Will the Summer Be Endless by 2100?

By Natasha Lasky, A new study in the journal Geophysical Research Letters suggests that global warming will drastically alter the seasons, and may cause summers to last at least six months in the Northern Hemisphere by the end of this century.  Meanwhile, winter could last less than two months, with the spring and autumn seasons […]

A Big Blow Up in Hurricane Science

A Big Blow Up in Hurricane Science

by Natasha Lasky, ODP Staff Writer The Atlantic Multidecadal Oscillation, or AMO, was a term coined by climate scientist Dr. Michael Mann to better understand temperature fluctuations of the North Atlantic Ocean. The AMO was thought to be a naturally occurring oscillation of warm and cool phases every 20-40 years and was used by scientists […]

One “Cool” Thing: Minnesota Is Colder Than Siberia


We feel so badly for everyone in Texas suffering through days of bitter cold, many without heat.  But the people at the northern U.S. end of the polar vortex are reeling from the cold as well.  Low-temperature records are being broken in the northern plains — it’s so cold there that even Siberia was warmer.  […]

Snowstorms Shut Down Power, Delay Vaccines Across Southern U.S.

Snowstorms Shut Down Power, Delay Vaccines Across Southern U.S.

After snowstorms swept across the South this week, 14 states are expecting power outages, frozen roads, and dangerous conditions. Hundreds of millions will be impacted by the storm.  Millions will be experiencing rolling blackouts in the coming days due to stress on the Southwest Power Pool (SPP).

Why This Matters: Although it might seem that this polar vortex is an exception to global temperature rise, research says that erratic, far-reaching polar systems like the one we’re seeing now can be directly related to warming temperatures in the Arctic.

Atmospheric Rivers Threaten Once-in-a-Millennium Flooding

In 2020, many Californians prayed for rain as wildfires in the region destroyed millions of acres of land. But they got more than they bargained for when what weather forecasters described as an “atmospheric river” set a course for the state, causing storms that triggered catastrophic mudslides and washed out a section of Highway 1. 

Why This Matters: Atmospheric rivers can carry as much water through the atmosphere as land rivers, and at similar speeds. Between 1978 and 2017, just 10 atmospheric rivers caused over half of all flood damage in the Western U.S.
