentration of these gases in the atmosphere is 40% higher than when industrialization began. While CO2 emissions can occur naturally...

"No one has seen that much in the atmosphere from natural processes, ever," Brune said. As a result, the study estimates that somewhere between 2% and 16% of the oxidizing ( 氧化 ),or cleaning that happens naturally in the Earth's atmosphere, is done by lightning....
