Is global warming happening?
Scientific research has awakened us to the realization that our planet is warming at an unprecedented rate, and human activities are the principal cause. Claims that the observed global warming is not occurring or not related to human activities are false. There is no scientific research that supports that misconception.
Confidence in our answer comes from decades of scientific research — a systematic investigation that acquires new knowledge, validates existing knowledge, or addresses specific questions through rigorous methodologies. Continue reading
Was 2025 an interesting weather year for Wisconsin?
Wisconsin has interesting weather in EVERY year. 2025 started with extreme cold warnings issued for all Wisconsin counties from Jan. 19 to Jan. 21. Wind chill indices were as low as minus 45. The year also ended with cold temperatures and low wind chills at the end of December.
Severe thunderstorms struck southern Wisconsin during the early morning of April 18, with baseball-size hail falling from New Glarus to Edgerton. Continue reading

Why should we care about NCAR?
News that the Office of Management and Budget in the Trump White House will close the National Center for Atmospheric Research, or NCAR, came earlier this month.
NCAR, established in 1960, has provided a unique public/ private partnership in the intervening several decades that has accelerated research and innovation in the weather and climate sciences. It is no exaggeration to say that without NCAR, weather forecasting — where a seven-day forecast made in 2025 is as accurate as a two-day forecast made in 1985 — would not be nearly as advanced as it is today. Continue reading

What is a November gale?
A gale is a sustained wind between 39 mph and 54 mph. Gales are usually caused by large differences in the air pressure between a low pressure system and a strong high pressure system. Gale winds are common in November on the Great Lakes.
This week marks anniversaries of some strong November gales in the Great Lakes region. The most famous of these include the White Hurricane (Nov. 7-10, 1913), the Armistice Day Blizzard (Nov. 11, 1940), the Edmund Fitzgerald Storm (Nov. 9-10, 1975) and the storm Nov. 10-11, 1998. Continue reading
Are the Arctic and Antarctic warming at the same rate?
Global warming is occurring. We know this through scientific observations and our understanding of atmospheric physics and chemistry. We understand that human activities associated with burning fossil fuels is a primary forcing function. While global warming is occurring, observations indicate that rate of warming varies by region.
The Arctic and Antarctic are geographic opposites, and not just because they sit on opposite ends of the globe. The land-sea arrangements are different. Antarctica is a continent surrounded by water; the Arctic is basically a water body surrounded by land. Continue reading
