Taming the Butterfly

Americans' belief in global warming is on the rise, along with temperatures and surprising weather changes, according to a new university poll.

The invention of a long-lasting incandescent light bulb in the 19th century spurred on the second wave of the industrial revolution, illuminating homes, extending leisure time and bringing us to the point today where many millions of people use a whole range of devices from mood lighting to audiovisual media centers, microwave ovens to fast-freeze ice makers, and allergy-reducing vacuum cleaners to high-speed broadband connected computers in their homes without a second thought.

Researchers at Oak Ridge National Laboratory (ORNL) are sharing computational resources and expertise to improve the detail and performance of a scientific application code that is the product of one of the world's largest collaborations of climate researchers. The Community Earth System Model (CESM) is a mega-model that couples components of atmosphere, land, ocean, and ice to reflect their complex interactions. By continuing to improve science representations and numerical methods in simulations, and exploiting modern computer architectures, researchers expect to further improve the CESM's accuracy in predicting climate changes. Achieving that goal requires teamwork and coordination rarely seen outside a symphony orchestra.

Bird migration timing across North America has been affected by climate change, according to a study published Feb. 22 in the open access journal PLoS ONE.

The modernization of isolated villages brings about a change in human information flow patterns that not only destroys the social fabric of the community, but also the economy and the landscape, according to Sander van der Leeuw, a Senior Sustainability Scientist at Arizona State University's Global Institute of Sustainability.

A famous mathematical formula which shook the world of ecology 40 years ago has been revisited and refined by two University of Chicago researchers in the current issue of Nature.

The instant communications technology that nurtured grassroots revolutions in the Arab world could also help farmers cope with climate change, according to Iowa State University researchers.

Populations of the rusty blackbird, a once-abundant North American species, have declined drastically in recent years, and Auburn University researchers say climate change is to blame.

Airborne gases get sucked into stubborn smog particles from which they cannot escape, according to findings by UC Irvine and other researchers published today in the Proceedings of the National Academy of Sciences.

Researchers at the Stockholm Environment Institute (SEI) at the University of York have played a key role in a new study that shows that implementing 14 key air pollution control measures could slow the pace of global warming, save millions of lives and boost agricultural production.

Indonesia has the potential to realize major reductions in national greenhouse gas emissions from deforestation, and simultaneously earn significant new income for national and regional governments, if policies to Reduce Emissions from Deforestation and forest Degradation (REDD+) are developed with strong and specific economic incentives, said scientists in a new paper published in the leading scientific journal Proceedings of the National Academy of Sciences

New research has found that individuals and the private sector have an important role to play in the provision of public policies to help society adapt to the impacts of climate change.

Scientists have offered up a convincing explanation for the harsh winters recently experienced in the Northern Hemisphere; increasing temperatures and melting ice in the Arctic regions creating more snowfall in the autumn months at lower latitudes.

Preserving diverse plant life will be crucial to buffer the negative effects of climate change and desertification in in the world's drylands, according to a new landmark study.

Wandering albatrosses have altered their foraging due to changes in wind fields in the southern hemisphere during the last decades. Since winds have increased in intensity and moved to the south, the flight speed of albatrosses increased and they spend less time foraging. As a consequence, breeding success has improved and birds have gained 1 kilogram. These are the results of the study of an international research team published in the latest issue of the Science journal. However, these positive consequences of climate change may last short if future wind fields follow predictions of climate change scenarios, researchers warn.

No less than one third of a car's fuel consumption is spent in overcoming friction, and this friction loss has a direct impact on both fuel consumption and emissions. However, new technology can reduce friction by anything from 10% to 80% in various components of a car, according to a joint study by VTT Technical Research Centre of Finland and Argonne National Laboratory (ANL) in USA. It should thus be possible to reduce car's fuel consumption and emissions by 18% within the next 5 to 10 years and up to 61% within 15 to 25 years.

"You hear that it's good to recycle everything," Mr. Herscher said, "and then you hear it takes more energy to recycle paper than it does to cut it down. It's really hard to know what the right thing to do is. This is a way to express my own frustrations."

Those making land use decisions to reduce the harmful effects of climate change have focused almost exclusively on greenhouse gases - analyzing, for example, how much carbon dioxide is released when a forest is cleared to grow crops. A new study in Nature Climate Change aims to present a more complete picture - to incorporate other characteristics of ecosystems that also influence climate.

Unprecedented levels of greenhouse gases in the Earth's atmosphere are disrupting normal patterns of glaciation, according to a study co-authored by a University of Florida researcher and published online Jan. 8 in Nature Geoscience.

Climate change in the form of reduced snowfall in mountains is causing powerful and cascading shifts in mountainous plant and bird communities through the increased ability of elk to stay at high elevations over winter and consume plants, according to a groundbreaking study in Nature Climate Change.
