Over the past two decades, the United States has suffered from climate change especially the southwest.

Right now, the earth is seeing unprecedented effects from climate change.  There is the increase of heat and drought, wildfires, insect outbreaks, reduced agriculture, and decline of water supply.    This leaves the landscape hot and dry and this is all connected to climate change. The effects have worsened such as more severe storms and droughts, loss of species and more health risks.  

Temperatures were lower on average with more rainfall until the early 2000s climate change started to affect the US more than before.

There are many factors when considering what causes climate change. There are two main contributors to climate change: human and natural causes.  Climate can naturally change over time, but many believe that humans are the main cause of climate change since the 1950s. Greenhouse gasses have increased since the industrial revolution, carbon dioxide, methane and nitrous oxide are now more abundant in the atmosphere. This has increased the greenhouse effect and causes earths surface temperature to rise.  Burning fossil fuels has the biggest human impact on the climate. 

Things such as road construction and deforestation can change the earth’s reflectivity, this can cause slight local warming.When carbon dioxide levels are high its cool when levels are low its warm.
