Of course, global warming makes the world a lot hotter... but exactly how much hotter? Global temperatures have risen 1.62 F (0.9 C) since the late 1900s. Additionally, 2016-2020 have been the 4 hottest years in recorded history, and most months in 2016, which is the hottest so far, hold the monthly temperature records as well. This is bad, because our Earth can't take much more heating before the damage is irreversible.
Oceans absorb most of that heat that enters the lower atmosphere, which has led to an increase in its temperatures as well - creating many adverse effects. This is leading to the melting of polar ice caps (286 billion/yr in Greenland & 127 billion/yr in Antarctica), as well as the disappearance of snowcaps and glaciers everywhere. Marine life, such as coral and fish, can only survive in the oceans at a very specific temperature, and as the sea keeps heating up, this life contintues to die.
Sea levels are constantly rising, and in the past century it has risen 8 inches. However, in the past 2 decades levels have risen 16-21 inches! That's over twice the amount in 1/5th of the time! This rate is only increasing, and studies show that it will have risen an additional 1-8 feet by 2100!
Weather patterns of events like storms and heat waves will change drastically, and become more prominent. Hurricanes will gain intensity and frequency, and research shows that the amount of Category 4 and 5 hurricanes has been increasing since the late 1980s. Heat waves and droughts will also become more common, but flooding and precipitation will also gain strength. Overall, weather systems will become even more chaotic than ever before - a trend already starting to appear.
