• Researchers Report New Understanding of Global Warming

    Researchers know that more, and more dangerous, storms have begun to occur as the climate warms. A team of scientists has reported an underlying explanation, using meteorological satellite data gathered over a 35-year period.

    The examination of the movement and interaction of mechanical energies across the atmosphere, published Jan. 24 in the journal Nature Communications, is the first to explore long-term variations of the Lorenz energy cycle – a complex formula used to describe the interaction between potential and kinetic energy in the atmosphere – and offers a new perspective on what is happening with global warming.

  • NOAA's GOES-16 satellite sends first images of Earth

    Since the GOES-16 satellite lifted off from Cape Canaveral on November 19, scientists, meteorologists and ordinary weather enthusiasts have anxiously waited for the first photos from NOAA’s newest weather satellite, GOES-16, formerly GOES-R.

    The release of the first images today is the latest step in a new age of weather satellites. It will be like high-definition from the heavens.

  • FSU scientist's findings on carbon cycle feed climate research

    A Florida State University researcher is taking a deep dive into the carbon cycle and investigating how carbon moves from the ocean surface to greater depths and then remains there for hundreds of years.

  • Mapping out a low-carbon future

    Fulfilling the promise of the 2015 Paris Agreement on climate change — most notably the goal of limiting the rise in mean global surface temperature since preindustrial times to 2 degrees Celsius — will require a dramatic transition away from fossil fuels and toward low-carbon energy sources. To map out that transition, decision-makers routinely turn to energy scenarios, which use computational models to project changes to the energy mix that will be needed to meet climate and environmental targets. These models account for not only technological, economic, demographic, political, and institutional developments, but also the scope, timing, and stringency of policies to reduce greenhouse gas emissions and air pollution.

  • How Climate Change Impacts Our Water Supply

    The water cycle, the process by which water circulates through the planet’s atmosphere and waterways, helps make life here on Earth possible.

    Climate change, however, caused by excessive greenhouse gas emissions, is disrupting that process. It’s creating a vicious cycle in which higher temperatures, changes in rainfall and water contamination cause environmental consequences that make global warming worse and damage the health of the planet further.

  • How Much Drought Can a Forest Take?

    Aerial tree mortality surveys show patterns of tree death during extreme drought.

    Why do some trees die in a drought and others don’t? And how can we predict where trees are most likely to die in future droughts?

  • Climate change prompts Alaska fish to change breeding behavior

    One of Alaska’s most abundant freshwater fish species is altering its breeding patterns in response to climate change. This could impact the ecology of northern lakes, which already acutely feel the effects of a changing climate.

    That’s the main finding of a recent University of Washington study published in Global Change Biology that analyzed reproductive patterns of three-spine stickleback fish over half a century in Alaska’s Bristol Bay region. The data show that stickleback breed earlier and more often each season in response to earlier spring ice breakup and longer ice-free summers.

  • Research shows driving factors behind changes between local and global carbon cycles

    Pioneering new research has provided a fascinating new insight in the quest to determine whether temperature or water availability is the most influential factor in determining the success of global, land-based carbon sinks.

    The research, carried out by an international team of climate scientists including Professors Pierre Friedlingstein and Stephen Sitch from the University of Exeter, has revealed new clues on how land carbon sinks are regulated on both local and global scales.

  • Green Sahara's Ancient Rainfall Regime Revealed by Scientists

    Rainfall patterns in the Sahara during the 6,000-year "Green Sahara" period have been pinpointed by analyzing marine sediments, according to new research led by a UA geoscientist.

    What is now the Sahara Desert was the home to hunter-gatherers who made their living off the animals and plants that lived in the region's savannahs and wooded grasslands 5,000 to 11,000 years ago.

  • Changing atmospheric conditions may contribute to stronger ocean wave activity on the Antarctic Peninsula

    Over the past few years, a large fracture has grown across a large floating ice shelf on the Antarctic Peninsula. The world is watching the ice shelf, now poised to break off an iceberg the size of Delaware into the ocean.

    It’s not a new phenomenon; this “thumb” of Antarctica, which juts out into the stormy Southern Ocean, has lost more than 28,000 square kilometers of floating ice — almost as large as Massachusetts — over the past half-century. This has included the complete disintegration of four ice shelves, the floating extensions of glaciers.
