"The five warmest years over the last century occurred in the last eight years"

This quote by James Hansen recommends that the Earth is getting warmer. The five warmest years over the last century have all took place in the last eight years, which is a clear sign that the Earth's climate is altering. This is likely due to human activities such as burning nonrenewable fuel sources, which release greenhouse gases into the environment. These gases trap heat and trigger the Earth's temperature to rise. This quote is a stark tip that we need to do something about it to reduce our emissions and protect our world from more warming. We should also work to adapt to the changes that have currently taken place, such as increasing sea levels and more severe weather occasions. If we do not take action now, the consequences of climate change will just become more serious.
