Most of the increase in global temperatures since 1950 has been caused by human activity.

The United States is the second largest contributor to carbon dioxide (CO2) in our atmosphere

As global temperatures increase, our societies will find it harder to adapt to the changes this brings, and some species are more likely to go extinct

NASA data show that average global temperatures in 2019 were 1.8 degrees F (0.98 degrees C) warmer than the 20th century average. In fact, the five warmest years in the 1880–2019 record have all occurred since 2015

Global warming puts coral reefs in danger as the ocean warms, scientist fear that coral reefs will not be able to adapt quickly enough to the resulting changing conditions, and bleaching incidents and diseases will increase
