Green roofs are popular in many European countries.  A green roof is a layer of vegetation planted over a waterproofing system installed on a flat or slightly sloped roof.  Such roofs provide shade, remove heat from the air, and reduce temperatures of the roof surface, reducing energy use in the building and diminishing the urban […]

Armadillos are small mammals known for their unique armor-like shell and their digging habits.  There are 21 species, primarily native to South America.  Some species have expanded northward due to their rapid breeding cycle, adaptability, and reduced number of predators.  Only one species – the nine-banded armadillo – is found in the United States.  In […]

Transportation accounts for nearly a quarter of the direct carbon dioxide emissions coming from burning fuel.  As a result, electrification of transport is one of the major ways we can reduce emissions.  Increasing the number of electric vehicles over time is essential for meeting emissions targets. But electric vehicles have the potential to do more […]

In October, the Global Coral Reef Monitoring Network released the first-ever report collecting global statistics on the world’s corals.  It documents the status of reefs across 12,000 sites in 73 countries over 40 years.  Overall, the news is not good, but there were some bright spots. From 2009 to 2018, the world has lost 14% […]

A new NASA study published in the journal Nature Food looks at the impact of global climate change on food crops.  According to the study, declines in global crop yields are likely to become apparent by 2030 if high greenhouse gas emissions continue. The study used advanced climate and agriculture models to predict the effects […]

Estimates are that about 10 million tons of plastic enter the ocean every year.  This is equivalent to a truckload of plastic being dumped into the sea every minute and the stuff is not easy to keep track of.  Some of it ends up in the  infamous ocean garbage patches.  But overall, researchers only know […]

Over 2.25 billion cups of coffee are consumed in the world each day.  Americans spend $80 billion dollars a year on coffee.  Coffee in grown across 12.5 million largely smallholder farms in more than 50 countries.  In other words, coffee is a big deal. Like many things, coffee is subject to the effects of climate […]

The world is awash in plastic.  Discarded plastic litters our roadways, woodlands, and beaches.  It piles up in landfills.  Plastic enters the oceans by the millions of tons.  And plastic is finding its way even to remote and supposedly pristine parts of the world. A team of researchers has found nanoplastics at the isolated high-altitude […]

Permafrost is frozen soil, rock or sediment that can be as much as a few thousand feet thick.  To qualify as permafrost , the material has to have been at or below the freezing point of water for two or more years.  Most of it is located in high latitudes in the Arctic and Antarctic […]

Along with cookies and carols, the Christmas tree is a quintessential part of the holiday season for many people.  According to the American Christmas Tree Association, approximately 75% of Christmas trees in American homes this year will be artificial.  But are artificial trees really the better option for the planet? The short answer is no.  […]

Researchers from Stanford University have been studying the role of large whales on ocean ecosystems with some surprising results. From 1910 to 1970, people killed about 1.5 million baleen whales in the waters surrounding Antarctica.  The whales were hunted for their blubber, baleen, and meat.  Baleen is the filtering fringe that certain whales use instead […]

Approximately 10% of the land area on Earth is covered by ice.  This includes glaciers, ice caps, and the ice sheets of Antarctica and Greenland.  Nearly 70% of all fresh water on earth is locked away in ice.  If all this land ice were to melt, global sea levels would rise by more than 200 […]

After many years of debates, delays, and controversies, offshore wind is about to expand in a big way in the United States.  The White House has announced the goal to deploy 30 gigawatts of offshore wind – enough to power 90 million homes – along the East Coast seaboard by 2030. In New York State, […]

An international research team led by Nanyang Technological University in Singapore has invented a ‘smart’ window material that controls the transmission of heat without blocking the view through the window.  The technology could help reduce the amount of energy needed to cool and heat buildings. The new material can be the basis of an electrochromic […]

More than a century of fire suppression strategies coupled with climate change has led to wildfires that are much larger and more frequent than those of the past.  A question that arises is what happens to the animals in a region when a massive wildfire sweeps through the landscape? For the most part, we don’t […]
