• Hawaii's Fishermen: Scapegoats for Forces Outside their Control

    Climate change is affecting fisheries in the Western Pacific and around the world, but a host of other factors, including land use, are threatening fisheries and the health and integrity of marine ecosystems. Aiming for sustainable fisheries, marine policymakers, resource managers, fishermen and other stakeholders are increasingly looking to take a more holistic, integrated approach to fisheries management, as evidenced during the latest meeting of the Western Regional Fishery Management Council (WRFMC) meeting, which was held in Oahu. Often blamed for overexploiting fish stocks, local fishermen in Hawaii are keenly aware of external impacts on the health and integrity of marine ecosystems and fish populations. At the latest WRFMC meeting in Honolulu, they argued in support of taking a more comprehensive ecosystems management approach, specifically zooming in on how land use and associated runoff from cities, agriculture and industry are harming marine ecosystems and fisheries. >> Read the Full Article
  • Is EV battery technology more advanced than we thought?

    Are EV manufacturers holding something back? If we take a look at the EV market it seems that we have barely moved on, at least in the mass market, since the General Motors EV1 debacle in the 1990s. Mainstream battery journey capacity is still roughly the same as was available for the EV1 despite the fact that the industry has received billions of dollars in additional funding from governments and private investors. So, are EV manufacturers holding something back? There is some speculation that various EV manufacturers are holding back the best of their technology until it has been fine tuned and thoroughly tested. There is speculation that while some of the "financially weak" companies are falling by the wayside, in the shape of Fisker for example, we are starting to see some stronger companies emerge from the market. This is potentially the perfect storm for the EV market, with companies falling by the wayside leaving the lion's share of future investment to those looking further forward and able to give stability and long-term credibility. >> Read the Full Article
  • The Jet Stream and Greenland

    There are many dynamics in the world. There are many global phenomena. Add the the jet stream to climate change. Research from the University of Sheffield has shown that unusual changes in atmospheric jet stream circulation caused the exceptional surface melt of the Greenland Ice Sheet (GrIS) in the summer 2012. An international team led by Professor Edward Hanna from the University of Sheffield’s Department of Geography used a computer model simulation (called SnowModel) and satellite data to confirm a record surface melting of the GrIS for at least the last 50 years - when on 11 July 2012, more than 90 percent of the ice-sheet surface melted. This far exceeded the previous surface melt extent record of 52 percent in 2010. >> Read the Full Article
  • Arabian Sea at High Risk of Quakes and Tsunamis

    Countries surrounding the Arabian Sea may be at a much higher risk of a major earthquake and tsunami than previously thought, say researchers. A tsunami in this area of the Western Indian Ocean could threaten the coastlines of India, Iran, Oman, Pakistan and further afield. The scientists say further investigation should feed into hazard assessments and planning for such events in the region. >> Read the Full Article
  • Update: UN climate change talks start making progress

    The United Nations climate change body said it has made concrete progress towards a new universal agreement on climate change during its latest round of talks which wrapped up this week in Germany. "This has been an important meeting because Governments are moving faster now from the stage of exploring options to designing and implementing solutions," said Christiana Figueres, Executive Secretary of the UN Framework Convention on Climate Change (UNFCCC). During the two-week talks in Bonn, participants focused on how to transform the world's energy systems quickly enough towards low-carbon, including renewable energy, energy efficiency and the consideration of carbon capture and storage. >> Read the Full Article
  • Logging may destabilize carbon in forest soils

    Logging in temperate zones may release more greenhouse gases than previously thought by destabilizing carbon stored in forest soils, argues a new paper published in the journal Global Change Biology-Bioenergy. The research involved analysis of carbon released from forest management practices in the northeastern United States. It found that while most models assume carbon stored in mineral soils to be relatively stable, in fact intensive logging operations, like clear-cutting, trigger release of carbon from various pools above and below ground. >> Read the Full Article
  • New poll confirms majority of public support renewable energy

    A new survey report has revealed that the majority of the public believe the Government should support the construction of more renewable energy sources like solar, wave and tidal power. And the poll, commissioned by the Institute of Mechanical Engineers, found a third of those questioned would even consider investing in small-scale community renewable projects like wind farms, solar farms or small-scale biomass plants. >> Read the Full Article
  • How can agriculture best adapt to changing climate?

    Whether it’s swapping coffee for cocoa in Central America or bracing for drought in Sri Lanka with a return to ancient water storage systems, findings from a new report from the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) chart a path for farmers to adapt to climate shifts despite uncertainties about what growing conditions will look like decades from now. As this week's UN climate talks in Bonn continue to sideline a formal deal on agriculture, the study, Addressing uncertainty in adaptation planning for agriculture, which was published recently in the Proceedings of the National Academies of Sciences (PNAS), finds that the cloudy aspects of climate forecasts are no excuse for a paralysis in agriculture adaptation policies. "Climate projections will always have a degree of uncertainty, but we need to stop using uncertainty as a rationale for inaction," said Sonja Vermeulen, head of research at CCAFS and the lead author of the study. "Even when our knowledge is incomplete, we often have robust grounds for choosing best-bet adaptation actions and pathways, by building pragmatically on current capacities in agriculture and environmental management, and using projections to add detail and to test promising options against a range of scenarios." >> Read the Full Article
  • Better Land Use May Help Protect Coral Reefs

    According to new research, for nations that have outlying coral reefs, better land use of the mainland is crucial in order to prevent further damage to these ocean habitats. A recent study reveals important implications for Madagascan and Australian reefs based on deforestation scenarios. >> Read the Full Article
  • Odd Martian Thermal Rhythm

    Researchers using NASA's Mars Reconnaissance Orbiter have found that temperatures in the Martian atmosphere regularly rise and fall not just once each day, but twice. "We see a temperature maximum in the middle of the day, but we also see a temperature maximum a little after midnight," said Armin Kleinboehl of NASA's Jet Propulsion Laboratory in Pasadena, Calif., who is the lead author of a new report on these findings. Temperatures swing by as much as 58 degrees Fahrenheit (32 kelvins) in this odd, twice-a-day pattern, as detected by the orbiter's Mars Climate Sounder instrument. >> Read the Full Article
