176 Years of Global Temperatures in One Image

176 Years of Global Temperatures in One Image

From Ed Hawkins at The Univ, of Reading. The visualisation technique of ‘small multiples’ is often used to communicate a simple message. The above example shows maps of temperature change from 1850-2016 – the overall warming trend is obvious even though the details are fuzzy. Technical details: The HadCRUT4.4 dataset is used with anomalies from a 1961-1990 baseline period. An annual average for a particular grid cell and year is …

30 Deaths from Lightning in the U.S. So Far This Year. 12 From Tornadoes

30 Deaths from Lightning in the U.S. So Far This Year.  12 From Tornadoes

Meteorologist John Jensenius at NOAA keeps track of the deaths from lightning each year, and I asked him to send me a list of the deaths each month, so that I could share. We are now up to 30, and it is worth noting that 80% of the deaths are male and 20% female, a fact that is not unusual, with far more males rather than females becoming victims each …

Big Trouble Brewing For Southeast U.S.??

Big Trouble Brewing For Southeast U.S.??

Tropical Update : I’m not going to post any specific model data since there is still quite a bit of disagreement, and any individual run this far out is worthless, but that said: My concern that a tropical cyclone will threaten the SE U.S. in 5-7 days is growing rapidly. The system is looking much healthier on the satellite images tonight. Increased convection and shear seems less. The wind shear …

The Tropical Atlantic is Starting Bubble

The Tropical Atlantic is Starting Bubble

Tropical Storm Gaston formed late Monday evening in the Atlantic, and will likely become a hurricane in a few days. It will also likely stay far from land, and recurve into the North Atlantic. Another tropical disturbance in the western Caribbean does bear watching as it might move toward the Bahamas in about 5-7 days. There is a lot of uncertainty though with this system and a large disagreement among …

Here Is How We Get More Women In Science

Here Is How We Get More Women In Science

I ran across what I think is an important paper in PLOS One this week, and it involves women and STEM careers. Go to any science conference, and you see far fewer women than men, and this paper may have hit on why this is the case. In general, women do not seem to have the confidence that they can get through calculus, and make no mistake about it, it’s …

NOAA Data Confirms NASA and Japan: July 2016 was Hottest on Record.

NOAA Data Confirms NASA and Japan: July 2016 was Hottest on Record.

From NOAA: For the 15th consecutive month, the global land and ocean temperature departure from average was the highest since global temperature records began in 1880. This marks the longest such streak in NOAA’s 137 years of record keeping. The July 2016 combined average temperature over global land and ocean surfaces was 0.87°C (1.57°F) above the 20th century average, besting the previous July record set in 2015 by 0.06°C (0.11°F). …

You’ll See More and More About Climate on TV Weathercasts. Here’s Why.

You'll See More and More About Climate on TV Weathercasts. Here's Why.

I’ve written about this subject many times here, but here is a nice video (from Peter Sinclair, and Yale Climate connections) explaining why broadcast meteorologists around the country can no longer ignore the changing climate.   You may recognize a few of us, depending on where you live.

Another Melted Record- NASA Says July Hottest Month Ever Measured on Earth

Another Melted Record- NASA Says July Hottest Month Ever Measured on Earth

From Gavin Schmidt at NASA on Twitter this afternoon: Every month in 2016 has set a new record in the NASA data, but July 2016 was not just a record for July, it was the hottest month recorded. NOAA data comes out later this week (They do an independent analyses). Raw data is here: GLOBAL Land-Ocean Temperature Index in 0.01 degrees Celsius base period: 1951-1980 sources: GHCN-v3 1880-07/2016 + SST: …

Catastrophic Flood Event Underway In Louisiana

Catastrophic Flood Event Underway In Louisiana

Thousands of people have been rescued, and thousands of others are trapped by flood waters in Louisiana tonight, as over 20 inches of rain fell starting early Friday and through the weekend. I’m going to post various images/data to put some context into what/why this is happening. These floods are not yet over, and the threat is now increasing in parts of Missouri and Illinois, where up to 6 inches …

Brutal Heat For the Eastern Seaboard This Weekend.

Brutal Heat For the Eastern Seaboard This Weekend.

A weekend of brutal heat is on the way, from here on Delmarva, to DC, and all the way to New York, with heat index values well above 100. Extreme humidity covers much of the Eastern half of the U.S. this Friday evening, and the high moisture content of the air is pushing heat index values into the danger range. The levels of water vapor in the atmosphere are also …
