Is global warming killing bees?

Study finds 15 common bee species suffer as temps rise

The urban heat island effect isn’t just bad for people — it’s also harming bees, according to a new study from North Carolina State University.

“We looked at 15 of the most common bee species in southeastern cities and – through fieldwork and labwork – found that increasing temperatures in urban heat islands will have a negative effect on almost all of them,” said associate entomology professor Steve Frank.

Sunday set: Wildflower love

Alpine beauties

Some wildflower love from Austria spanning the last couple of months, from first sprouts emerging through the remnant muck of winter, to forest orchids. Check out the Summit Voice photo archives for more wildflower shots from around the world, and visit our online gallery to purchase fine art nature and landscape prints.

Many wildflower species are under the gun from climate change, especially in the mountains, where they will be pushed out of their habitat. Other studies have documented how global warming will affect native plant diversity in California. The changes to plant communities will ripple through ecosystems, affecting insect and birds, as many studies have shown.

 

Earth to Pruitt: Paris is still on!

EPA chief continues to alienate important allies

By Bob Berwyn

The U.S. government continues to show how out of tune it is with the rest of the world’s leading economic nations with a press release from the EPA claiming that it has “reset” the conversation about climate change to reflect the Trump administration priorities and the “expectation of the American people.”

Apparently, EPA Administrator didn’t get the clear message from scores of American cities and states that responded to Trump’s withdrawal from the Paris climate agreement by forming a sub-national coalition that is aiming to uphold the goals of that agreement. The We Are Still In Group also includes hundreds of counties, universities and businesses committed to the agreement, so all Pruitt is managing to do is to divide the country.

Pesticides impair honey bee flying abilities

Nonlethal exposure has significant impacts, new study shows

Staff Report

The evidence keeps mounting that pesticides are the main driver of honey bee declines. In a new study, scientists with the University of California San Diego showed that a commonly used neonicotinoid pesticide (thiamethoxam) can significantly impair the ability of otherwise healthy honey bees to fly, raising concerns about how pesticides affect their capacity to pollinate and the long-term effects on the health of honey bee colonies.

Previous research has shown that foraging honey bees that ingested neonicotinoid pesticides, crop insecticides that are commonly used in agriculture, were less likely to return to their home nest, leading to a decrease in foragers. Continue reading “Pesticides impair honey bee flying abilities”

Seismic blasting once again threatens East Coast environment

Defying local communities, Trump seeks to open area for oil drilling

Staff Report

In the bizarro alt-reality universe of Trumpistan, there’s nothing like celebrating the world’s oceans by opening them up for oil drilling — and that’s just what the oil-stained kleptocrat wants to do by authorizing five companies to search for oil off the Atlantic Coast — from Florida to Delaware — using loud seismic airgun blasts that hurt whales, dolphins and other animals. The exploration activities are the first step to opening the Atlantic to new oil drilling.

The move comes even as communities up and down the Atlantic Seaboard have said loud and clear they are not interested. Nearly 100 municipalities from New Jersey to Florida have adopted resolutions rejecting seismic blasting off the East Coast. And more than 40,000 local businesses and business associations have publicly opposed it, citing threats to marine life and local economies.

Sunday set: The Paris climate agreement won’t die

Dont’t despair — act and vote!


The president’s decision to start pulling the U.S. out of the Paris climate agreement was bitter disappointment for many, but it’s important to remember that the signing of the accord wasn’t an end. It marked the beginning of a long and difficult path that was sure to be fraught with challenges along the way. It was also designed to withstand major shocks, including the pull-out of a major signatory like the U.S. After all, this isn’t the first time it happened. The U.S. also failed to follow through on the Kyoto climate protocol. Read about how the Paris agreement was designed with this history in mind in one of my recent stories for Pacific Standard.

It’s also worth remembering that it will take several years for the withdrawal. In fact, the process won’t be complete until the day after the next U.S. presidential election, so perhaps his wrong-headed move can galvanize climate activists to focus on what matters — electing a candidate who will not only stay involved in global climate policy, but who will act decisively on the domestic front and fight for the changes needed in energy policy and many other areas so that the U.S. can actually deliver on climate action.

To me, Trump’s Paris speech was dangerous beyond climate policy. The language he used to justify his decision sounded a lot like the language Hitler used in the 1930 to rally support for his nationalist policies, and Trump’s attack on global cooperation could end up going far beyond climate. Read more on this topic here.

There’s a lot at stake, especially for the countries that can least afford to deal with global warming impacts. During the most recent climate talks in Bonn, the group of most vulnerable countries made it clear that it is a matter of survival. I reported on their concerns here.

And yes, there is reason to be hopeful. While Trump pursues unrealistic goals of dialing back U.S. policy to the age of coal, most other countries, especially India and China, are racing ahead. Their investments in renewable energy are very likely to drive the shape of global energy markets in the coming decades. More here.

Bat-killing white-nose syndrome found in Alabama cave

Inexorable spread of deadly disease continues

Staff Report

The deadly fungal white-nose syndrome has been detected in a new species of bat in the southeastern U.S. for the first time.

Following winter surveys, the bat-killing disease was found in the southeastern Myotis. To date, nice species of hibernating bats have been identified as susceptible to the disease.

The diseased bat was found in Shelby County, Alabama, at Lake Purdy Corkscrew Cave, owned by the Birmingham Water Works and managed by the Southeastern Cave Conservancy, Inc., a nonprofit organization dedicated to cave acquisition, conservation and management. WNS in the southeastern bat was confirmed in the laboratory by the U.S. Geological Survey.

A fungus, Pseudogymnoascus destructans, or Pd, causes WNS, which affects many, but not all bat species that come into contact with it. Of those affected, bat populations have declined by more than 90 percent. Continue reading “Bat-killing white-nose syndrome found in Alabama cave”
