• West Antarctica snow accumulation increased in the 20th century

    Annual snow accumulation on West Antarctica’s coastal ice sheet increased dramatically during the 20th century, according to a new study published today (Wednesday 4 November) in the American Geophysical Union journal Geophysical Research Letters. The last three decades saw more snow build up on the ice sheet than at any other time in the last 300 years.

    The research gives scientists new insight into Antarctica’s ice sheet. Understanding how the ice sheet grows and shrinks over time enhances scientists’ understanding of the processes that impact global sea levels.

    The new study used ice cores to estimate annual snow accumulation from 1712 to 2010 along the coastal West Antarctic. Until 1899, annual snow accumulation remained steady, averaging 33 and 40 centimeters (13 and 16 inches) water, or melted snow, each year at two locations.

  • Southern Ocean ecosystems acidifying

    As a result of increasing atmospheric carbon dioxide concentrations, the chemistry of the Southern Ocean is expected to change so fast over the next few decades that tiny creatures at the base of the food web may soon struggle to form their shells. New research by scientists from UH Mānoa and the University of Alaska, Fairbanks (UAF) finds that, for some organisms, the onset of such critical conditions will be so abrupt, and the duration of events so long, that adaption may become impossible.

    The study, published this week in the journal Nature Climate Change, uses a number of Earth System Models to explore how the uptake of anthropogenic carbon dioxide and the resulting ocean acidification will affect the Southern Ocean over the next century.

  • Should government buildings offer free Electric Vehicle charging?

    As governments around the world continue to push the concept of electric vehicles there are growing calls for all government buildings to offer free EV charging. This would certainly kickstart the concerns regarding EV charging networks which seems to be at the forefront of the minds of many sceptics. So, how would this concept work and is it really viable?

    Helping the electric vehicle industry

    While many governments around the world are doing a significant amount of work behind the scenes to help the electric vehicle market, could they do more? It would be wrong to suggest that all government buildings do not offer any form of electric vehicle charging but for many people these services are few and far between. When you consider that countries such as the UK employ more than 50% of the workforce in public services there must be an enormous scope to assist the industry?

  • Global warming continuing

    Earth has just had the hottest January-September on record, the United Nations World Meteorological Organization (WMO) said today, adding that the average air and sea temperatures in September logged the greatest rise above monthly average in the 136-year historical record.

    According to a press release from WMO, the Global Climate Report from the United States National Oceanic and Atmospheric Administration (NOAA), the globally averaged air temperature over land and sea surface temperature for September was 0.90°C (1.62°F) above the 20th century average temperature. Record warmth was observed across much of South America and parts of Africa, the Middle East, Europe, and Asia.

  • Some Ice Sheets in Greenland slowing their movement

    In the face of decades of increasing temperatures and surface melting, the movement of the southwest portion of the Greenland Ice Sheet that terminates on land has been slowing down, according to a new study being published by the journal Nature on Oct. 29.

    Researchers derived their results by tracking ice sheet movement through Landsat satellite images taken from 1985 to 2014 across a roughly 3,088-square-mile (8000-square-kilometer) region in southwest Greenland. They found that, between 2007 and 2014, ice movement slowed in 84 percent of the study area, during a period of high surface melt, compared to the years between 1985 and 1994. The average slowdown was 12 percent, or 32.8 feet (10 meters) per year.

  • New report addresses how we can slow climate change

    Top environmental researchers from UCLA joined a team of 50 University of California experts in issuing a new report today with solutions to stabilize Earth’s climate this century. 

    The report, Bending the Curve, was released Tuesday at the UC Climate Neutrality Initiative Summit in San Diego, and provides 10 scalable solutions to reduce global greenhouse emissions.

  • Why are diesel cars so popular in Europe?

    An estimated annual 'tax gap' subsidy of some €16 billion for diesel over petrol has made Europe the world's largest market for diesel cars - but the Volkswagen scandal has put the national tax schemes supporting this industry at risk.

    “There is no reason to keep subsidising this sector," Carlos Calvo, policy analyst at Transport & Environment, told EurActiv on Monday (26 October). The efficiency of petrol-fuelled cars has improved significantly in recent years, while the diesel industry has reduced its nitrogen-oxide emissions only very slowly.

  • Waterfalls are more threatened than you might think

    More than 100 years ago today, a 63-year-old Michigan schoolteacher took the first ride ever down Niagara Falls in a barrel. Annie Edson Taylor may have survived, but the future will tell if the waterfalls available for such (now-illegal) escapades will. Here are a few threats to waterfalls we can’t ignore if we want to preserve these natural wonders.

    1. Drought

    Last year, Yosemite Falls went dry for five months. While the falls have always been ephemeral, meaning they flow seasonally, California’s severe drought had stopped them two months earlier than usual in June until December rains started them again a month late. In The Atlantic, outdoorsman and author Michael Lanza wondered if the world’s sixth-highest falls would actually disappear, with climate change leading to less and less snowfall. Snowpack in the Cascade Range has already decreased 15 to 30 percent in the past 70 years.

  • How will rising sea levels impact the Phillippines?

    More than 167,000 hectares of coastland -- about 0.6% of the country's total area -- are projected to go underwater in the Philippines, especially in low-lying island communities, according to research by the University of the Philippines.

    Low-lying countries with an abundance of coastlines are at significant risk from rising sea levels resulting from global warming. According to data by the World Meteorological Organisation, the water levels around the Philippines are rising at a rate almost three times the global average due partly to the influence of the trade winds pushing ocean currents.

    On average, sea levels around the world rise 3.1 centimetres every ten years. Water levels in the Philippines are projected to rise between 7.6 and 10.2 centimetres each decade.

  • The fish that cools off by jumping OUT of the water

    On hot, humid days, you might jump into water to cool down, but for the tiny mangrove rivulus fish, cooling down means jumping out of water, according to a new study from the University of Guelph.

    In the study published today in the journal Biology Letters, the researchers describe how these fish air-chill themselves on solid ground in order to drop their body temperatures. The researchers also found that fish exposed to higher temperatures for a week tolerated warmer water better.

    The fish jump out of the water to escape rising temperatures, said integrative biology professor Pat Wright, senior author of the study.
