The Devil In The Climate Change Details

  Greenland is melting, the oceans are warming, the sea is rising (and becoming more acidic), and the Arctic sea ice is in a serious decline (that seems to be faster than predicted). These are all things that those who work in climate science understand and accept. They also accept that they are almost certainly being caused by rising greenhouse gases in our atmosphere. Yes, large portions of the public may not …

Answers To The Climate Questions TV Meteorologists Get Asked The Most

My good friend Meteorologist Paul Gross, at WDIV-TV in Detroit, decided to do something very few on air weathercasters have done: he directly addressed climate change in a station webcast. Paul was my predecessor as chairman of the AMS Committee on Station Science (he actually started the committee), and he and I care deeply about using our positions to give viewers accurate science information. Many on air weathercasters shy away …

Andy Revkin in Audubon Is Well Worth A Read

The Audubon Society has released a well done report about climate change. Part of their report is a great piece by NY Times Dot Earth blogger Andy Revkin (Click the image below to read it). One thing worth noting however, and that is that you might be the idea from it that we can continue as we are for 49 years and still be ok. We almost certainly cannot, because …

97 Scientists Attempt To Dispel The Greatest Scientific Myth in 97 Hours

The biggest scientific myth of today is that the science community is divided about the threat to our climate from burning fossil fuels. It is simply not true, and if you were to read the different scientific journals, you would quickly see that the consensus is overwhelming. Progress is being made, and those who refuse to accept it are increasingly being seen as out of touch with reality. The media …

Who Really Declared War on Coal

Have you seen those slick adverts about clean coal on cable TV lately? They seem to have disappeared, but I may be just missing them. If you live in the UK, you won’t be seeing them on British TV, because they’ve been banned by regulators there as misleading, and that’s the kind way of putting it. Bald faced lie is IMHO more accurate. (Here in America, you can get away …

How Hot Is Your City?

You’ve probably heard about the urban heat island effect, but I bet you do not realize is how much it affects your weather (and how much it costs you in cooling costs). The folks at Climate Central put out a report this month that breaks down how large the temperature differences are between some cities, and the rural areas surrounding them. The report makes it obvious that we are paying a …

Heating up the fishbowl: Climate change threatens endangered Devils Hole pupfish

Climate change is hurting reproduction of the critically endangered Devils Hole pupfish, threatening the survival of the already small population, new research shows.

July Heat and Misleading Headlines

This past July was the 4th hottest on record and for the 38th July in a row, the global temperature in July was above the average July temperature in the 20th century. Not only that but the same thing has happened for the last 358 consecutive months, and that’s pretty amazing when you think about it. You may have seen some headlines this week about a “global warming pause” that …

Sea-level spikes can harm beaches worse than hurricane

Unforeseen, short-term increases in sea level caused by strong winds, pressure changes and fluctuating ocean currents can cause more damage to beaches on the East Coast over the course of a year than a powerful hurricane making landfall, according to a new study. The new research suggests that these sea-level anomalies could be more of a threat to coastal homes and businesses than previously thought, and could become higher and more frequent as a result of climate change.

Taking The Planets Temperature Is Best Done In Ocean

Your filling the backyard pool for summer, and the kids are asking how long it will take to fill up. Now, you could just use simple math (using the gallons per minute you are adding to the pool divided by the total volume) and get an answer, but lets say you forgot to ask what it was and the internet is down, so you can’t look it up. Well, you …

NOAA: Earth Had Its Hottest June On Record

From NOAA: “The globally averaged temperature over land and ocean surfaces for June 2014 was the highest for June since record keeping began in 1880. It also marked the 38th consecutive June and 352nd consecutive month with a global temperature above the 20th century average. The last below-average global temperature for June was in 1976 and the last below-average global temperature for any month was February 1985. “ FYI May …

Canada Wildfire Smoke Edging Southward

  In the Boreal forests of Canada there have been huge wildfires this month and the smoke is covering much of Canada. Late images this afternoon show the smoke is moving across the Great Lakes states as well, and it may move into the northeast U.S. soon. This part of the world has warmed more than any other over the past 60 years, and Climate Central has a nice write-up …

Australian Drought Is Likely Result of Rising Greenhouse Gases

A new paper in Nature Geoscience has found that the increasing drought in Australia is very likely due to rising greenhouse gases, and dropping levels of stratospheric Ozone in the atmosphere, and NOT a normal climate fluctuation. Model data also showed that it will likely get worse as greenhouse gases increase over the next century. Key Findings (from GFDL release-see link below) An important new tool for prediction of regional-scale …

Global climate models fail to simulate key dust characteristics

Climate models that simulate the airborne African dust that influences Atlantic Ocean hurricanes are not up to the task of accurately representing the characteristics of that dust.

In a new study, researchers led by Amato Evan, a climate scientist at Scripps Institution of Oceanography, UC San Diego, examined the performance of 23 state-of-the-art global climate models used in the Fifth Assessment Report of the Intergovernmental Panel on Climate Change. The researchers found that none of them yielded accurate data on dust characteristics.

Indefensible Ignorance

I spotted this online today, and believe me it is being shared far and wide in science circles. A statement like this from a 5th grader would be alarming, but from someone (State Senator Brandon Smith) who makes laws is downright frightening. What is more frightening is that the science literacy of his constituency is so low, he’ll likely be easily re elected. In case there are any doubts I …

Livestock digestion released more methane than oil and gas industry in 2004

Livestock were the single largest source of methane gas emissions in the United States in 2004, releasing 70 percent more of the powerful greenhouse gas into the atmosphere than the oil and gas industry, according to a new study.

The new study based on satellite data from 2004 provides the clearest picture yet of methane emissions over the entire U.S. It shows human activities released more of the gas into the atmosphere than previously thought and the sources of these emissions could be much different than government estimates.

Cold War era samples reveal sharp drop in major global warming agent in part of Arctic

Scientists measuring soot on thousands of air filters from the Finnish Arctic found a 78 percent decrease in the particulates — the second largest man-made contributor to global warming — from 1971 to 2010, according to a new study.

NCDC: Hottest May On Record

  The National Park Service had an interesting post on FLIKR today (as well with this image): FROM NPS: Shrinking Snowpacks A recent snowstorm brought nearly 3 feet of snow near Logan Pass in Glacier National Park, and road crews are still working hard on opening the Going-to-the-Sun Road. Large June snowstorms like this one used to be more common in the northern Rockies, but average snowpacks have been in …

The risky business of climate change

Up to $106 billion worth of coastal homes and businesses in the U.S. are likely to be underwater by the year 2050 due to rising sea levels, and up to $507 billion in coastal property will likely be below sea level by 2100, according to a new report released today. The report is based in part on a new study on sea level rise in Earth’s Future, a journal of the American Geophysical Union.
