Climate change is driving a notable increase in the frequency and intensity of extreme weather events across the globe.This trend is linked to human activities, particularly the burning of fossil fuels, which has led to a significant rise in greenhouse gases in the atmosphere.
One of the most direct impacts of climate change is the increase in global temperatures.Since 1880, the average global temperature has risen by approximately 1.9 degrees Fahrenheit, contributing to more intense and prolonged heatwaves.

Increased Flooding and Rainfall
Flooding events are becoming more frequent and severe due to climate change.The Fourth National Climate Assessment indicates that heavy rainfall events have increased in both frequency and intensity, leading to more severe flooding.

lung.orgWarmer air holds more moisture, which results in denser clouds and heavier rainfall.

lung.orgIn the US, nine of the top ten years for extreme one-day precipitation have occurred since 1995, and projections suggest that extreme rainfall events could become three times more likely and up to 20 percent more severe within the next 45 years.

The link between climate change and the increase in wildfires is well-established.Rising temperatures and changing precipitation patterns create ideal conditions for wildfires to ignite and spread.

Health Impacts of Extreme Weather
The health implications of extreme weather events are profound.Flooding can lead to mold growth, which exacerbates respiratory issues such as asthma.

earthjustice.orgThe smoke from wildfires can lead to respiratory diseases and cardiovascular issues, highlighting the interconnectedness of climate change and public health.
The economic burden of extreme weather events is significant and growing.Flooding, in particular, has systemic economic impacts that reverberate throughout communities.
