Why the Migrant Caravan Story Is a Climate Change Story

Why the Migrant Caravan Story Is a Climate Change StoryDrought, crop failure, storms, and land disputes pit the rich against the poor, and Central America is ground zero for climate change. Guatemala, Honduras, and El Salvador lie in the trajectory of the so-called “dry corridor” of Central America that stretches from Southern Mexico to Panama. This epithet is a recently adopted description of the region, to describe the droughts that have risen in intensity and frequency over the last 10 years.

From German Trains To South Korean Buses, Hydrogen Fuel Is Back In The Energy Picture

From German Trains To South Korean Buses, Hydrogen Fuel Is Back In The Energy Picture
As the price of renewable energy drops and storage technologies mature, hydrogen fuel is drawing fresh attention. Perhaps, finally, hydrogen’s moment has arrived. Japan is planning to use the 2020 Tokyo Olympic Games to showcase its vision for a hydrogen society and has invested US$348 million in establishing hydrogen refueling stations and other infrastructure. Germany has launched the world’s first hydrogen-powered trains...

Are We Are Heading For A New Cretaceous Period, Not For A New Normal

Are We Are Heading For A New Cretaceous Period, Not For A New Normal
A lazy buzz phrase – ‘Is this the new normal?’ – has been doing the rounds as extreme climate events have been piling up over the past year. To which the riposte should be: it’s worse than that – we’re on the road to even more frequent, more extreme events than we saw this year.

The Un-united States Of America Part 2: The Storm Before The Storm

The Un-united States Of America Part 2: The Storm Before The Storm

I was recently sent a slick piece of fossil-fuel-propaganda that was mostly full of half-truths to tell a lie. If nothing else, it does make one listen to arguments on possible needed limits to free speech. However, limiting access for venues of speech is a slippery slope, but so is damaging the public with untruths. Is it OK to tell lies for financial gain that harms the public?

How Climate Change Could Cause A Global Beer Shortage

How Climate Change Could Cause A Global Beer Shortage

Cultural Heritage Has A Lot To Teach Us About Climate Change

Cultural Heritage Has A Lot To Teach Us About Climate Change
Museums, archaeological sites and historical buildings are rarely included in conversations about climate change, which tend to focus on the wider impact and global threats to our contemporary world. Yet these threats impact everything, from local cultural practices to iconic sites of outstanding universal value. In light of this, it’s worth exploring the relationship between our heritage and the changing global climate in more detail.

Contrary to stereotypes of young generations being narcissistic or complacent, researchers say both groups are united in concerns about the future of the environment.

Rogue Hurricanes That Head Northwards May Be New Normal

Rogue Hurricanes That Head Northwards May Be New NormalShortly after Hurricane Helene formed off the coast of West Africa on September 7, it did something unusual. Instead of following most hurricanes westward across the Atlantic, Helene turned north towards the UK and Ireland. Now downgraded to an “ex-hurricane”, Storm Helene is nonetheless expected to bring strong winds across much of England and Wales when it hits on September 17.

Extreme Weather In Europe Linked To Less Sea Ice And Warming In The Barents Sea

Extreme Weather In Europe Linked To Less Sea Ice And Warming In The Barents Sea

The cold, remote Arctic Ocean and its surrounding marginal seas have experienced climate change at a rate not seen at lower latitudes. Warming air, land and sea temperatures, and large declines in seasonal Arctic sea ice cover are all symptoms of the changing Arctic climate. Although these changes are occurring in relatively remote locations, there is growing evidence to link Arctic sea ice retreat to increasingly erratic weather patterns over the northern hemisphere.

5 Ways Communities Are Coping With Climate Anxiety

5 Ways Communities Are Coping With Climate Anxiety
This summer, wildfires erupted in California, torrential rains flooded parts of Japan, and record-breaking temperatures led to a number of heat-related deaths around the globe.

Do Hurricanes Feel The Effects Of Climate Change?
Hurricane Harvey, with its historical amount of rainfall over Texas, followed by a string of Hurricanes Irma, Jose and Katia in the North Atlantic basin in 2017, has triggered longstanding questions about any linkage between hurricanes and climate. Can we really blame these recent hurricanes on climate changes? Or are they simply a coincidence of nature happening once every few decades, similar to the triple of Hurricanes Beulah, Chloe and Doria back in 1967?

Climate Models Predict The World Will Be Anomalously Warm

Climate Models Predict The World Will Be Anomalously Warm Until 2022
We developed a new prediction system we call PROCAST (PROabilistic foreCAST), and used it to predict the natural variability of the climate system. This refers to how the climate varies naturally from warm to cool phases that last a few years at a time, and is separate from the long-term trend of anthropogenic global warming. PROCAST predicts a warm phase for the next few years.

This Solar-Powered Still Can Make Fresh Water From Salty Water

This Solar-Powered Still Can Make Fresh Water From Salty WaterLocal people collect water from a muddy waterhole in 2006 in San Marcos Tlacoyalco. The Tehuacan Valley South-East of Mexico City has long experienced severe water shortages. Drought and climate change have contributed to this but recent industrial growth has also strained the very limited ground water resource. Water resources in the area are largely based on a weekly delivery by truck as well as collecting water from small pools known as Jagueys.
