How has Arizona been affected by climate change?
Arizona’s climate is changing. The state has warmed about two degrees (F) in the last century. Throughout the southwestern United States, heat waves are becoming more common, and snow is melting earlier in spring. As the climate warms, less precipitation falls as snow, and more snow melts during the winter.
Is Arizona getting hotter?
Data from 1970 to 2018 shows that Arizona is the third fastest-warming state in the country. 2020 also brought an end to the warmest decade on record for Phoenix, Flagstaff, Tucson, Yuma and Prescott. The global warming signal isn’t the only factor in our warming temperatures, though.
Why is AZ so hot this year?
The Environment Fuels the Heat The low humidity in Phoenix means there are fewer clouds in the air to shield the land and absorb the heat, and the rocky terrain radiates the heat from the ground. To put it simply, the heat comes at us from all angles, which explains why Phoenix air conditioning is a must!

Was the Earth hotter in the past?
Reconstructed proteins from Precambrian organisms have also provided evidence that the ancient world was much warmer than today. However, other evidence suggests that the period of 2,000 to 3,000 million years ago was generally colder and more glaciated than the last 500 million years.
How many degrees has the Earth warmed in the past 100 years?
Climate Change Over the Past 100 Years. Global surface temperature has been measured since 1880 at a network of ground-based and ocean-based sites. Over the last century, the average surface temperature of the Earth has increased by about 1.0o F.
