The folks in Boston might feel like they are having a run of bad weather now, but it's nothing like the intense hurricanes, fueled by warmer oceans, that frequently pounded the region during the first millennium, from the peak of the Roman Empire into the height of the Middle Ages, according to a new study.
The rate of global warming that had been predicted in the 1990s did not come to pass. In the 21st century, warming has been significantly slower than all the models had predicted, leading to claims that the models contained systematic errors.

Not so, according to a new analysis, it is just random variation. Jochem Marotzke, Director at the Max Planck Institute for Meteorology in Hamburg, and Piers M. Forster, a professor at the University of Leeds in the UK, did a statistical analysis and found that the models do not generally overestimate man-made climate change and so global warming is still highly likely to reach critical proportions by the end of the century if CO2 emissions are not reduced. 
A new study finds that most climate models may have wiggles that undermine accuracy - but they are likely underestimating the degree of decade-to-decade variability occurring in mean surface temperatures as Earth's atmosphere warms.

The models also provide inconsistent explanations of why this variability occurs in the first place and such discrepancies undermine the models' reliability for projecting the short-term pace as well as the extent of future warming, the study's authors warn.

As such, we shouldn't over-interpret recent temperature trends, no matter what blizzard his New York City and leads to exploitation of climate science to generate media pageviews.
Wildfires send hot flames and smoke high into the air, including black carbon emissions associated with climate change and risk to human health. Unless the United States adapts sensible forest management policies, which means fewer instances of the Department of the Interior and environmental lobbyists conspiring to manipulate science reports, carbon emissions from wildfires in the contiguous U.S. could increase by 50 percent by 2050 and double by 2100.
Researchers have determined that languages with a wide range of tone pitches are more prevalent in regions with high humidity levels while languages with simpler tone pitches are mainly found in drier regions.

They explain this by noting that the vocal folds require a humid environment to produce the right tone. That means climate and weather our voices too.

The asteroid that wiped out the dinosaurs set off an intense heat wave that briefly boiled the Earth’s atmosphere – but it didn’t burn off all the plants.

The 10 warmest years in the instrumental record, with the exception of 1998, have now occurred since 2000, which continues a long-term warming of the planet, according to an analysis of surface temperature measurements by NASA's Goddard Institute of Space Studies in New York.

In a separate analysis of the raw data, NOAA scientists also found 2014 to be the warmest on record. They conclude that 2014 ranks as Earth's warmest since 1880. Since then, Earth's average surface temperature has warmed by about 1.4 degrees Fahrenheit (0.8 degrees Celsius), a trend that is largely driven by the increase in carbon dioxide and other human emissions into the planet's atmosphere. The majority of that warming has occurred in the past three decades.
People love that earthy smell after it rains. It turns out there is a good science reason for it, and it's been captured using high-speed imaging.

Petrichor is the  phenomenon first characterized by Australian scientists as the smell released after a light rain. Now scientists at MIT believe they may have identified the mechanism that releases this aroma, as well as other aerosols, into the environment.

Recent results of a study finds that that sensor changes have significantly biased temperature observations from the Snowpack Telemetry (SNOTEL) station network.
More than 700 SNOTEL sites monitor temperature and snowpack across the mountainous western U.S. SNOTEL provides critical data for water supply forecasts. Researchers often use SNOTEL data to study mountain climate trends and impacts to mountain hydrology and ecology. 

University of Montana and Montana Climate Office researcher Jared Oyler and colleagues applied statistical techniques to account for biases introduced when equipment was switched at SNOTEL sites in the mid-1990s to mid-2000s.

Hydrogen fuel cells may be the best option for powering zero-emission vehicles, Toyota will make them available in the United States in 2015, but those fuel cells require an electrocatalyst -- a platinum surface -- to increase the reaction rate, and the cost of the precious metal makes it hard for hydrogen fuel cells to compete economically with the internal combustion engine.
