Can We Connect Extreme Flooding to Climate Change?

I was in downtown Cedar Rapids on Tuesday to witness the city's second-largest crest of the Cedar River in recorded history. Pretty amazing since a "thousand year" flood inundated a majority of this city of 130,000 people only eight years ago. But back then there was little/no mitigation effort. According to ABC News, $10 billion damage occurred.

California is nearing its peak risk period for catastrophic wildfires. Abundant fuel covers the state from lack of rain and post summer heat. October has historically been the month with the deadliest, most destructive and largest wildfires, according to Cal Fire. The term “fire season” is almost obsolete for the state. In fact, Southern


Climate Change and Fall Foliage

With the end of September fast approaching, many people across the U.S. are eagerly watching the trees for their annual display of brilliantly colored fall foliage.

Sneaky Drought Continues for the Eastern U.S.

Three months ago, only 8 percent of the Northeast was in a moderate drought. That number has swelled to

CO2 is a potent greenhouse gas and plays a vital role in regulating Earth's surface temperature through radiative forcing and the greenhouse effect


Extreme Heat

Increasing frequency and magnitude of extreme heat can affect health, power usage and more.


Snow Cover

A shorter snow season increases the amount of sunlight absorbed by the Earth’s surface and can further warm the planet.


Sea Level Rise

Sea level rise could force millions to leave coastal areas and cost the world trillions of dollars.


Land Ice

Melting land ice contributes to sea level rise.


U.S. Wildfires

Wildfires damage forests and release CO2.
