Scientists Warn of Summer Heat Spikes as Global Warming Edges Toward 2C

Former federal climate experts warn that atmospheric carbon dioxide concentrations hit a record high in May and that the monthly average global temperature this summer could rise as much as 3.5 degrees Fahrenheit (1.9 degrees Celsius) above the pre-industrial benchmark used to measure the heating from greenhouse gases. Research shows human-caused warming will contribute significantly […]

No, New York Times, Climate Change Is Not Making Tennis Players Ill

The NYT’s desperation to turn a story about players losing matches due to illness or the intensity of the game in tough conditions into a climate change story just goes to show that climate realists currently hold the advantage point. Alarmists seem worried that any lost opportunity to mention climate change will result in game, set, match for realists.

Live at 1 PM ET: Europe Boils – The Climate Realism Show #204

Summer has arrived in Europe a little early this year and alarmists in the media say it’s unprecedented, dangerous, all because of climate change. But what if it is not our fault? What if it’s not all that unusual? We will sweat the details.

An Unusually Early Heat Wave Breaks Temperature Records Across Western Europe

Extreme heat is one of the most dangerous climate change risks in the United Kingdom, according to a new government-backed report that warned the nation is “built for a climate that no longer exists.” Right after it came out, the U.K. recorded its hottest day on record for the month of May. The temperature at […]

Latin America Faces ‘Hydrological Whiplash’ as Climate Risks Mount

If the 2025 climate year in Latin America and the Caribbean showed anything, it was that floodwaters can’t erase long-term drought, that temperatures will continue to soar past livable limits and that once-unprecedented storms are part of the region’s new climate reality. A World Meteorological Organization report released Monday shows that Mexico alone experienced all […]

An Unusual Heat Wave Strains the World’s Most Populous Country

Every one of the world’s 50 hottest cities was located inside India at the end of April—a global weather-tracking anomaly, according to a major air-quality monitoring platform. As an unusual early-season heat wave gripped the country, average peak temperatures across the most sweltering cities hit around 112 degrees Fahrenheit on April 27, data from the […]

New paper: U.S. temperature extremes have declined since 1899, challenging assumptions about increasing heatwaves

The result is simple: both hot and cold extremes have declined over the full period of record.

How Forests Start to Fail, One Leaf at a Time

In spring and summer, the canopies of oak and beech forest gather into layers of green. Leaves flicker, shaping the flow of light and air. The effect is almost effortless, a shaded world held in balance. But as heatwaves and droughts intensify, that balance is starting to slip, and the first signs of stress often […]

Extreme Heat Watches issued for California and Arizona as anomalous heat intensifies across parts of the Southwest

Extreme Heat Watches have been issued for parts of California and Arizona as an anomalous and unusually prolonged heat event intensifies across the Southwest United States. Watches begin Monday, March 16, 2026, in parts of Southern California, then expand into parts of Arizona and southeast California later in the week, with some desert areas forecast to reach up to 43°C (109°F) and temperatures…

Summer in March? Unusual Heat Wave Descends on Already Parched Western U.S.

An early-season heat wave is descending across the Western United States, likely to bring record-shattering temperatures to much of the region. Temperatures already climbed into the 90s on Thursday in states such as Arizona and California and are expected to peak on Friday before the dome expands to the Mountain West and parts of Oregon […]

Whale Entanglements in Fishing Gear Surge Off U.S. West Coast During Marine Heatwaves

Each spring, humpback whales start to feed off the coast of California and Oregon on dense schools of anchovies, sardines and krill—prey sustained by cool, nutrient-rich water that seasonal winds draw up from the deep ocean. That process, known as coastal upwelling, turns the California Current into one of the most productive marine ecosystems in […]

Dutch climate skeptics vindicated: KNMI reinstates seven pre-1950 heatwaves after long battle

Seven years after Dutch skeptics first challenged KNMI’s temperature adjustments, the institute has reinstated seven “lost” pre-1950 heatwaves at De Bilt — validating claims of over-correction that had erased 16 out of 23 historical extremes. The breakthrough came via the skeptics’ peer-reviewed paper.
