• Another Study Points to Climate Change's Direct Role in Fueling Extreme Weather

    Climate change is impacting major air currents that control extreme weather events, helping to power natural disasters like heat waves, droughts, wildfires, and floods in North America, Europe, and Asia, according to a new study published in the journal Scientific Reports.

  • Spiral of doom: hotter world increases cattle methane emissions

    A vicious cycle of climate change, cattle diet and rising methane has been revealed in a new scientific study: as temperatures rise, forage plants get tougher and harder to digest, and cause more methane to be produced in bovine stomachs. And with cattle numbers rising and methane 85 times more powerful a greenhouse gas over 20 years, that spells trouble.

  • Extreme weather events linked to climate change impact on the jet stream

    Unprecedented summer warmth and flooding, forest fires, drought and torrential rain — extreme weather events are occurring more and more often, but now an international team of climate scientists has found a connection between many extreme weather events and the impact climate change is having on the jet stream.

  • Rising Flood Insurance Costs a Growing Burden to Communities and Homeowners in New York City

    Flood insurance is already difficult to afford for many homeowners in New York City, and the situation will only worsen as flood maps are revised to reflect current risk and if the federal government continues to move toward risk-based rates, according to a first-of-its-kind study by the RAND Corporation.

  • Northern oceans pumped CO2 into the atmosphere

    At the same time the pH of the surface waters in these oceans decreased, making them more acidic. Both of these findings imply changes in ocean circulation and primary productivity as a result of natural climate changes of the time. The findings were recently published in Nature Communications.

    Oceans changed function

    Today the cold Arctic and Nordic Seas are especially efficient areas for uptake of CO2 from the atmosphere. The oceans have been capable of mitigating some of the increase in greenhouse gas release resulting from human activities such as combustion of fossil fuels, by absorbing about 40% of the emitted CO2

    “Our research shows that areas in Norwegian Sea had changed their function on  several occasions through the past 135 000 years: Instead of absorbing CO2 from the air, they released more of the greenhouse gas into it.” says first author of the study Mohamed Ezat from Centre of Arctic Gas Hydrate, Environment and Climate (CAGE), Department of Geosciences at UiT The Arctic University of Norway.

  • NASA Examines Peru's Deadly Rainfall

    The Global Precipitation Measurement mission or GPM constellation of satellites provide data on precipitation rates and totals. Recently the GPM core observatory measured the heavy rainfall that caused extensive flooding and loss of life in Peru.

    Extreme flooding and frequent landslides that occurred in March have forced many from their homes. An El Niño-like condition with warm ocean waters developed near Peru's coast. This extremely warm water off Peru's western coast has been blamed for promoting the development of these storms. Equatorial sea surface temperatures (SSTs) are about average elsewhere in the central and east central Pacific.

  • UTA biologist quantifying coral species' disease susceptibility by examining immune traits

    A biologist from The University of Texas at Arlington is leading a new study aimed at quantifying how susceptible coral species are to disease by examining their immunity through a series of novel experiments and approaches.

    Laura Mydlarz, associate professor of biology, is principal investigator of the project, titled “Immunity to Community: Can Quantifying Immune Traits Inform Reef Community Structure?” and funded by a two-year, $220,331 grant from the National Science Foundation’s Division of Ocean Sciences. Co-principal investigators are Marilyn Brandt, research associate professor of marine and environmental science at the University of the Virgin Islands, and Erinn Muller, staff scientist at the Mote Marine Laboratory and Aquarium in Sarasota, Fla.

  • NASA Sees System 91P Coming Together East of Queensland

    The area of tropical low pressure designated System 91P appears to be organizing in NASA satellite imagery on March 24. Visible imagery from NASA-NOAA's Suomi NPP satellite revealed that the tropical low is consolidating and strengthening in the Coral Sea, South Pacific Ocean.

    On March 24, 2017, the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard the NASA-NOAA Suomi NPP satellite captured a visible image of developing System 91P. The image showed bands of thunderstorms spiraling into the low-level center of circulation.

  • Winter Sets Up Bird Breeding Success

    For migratory birds, breeding grounds are where the action is. But a new study by University of Guelph biologists is among the first to suggest that the number of songbirds breeding during spring and summer depends mostly on what happens at their wintering grounds.
