Rising Seas Spark Tobacco-Style Lawsuits in California

Rising Seas Spark Tobacco-Style Lawsuits in California

Several flood-prone municipalities in California filed first-of-their-kind lawsuits against fossil fuel companies this week as they attempt to recoup the cost of coping with rising seas. The suits point to indisputable climate science and decades of industry efforts to mar that science. Experts likened the legal complaints to those brought against… Read More

At Midway Point, 2017 Is 2nd-Hottest Year on Record

At Midway Point, 2017 Is 2nd-Hottest Year on Record

At the halfway point of the year, 2017 remains the second-hottest year to date — a surprise given the demise of the El Niño that helped boost temperatures to record levels last year. The continued near-record warmth is a marker of just how much global temperatures have risen thanks to the greenhouse gases accumulating in the atmosphere from fossil… Read More

Today’s Extreme Heat May Become Norm Within a Decade

Today’s Extreme Heat May Become Norm Within a Decade

When 2015 blew the record for hottest year out of the water, it made headlines around the world. But a heat record that was so remarkable only two years ago will be just another year by 2040 at the latest, and possibly as early as 2020, regardless of whether the greenhouse gas emissions warming the planet are curtailed. That is the conclusion of a… Read More

Greenhouse Gases Are Rapidly Changing the Atmosphere

Greenhouse Gases Are Rapidly Changing the Atmosphere

Humanity’s grand experiment in the atmosphere continues, and a new report documents just how far it’s gone. On Tuesday, the National Oceanic and Atmospheric Administration released its annual index of 20 key greenhouse gases. It shows that their direct influence on the climate has risen 140 percent since 1750, with 40 percent of that rise coming… Read More

Rising Temps Could Bring Flight Delays Worldwide

Rising Temps Could Bring Flight Delays Worldwide

Imagine boarding a summertime flight at LaGuardia Airport in New York City, only to be told that the airline needs a dozen or so passengers to take a later flight because it’s too hot outside for the plane to take off fully loaded. That could become a common scenario at 19 major airports worldwide as extreme heat caused by global warming disrupts … Read More

Arctic Heat Is Becoming More Common and Persistent

Arctic Heat Is Becoming More Common and Persistent

The Arctic is a bastion of cold, blustery weather. But in the latest sign of how quickly changes are happening, new research published this week shows that the Arctic has seen more frequent bouts of warm air and longer stretches of mild weather. The new findings show that while warm snaps have occurred even as far as back as the 1890s, a massive… Read More

The West Is on Fire As Heat Records Fall

The West Is on Fire As Heat Records Fall

From Phoenix to Boise, high temperature records fell like dominoes over the weekend as an impressive heat wave engulfed the western U.S., helping to fuel several wildfires. While heat waves are a regular part of summer weather, the steady warming of the planet means those heat waves are getting ever hotter, making record heat more and more likely… Read More

The Arctic Has Been Crazy Warm All Year. This Is What It Means for Sea Ice

The Arctic Has Been Crazy Warm All Year. This Is What It Means for Sea Ice

Melt season has begun in earnest in the Arctic. Scientists will spend the next few months watching sea ice turn into open water until the ice pack hits its nadir in early fall. The vagaries of the weather and ocean currents will play a major role in determining where this year’s Arctic sea ice minimum ranks. But the steady drumbeat of climate… Read More
