NASA studies details of a greening Arctic
June 2, 2016 11:23 AM - NASA/GODDARD SPACE FLIGHT CENTER via EurekAlert!

The northern reaches of North America are getting greener, according to a NASA study that provides the most detailed look yet at plant life across Alaska and Canada. In a changing climate, almost a third of the land cover - much of it Arctic tundra - is looking more like landscapes found in warmer ecosystems.

With 87,000 images taken from Landsat satellites, converted into data that reflects the amount of healthy vegetation on the ground, the researchers found that western Alaska, Quebec and other regions became greener between 1984 and 2012. The new Landsat study further supports previous work that has shown changing vegetation in Arctic and boreal North America.

Who gets to influence the climate negotiations?
June 1, 2016 01:24 PM - Pavlos Georgiadis, Renee Karunungan and Anna Pérez Català, The Ecologist

The influence of fossil fuel corporations was strongly questioned by developing countries in the post-Paris meeting of the climate change negotiations in Bonn last week. Climate Trackers Pavlos Georgiadis, Renee Karunungan and Anna Pérez Català highlight the key issues that were debated. 

A number of developing countries, led by Ecuador, Guatemala and Bolivia are now calling for concrete measures to define how the public policy making process interacts with the private sector in climate change negotiations. What they want is special attention to be given to concerns over potential conflicts of interest between the industry and the implementation of the Paris Agreement.

San Francisco mandates solar on all new buildings 10 stories or less
May 31, 2016 08:59 AM - Contributor, Triple Pundit

Although those who reside outside of San Francisco may not be aware of the fact, mid-April 2016 marked a huge milestone in the advancement of green technology in the city and its mandated usage in all newly-constructed buildings.

The new legislation, unanimously approved by the San Francisco Board of Supervisors on April 19, states that all new buildings with 10 stories or fewer, including all residential and commercial projects, must include a photovoltaic solar panel installation that encompasses 15 percent of the building’s total rooftop. Moreover, the area that is dedicated to the installation must be positioned in full sunlight and free of any shade or obstructions.

 

How did the giraffe get its long neck?
May 27, 2016 06:09 AM - Penn State University

For the first time, the genomes of the giraffe and its closest living relative, the reclusive okapi of the African rainforest, have been sequenced — revealing the first clues about the genetic changes that led to the evolution of the giraffe’s exceptionally long neck and its record-holding ranking as the world’s tallest land species. The research will be published in the scientific journal Nature Communications on May 17, 2016.

“The giraffe’s stature, dominated by its long neck and legs and an overall height that can reach 19 feet (~ 6 m), is an extraordinary feat of evolution that has inspired awe and wonder for at least 8,000 years — as far back as the famous rock carvings at Dabous in the Republic of Niger,” said Douglas Cavener of Penn State, who led the research team with Morris Agaba of the Nelson Mandela African Institute for Science and Technology in Tanzania.

Spring comes sooner to urban heat islands, with potential consequences for wildlife
May 25, 2016 08:21 PM - Jenny Seifert, University of Wisconsin-Madison

With spring now fully sprung, a new study by University of Wisconsin–Madison researchers shows that buds burst earlier in dense urban areas than in their suburban and rural surroundings. This may be music to urban gardeners’ ears, but that tune could be alarming to some native and migratory birds and bugs.

Study shows how air pollution fosters heart disease
May 24, 2016 07:12 PM - Elizabeth Sharpe, University of Washington Health Sciences

Long-term exposure to air pollution has been linked to an increased risk of heart disease, but the biological process has not been understood. A major, decade-long study of thousands of Americans  found that people living in areas with more outdoor pollution —even at lower levels common in the United States — accumulate deposits in the arteries that supply the heart faster than do people living in less polluted areas.  The study was published May 24 online in The Lancet.

Squid populations on the rise
May 24, 2016 07:09 AM - University of Adelaide

Unlike the declining populations of many fish species, the number of cephalopods (octopus, cuttlefish and squid) has increased in the world's oceans over the past 60 years, a University of Adelaide study has found.

The international team, led by researchers from the University's Environment Institute, compiled a global database of cephalopod catch rates to investigate long-term trends in abundance, published in Cell Press journal Current Biology.

UN Climate negotiations update - how to raise and allocate $100 billion
May 23, 2016 07:15 AM - Georgiadis Pavlos, The Ecologist

The UN intersessional negotiations on climate change (UNFCCC) which started in Bonn last week enter their second week with the big question - how to find and allocate by 2020 the $100bn as agreed in the Paris Agreement. Delegate Pavlos Georgiadis reports.

The burning question for week two of these negotiations is how to raise and allocate the $100bn agreed as part of the Paris Agreement

The first week of the negotiations started slowly, and ended even slower. Negotiators look like they still have some sort of bad hangover, thanks to the fact they are still celebrating the Paris agreement. And while discussions take place inside the UN building in Bonn, Sri Lanka tries to recover from the worst floods in its historyIndia reports the hottest day every recorded in the countryand Carbon Brief warn that we only have five years until the 1,5°C carbon budget is blown.

Increased vegetation in the Arctic region may counteract global warming
May 19, 2016 07:19 AM - Lund University via AlphaGalileo

Climate change creates more shrub vegetation in barren, arctic ecosystems. A study at Lund University in Sweden shows that organisms, such as bacteria and fungi, are triggered to break down particularly nutritious dead parts of shrubbery. Meanwhile, the total amount of decomposition is reducing. This could have an inhibiting effect on global warming.
