Question

short note of global warming

Answer 1

Global warming is simply the biggest problem these days. It has a huge side effect on the planet, humanity and our future. In this essay on global warming, we will explain why this is happening and what the effects are. We will add preventative measures that should be implemented as soon as possible.     
Basic notions on global warming
You have probably met this term many times, but you may still not know what it means. Global warming occurs because of the greenhouse effect. In essence, carbon dioxide and similar gases are trapped in the atmosphere. They make the atmosphere thicker and trap the temperature. The temperature is rising, which is defined as global warming. Keep in mind that the entire planet is affected by this effect, even in areas where the temperature is extremely low. 

Answer 2

Global mean surface-temperature change from 1880 to 2017, relative to the 1951–1980 mean. The 1951–1980 mean is 14.19 °C (57.54 °F). The black line is the global annual mean, and the red line is the five-year local regression line. The blue uncertainty bars show a 95% confidence interval.

Global warming is a long-term rise in the average temperature of the Earth's climate system, an aspect of climate change shown by temperature measurements and by multiple effects of the warming. The term commonly refers to the mainly human-caused observed warming since pre-industrial times and its projected continuation, though there were also much earlier periods of global warming. In the modern context the terms are commonly used interchangeably, but global warmingmore specifically relates to worldwide surface temperature increases; while climate change is any regional or global statistically identifiable persistent change in the state of climate which lasts for decades or longer, including warming or cooling. Many of the observed warming changes since the 1950s are unprecedented in the instrumental temperature record, and in historical and paleoclimate proxy records of climate change over thousands to millions of years
