Paris climate agreement seen as turning point by UN
January 30, 2016 08:06 AM - United Nations News Centre
Less than two months after 196 parties to the United Nations Framework Convention on Climate Change (UNFCCC) adopted the Paris Agreement, the global community is already seeing signs of it being a decisive turning point, according to a senior UN official dealing with climate issues.
A month and a half since 196 parties to the United Nations Framework Convention on Climate Change (UNFCCC) adopted the Paris Agreement, the global community is already seeing signs of it being a decisive turning point, according to a senior UN official dealing with climate issues.
“Much has been happening since Paris – the World Meteorological Organization (WMO) confirmed that 2015 was the hottest year on record, not just by a little but by a lot,” Janos Pasztor, who was today appointed as Senior Adviser to the Secretary-General on Climate Change, told reporters at a briefing in New York.
Meat consumption and climate change linked by EU study
January 28, 2016 07:22 AM - Sarantis Michalopoulos, EurActiv
The overconsumption of meat will inevitably push global temperatures to dangerous levels, a recent study has warned, urging reluctant governments to take action.
The world's rapidly expanding population is posing a huge challenge to farmers. A reportpublished in November 2015 by Chatham House, and the Glasgow University Media Group, examined the interconnection between meat and dairy consumption with climate change.
Nearly one-third of the world's cultivated land is being used to grow animal feed. In the EU alone, 45% of wheat production is used for this purpose, with 30% of overall use met by imports.
Why aren't the endangered western gray whales recovering from over hunting?
January 27, 2016 06:38 AM - Oregon State Universtity
The eastern gray whales that commonly appear along the West Coast of the United States seemingly have recovered from over-hunting with new protective guidelines established in the 1970s. Their counterparts across the ocean – western gray whales – have not fared as well.
Some scientists believe that a lack of prey may be a limiting factor in the recovery of western gray whales, which number fewer than 200 in their feeding area near Russia’s Sakhalin Island. For years, researchers were unable to assess the growth of whale prey in the region because of the remote location, inaccessible conditions of winter ice cover, and the rugged weather that prevented winter sampling.
However, researchers from Russia and the United States studied an inch-long crustacean, Ampelisca eschrichtii, an amphipod that is a favorite food of the western gray whale, in samples that were collected from the Sakhalin Shelf between late spring and early fall over six years between 2002 and 2013. The research team found enough information in the limited samples to assess the missing winter-life history of these amphipods and to document their great abundance and production.
Buzzards Bay being impacted by climate change
January 22, 2016 02:44 PM - Woods Hole Oceanographic Institution
An analysis of long-term, water quality monitoring data reveals that climate change is already having an impact on ecosystems in the coastal waters of Buzzards Bay, Mass. The impacts relate to how nitrogen pollution affects coastal ecosystems.
Utilizing 22 years of data collected by a network of citizen scientists, researchers from the Woods Hole Oceanographic Institution (WHOI) and their colleagues at the Buzzards Bay National Estuary Program, the Buzzards Bay Coalition, and the Marine Biological Laboratory found that average summertime temperatures in embayments throughout Buzzards Bay warmed by almost 2 degrees Celsius—roughly 4 degrees Fahrenheit.
"That is a rapid temperature increase for marine life," said Jennie Rheuban, a research associate at WHOI and lead author of the paper published January 15, 2016, in the journal Biogeosciences. "For some species, a single degree Fahrenheit change can mean the difference between a comfortable environment and one where they can no longer thrive."
Does eating less meat lead to decreased Greenhouse Gas emissions?
January 19, 2016 10:06 AM - Universtiy of Edinburgh
Reduced meat consumption might not lower greenhouse gas emissions from a major beef producing region, research shows.
The finding may seem incongruous, as intensive agriculture is responsible for such a large proportion of global emissions.
According to research by University researchers, Scotland’s Rural College and Brazilian Agricultural Research Corporation, reducing beef production in the Brazilian Cerrado could increase global greenhouse gas emissions.
To clean up ocean plastics focus on coasts, not the Great Pacific garbage patch
January 19, 2016 07:14 AM - Imperial College London via EurekAlert!
The most efficient way to clean up ocean plastics and avoid harming ecosystems is to place plastic collectors near coasts, according to a new study.
Plastic floating in the oceans is a widespread and increasing problem. Plastics including bags, bottle caps and plastic fibres from synthetic clothes wash out into the oceans from urban rivers, sewers and waste deposits.
How to make your new house a sustainable one
January 18, 2016 11:24 AM - Ewa Gromadzka
People might falsely believe that when they are building a house incorporating any sustainable solutions require additional costs and effort. It is actually the opposite. Some of the sustainable solutions require very little in any financing with comparison to the costs that need to be incurred anyways in a newly constructed building. Moreover, while an initial cost might be a bit higher as for purchasing, for example a sustainable heating system, there is a fast return on investment as utility bills are much lowers with sustainable heating than a standard one. It is possible to save around 30% on the use of energy and water in a sustainable house. That is a case with any other sustainable solution, when it pays off to invest in environment friendly solution in every case.
Below there is list of sustainable solutions that can be applied in every house.
- Heat recovery system for the ventilation, heating and cooling.
- The use of geothermal heat pump for heating the house, allows for great savings on heating costs.
- It is common to use only floor heating as a heating option in energy efficient houses (no radiators).
- Use of low energy doors and windows (recommended triple glazed windows).
Denmark breaks its own world record in wind energy
January 15, 2016 07:04 AM - EurActiv
Danish wind turbines set a new world record in 2015. Wind power is now counted for 42.1% of the total electricity consumption in Denmark, according to data published on Friday (15 January).
The percentage of wind power in Denmark's overall electricity mix is the highest in the world. Last year, the share was 39.1%, which was a record, according to Energinet, which runs the power grids.
Recycling on the ropes, France has a plan to fix the industry
January 11, 2016 05:29 AM - EurActiv
Low raw material costs have dealt a heavy blow to the recycling industry. The French recycling federation (FEDEREC) believes the sector needs a complete overhaul to stay afloat in the coming years.
FEDEREC published its view of the future of recycling in a white paper entitled "The recycling industry by 2030." In the preface to this 70-page document, a frank discussion of the problems facing the industry and how they might be solved, Corinne Lepage, a Republican politician, evoked a sector "devastated by an oil price that is so low that it is driving us back towards a linear economy, as it is cheaper today to buy primary raw materials than recycled raw materials".
Natural carbon sinks and their role in climate
January 10, 2016 11:32 AM - Mark Dwortzan | MIT Joint Program on the Science and Policy of Global Change
Protected areas such as rainforests occupy more than one-tenth of the Earth’s landscape, and provide invaluable ecosystem services, from erosion control to pollination to biodiversity preservation. They also draw heat-trapping carbon dioxide (CO2) from the atmosphere and store it in plants and soil through photosynthesis, yielding a net cooling effect on the planet.
Determining the role protected areas play as carbon sinks — now and in decades to come — is a topic of intense interest to the climate-policy community as it seeks science-based strategies to mitigate climate change. Toward that end, a study in the journal Ambioestimates for the first time the amount of CO2 sequestered by protected areas, both at present and throughout the 21st century as projected under various climate and land-use scenarios.
