As Arctic Ocean Ice Disappears,
Global Climate Impacts Intensify

by peter wadhams
The top of the world is turning from white to blue in summer as the ice that has long covered the north polar seas melts away. This monumental change is triggering a cascade of effects that will amplify global warming and could destabilize the global climate system.

In Fukushima, A Bitter Legacy
Of Radiation, Trauma and Fear

Five years after the nuclear power plant meltdown, a journey through the Fukushima evacuation zone reveals some high levels of radiation and an overriding sense of fear. For many, the psychological damage is far more profound than the health effects.

Confronts Its Radioactive Past

The Rocky Flats Plant outside Denver was a key U.S. nuclear facility during the Cold War. Now, following a $7 billion cleanup, the government is preparing to open a wildlife refuge on the site to the public, amid warnings from some scientists that residual plutonium may still pose serious health risks.

Pressure Mounts to Reform Our
Throwaway Clothing Culture

by marc gunther
Americans dispose of about 12.8 million tons of textiles annually — 80 pounds for each man, woman, and child. In the U.S. and around the world, a growing number of environmentalists and clothing industry executives say it’s time to end the wasteful clothing culture and begin making new apparel out of old items on a large scale.

What’s Killing the Native Birds in
The Mountain Forests of Kauai?

The few remaining species of native forest birds left on the Hawaiian island of Kauai have suffered population declines so severe — 98 percent in one case — that some are near extinction.
Eben Paxton

Eben Paxton
The cause of the collapse, according to a recent study in the journal Science Advances, is not alien plants or predators, but rather warming temperatures that have enabled non-native mosquitoes carrying deadly avian malaria to invade the birds’ high-elevation strongholds. In an interview with Yale Environment 360, Eben Paxton, an avian ecologist with the U.S. Geological Survey and the study’s lead author, says his group’s research showed that the mosquitoes moved into the Alakai Plateau over the last decade, infecting the birds and pushing their populations to a tipping point. He cites a number of approaches for eradicating the mosquitoes, including releasing irradiated infertile males and using genetically modified mosquitoes. “The way that we view Kauai,” he says, “is that it's an early warning system for the rest of the islands.”

26 Sep 2016: Elephants in Africa Suffer Large
Declines as Poaching Worsens in the Region

Elephant populations in Africa fell about 20 percent between 2006 and 2015 — the worst decline in a quarter-century, according to a

An African elephant.
new report by the International Union for Conservation of Nature (IUCN). The continent’s elephant population dropped by 111,000 individuals over the last decade. The IUCN said a recent surge in poaching for ivory, which it called “the worst that Africa has experienced since the 1970s and 1980s,” is largely to blame for the decline. East Africa, for example, has lost almost 50 percent of its historical elephant population, according to the report. In West Africa, 12 populations of elephants have been completely lost since 2006. “It is shocking, but not surprising that poaching has taken such a dramatic toll on this iconic species,” IUCN director general Inger Andersen said in a statement. The IUCN also named habitat loss as a major contributor to the decline.

 

Clinton vs. Trump: A Sharp Divide
Over Energy and the Environment

Environmental and energy issues have received relatively little attention from the two major-party candidates in the 2016 U.S. presidential campaign. But when Donald Trump and Hillary Clinton have spoken out on these issues, the differences — like just about everything else about this campaign — have been stark. In a chart, Yale Environment 360 compares what Clinton and Trump have said on topics ranging from climate change to coal. See the graphic.

23 Sep 2016: World’s Coffee Supply
Threatened by Climate Change, Report Says

A new report says that climate change could significantly reduce the amount of suitable land on which to grow coffee and lead to an increase in outbreaks of diseases that threaten the crop. The report — released by the Australian non-profit, the Climate Institute — warns that under current emissions scenarios, coffee-growing regions could see a 50 percent drop in the acreage fit to raise coffee plants, which need a precise combination of temperature and precipitation to thrive. Rising temperatures are also likely to lead to an increase in diseases like coffee rust and pests like the coffee berry borer, the report said. Major coffee-producing countries in the “bean belt” — including Colombia, Mexico, Brazil, Ethiopia, and Vietnam — have already become less hospitable because of shifts in weather patterns, the report said. “It’s a severe threat,” said an executive at U.S.-based Peet’s Coffee.

 

Interview: Exploring How and
Why Trees ‘Talk’ to Each Other

Two decades ago, while researching her doctoral thesis, ecologist Suzanne Simard discovered that trees communicate their needs and send each other nutrients via a network of latticed fungi buried in the soil
Suzanne Simard

Suzanne Simard
– in other words, she found, they “talk” to each other. Since then, Simard, now at the University of British Columbia, has pioneered further research into how trees converse, including how these fungal filigrees help trees send warning signals about environmental change, search for kin, and transfer their nutrients to neighboring plants before they die. Simard is now focused on understanding how these vital communication systems, which she compares to neural networks in human brains, could be disrupted by environmental threats, such as climate change, pine beetle infestations, and logging. “These networks will go on,” she told Yale Environment 360. “Whether they're beneficial to native plant species, or exotics, or invader weeds and so on, that remains to be seen.”

21 Sep 2016: Paris Climate Agreement Moves
One Step Closer to Entering Into Force

Thirty-one countries officially joined the Paris climate accords this week at United Nations’ meetings in New York City.

UN secretary general Ban Ki-moon.
The announcements bring the total number of countries joining the Paris Agreement to 60, representing 48 percent of global emissions. Once nations that generate 55 percent of global emissions officially join, the agreement will enter into force within 30 days. The new countries include Brazil, the world’s seventh-largest emitter of carbon dioxide; Argentina; Mexico; and the United Arab Emirates. China and the United States officially joined the agreement earlier this month. UN Secretary General Ban Ki-moon predicted the agreement, created in December last year, would enter into force by the end of this year. “What once seemed impossible now seems inevitable,” Ban said.
