Climate change involves both global warning triggered by human greenhouse gas emissions and the subsequent changes in weather patterns on a wide scale. Although previous cycles of climate change have existed, human beings had an unparalleled effect on the Earth's climate system since the mid-20th century and have caused change on a glottal scale.We cannot avoid global warning immediately, or even over the next few decades, we can slow down the pace and minimize the amount of global warning by reducing human emissions of heat-absorbing gasses and soot ('black carbon'). Climate change is expected to cause about 250,000 additional deaths per year As global temperatures rise, so does the number of heat stress, heat strokes, and cardiovascular and kidney disease deaths and illnesses. Earth's climate is affected and altered by natural factors such as volcanic eruptions, ocean tides, Earth's orbital shifts, solar variations, and internal variability. It's a short...
