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 …

Beyond the Data on The Planet’s Temperature

Deke Arndt at NOAA is one of the smartest climatologists around, and I always look forward to hearing him talk, because he takes data and makes you see it in a way you did not immediately think about. By the way, for those of you who are still in school, some sage advice: always hang around with people smarter than you. You’ll never learn anything by being the smartest person in …

Why Some Teachers Are Teaching Climate Change Wrong

I mentioned this subject last week, and thanks to my friend Ed Maibach at George Mason Univ. for the tip about this op-ed piece in U.S. News and World Report. It’s well worth a read, and I agree with the authors that the likely reason for this is that teachers are unaware of the overwhelming consensus among scientists. There’s no greater science myth in America, than the stubborn belief that …

Paper shows Significant Increase in Methane Emissions in U.S.

Despite the plentiful commercials on cable networks touting clean natural gas, there is more to the story. Methane emissions have noticeably increased in the U.S. according to research published in the AGU journal Geophysical Research Letters. There has been a lot of talk recently about how much natural gas escapes from fracking wells and the huge leak in Southern California has been national news for over two months. Methane is …

NOAA Data Confirms NASA Data- January 2016 Hottest Month On Record

The National Centers for Environmental Prediction (formerly the Nat. Climate Data Center) posted their monthly global temperature data and it (like NASA) shows January to be the hottest month on their data base. The thermometer record goes back to 1880, but proxy data shows this was likely the hottest month on the planet in at least 2,000 years. This is the 9th month in a row with a new monthly …

Climate Change and Teachers

There is a very noteworthy paper out today in Science about the teaching of climate science in America’s classrooms, and it’s open source, so non-subscribers can read it. The piece is excellent, so if you know are (or know) a teacher, please share it with them.  The short summary of the Science paper, is that some teachers are telling students things about science that the facts just do not support, chief among …

New study suggests northern tundra shifting from carbon sink to carbon source

Arctic tundra stores carbon during the summer and releases some of it during the winter. But a new study shows that carbon released during the winter now outweighs the summertime gains, resulting in a net loss of carbon to the atmosphere. According to the study’s authors, these results suggest the northern tundra may be shifting from its historical role as a carbon sink to a carbon source.

How stable is the West Antarctic Ice Sheet?

A future warming of the Southern Ocean caused by rising greenhouse gas concentrations in the atmosphere may severely disrupt the stability of the West Antarctic Ice Sheet, which would raise sea levels by several meters, according to new research. A temperature increase of 2 degrees Celsius (3.6 degrees Fahrenheit) would be enough to initiate irreversible melting of the ice sheet, the new study found.

60 Minutes of Real Climate Science

It’s almost impossible for the average person with no science background to get good basic info about climate change (on TV or online). So, here’s some information that you can rely on. First dispelling a popular myth, and then a lecture by Dr. Michael Mann to Physics students at the Univ. of Virginia recently. Regurgitated Climate Myth Those who find the truth extremely inconvenient to their political worldview, love to …
