Changes in Rainfall Patterns are Projected for Next 30 Years

Manoa have projected an increased frequency of heavy rainfall events but a decrease in rainfall intensity during the next 30 years (2011-2040) for the southern shoreline of Oahu, according to a recent study published in the Journal of Geophysical Research.

Liquid Catalyst Converts Emissions into Fuel

An Illinois research team has succeeded in overcoming one major obstacle to a promising technology that simultaneously reduces atmospheric carbon dioxide and produces fuel.

New Study Shows How Trees Clean the Air

New research shows how trees can improve air quality by filtering out pollution particulates, which are damaging to human health.

China's CO2 Emission Increases Substantially

Constructing buildings, power plants and roads has driven a substantial increase in China's CO2 emission growth.

Rethinking the Connection Between Soil as a Carbon Reservoir and Global Climate Change

Research suggests soil environment determines humus depletion, which means the question as to how soils respond to global climate change needs to be readdressed.

Physicists Examine Their Own Carbon Footprint

In October's issue of Physics World, Phil Marshall, an astrophysicist at the University of Oxford, calls on physicists to pull their weight when it comes to climate change, drawing on his own research showing that astronomers average 23,000 air miles per year flying to observatories, conferences and meetings, and use 130 KWh more energy per day than the average U.S. citizen.

Nuclear Power Has Prevented 40M Metric Tons of CO2 Emissions

More than 10 years after electricity deregulation, the nuclear power industry has decreased greenhouse gas emissions by nearly 40 million metric tons of carbon dioxide and saved $2.5 billion a year as a result of operating more efficiently over the past decade, according to a new study.

High Air, Water Quality Are Key to a More-Pleasant Beach Vacation

People head to the beach to escape the stress of everyday life, but a new study out of the Brown School at Washington University in St. Louis finds that there are peak times to reap the restorative benefit.



Research Suggests Global Warming Could Cause Animals to Shrink

The way in which global warming causes many of the world’s organisms to shrink has been revealed by new research from Queen Mary, University of London.

Climate Change Has Affected Marine Animals on Antarctica's Seabed

A rapid increase in the frequency of icebergs pounding the shallow seafloor around the West Antarctic Peninsula — as a result of shrinking winter sea ice — has caused the life expectancy of a tiny marine creature to halve over the last 12 years.

Bionic Bacteria May Help Fight Disease and Global Warming

A strain of genetically enhanced bacteria developed by researchers at the Salk Institute for Biological Studies may pave the way for new synthetic drugs and new ways of manufacturing medicines and biofuels, according to a paper published September 18 in Nature Chemical Biology.

Satellites Measurements of Megacity Emissions Far Exceed Computer Estimates

One of NASA's satellites has provided the most detailed map yet of the pollution generated by some of the world’s biggest cities, and given an indication of the volume of emissions of the nitrogen oxides from direct measurements rather than relying on computer models and a range of assumptions.

Scientists Probe Indian Ocean for Clues to Worldwide Weather Patterns

An international team of researchers will begin gathering in the Indian Ocean next month to study how tropical weather brews there and then moves eastward along the equator with reverberating effects around the entire globe. They will use a vast array of tools ranging from aircraft and ships to moorings, radars, and numerical models.

Model Successfully Forecasts Arctic Sea Ice Season

Relatively accurate predictions for the extent of Arctic sea ice in a given summer can be made by assessing conditions the previous autumn, but conditions more than five years into the future depend on understanding the impact of climate trends on the ice pack, new research shows.

Despite Reductions by Industrialized Countries, Global CO2 Emissions Increase Steeply

Global emissions of carbon dioxide (CO2) increased by 45 percent between 1990 and 2010, and reached an all-time high of 33 billion tons in 2010. Increased energy-efficiency, nuclear energy and the growing contributions of renewable energy are not compensating for the globally increasing demand for power and transport, which is strongest in developing countries.

Deforestation May Be Reducing Rainfall in Africa

Deforestation in the rainforests of West Africa reduces rainfall over the rest of the forest, according to new University of Leeds research published in Geophysical Research Letters. The study shows that changing land use from forest to crop land reduces rainfall over neighboring trees by about 50 percent due to changes in the surface temperature, which affects the formation of rain clouds.

Paper Points Out Weaknesses in Climate-Change Data Observation

Our most reliable models rely on data acquired through a range of complex measurements. Most of the important measurements - such as ice cover, cloud cover, sea levels and temperature, chlorophyll (oceans and land) and the radiation balance (incoming to outgoing energy) – must be taken from space, and for constraining and testing the forecast models, made over long timescales.

Oceans May Mask Effects of Global Warming

The planet’s deep oceans at times may absorb enough heat to flatten the rate of global warming for periods of as long as a decade even in the middle of longer-term warming, according to a new analysis led by the National Center for Atmospheric Research (NCAR).

Study: Carbon Sequestration Presents No Threat to Human Health

Capturing CO2 from power stations and storing it deep underground carries no significant threat to human health, despite recently voiced fears that it might, a study has shown.

Planting Trees on Farms Can Greatly Improve Food Security

Restoring and preserving dryland forests and planting more trees to provide food, fodder and fertilizer on small farms are critical steps toward preventing the recurrence of the famine now threatening millions of people in the Horn of Africa, according to forestry experts from the CGIAR Consortium.
