Sea level rising faster now than during 1990s, new study shows

Global mean sea level is rising 25 percent faster now than it did during the late 20th century largely due to increased melting of the Greenland Ice Sheet, a new study shows. Satellites first started measuring sea level rise in 1993. The new study revisits how well these measurements agree with independently observed changes in the various components contributing to sea level rise.

Thousands Stand Up for Mankind’s Greatest Invention- Science

Thousands of scientists from around the world did something that seemed unimaginable a few years ago. They stood up and made their voices heard in defense of science. Thousands of scientists braved a steady light rain and cool temperatures to gather on the Mall in Washington today and then marched toward the Capitol. The rain was not a surprise because the forecast for the day was nearly spot-on (thanks to …

Science: “An Exercise in Finding What’s True”

Neil de Grasse Tyson’s video below is a must watch. His quote that “Science in an entire exercise in finding what is true”, is similar to another quote that I’ve often repeated from Richard Feynman: “Science is what we do to keep from lying to ourselves.” Watch the video and then share it.

How the Disappearing Arctic Ice is Already Changing Your Weather

It’s called Arctic Amplification and it’s easy to understand. As the snow and ice disappear in the high latitudes, what was once bright and reflective, is now dark and warmer. Warmer because the solar energy it used to reflect is being absorbed, and this warming is not just a prediction, it’s been measured. The high latitudes are warming dramatically more than the tropical oceans. But, how is this affecting our daily weather? …

Dr Michael Mann on Science Friday

Science Friday had an excellent interview with Penn State Climatologist Michael Mann today, and you can hear it all here. Dr Mann produced the “hockey stick”, which is destined to become one of the most famous images in the history of science, and it’s caused him plenty of grief. If he’d been wrong, it would not have been so bad! Unfortunately for him, he was right, and that made the …

The Disappearing Ice- Pictures tell the Story (The Science Explains Why)

Seth Borenstein at the AP has a story out today about a must see (upcoming) paper in the journal GSA Today. The article has some amazing photos of the rapidly melting ice across the planet, and they’re stunning. I highly recommend reading the paper and not just looking at the photos. Also, you will see a photo credit for Lonnie Thompson, and trust me you should read Mark Bowen’s book …

Don’t Like The Science- Make up Your Own Alternative Science

Make up your own science and then send it to 200,000 teachers. This will turn out to be a real waste of money for Heartland, and the reason is that most Earth science teachers will toss this in the waste bin. That’s a good place for it, but before you do, you could use it to explain what real peer-reviewed science is compared to an opinion based on worldview. It’s also …

The Fake Climate Debate and The Real One

I just finished reading a paper by Michael Mann, Stefan Rahmstorf et.al in Nature Reports today that is getting some deserved press attention. It’s rather complicated (OK, for non-atmospheric science geeks, it’s a brick) but in plain language, it indicates that the warming of the climate is doing what many of my fellow forecasters have been suspecting for quite some time: changing the upper-level wind flow and therefore changing our …

Sea Ice and China Smog

Even Antarctica saw record low ice area during their summer (boreal winter), but there’s new research that seems to show a link between the Arctic ice loss and increased air pollution in China. With dark, heat-absorbing water now replacing what was once bright and very reflective ice, the energy balance of the atmosphere has to change, and that change translates to changing weather patterns. There is quite a bit of research into this now, …

February Second Warmest on Record

This February was 1.76°F (0.98°C) above the 20th-century average. The only February that was hotter was in 2016. When compared to the 20th-century average, February was the 7th hottest of any month on record The last February below the 20th-century average was in 1976. The rate of the February temperature increase has doubled since 1980. 15 of the 20 warmest Februaries have come since 2000. None were before 1983. February …

Conspiracy Theory Myths are Not Alternative Scientific Opinions. They are Just Wrong.

I saw this headline today: You see this kind of claim all over conspiracy theory sites online, but it’s just that: a silly conspiracy theory. Let me explain. This is the same as the Surgeon General saying that “We are not totally sure that the oxygen in the air is what keeps us alive”. The science is beyond overwhelming here because there’s no reasonable scientific doubt that the warming over …

Climate change puts California’s snowpack under the weather

Skiing in July? It could happen this year, but California’s days of bountiful snow are numbered. The Sierra Nevada snowpack, which provides 60 percent of the state’s water via a vast network of dams and reservoirs, has already been diminished by human-induced climate change and if emissions levels aren’t reduced, the snowpack could largely disappear during droughts, a new study finds.

Weathercaster Survey Shows Increasing Acceptance of Climate Science

The Center for Climate Change Communication at George Mason University is out with its latest survey of TV weathercasters and their views on climate change. For the most part, it’s good news, and I was one of the survey participants. Full disclosure: I’m doing a talk on science communication with one of the authors of the study (Ed Maibach) at the American Meteorological Society (AMS) Broadcast Meteorology conference in June. Just …

Study improves forecasts of summer Arctic sea ice

Each year, as sea ice starts to melt in the spring following its maximum wintertime extent, scientists still struggle to estimate exactly how much ice they expect will disappear through the melt season. Now, a new NASA forecasting model based on satellite measurements is allowing researchers to make better estimates.

Are we living in a warm peak between ice ages?

By Ned Rozell As another major rainstorm hit California in February, downtown San Francisco surpassed its normal rain total for an entire year. Reservoirs in the high country were spilling over. So ended a five-year drought in the state that some people attributed to human-caused climate change. Those pictures of dried-up California lakes bothered Syun-Ichi Akasofu, who recently gave a talk “The Forthcoming Ice Age” at the University of Alaska …

How Do Climate Models Work? Answer Here.

Keith Dixon is one of my go-to people when I have a question about climate modelling, so when Climate Central said they were going to host a webinar with Keith, I begged them to record it. They did! Now, this was done for meteorologists, so a bit of a geek alert here, but I think you will find it fascinating, even if you have no atmospheric science background. So, watch …

Ancient cave reveals recent droughts in the Middle East were most severe for over a millennium

A stalagmite collected from a remote cave in the Middle East has revealed that recent droughts there were more severe than previously thought, and therefore possibly an important contributing factor for the turmoil in Syria. A research team traveled to Iraq to collect the stalagmite and used it to present the first ever detailed climate reconstruction of the Fertile Crescent extending back 2,400 years.

Support for A Clean Energy Economy is Higher Than You Might Think

Ed Maibach and his group at George Mason University are out with another report about how American’s feel about climate change and clean energy. Prepare to be surprised by the level of support in this survey, which targeted strongly conservative voters. I talk often to groups about climate change and science and find these surveys indispensable in knowing my audience. Ed, John Cook*, and I are planning a joint talk at the …

The Graph The Daily Mail Does Not Want You To See

The Daily Mail says that NOAA is manipulating the climate data! No, really? That’s certainly a first for them. NOT. Here is a graph they published as proof. Now, there is just one tiny problem, well actually, there are a bunch of them. The Hadley (UK) data is based on an average from 1961-1990 while the NOAA data they plotted is based on 1901-2000. The baseline choice does not make …
