The summers are more warm as the temperature has increased.
Step-by-step explanation:
Global warming is caused by the increase in atmospheric or earth's temperature.
The greenhouse effect has been the major cause of global warming.
We know that the earth's temperature would have been so cold to survive, this problem is solved by greenhouse gases.
As the concentration of gases increase the earth's temperature is also increasing.
This increase in temperature of the planet is causing summers with high temperatures, also due to excessive evaporation rainfall is also lessened. The dry air is evaporating more quickly than precipitation or vice-versa sometimes. The water cycle is disturbed and rainfall is nil or flood is there.
