Delusions of grandeur in building a low-carbon future

Traditional macroeconomic models provide an unstable foundation for decision-making when planning for a low-carbon future. To maximize our ability to achieve our future energy, climate and economic goals, economic modeling concepts must be improved.

Northeast and Midwest U.S. projected to warm faster than national average

The U.S. Northeast and Midwest will warm quickly in the coming decades compared to national and global averages, reaching established temperature benchmarks sooner than most of the rest of the country, and the world, according to recent research published in PLOS ONE.

Are North Atlantic storm tracks shifting south?

As the Arctic warms, decreasing temperature differences between the Arctic and the lower latitudes may push North Atlantic storm systems south. The factors that influence storm tracks are complicated, however, and the accuracy of models predicting future storm tracks is uncertain. The results of a new study, in which researchers looked at changes in Atlantic storm tracks over the past 4,000 years, could improve the accuracy of predictive models and help Europe prepare for shifting storm patterns.

Tallying temperature drops inside tornadoes

The inside of a strong tornado is an intense place, with wind speeds of more than 450 kilometers per hour and dramatic drops in air pressure and temperature. But due to the dangerous unpredictability of such storms, few real-time measurements have been taken inside actual twisters. In a new study, researchers took a mathematical approach to circumvent the danger and calculate temperature changes inside tornadoes, offering a glimpse into how these violent storms operate.

El Niño gets animated

In the winter of 1997 and 1998, a powerful El Niño pattern in the Pacific Ocean caused billions of dollars in damage from flooding and extreme weather worldwide. Now, a new animation of the event is highlighting the complex feedbacks that conspired to create such a devastating climate cycle.

Coral Reef Roundup: December 2016

With multiple threats facing our coral reefs — from climate change to overfishing — and scientists continually studying the coral reefs beneath the waves, new findings are announced often. Here are a few of the latest updates.

Today's weather forecast: Good with a strong chance of improvement

Weather forecasts have improved significantly — roughly one day per decade — since the first numerical, physics-based computer models were implemented in the 1950s. What is needed to continue improving our forecasts?

Sailors right about sneaky rogue waves

Sailors are notorious for telling tall tales, including legends about monstrous “rogue waves” that appear at sea without warning. Oceanographers have traditionally dismissed such stories because they thought that unusually large waves would be preceded by series of waves of increasing size.

How supervolcanoes are set off

If a supervolcano were to erupt today, its impacts could be catastrophic. Fortunately, no such eruption has occurred during human history. The lack of eyewitness accounts, however, makes it difficult for scientists to understand how supervolcanoes evolve and erupt. Based on a recent modeling, researchers have offered a new hypothesis for how supervolcano eruptions might be triggered by external, rather than internal, forces.

Jelly volcano reveals eruption trigger

What makes a volcano erupt? Over the years, scientists have proposed a litany of potential triggers, but there’s always room for one more. With help from dyed water, a laser and a tank of clear jelly, researchers have proposed a new mechanism that might push loaded volcanoes toward eruption.
