Question

explain gobal warming​

Answer 1

Global mean surface-temperature change from 1880 to 2018, 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.In the modern context the terms global warming and climate change are commonly used interchangeably, but climate change includes both global warming and its effects, such as changes to precipitation and impacts that differ by region.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. due to increase of CFC means chlorofluorocarbon uses of modern technology like fridge air conditioner heater and various machines in which the toxic chemical are present and while using that they release carbon mono oxide and chlorofluorocarbon and various toxic chemical in the air which harms the environment

Answer 2

Answer:

Global warming is the ongoing rise of the average temperature of the Earth's climate system and has been demonstrated by direct temperature measurements and by measurements of various effects of the warming.
