Question

Can you please tell me something about water pollution and melting ice? Thank you!

Answer 1

Not only is global warming real, but mankind's activities contributed greatly to our recent warming.

A. Since the turn of the last century, the average global temperature has risen by about 0.8°C (about 1.4°F). Most of this increase has come within the last thirty years. 

B. CO2, methane, water vapor are all greenhouse gases. Over the last ~150 years, the concentration of CO2 has increased by 35%. More greenhouse gases in the atmosphere will means that Earth's surface will become warmer.

C. Most, if not all of this increase in CO2 is the fault of mankind. We know this because of changing ratios of carbon in the atmosphere.

D. Due to increasing concentrations of greenhouse gases in the atmosphere, the average global temperature is expected to rise by another 1.1 to 6.4°C by 2100.[2] The most likely increase will be between 1.7 and 4.4°C.

E. If the world warms by another 1.7°C, then there is a laundry list of bad effects that will most likely come true. That laundry list includes: more evaporation, and heavier precipitation and severe storms. Heavy precipitation often leads to flooding. And because there is heavy precipitation in one area, the next area over will get less precipitation. This is because the storm clouds have already dropped much of the accumulated water vapor. Inland, droughts are expected to worsen. A 1.7°C increase hastens the melting of glaciers and snow pact. Much of the world receives their fresh water from glacier melt. With the glaciers gone, many people will have no drinking water for much of the year... etc. etc....

Haha pollutants from melting glaciers may help explain an increase in ... Alpine glaciers have been melting rapidly since the 1990s, and now scientists think pollution collected in the ice in decades past is flowing ... pollutants in sediment from a model body of water (glacier-fed Lake ... Thank You For Subscribing.
