NOAA Forecasts Busy Hurricane Season for Atlantic

Less than a year after Hurricane Matthew raked the East Coast, killing 34 people and causing $10 billion in damage in the U.S. alone, coastal areas are once again preparing for the onset of the Atlantic hurricane season. This year, forecasters with the National Oceanic and Atmospheric Administration are expecting to see above-average storm numbers


Days Above 100°F: Projections

Average summer temperature have risen a few degrees across the West and Southern Plains, leading to more days above 100°F in Austin, Dallas and El Paso all the way up to Oklahoma City, Salt Lake City, and Boise. It’s worth noting that this trend has been recorded across the entire Northern Hemisphere, as show in this WXshift animation.

Summer Is Hot, And Getting Hotter

June 1 marked the first day of meteorological summer in the Northern Hemisphere, time for beach trips, barbecues and sweating through summer’s heat. This hottest of all the seasons is getting even hotter as the planet warms from the increase in greenhouse gases in the atmosphere. Meteorological summer differs from astronomical summer, which is


More Hot Days Across the U.S.

Climate change is driving up summer temperatures across the country. We often talk about warming in terms average temperatures, which can be perceived as small to the public, but any rise in the average temperature leads to a rise in the the number of days that are extremely hot.

Arctic Sea Ice

Ice has both ecological and economic benefits and its extent could influence weather around the world.


El Niño

El Niño is a warming of waters in the equatorial Pacific that influences global weather patterns.


Ocean Acidification

Acidifying oceans can hurt coral reefs and shellfish as well as the people that rely on them for their livelihoods.


Carbon Dioxide

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.
