Climate change

Contemporary climate change includes both global warming and its impacts on Earth's weather patterns. There have been previous periods of climate change, but the current changes are distinctly more rapid and not due to natural causes. Instead, they are caused by the emission of greenhouse gases, mostly carbon dioxide (CO2) and methane. Burning fossil fuels for energy use creates most of these emissions. Certain agricultural practices, industrial processes, and forest loss are additional sources. Greenhouse gases are transparent to sunlight, allowing it through to heat the Earth's surface. When the Earth emits that heat as infrared radiation the gases absorb it, trapping the heat near the Earth's surface. As the planet heats up it causes changes like the loss of sunlight-reflecting snow cover, amplifying global warming. (Source: https://en.wikipedia.org/wiki/Climate_change)

当代气候变化涵盖了全球变暖及其对地球气象模式的影响。尽管历史上曾出现过气候变化，但当前的气候变化显著加速，且并非自然原因所致。相反，这些变化主要由温室气体排放引起，其中以二氧化碳（CO2）和甲烷为主。能源使用过程中燃烧化石燃料产生了大部分这些排放。特定的农业实践、工业流程以及森林破坏也是额外的排放源。温室气体对阳光是透明的，允许其穿透并加热地球表面。当地球以红外辐射形式释放热量时，这些气体吸收了热量，导致热量被困在地球表面附近。随着地球变暖，这引发了诸如反射阳光的雪盖消失等变化，进而加剧了全球变暖。（来源：https://en.wikipedia.org/wiki/Climate_change）
