For the last 400,000 years, CO2 in the atmosphere never topped 300 ppm. Now it’s near 400 ppm.

The increase in greenhouse gases (Carbon dioxide and others) is expected to increase over this century, leading to an increase in average atmospheric and sea surface temperatures. More Carbon dioxide will be absorbed in the oceans making them more acidic, and threatening coral reefs and other sea life. The ocean levels will rise. Coastal zones will be flooded. Weather and climate will change, leading to changes in farming patterns. People in large numbers will be forced to migrate.

It would be possible to reduce emissions by public policies, but politicians are unwilling or unable to negotiate the reforms. In part that is due to the fact that so many deny the scientific evidence. Others I am sure think that they will take immediate benefits from bad policies and be dead before our descendants suffer the consequences.
