Question

The average temperature on the Earth has increased in the past few years. Why?

Answer 1

hey mate here is your answer

due to global warming

Global warming, also referred to as climate change, is the observed century-scale rise in the average temperature of the Earth's climate systemand its related effects. Multiple lines of scientific evidence show that the climate system is warming.[2][3][4] Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record, and in paleoclimate proxy records of climate change over thousands to millions of years.[5]

In 2013, the Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Reportconcluded, "It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century."[6]The largest human influence has been the emission of greenhouse gases such as carbon dioxide, methane, and nitrous oxide. In view of the dominant role of human activity in causing it, the phenomenon is sometimes called "anthropogenicglobal warming" or "anthropogenic climate change". Climate model projections summarized in the report indicated that during the 21st century, the global surface temperature is likely to rise a further 0.3 to 1.7 °C (0.5 to 3.1 °F) to 2.6 to 4.8 °C (4.7 to 8.6 °F) depending on the rate of greenhouse gas emissions.[7] These findings have been recognized by the national science academies of the major industrialized nations[8][a] and are not disputed by any scientific body of national or international standing.[10][11]
