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),...
physics calculates that most of the recent warming stems from heat-trapping greenhouse gases released by the burning of fossil fuels.According toclimate scientist and data analyst Dr. Zeke Hausfather, "Our best estimate is that 100% of the warming the world has experienced is due to human activ...
Methane and nitrous oxide are emitted into the atmosphere in much smaller quantities than CO2, but they still have a significant effect on climate. 甲烷和一氧化二氮被排放到大气中的数量比二氧化碳少得多,但它们仍然对气候有重大影响。 When comparing the different impacts of these gases, we usually ...
