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 …

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.

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 …

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 …

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 …

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 …

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.

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 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.

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.

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 …

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.

I am at the American Meteorological Society’s 42nd Conference on Broadcast Meteorology at Squaw Valley,Ca. We are just outside of Lake Tahoe, and I drove up from Las Vegas, through Death Valley and by Mammoth Lakes. The temperature ranged from 96 in Death Valley to 46 at Mammoth, and when i awoke here in Squaw Valley this morning it was 28 degrees! I thought I’d share some pics of …

By Alexandra Branscombe Originally posted on AGU GeoSpace WASHINGTON, DC – What is hidden within and beneath Arctic ice? Why does winter matter? What is being irretrievably lost as the Arctic changes? These are just some of the emerging questions that scientists are being challenged to answer about the rapidly changing Arctic in a new report, “The Arctic in the Anthropocene: Emerging Research Questions,” released last month by the National …

By Dan Vimont, co-chair, Wisconsin Initiative on Climate Change Impacts (WICC) I am a climate scientist who has spent my career understanding the physics of the climate system, and the impacts of climate variability and climate change. I am a co-chair of the Wisconsin Initiative on Climate Change Impacts (WICCI), an effort to understand and prepare for the impacts of climate change that now includes over 200 individuals around Wisconsin. …

By Kate Gordon, Executive Director, Risky Business Despite massive scientific evidence that climate change will have significant effects on the American economy, the business and finance world is still largely turning a blind eye to climate risk. Former New York City Mayor Michael Bloomberg, former Treasury Secretary Henry Paulson, and Farallon Capital founder Tom Steyer started the Risky Business initiative to change this dynamic and create a new shared understanding …

Some 56 million years ago, a massive pulse of carbon dioxide into the atmosphere sent global temperatures soaring. In the oceans, carbonate sediments dissolved, some organisms went extinct and others evolved.
Scientists have long suspected that ocean acidification caused the crisis—similar to today, as manmade carbon dioxide combines with seawater to change its chemistry. Now, for the first time, scientists have quantified the extent of surface acidification from those ancient days, and the news is not good: the oceans are on track to acidify at least as much as they did then, only at a much faster rate.
