New study suggests less snow, earlier snowmelt at higher elevations in warming climate

Spring snowpack, relied on by ski resorts and water managers throughout the Western United States, may be more vulnerable to a warming climate in coming decades, according to a new study.

Funding Season is Open: Part 3

Thanks for staying with us as we continue to break down federal science funding for fiscal year 2017 (FY2017). To completely understand how the FY2017 landscape is evolving, I encourage you to check out the first and second parts of our funding Bridge posts. As you’ll recall, we previously laid out the good and bad of the Senate’s appropriations bill covering NASA, DOE’s Office of Science, NOAA, and the National …

Tidal Troubles In The Mid-Atlantic

NOTE: This post is based on some research I did for an on-air story that aired today: Sea level rise is what’s called a slow motion disaster. These kind of events tend to be blamed on the symptoms rather than the cause, and often the preparation/ response to these type of events is inadequate. This is much the case where I live and work here in the Mid-Atlantic, on the …

NOAA: April Temps Hottest On Record for 12th Straight Month

NOAA has followed NASA with their own analysis of the global temp. in April, and it’s nothing less than stunning. Another NOAA report out shows that Human activity has increased the direct warming effect of carbon dioxide (CO2) in the atmosphere by 50 percent above pre-industrial levels during the past 25 years From NOAA: The globally averaged temperature over land and ocean surfaces for April 2016 was the highest for …

Earth’s Atmosphere Passes Significant Carbon Milestone

This is from the National Center for Atmospheric Research in Boulder, Colorado: May 12, 2016 | Earth’s atmosphere is crossing a major threshold, as high levels of carbon dioxide (CO2)—the leading driver of recent climate change—are beginning to extend even to the globe’s most remote region. Scientists flying near Antarctica this winter captured the moment with airborne CO2 sensors during a field project to better understand the Southern Ocean’s role …

Climate change could cause more concentrated storms

Rising temperatures are causing heavy rain storms to become concentrated over smaller areas, a scenario that could potentially cause extreme flooding in urban locations, according to new research.

Scientists search the seas for soot

Earth system scientists from the University of California, Irvine have taken water samples from the north Pacific, north and south Atlantic, and Arctic oceans in search of repositories of black carbon, soot from burning biomass and diesel engines, among other sources. They’ve found considerably less of the material than expected, and they’ve discovered that it exists in at least two varieties, a younger pool closer to the ocean’s surface that is absorbed into the environment in a roughly 100-year cycle and an ancient reserve that remains stable for millennia.

Visualizing the Heating of the Planet

An ingenious animated graphic by Ed Hawkins (Climate scientist at the Uni. of Reading in the UK) is going viral online today, and it is well worth sharing. Finding a new way to show raw data in a way that allows you to visualize what is happening, is always worth pursuing. Ed has another graph that shows how 2016 so far compares to last year. Last year was the warmest …

Roaring Inferno in Alberta is What Climate Change Looks Like.

The wildfire in NW Alberta grew much larger overnight and now over 85,000 people are evacuated as fire crews try to save the city. The question about how this is related to climate change is an easy one, a very easy one. It is related, and the data backs it up. Jeff Masters (at Weather Underground) has an exc. post on this, and he posted a graph from Rutgers (see …

Kudos to Jimmy Kimmel For Supporting Reason over Myth

Warning for semi-strong language, but well worth watching.   An education teaches you how much you do not know. Unfortunately, Mrs. Palin does not seem to have a clue about that. Read this to understand how much heat energy the CO2 is trapping.

The Consensus on the Consensus Is Itself Overwhelming

My friend Ed Maibach at George Mason Univ. emailed me some interesting abstracts today that show how overwhelming the consensus is on climate change among scientists working in the field. Researchers like Ed and Dr. Oreskes (among others) have shown that the consensus now is nearly unanimous among those in the field. The belief that scientists are divided over the question must be the greatest scientific myth in the United …

You Can Thank These Three People for Earth Day

I remember very well watching the CBS Evening News (46 years ago today) on the first Earth Day. It was a major story, and I believe Walter Cronkite led the broadcast with it. We know a lot more about our planet now than we did then, and there have been some amazing successes in protecting our environment. We now know something that was not well understood then, and that is the …

NASA/NOAA/ Data All Show Hottest March Ever

NOAA and NASA both have released the global temp. data and not only did it break a record for the 11th consecutive month (Something that has never happened before), it also broke the previous March record by a record amount. NASA reported the global March temp. was 1.28C above the average from 1950-1980. Keep in mind that there’s a strong scientific consensus that any rise above 2 degrees C in …

An Ocean Mystery

A little science mystery for you. Look at this image above (Courtesy Climate Central in Princeton). Why is the water south of Greenland getting colder/not warming, while its warmed dramatically elsewhere?? Current hypothesis is melting ice in Greenland is chilling the water, or a slow down in the thermohaline circulation. May be both? Last I heard the climate models were not reproducing it well, but if it is melting ice, …

As The Science Gets Better, The News Gets Worse on Sea Level Rise

I spent the weekend reading the new paper in Nature last week that made a lot of news. (Justin Gillis at The NY Times has an excellent summary of the paper here). If you missed it, the short version is that for the first time, researchers used a series of coupled models to produce a more realistic look at what will happen to Antarctica in the coming decades and centuries. There …

This Is Why The Record Warmth is Not Natural

Lots of talk about the global record temperatures that both NOAA and NASA (They do separate calculations) announced this week, but here’s something that doesn’t get as much attention, and should. Look at the graph above, it shows two different temperature traces. The red line is the actual global temps. since about 1880. Black line is the CMIP 5 model average forecast when you put in CO2, volcanic eruptions, minute …

NOAA: 10th Record Month in A Row. Temperature Off the Charts

February 2016 was the hottest month ever measured on Earth. The planet broke a heat record for the 10th month in a row in February and we broke it by a record amount as well. The heat was nothing short of amazing with Alaska averaging out at over 12 degrees above normal. That is nothing less than stunning. The odds that this warmth is part of a natural cycle have …

NASA: February Temperatures Hottest Ever

  NASA has released the February global temperature data, and the rumors that it would smash the record set just last month by an incredible margin are true. The global temp. was 1.35C above the average of 1951-1980. This passes last month’s record of 1.14C above that average. The overwhelming opinion of experts is that any rise above 2 degrees C will bring unexpected and serious consequences to our climate …

Attributing Extreme Weather Events to Climate Change

My friend Heidi Cullen at Climate Central in Princeton has an excellent Op-Ed in the New York Times today. It’s about a new study released by the National Academies on attributing extreme weather events to climate change. The study itself is on my reading list for tonight, and you can read it yourself for free. Just click the image below. I know several of the researchers who worked on this …

This Winter Was The Warmest On Record Nationwide

From NOAA NCEI: The December–February average temperature for the contiguous U.S. was 36.8°F, 4.6°F above the 20th century average, surpassing the previous record of 36.5°F set in 1999/2000. The exceptionally warm December boosted the contiguous U.S. winter temperature. The February temperature for the contiguous U.S. was 39.5°F, 5.7°F above the 20th century average, ranking as the seventh warmest on record and warmest since 2000. Preliminary indications are that globally, February …
