Climate change means more mosquito days, increasing Zika risk.

As the planet continues to warm from the increase in greenhouse gases in the atmosphere, the temperatures that we consider to be normal are also rising.

New Orleans is the 15th hottest city in the U.S.

More than 160,000 people living in Louisiana are especially vulnerable to extreme heat.

Summers are getting muggier as the dewpoint temperature rises

Today, Louisiana averages 35 days a year when heat exceeds dangerous levels. By 2050, the state is projected to average nearly 115 danger days a year.

Louisiana is projected to see one of the nation's largest increases in heat wave days by 2050.

The strong El Niño is not solely responsible for the warming planet. 

Louisiana is projected to see its summer drought threat level more than double by 2050.

Climate Central analysis shows that the number of large fires on Forest Service land is increasing dramatically. 

Louisiana's wildfire threat level is projected to nearly double by 2050.

More than 2 million people living in Louisiana, or 45 percent of the state's population, are living in areas at elevated risk of wildfire.

Currently, Louisiana has 955,000 people at risk of coastal flooding. By 2050, an additional 262,000 people are projected to be at risk due to sea level rise.

2013 study found that surge and flooding from Katrina was anywhere from 15-60 percent higher than it would have been under the climate and sea level conditions around 1900.

Historic carbon emissions have already locked in enough future sea level rise to submerge most of the homes in each of several hundred American towns and cities, according to Climate Central-led research.

Among the lower 48 coastal states, Louisiana currently has the largest area in the 100-year coastal floodplain, approximately 5,500 square miles. By 2050, this is projected to increase to more than 6,900 square miles due to sea level rise.
