What effects will global warming have on New Orleans?
Increasing temperatures will cause changes in weather patterns and sea level rise for coastal Louisiana. New Orleans is located in a transition zone between wetter climates to the Northeast and drier climates to the Southwest which will create periods of drought and periods of increased precipitation over time.
How did global warming affect Hurricane Katrina?
Climate change contributed to the severity of Katrina’s storm surge, increased Katrina’s rainfall, and may have contributed to the storm’s intensity. Katrina is an iconic example of how the impacts of climate change are disproportionately felt by low-income communities and communities of color.
How are floods linked to global warming?
How is climate change connected to flooding? As climate change warms up the atmosphere, the air can hold 7% more water vapour for every one-degree Celsius rise in temperature. When this air rapidly cools, water vapour turns into droplets which join together to form heavy rainfall4 .
How does global warming affect Louisiana?
Louisiana has been losing about 25 square miles of land per year in recent decades. If temperatures continue to warm, sea level is likely to rise one to three feet during the next century. Rising sea level has the same effect as sinking land, so changing climate is likely to accelerate coastal erosion and land loss.
Will New Orleans be underwater soon?
Louisiana has lost 2,000 square miles of land since the 1930’s, and this is still ongoing. As you are reading this, we are losing land. Therefore, by 2050, New Orleans will most likely be underwater.
Is New Orleans going to sink?
New Orleans, Louisiana is already sinking. The city’s location on a river delta makes it vulnerable to flooding and sea-level rise. A 2016 NASA study found that certain parts of New Orleans are sinking at a rate of 2 inches per year, putting them on track to be underwater by 2100.
What caused Hurricane Katrina?
Katrina formed from the interaction of a tropical wave and the remnants of a previous tropical depression. August 23, 2005 Tropical Depression Twelve formed. The depression became Katrina August 24 when it was located over the Bahamas. Katrina was the 11th tropical storm of the 2005 hurricane season.
When did Hurricane Katrina hit?

How are floods caused What are the effects of floods?
Floods are often caused by heavy rainfall, rapid snowmelt or a storm surge from a tropical cyclone or tsunami in coastal areas. Floods can cause widespread devastation, resulting in loss of life and damages to personal property and critical public health infrastructure.
How does flood affect the environment?
In fact, some ecosystems rely on seasonal flooding to drive ecological processes. Flooding can have a negative effect on wildlife, causing drowning, disease proliferation, and habitat destruction. Unpredictable floods can be harmful even to aquatic life. For example, fish can be displaced and their nests destroyed.
Why New Orleans is sinking?
The sinking was caused entirely by humans who thought they were doing a good thing by pumping water out of the city. The pumps that help New Orleans from filling up with water take sediment out of the ground with the water. Normally, the sediment would continually be replaced by the flooding Mississippi River.
How bad is the heat in New Orleans?
Urban Heat Islands: New Orleans 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. 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.
