Explanation:
Detailed explanation-1: -As greenhouse gas emissions from human activities increase, they build up in the atmosphere and warm the climate, leading to many other changes around the world-in the atmosphere, on land, and in the oceans.
Detailed explanation-2: -However, beginning in the late 1700s, the net global effect of human activities has been a continual increase in greenhouse gas concentrations. This change in concentrations causes warming and is affecting various aspects of climate, including surface air and ocean temperatures, precipitation, and sea levels.
Detailed explanation-3: -Carbon dioxide from the burning of fossil fuels is the largest single source of greenhouse gas emissions from human activities.
