Melting Glaciers

Most of the world’s frozen water is locked up at the poles. 99 percent of Earth’s land ice is located in the Greenland and Antarctic ice sheets. Yet the remaining ice in the world’s glaciers contributed just as much to sea rise as the two major ice sheets combined from 2003 to 2009, says a new study led by Clark University and involving the University Colorado Boulder. The new research found that all glacial regions lost significant mass from 2003 to 2009, with the biggest ice losses occurring in Arctic Canada, Alaska, coastal Greenland, the southern Andes and the Himalayas. The glaciers outside of the Greenland and Antarctic sheets lost an average of roughly 260 billion metric tons of ice annually during the study period, causing the oceans to rise 0.03 inches, or about 0.7 millimeters per year.

Leonardo DiCaprio’s environmental charity auction at Christie’s in New York has raised an impressive $33.3 million from wealthy art collectors. Most of the sale proceeds went to environmental protection causes promoted by the Leonardo DiCaprio Foundation. The Hollywood actor, who was himself present at the auction, urged collectors to bid as if the planet’s fate “depends on us” – and they responded to his call generously.

Tundra Carbon Impact?

There is a concern with the carbon stored in the form of frozen partially decomposed vegetation in the vast tundra of the north. When the permafrost melts, it may releases carbon in the form of carbon dioxide and methane, both of which are greenhouse gases. The amount of greenhouse gases which will be released from the Arctic’s stockpile of carbon may be more secure than scientists thought. In a 20-year experiment that warmed patches of chilly ground, tundra soil kept its stored carbon, researchers report. Almost half of the world’s soil carbon is stored at high latitude, in the form of dead and decaying organisms.

Eat Insects To Mitigate Deforestation and Climate Change

A new 200-page-reportby the UN Food and Agriculture Organization (FAO) urges human society to utilize an often-ignored, protein-rich, and ubiquitous food source: insects. While many in the industrialized west might turn up their noses at the idea of eating insects, already around 2 billion people worldwide eat over 1,900 species of insect, according to the FAO. Expanding insect-eating, the authors argue, may be one way to combat rising food needs, environmental degradation, and climate change.

CO2 Levels Top 400 ppm at Hawaii Monitoring Station

CO2 levels have been increasing relatively steadily for more than 50 years.

On May 9, the daily mean concentration of carbon dioxide in the atmosphere of Mauna Loa, Hawaii, surpassed 400 parts per million (ppm) for the first time since measurements began in 1958. Independent measurements made by both NOAA and the Scripps Institution of Oceanography have been approaching this level during the past week. It marks an important milestone because Mauna Loa, as the oldest continuous carbon dioxide (CO2) measurement station in the world, is the primary global benchmark site for monitoring the increase of this potent heat-trapping gas.

Watery Moon

The dark regions on the Moon were once considered seas full of water. Well that is not true but there is some water on the Moon. Researchers used a multicollector ion microprobe to study hydrogen-deuterium ratios in lunar rock and on Earth. Their conclusion: The Moon’s water did not come from comets but was already present on Earth 4.5 billion years ago, when a giant collision sent material from Earth to form the Moon.

Global greenhouse gas emissions from the agricultural sector totaled 4.69 billion tons of carbon dioxide (CO2) equivalent in 2010 (the most recent year for which data are available), an increase of 13 percent over 1990 emissions. By comparison, global CO2 emissions from transport totaled 6.76 billion tons that year, and emissions from electricity and heat production reached 12.48 billion tons, according to Worldwatch Institute’s Vital Signs Online service.

Bright Clouds with Added Pollution

Posted by admin | Posted in Environmental News | Posted on 07-05-2013

University of Manchester scientists, writing in the journal Nature Geoscience, have shown that some natural emissions and man made pollutants can have an unexpected cooling effect on the world’s climate by making clouds brighter. Clouds are made of water droplets, condensed on to tiny particles suspended in the air. When the air is humid enough, the particles swell into larger cloud droplets. It has been known for some decades that the number of these particles and their size control how bright the clouds appear from the top, which affects the the efficiency with which clouds scatter sunlight back into space. A major challenge for climate science is to understand and quantify these effects which have a major impact in polluted regions of the world.

Robot Flies

Science often imitates life. Insects are common in the world. Tiny critters crawling and flying about. Now we are genuinely making them. In the very early hours of the morning, in a Harvard robotics laboratory last summer, an insect took flight. Half the size of a paperclip, weighing less than a tenth of a gram, it jumped up a few inches, hovered for a moment on fragile, flapping wings, and then sped along a preset route through the air. It was not science fiction, it was a man made fly.

Atlantic Cup Race Now Carbon-Neutral

Posted by admin | Posted in Environmental News | Posted on 03-05-2013

The 2013 Atlantic Cup presented by 11th Hour Racing has announced its final plans and competition field for the third annual running of the premier Class 40 sailing event in the country. The event will feature seven boats; six from the USA and one from Great Britain, with race organizers once again making a strong commitment to eco-friendly sailing. Last year, in partnership with 11th Hour Racing and Green Mountain Energy Company, the Atlantic Cup became the first carbon-neutral sailing race in the USA by offsetting an estimated 23,030 pounds (10.45 metric tons) of CO2 from entering the atmosphere. Sailors for the Sea (SfS) certified the event Gold in 2012, with SfS unveiling a new Platinum level certification in 2013 that the Atlantic Cup will strive for.
