• Food prices in U.S., world set to rise as a result of drought

    The U.S. Midwest is suffering the worst drought since 1956, and a total of 1,369 counties in thirty-one states across the United States have been designated for disaster aid; the prolonged drought will lead to an increase in food prices in 2013 as animal feed costs increase

  • Global warming unequivocal in its advance, says NCAA expert

    Global warming is unequivocal in its advance and will lead to more record-setting temperatures, says Warren Washington, a senior scientist at the National Center for Atmospheric Research; in a talk at Sandia Lab, Washington presented graph after graph showing how various atmospheric processes have combined to create stronger rainfall near the equator and more intense droughts in the subtropics, as well as sea-level rises and increased storm surges

  • Predictions by climate models are flawed, says MIT meteorology expert

    Massachusetts Institute of Technology professor Richard Lindzen, a global warming skeptic, says that too much is being made of climate change by researchers seeking government funding; he said their data and their methods did not support their claims; for thirty years, climate scientists have been “locked into a simple-minded identification of climate with greenhouse-gas level. That climate should be the function of a single parameter (like CO2) has always seemed implausible. Yet an obsessive focus on such an obvious oversimplification has likely set back progress by decades,” Lindzen said

  • Large, magnitude 8 earthquakes hit New Zealand with regularity

    A new study finds that very large earthquakes have been occurring relatively regularly on the Alpine Fault along the southwest coastline of New Zealand for at least 8,000 years

  • Studying the physics of avalanches

    Snow avalanches, a real threat in countries from Switzerland to Afghanistan, are fundamentally a physics problem: What are the physical laws that govern how they start, grow, and move, and can theoretical modeling help predict them? New study offers answers

  • Capturing CO2 directly from air is chemically, economically viable

    With a series of papers published in chemistry and chemical engineering journals, researchers from the Georgia Institute of Technology have advanced the case for extracting carbon dioxide directly from the air using newly developed adsorbent materials

  • Pulling CO2 from air feasible, if still costly, way to curb global warming

    Emerging techniques to pull carbon dioxide from the air and store it away to stabilize the climate may become increasingly important as the planet tips into a state of potentially dangerous warming; lower-cost technology is a stumbling block so far

  • Temperature rise, CO2 follow each other closely

    The greatest climate change the world has seen in the last 100,000 years was the transition from the ice age to the warm interglacial period; new research indicates that, contrary to previous opinion, the rise in temperature and the rise in the atmospheric CO2 follow each other closely in terms of time

  • Replacing coal with natural gas would reduce global warming

    A new study finds that a gas substitution scenario, in which natural gas replaces all coal power production and any new oil-powered facilities by midcentury, would realize 40 percent of the reduction in global warming that could be achieved with a full switch to low-carbon fuel sources; this is a less costly, and more feasible, option, than switching all electricity generation immediately and aggressively to non-fossil fuel sources such as solar, wind, and nuclear

  • Per capita CO2 emissions in China reach EU levels

    Global emissions of carbon dioxide (CO2)  increased by 3 percent last year; an estimated cumulative global total of 420 billion tons of CO2 has been emitted between 2000 and 2011 due to human activities, including deforestation; scientists suggest that in order to limit the rise in average global temperature to 2°C above pre-industrial levels, cumulative CO2 emissions in the period 2000–50 cannot do not exceed 1,000 to 1,500 billion tons

  • Studies of nuclear weapons make a contribution to climate science

    Nuclear weapons testing may at first glance appear to have little connection with climate change research, but key cold war research laboratories and the science used to track radioactivity and model nuclear bomb blasts have today been repurposed by climate scientists

  • Will rising temperatures lead to rising crime rates?

    General Strain Theory has become one of the leading explanations for crime, and Emory University’s Professor Robert Agnew, has become its chief architect; he argues that rising temperatures will lead to more strains — increased temperatures, heat waves, natural disasters, serious threats to livelihood (farming, herding, fishing), forced migrations on a massive scale, and social conflicts arising as nations and groups compete for increasingly scarce food, fresh water, and fuel – and more strains invariably lead to rising crime rates

  • Emissions from oil sands-derived fuels too varied for uniform low-carbon standards

    Policy makers need to be cautious in setting new low-carbon standards for greenhouse gas emissions for oil sands-derived fuels as well as fuels from conventional crude oils; researchers found that lifecycle greenhouse gas (GHG) emissions vary widely across both actual surface mining and in situ oil sands operations and conventional crude cases reported in the scientific literature, depending on individual project operating conditions, technology used, and other factors

  • Environmental changes lead stressed cows in southern U.S. to produce less milk

    Researchers found that the decline in milk production due to climate change will vary across the United States, since there are significant differences in humidity and how much the temperature swings between night and day across the country; for instance, the humidity and hot nights make the Southeast the most unfriendly place in the country for dairy cows

  • Explaining 2011 extreme weather events

    2011 will be remembered as a year of extreme weather events, both in the United States and around the world; NOAA says that every weather event that happens now takes place in the context of a changing global environment; a comprehensive annual report – State of the Climate in 2011 — provides scientists and citizens with an analysis of what has happened so organizations and individuals can prepare for what is to come
