Detailed explanation-1: -A rise of 3°C in global temperatures above pre-industrial levels by 2100 would be disastrous. Its effects would be felt differently around the world, but nowhere would be immune. Prolonged heatwaves, droughts and extreme weather events could all become increasingly common and severe.

Detailed explanation-2: -In a 3-degrees-warmer world, the coastlines of today will largely be gone, endlessly reduced over the coming centuries by rising seas. By the end of 2100, sea levels are expected to rise by about 2 feet on average. That would be near catastrophic for small island nations.

Detailed explanation-3: -Greenhouse Gases Carbon dioxide, methane, and nitrous oxide concentrations are now more abundant in the earth’s atmosphere than any time in the last 800, 000 years. These greenhouse gas emissions have increased the greenhouse effect and caused the earth’s surface temperature to rise.
