A warming climate is affecting the natural ranges of plants around the country.

Earlier Springs Heighten Allergies

As global temperatures continue to rise, Knoxville is experiencing earlier springs, ushering in longer allergy seasons. Pollen intensity is increasing, inducing sickening impacts for asthmatics and those vulnerable to hay fever. “We’ve already seen this happen on a national scale,” says David Peden, who estimates that an additional 10 to 15 percent of the population will be afflicted with allergies by 2050. With national allergy management costs averaging $18 billion per year, the financial burden can weigh heavily on lower income families.

February 2019 ranked fifth hottest on record

Steady warmth around the globe made February the fifth hottest on record. Seasonally, the period from December 2018 through February 2019 ranked fourth hottest on record, according to scientists at […] more »

March 2019 El Niño Update: Think spring

El Niño’s effect on global circulation is weaker in the spring than in winter, but still detectable. Historical global temperature and rain patterns during El Niño in the spring show less rain than average over a lot of the tropics, for example. Weak El Niño conditions mean these impacts may be less consistent than during strong El Niño. Check the Climate Prediction Center for an outlook on US seasonal patterns. El Niño conditions through the summer can affect the hurricane season, too—the Climate Prediction Center’s hurricane season outlook will be issued in May, so stay tuned!

Trending: Scientists simulate forest and fire dynamics to understand area burn of future wildfires

New wildfire simulation models suggest that the fuel limitation effect from prior fire events where prior fires reduces the amount of fuel available to burn in the forest doesn’t last very long and is not nearly as significant a limitation for future fires as was expected.

CLIMATE PILE-UP: Global Warming’s Compounding Dangers

Recent research shows that unchecked warming pollution could bring concurrent climate crises to U.S. cities by midcentury — and that emissions cuts could reduce the risk.

EESI Reports: 2018 was the Fourth-Hottest Year on Record

The New York Times features NASA report that the Earth’s average surface temperature in 2018 was the fourth highest in nearly 140 years of record-keeping and a continuation of an unmistakable warming trend.

Trending: A warming world increases air pollution

A new study shows that the contrast in warming between the continents and sea, called the land-sea warming contrast, drives an increased concentration of aerosols in the atmosphere that cause air pollution.

ON THIN ICE: How Climate Change is Shaping Winter Recreation

Climate Central assessed annual snowfall data from 107 weather stations across the United States, dating from 1970 to 2018. The results showed stark regional differences, with serious consequences for America’s cold-weather sports economy.

Major northeastern U.S. snowstorms expected to continue with climate change

Even though climate change is expected to reduce the total amount of U.S. snowfall this century, it’s unlikely to significantly rein in the most powerful nor’easters that pummel the East Coast, new research indicates.
