climate change

If you think it's been hot this year, you're right. The latest temperature numbers from NASA and the National Oceanic and Atmospheric Administration say the first six months of 2016 were the hottest on record around the planet.

The way clouds cover the Earth may be changing because of global warming, according to a study published Monday that used satellite data to track cloud patterns across about two decades, starting in the 1980s.

Clouds in the mid-latitudes shifted toward the poles during that period, as the subtropical dry zones expanded and the highest cloud-tops got higher.

Climate change is a global issue. But for Betty Barkha, it's personal.

Mounting risks because of climate change are putting pressure on insurance companies. That has Washington's Insurance Commissioner worried. He’s hosting a climate risk summit meeting at the University of Washington this week.  

Cows are notoriously gassy creatures. Globally, more than a third of methane generated by human activity comes from livestock farming, a good deal of it in the form of bovine belching (yes, belching — not the other end). This is a serious problem, given that methane is 25 times more powerful than carbon dioxide at trapping heat.

Hundreds of activists are gathering in Anacortes this weekend for protests aimed at keeping fossil fuels in the ground.

The Pacific Northwest “Break Free from Fossil Fuels” event is part of two weeks of actions that have been taking place in dozens of cities all over the globe. Other U.S. cities on the list include Denver, Los Angeles, Washington, D.C. and Chicago. 

Local authorities are warning residents to prepare for congestion.

Coastal cities across the globe are looking for ways to protect themselves from sea level rise and extreme weather. In the U.S., there is no set funding stream to help — leaving each city to figure out solutions for itself.

New Orleans and Philadelphia are two cities that face very similar challenges of flooding from rising tides. But they've chosen to pay for the solutions in very different ways.

Western Washington’s unseasonably high temperatures will be subsiding, but KPLU weather expert Cliff Mass says you may want to keep the shorts and sunglasses handy.

“I’d keep them around,” Mass said, though he added that many people will be needing them less over the weekend. He said Friday will still be very warm and sunny.

Another Hot Day Friday – Except On The Coast

“Maybe not quite as warm as yesterday, in some places,” he said, but the air above us is still “warmer than we generally see till the middle of summer.”

A new study suggests that sea levels are rising at an unprecedented rate and that the problem will continue well into this century.

"Sea level rise in the 20th century was truly extraordinary by historical standards," says Bob Kopp, an associate professor of Earth and planetary sciences at Rutgers University, and who is lead author on the study, which appears in the journal Proceedings of the National Academy of Sciences.

Many middle and high school science teachers are getting climate change wrong.

That's according to the results of a new, national teacher survey backed by the National Center for Science Education and published in the journal Science.

Before we get to those results, a quick, climate science refresher is in order.

NPR science correspondent Christopher Joyce says the world's major scientific organizations are now clear on global warming:

A massive die-off of sea stars a few years ago was caused by a virus. But a study published this week shows that higher water temperatures also played a big role.

It's not rare for a year to break record temperatures. But it's now happened two years in a row — and 2015 was "very, very clearly the warmest year by a long chalk," says Gavin Schmidt, director of NASA's Goddard Institute for Space Studies.

Five activists who joined forces in an attempt to stop oil and coal  trains from traveling through the Northwest have been convicted of criminal trespassing. That’s after a jury in Lynnwood handed down its verdict on Friday.

The so-called “Delta 5” lost their key argument, about whether it was necessary to chain themselves to the train tracks along with a huge tripod and banner, designed to stop the trains.

As lawmakers reconvene in Olympia, legislative proposals to limit carbon pollution are piling up. All are ideas that address how to curb the greenhouse gas emissions that cause climate change.

Some involve a cap-and-trade system, similar to what California and some New England states have done.

Others are straight taxes, following British Columbia’s example.

How to limit the carbon pollution that causes climate change and global warming is a key issue as lawmakers get going in Olympia this week. Dozens of legislative proposals have been submitted on the topic, some with multiple versions that use very minor changes in wording in attempts to see which proposals would have the best chances of passing.

University of Washington scientists hope to better forecast climate change by harvesting weather data from 19th-century whaling boats.

For centuries, sailors have been making detailed observations about the weather, and that information has sat archived in yellowing log books. But now research scientist Kevin Wood of the UW and NOAA’s Joint Institute for the Study of the Atmosphere and the Ocean, says scientists can put that historical data to use.

Activists from Seattle got the support of health care professionals and faith leaders in their call for the Gates Foundation to divest from fossil fuels.

The announcement of about a thousand new supporters of the divestment campaign came on the same day that Bill Gates made a major statement on climate change.

He joined forces with Facebook founder Mark Zuckerberg and several other business leaders to launch a multi-billion dollar clean energy fund in Paris, where the U.N. climate talks are now underway. It’s an effort to promote things like solar energy and wind power.

Climate change isn't just something to worry about here on Earth. New research published today shows that Mars has undergone a dramatic climate shift in the past that has rendered much of the planet inhospitable to life.

About 3.8 billion years ago, Mars was a reasonably pleasant place. It had a thick atmosphere filled with carbon dioxide that kept it warm. Rivers trickled into lakes across its surface. Some researchers think there might even have been an ocean.

Kids packed a courtroom in Seattle on Tuesday to hear oral arguments in a case about their future. Eight young teenagers are the plaintiffs in a lawsuit against the state Department of Ecology. They want to force action on climate change.

“It just feels like there’s not enough people who care about, like, animals and other things that can’t talk for themselves – babies who haven’t been born yet, people from the future, basically,” said 13-year-old Lara Fain.

More than 150 groups in Washington state have come together to form the Alliance for Jobs and Clean Energy. It’s an effort to fight climate change that some are calling “historic in scope.” The consortium has announced plans to put a statewide carbon-capping initiative before voters in 2016.

The predicted effects of global climate change are grim, to say the least. Global warming is expected to cause more extreme weather events, as well as a rise in sea level, drought and flooding; it’s not a pretty picture.

But, according to weather blogger and KPLU commentator Cliff Mass, it won’t actually be that bad here in the Northwest.

  Royal Dutch Shell PLC says it's ceasing exploration in offshore Alaska for the foreseeable future.The company says an exploratory well drilled to 6,800 feet found oil and gas but not in sufficient quantities.

Shell USA President Marvin Odum says in an announcement early Monday in The Netherlands that it's a disappointing outcome for that part of the Chukchi Sea basin. Shell drilled in 150 feet of water about 80 miles off Alaska's northwest coast.The exploratory well was the first in the Chukchi in 24 years.

The administration of Washington Governor Jay Inslee has officially begun crafting new rules to cap greenhouse gas pollution from large industrial sources. Inslee is flexing his executive powers to bypass the state legislature, which has repeatedly chosen not to put a price on carbon.

The Environmental Protection Agency says Volkswagen intentionally violated the Clean Air Act by using sophisticated software in its diesel-powered cars that detects emissions testing — and "turns full emissions controls on only during the test."

Installed in four-cylinder cars, the software, which the EPA calls a "defeat device" that's meant to trick official tests, allowed diesel Jettas, Beetles and other cars to "emit up to 40 times more pollution" than allowed under U.S. emission standards.

Mount Rainier is famous as the most glaciated peak in  the contiguous United States. But the massive flows of ice and snow that cover the mountain are retreating rapidly, likely more rapidly than ever in the record warmth of this summer.

Participants in the 2015 "Climate Boot Camp" put on by the Northwest Climate Science Center gathered this week in Mount Rainier National Park to learn more about the dynamics behind this phenomenon.

Seattle Mayor Ed Murray is in Rome this morning (Tues.)  for the first ever gathering of mayors at the Vatican.

They’re there to discuss human trafficking – as well as climate change and the role of cities in fighting it. 

Murray joins mayors from New York City, Boston, San Francisco and Portland as well as Mexico City, Berlin and Oslo, among others. Pope Francis invited the municipal leaders, calling for a renewed international conversation about ending social and environmental exploitation.
