A large group of scientists meet every five years to look at all the information on climate change. They review the studies and the trends in weather conditions.
Their next report is about to come out. The report says mankind is the culprit. There is a 95 percent chance that humans are the primary cause of climate change.
It repeats most of its earlier findings. “It is extremely likely that human influence on climate caused more than half of the increase in global average surface temperature from 1951 to 2010.” The scientists went on: “This has warmed the ocean, melted snow and ice and raised sea levels.”
Carbon dioxide is the main cause. These are the gases that come out of autos and factories. If the carbon dioxide levels continue to increase, the average global temperature could increase between 2.7 and 5 degrees Fahrenheit.
Increases will lead to widespread melting of ice, extreme heat waves, food shortages and big changes in plant and animal life.
The report is about global conditions. Changes in local weather patterns are harder to predict. The group says that, if world governments get gas emissions under control, they could limit global warming.
If not, sea levels might rise by 2 feet or more by 2100. The largest rise would endanger New York, London, Shanghai, Venice, Miami and New Orleans.
The remaining skeptics about climate change should remember that working on the problem would improve the planet. Ignoring it might be inviting global disaster.
