Hurricane Watch Checklist: Four Factors that Strengthen and Four that Weaken Tropical Cyclones

Whenever I see that a tropical storm is threatening to convert into a tropical cyclone – that’s meteorology-speak for hurricanes in the Atlantic, typhoons in the Pacific or cyclones in the Indian Ocean – I consult my checklist.  These are the factors that can nip that tropical storm in the bud or escalate it into a full blown hurricane.

Where is Sea Level Rise Most Rapid? Today Congress Heard the Answer: North America

Today members of the U.S. Senate Committee on Environment and Public Works (EPW) were presented with a figure illustrating that the Gulf Coast and U.S. East Coast experienced the fastest pace of sea level rise compared to nearly all the rest of the coasts around the world from 1955 to 2003. I was struck by the vigorous discussion around the graphs, which were presented by my colleague Dr. James McCarthy and others before a full committee hearing entitled “Update on the Latest Climate Change Science and Local Adaptation Measures.”

Drought Double Whammy: As the World Warms, U.S. Droughts Likely to Be Hotter, More Damaging

The drought ravaging U.S. corn crops this summer may remind some of the horrific Texas region droughts of the 1950s. Yet scientists studying those droughts found that today’s droughts in the region are more likely to be much hotter. This double whammy of drought combined with higher temperatures can turbo charge evaporation rates, which dries out soils even more and wreaks havoc with crops and livestock that can suffer immensely in the scorching heat without irrigation or other mitigation efforts.

Evidence Check: Which Extreme Weather Events Are More Linked with Climate Change – Heat Waves or Hurricanes?

The heat gripping the United States this month has been relentless. And if that weren’t enough, hurricane season is upon us. How does the scientific evidence stack up over the past decades regarding how these extreme events are changing? And how much influence does human-caused climate change have on these events? We created an infographic to serve as a quick reference of the current state of scientific understanding.

Beware: Wildfire Smoke Can Be Like Smoking a Couple of Packs of Cigarettes over a Few Hours

This week I heard from a friend who evacuated from their work place and another whose parents had to evacuate from their home to protect themselves from wildfires raging throughout the West. Yet, the media coverage I have seen often focuses on the risks to and loss of property.  Coverage has been much less focused on the risks to the health of people both in close proximity to fires and those not in the immediate paths of fire, but who still can suffer from its more widespread effects.  Read More
