The mild winter weather in New England is bad news for the region's moose.

In northern New England, moose number about 70,000, but changing weather seems to be throwing the balance of nature off-kilter, giving an edge to one of the animal's most dangerous enemies — bloodsucking ticks.

The US military sees climate change as a national security threat. So, it’s finding ways to adapt to global warming, to make the armed forces stronger and more flexible. 

For starters, green technologies such as solar "blankets" and hybrid vehicles have improved operations within the Marine Corps and the Navy, according to Capt. Jim Goudreau, who served as a deputy assistant secretary of the Navy. He spent over two decades in the supply corps and is now the head of climate at Novartis.

When President Donald Trump came into office in January, staff at several government agencies were told not to send out news releases or to communicate by social media, and most mentions of climate change disappeared from government websites.

Changing the message on issues that could affect policy is standard procedure with a change of administration, but many saw this as censorship of government scientists — akin to moves taken in Canada under former Prime Minister Stephen Harper.

In one of its first acts, the Republican-controlled Congress overturned the Department of the Interior’s recent Stream Protection Rule. Coal companies are thrilled about the change, but some mining communities aren't quite so sure about it.  

President Donald Trump's repeal of an anti-corruption rule that required extractive industries — like mining, oil drilling and quarrying — to disclose payments to foreign governments has caused dismay among people who advocate for the poor and for transparency in government.

Scott Pruitt, the new head of the Environmental Protection Agency, has sued the agency more than a dozen times. What does that mean for the future of the EPA and for environmental protections in the US?

As the attorney general of Oklahoma, Pruitt chaired an organization of Republican attorneys general who opposed many EPA rules and regulations. Perhaps most famously, Pruitt led a group of states and companies in the continuing court fight against the Obama administration’s Clean Power Plan — a plan crafted by the agency he now runs.

A group of conservative elder statesman has proposed an ambitious carbon dividend plan that could entice bipartisan support, pay families $2,000 a month and cut greenhouse gas emissions more than Barack Obama’s Clean Power Plan.

President Donald Trump has already taken bold steps to undo the climate agenda of his predecessor. He has announced gag orders and contract holds on the Environmental Protection Agency and the Interior Department, as well as executive orders to expedite completion of the Keystone XL and Dakota Access pipelines.

Ever wondered how long evolution actually takes?

We tend to think of it as an achingly slow process, spanning hundreds, even thousands of years. But scientists studying crested anoles — little lizards native to the forests of Puerto Rico — say that urban-dwelling anoles are adapting to their built environments much more quickly than that.

President Donald Trump’s nomination of Neil Gorsuch to the US Supreme Court has sparked widespread speculation about how the appellate judge might rule on upcoming cases in the court’s docket, including high-stakes cases on environmental issues.

Gorsuch's narrow interpretations of agency powers, as well as his lifelong experience as an outdoorsman, could inform his findings if he is confirmed, but “it’s hard to read him because he has not written that many major environmental cases,” says Vermont Law School Professor Patrick Parenteau.

Only a few dozen grizzly bears with bright yellow coats live in the forbidding Gobi Desert in Mongolia. In a new book, wildlife biologist Doug Chadwick writes about how these unique animals survive and what can be done to better protect them.

Chadwick first found out about the Gobi grizzly (called the mazaalai in Mongolian) almost by accident. He was tracking snow leopards in the mountains of Mongolia, near the border between Russia and Kazakhstan.

On Jan. 18, the US Environmental Protection Agency released its first nationwide biological evaluation of three commonly used pesticides. The report found that all three were harmful to virtually all endangered species in the US.

The disaster of Hurricane Katrina in 2005 made clear how vulnerable New Orleans and the low-lying communities along the Gulf Coast are to fierce storms and surging seas. So, a master plan was devised to shore up defenses and repair the sinking coastline that protects the city. Now, authorities have released an updated $50 billion, 50-year plan that rethinks and bolsters those defenses.

The vaquita, the world’s smallest porpoise, lives only in Mexico’s Gulf of California and is critically endangered, due to illegal fishing. Now, the Center for Biological Diversity plans legal action against the US government for its failure to sanction Mexico for not stopping the poaching of vaquitas.

A report from some of the top minds in environmental policy and economics is recommending a new way of evaluating the "social costs" of carbon pollution to keep up with the best available science.

Obama's hidden, and surprising, fossil fuel legacy

Feb 4, 2017

Investigative reporting by a joint team from The Guardian and the Columbia University School of Journalism reveals that the US Export-Import Bank financed around 70 coal-fired power plants and other fossil fuel energy projects in foreign countries during President Barack Obama's terms in office.

These foreign fossil fuel plants are projected to release about as many tons of global-warming gases as the Obama Clean Power Plan would have saved.

A new analysis of sea surface temperatures from an independent source corroborates updated global warming data released in 2015 by the National Oceanic and Atmospheric Administration.

The results contradict allegations from some Republicans on Capitol Hill that NOAA manipulated its 2015 data to show continuous global warming, since earlier NOAA research had suggested the Earth was experiencing a warming "pause" or hiatus.

For writer and illustrator Rachel Ignotofsky, the idea to profile 50 pioneering female scientists in her recent book, “Women in Science,” was spurred by conversations with educator friends. As they talked about the gender gap in science, technology, engineering and math fields, Ignotofsky realized women aren’t just underrepresented in STEM, itself — the stories about their contributions don't get much play, either.

Coal country is pinning its hopes on Trump

Jan 28, 2017

One of the promises President Donald Trump made on the campaign trail was to reopen coal mines and put miners back to work. The message resonated in Pennsylvania’s coal country and helped Trump win the state last November. Now, people here are watching to see if he’ll keep his promise.

Many of these voters don't expect miracles, but they do want Trump to put coal first, according to some residents in the southwest area of the state.

Cracking the code of influenza

Jan 22, 2017

January’s cold, dry weather in many areas of the United States seems to usher in the perfect conditions for seasonal influenza — in humans. But for birds in Europe and Asia, flu season is already in full swing: An epidemic of the H5N8 flu has broken out among European poultry. In Asia, the H5N6 strain is widespread, and another strain, H7N9, has infected birds and even killed three people.

With nearly 9 million hogs on farms across the state, North Carolina is the country’s second-largest producer, behind Iowa.

For activists Trisha Shrum and Jill Kubit, climate change isn't just an abstract concept. Rather, it has faces and names: Eleanor and Gabriel, their children. And through their time capsule project DearTomorrow, Shrum and Kubit are hoping you’ll connect the planet’s future to your loved ones, too.

2016 is a wrap — and with it, likely the hottest year ever recorded. Temperatures weren’t the only anomaly: Louisiana, for instance, saw floods so severe they should only happen every 1,000 years.

Millennials are the new 'fossil fuel freedom fighters'

A new generation of nature writers is coming of age in America. They are beginning to understand how much of the pristine landscape their parents and grandparents enjoyed is now gone.

High levels of "fine particulate matter" (PM2.5) in the air — such as in haze or smog — can lower the stock market, a research team at Columbia University has found.

When particle pollution rises, the market goes down by small but measurable amounts, says team leader Matthew Neidell, an associate professor at Columbia University.

At the end of November, hundreds of firefighters from all over the country battled the Rock Mountain Fire in North Georgia. Fighting the huge blaze in the tinder dry hills was a tough battle, but when it came time to rest, the firefighters, well-accustomed to makeshift lodgings, were offered an unusual, yet comfortable upgrade: a local Conservative Jewish camp.

With unsustainable fishing affecting about 30 percent of the ocean’s wild fish populations and most of the rest already fished to the limit, aquaculture is playing an ever bigger role in putting fish on the dinner table. 

Today, fish farms are the fastest-growing source of animal protein — on the rise, globally, at about 5 percent a year. 

Some advice for starting your own backyard 'carbon farm'

For visitors to Eric Toensmeier’s home in Holyoke, Massachusetts, the lush, 8-foot banana plant in the front yard is the first indication that something is unusual about his landscaping.

A walk around his stucco-covered house confirms it. In the back garden, about 300 species of perennials are thriving on just one-tenth of an acre: Raspberries, mountain mint, bamboo and bush clover all jostle for space alongside persimmon, chestnut and mulberry trees.

Thomas Friedman's latest book, "Thank You For Being Late: An Optimist’s Guide to Thriving In the Age Of Accelerations," is a manifesto for how to cope with our changing planet.

Right now, three powerful forces — technology, globalization and climate change — are accelerating exponentially — and “one of the hardest things for the human mind to grasp is the power of an exponential,” says the columnist for the New York Times. 

Overfishing, plastic pollution, warming temperatures and other impacts of human activities are changing the oceans — resulting in decreasing populations of everything from tuna to whales to dolphins. But humans are also causing one class of sea life to thrive: jellyfish.
