Climate Change Increasing Frequency of Coastal Flooding

“King Tides,” the highest astronomical tides of the year, are just around the corner — as the Earth, moon, and sun line up for peak gravitational pull on the oceans. Ocean currents and topography also play a role in when these peaks occur and how high they get. On the East and Gulf Coasts, they tend to come in October, while on the West Coast, they

Strongest Tropical Cyclones by Region

Tropical cyclones, the more general term for hurricanes globally, have been setting records in the last few years. In a warming climate, the most intense of these storms are getting stronger, and some of the strongest on record have been seen in the last decade. Defined by wind speed, last year’s Hurricane Irma was the strongest storm on record in

More Extreme Rain: Climate Extremes Index

This summer has brought flooding rainfall to several parts of the U.S. Pennsylvania had its wettest summer on record, and the neighboring states of Maryland, Virginia, and West Virginia each had one of their 10 wettest summers on record. The warming climate enhances the water cycle, leading to more extreme rainfall. The NCEI Climate Extremes Index

Fall Warming Trends Across the U.S.

Happy meteorological fall! This week, we examined the trends in average fall temperature across the U.S. Of the 244 cities analyzed, 80 percent have warmed at least 1°F in the last half-century, compared to only 1 percent which have cooled 1°F or more. The warming has been especially pronounced recently, as the last three falls have been within the

Fall Nights Are Warming in Our Changing Climate

Fall is a season of transition and big swings in weather; snow has already fallen in the Front Range of the Rockies, while warm and humid conditions hung over the East Coast as recently as last week. As the climate changes, fall is not as cool as it used to be, and cooler weather is being delayed until later in the season. This change affects the

A 2018 Summer of Extremes

Meteorological summer has been one of extremes in the U.S. Overall, the East has been wet while the West has baked in the heat. These types of extremes, which are set up by a consistent jet stream pattern, are amplified by a warming climate. Many locations in the Middle Atlantic, Ohio Valley, and Upper Midwest had one of their 10 wettest summers

fishing and climate change

How Climate Change Affects Fishing

Each year, more than 49 million Americans fish recreationally in freshwater rivers and lakes. Some fish to relax, and some for the thrill. But in a changing climate, a new generation of anglers will have to get used to conditions far different from those of their parents and grandparents. Warming water in streams, rivers, and lakes is changing the

Smoke Wave Days in the Western U.S.

The U.S. has come a long way in cleaning up its air. The Clean Air Act of 1970 made air pollution catastrophes like the 1948 smog that killed nearly 40 people near Pittsburgh a distant memory. But while the air is much cleaner overall, smoke from wildfires is threatening the progress that’s been made, as particulate pollution from wildfires has

Mosquito Disease Danger Days

The number of days each year that are suitable for disease transmission by mosquitoes is rising in much of the U.S., as temperatures climb with climate change. This can increase the risk of mosquito-borne diseases such as Zika and West Nile. Following research from Stanford University, Climate Central analyzed the number of days in the spring,

Longer Heat Streaks

The summer doldrums have set in for much of the U.S., but an end to the Dog Days of summer is within sight. The Dog Days traditionally extend from July 3 to August 11, when Sirius (aka the Dog Star) rises and sets with the sun. Ancient cultures believed that additional energy from Sirius helped make the summer days hotter, but in modern times, the

Extremely Hot Days on the Rise

Late July is the hottest time of year for much of the country. In the midst of this summer heat, we calculated the number of extremely hot days each year in 244 cities across the country and found that 73 percent experience more extremely hot days than they did a half-century ago.

2018 U.S. Temps: State Rankings Through June

Despite a cold April, 2018 is the 14th warmest year on record so far in the U.S. Halfway through the year, Arizona and New Mexico are record hot, and the remaining southwestern states are each having one of their 10 hottest years. In fact, the four hottest years in the U.S. have all come in the decade of the 2010s. July has been a scorcher from
