Global Warming News -- ScienceDaily
  • Antarctic ice shelves rapidly thinning
    A new study has revealed that the thickness of Antarctica's floating ice shelves has recently decreased by as much as 18 percent in certain areas over nearly two decades, providing new insights on how the Antarctic ice sheet is responding to climate change.

  • Deadly Japan earthquake and tsunami spurred global warming, ozone loss
    Buildings destroyed by the 2011 Tohoku earthquake released thousands of tons of climate-warming and ozone-depleting chemicals into the atmosphere, according to a new study.

  • Increased sensitivity to climate change in disturbed ecosystems
    Undisturbed ecosystems can be resistant to changing climatic conditions, but this resistance is reduced when ecosystems are subject to natural or anthropogenic disturbances. Plants are particularly sensitive to climatic changes in early life stages and even small climatic changes can cause vegetation shifts when ecosystems are disturbed by fires, insect outbreaks or other disturbances.

  • Climate refuges found where corals survive, grow
    As rising ocean temperatures continue to fuel the disappearance of reef-building corals, a new study finds there may be some climate refuges where corals will survive in the future.

  • More big storms increase tropical rainfall totals
    Increasing rainfall in certain parts of the tropics, colloquially described as the wet get wetter and warm get wetter, has long been a projection of climate change. Now observations have shown that an increase in large thunderstorms is the primary reason for this phenomenon.

  • Shell-shocked: Ocean acidification likely hampers tiny shell builders in Southern Ocean
    A ubiquitous type of phytoplankton -- tiny organisms that are the base of the marine food web -- appears to be suffering from the effects of ocean acidification caused by climate change. According to authors of a new study, the single-celled organism under study is a type of "calcifying" plankton called a coccolithophore, which makes energy from sunlight and builds microscopic calcium carbonate shells, or plates, to produce a chalky suit of armor.

  • Management of peatlands has large climate impacts
    Drainage and management of pristine peatlands increase greenhouse gas emissions into the atmosphere. A recent study, based on a new, wide data set collected from northern peatlands indicates that particularly those peatlands which have been taken into agricultural use have significant warming impact on climate.

  • Greenhouse gases unbalanced: How human intervention changes wetlands
    Natural wetlands usually emit methane and sequester carbon dioxide. Anthropogenic interventions, in particular the conversion of wetlands for agriculture, result in a significant increase in carbon dioxide emissions, which overcompensate potential decreases in methane emission. A large international research team now calculated that the conversion of arctic and boreal wetlands into agricultural land would result in an additional cumulative radiative forcing of about 0.1 mJ per square meter for the next 100 years.

  • No baked beans: Surprising discovery of elite heat-tolerant beans could save 'meat of the poor' from global warming
    Amidst fears that global warming could zap a vital source of protein that has sustained humans for centuries, bean breeders have announced the discovery of 30 new types, or lines as plant breeders refer to them, of ?heat-beater? beans that could keep production from crashing in large swaths of bean-dependent Latin America and Africa.

  • Doubling of coastal erosion by mid-century in Hawai'i
    Chronic erosion dominates the sandy beaches of Hawai'i, causing beach loss as it damages homes, infrastructure, and critical habitat. Researchers have long understood that global sea level rise will affect the rate of coastal erosion. However, new research indicates that coastal erosion of Hawai'i's beaches may double by mid-century.

  • Looking to space to quantify natural gas leaks on Earth
    Increasing natural gas production could provide a bridge to a lower carbon future. However, methane that is leaked into the atmosphere from this process could speed global warming and climate change. And there is controversy over just how much methane is lost. Researchers have developed new methods to determine methane's leakage rate and problems inherent in discovering and assessing leakage.

  • Mimicking nature's chemistry to solve global environmental problems
    Catalysis could be made to help harness greenhouse gases, experts say.

  • Ascension of marine diatoms linked to vast increase in continental weathering
    A team of researcher has used mathematical modeling to show that continental erosion over the last 40 million years has contributed to the success of diatoms, a group of tiny marine algae that plays a key role in the global carbon cycle.

  • Ocean circulation changing: Ten years of ocean monitoring uncovers secrets of changing UK winters
    A groundbreaking project to observe and analyse regular data about ocean circulation and how it impacts Britain's climate has reached a 10-year milestone, giving valuable new insights into how ocean currents can affect global warming.

  • Gulf Stream system: Atlantic Ocean overturning, responsible for mild climate in northwestern Europe, is slowing
    The Atlantic overturning is one of Earth's most important heat transport systems, pumping warm water northwards and cold water southwards. Also known as the Gulf Stream system, it is responsible for the mild climate in northwestern Europe. Scientists now found evidence for a slowdown of the overturning -- multiple lines of observation suggest that in recent decades, the current system has been weaker than ever before in the last century, or even in the last millennium.
