• Renewable Energy Hit Record Levels in 2015

    A new report confirms that 2015 was a record-breaking year for renewable energy in which 147 Gigawatts of renewable electricity came online.

    That figure represents the largest annual increase ever recorded, and is due in part to the $286 billion invested in renewables. In fact, in 2015 almost twice as much money was spent on renewable energy, like solar and wind power, than fossil fuels like gas-fired power stations — only $130 billion.

    This information comes as part of the Renewables Global Status Report authored by the global renewable energy policy network known as REN21.

  • Tropical Depression 1E dissipates

    Tropical Depression 1E or TD1E didn't get far from the time it was born to the time it weakened to a remnant low pressure area along the southwestern coast of Mexico. NOAA's GOES-West satellite captured an image of it remnant clouds.

  • Operation IceBridge completes 2016 Arctic spring campaign

    Operation IceBridge, NASA's airborne survey of polar ice, ended its eighth spring Arctic campaign on May 21. During their five weeks of operations, mission scientists carried out six research flights over sea ice and ten over land ice.

    "We collected data over key portions of the Greenland Ice Sheet, like the fast-changing Zachariae Isstrom Glacier, and we got the broad geographic coverage of Arctic sea ice we needed," said Nathan Kurtz, IceBridge's project scientist and a sea ice researcher at NASA's Goddard Space Flight Center in Greenbelt, Maryland. "This is an important continuation of the time series for Arctic ice, particularly with the very warm Arctic winter noticeably impacting sea ice retreat and ice sheet melt onset this year."

  • Do You Conserve Water? You Could Probably Stand to Do Much More

    Nearly 15 percent of the contiguous United States is suffering from moderate to severe drought, which makes water conservation critical in certain parts of the country. How do we convince people to save more water, though?

    That’s the question that professors at the University of Florida Institute of Food and Agricultural Sciences put to the test. They polled over 1,000 people in Florida to determine which types of people would respond best to conservation efforts, and the answer is a little counterintuitive: target people who are already saving some water.

  • NASA satellite sees heavy rain in tropical depression Bonnie

    The Global Precipitation Measurement mission known as GPM passed over Tropical Depression Bonnie and found heavy rainfall from a few thunderstorms within.

    Tropical Storm Bonnie weakened to a tropical depression on May 29, 2016. The circulation was labeled as "post-tropical" and has been moving very slowly to the northeast near the Carolinas coastline. Bonnie developed organized convection near the center and on June 2, 2016 the system was again labeled a tropical depression.

  • NASA studies details of a greening Arctic

    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?

    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

    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.

  • Spring comes sooner to urban heat islands, with potential consequences for wildlife

    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

    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.
