How does climate change?

Answer 1

Climate is an average of weather over several years, at least twenty or thirty.

Climate is always changing, but changes in the past have happened very slowly, over thousands of years.

Humans have never been able to change the climate before, but now, since we began burning fossil fuels, we have added so much greenhouse gases to the atmosphere that the world is warming up. This global warming is causing climate change, because heat is energy, and the extra energy in the oceans and atmosphere is changing our weather substantially. Over the years the climate changes.

Answer 2

Climate change is primarily caused by the increase of greenhouse gases in the atmosphere, which trap heat and lead to rising global temperatures. Human activities, such as burning fossil fuels and deforestation, are major contributors to this increase in greenhouse gases. The impacts of climate change include rising sea levels, more frequent and severe weather events, and shifts in ecosystems and habitats.
