What is happening now?
Global sea levels are rising at an alarmingly fast rate — 17 centimeters (6.7 inches) in the last century alone and going higher. Surface temperatures are setting new heat records about each year. The ice sheets continue to decline, glaciers are in retreat globally, and our oceans are more acidic than ever. We could go on…which is a whole other problem.
What caused this to happen?
The majority of scientists are in agreement that human contributions to the greenhouse effect are the root cause. Essentially, gases in the atmosphere – such as methane and CO2 – trap heat and block it from escaping our planet.
So what happens next?
More droughts and heat waves, which can have devastating effects on the poorest countries and communities. Hurricanes will intensify and occur more frequently. Sea levels could rise up to four feet by 2100 – and that’s a conservative estimate among experts.
