Global Climate Change


Humanmade Pollutants May Be Driving Earth's Tropical Belt Expansion

Black carbon aerosols and tropospheric ozone, both humanmade pollutants emitted predominantly in the Northern Hemisphere's low- to mid-latitudes, are most likely pushing the boundary of the tropics further poleward in that hemisphere, new research by a team of scientists shows.

USGS Details Effects of Climate Change on Water Availability in 14 Local Basins Nationwide

Climate change projections indicate a steady increase in temperature progressing through the 21st century, generally resulting in snowpack reductions, changes to the timing of snowmelt, altered streamflows and reductions in soil moisture, which could affect water management, agriculture, recreation, hazard mitigation and ecosystems across the nation.

Nearly One Tenth of Western Hemisphere Mammals Unlikely to Outrun Climate Change

A safe haven could be out of reach for 9 percent of the Western Hemisphere's mammals, and as much as 40 percent in certain regions, because the animals just won't move swiftly enough to outpace climate change.

New Research Brings Satellite Measurements and Global Climate Models Closer

One popular climate record that shows a slower atmospheric warming trend than other studies contains a data calibration problem, and when the problem is corrected the results fall in line with other records and climate models, according to a new University of Washington study.

Warming Affects Ecosystems Not Just Biodiversity

Ecosystems perform important tasks – like nutrient cycling, breakdown of waste and carbon storage – on which humans depend, so it's important we understand how climate change might affect them.

Study Shows Antarctic Waters Changing due to Climate

The densest waters of Antarctica have reduced dramatically over recent decades, in part due to man-made impacts on the climate, Australian scientists said Friday.

Global Change Puts Plankton Under Threat

Changes in the ocean’s chemistry, as a result of increasing atmospheric carbon dioxide (CO2) levels, threaten marine plankton to a greater extent than previously thought, according to new research.

Scientists Core Into Clear Lake in California to Explore Past Climate Change

Scientists at University of California, Berkeley, will begin drilling into ancient sediments at the bottom of Northern California's Clear Lake to look at how today's plants and animals will adapt to climate change and increasing population.



Study Shows Experiments Underestimate Plant Responses to Climate Change

Researchers from UC San Diego have analyzed 50 plant studies on four continents to see how plants will respond to climate change in the future. Their study, published this week in the journal Nature, found that shifts in the timing of flowering and leafing in plants due to global warming appear to be much greater than estimated by warming experiments.

Mining for Heat

A group of researchers from McGill University in Canada has taken a systematic look at how such heat might be put to use once mines are closed. They calculate that each kilometer of a typical deep underground mine could produce 150 kW of heat, enough to warm five to 10 Canadian households during off-peak times.

Stream Temperatures Don't Parallel Warming Climate Trend

A new analysis of streams in the western United States with long-term monitoring programs has found that despite a general increase in air temperatures over the past several decades, streams are not necessarily warming at the same rate.

Oil Palm Surging Source of Greenhouse Gas Emissions

Continued expansion of industrial-scale oil palm plantations on the island of Borneo will become a leading cause of greenhouse gas emissions by 2020 unless strong forest and peatland protections are enacted and enforced, according to a National Academy of Sciences study.

Climate Change May Create Price Volatility in the Corn Market

By the time today's elementary schoolers graduate from college, the U.S. corn belt could be forced to move to the Canadian border to escape devastating heat waves brought on by rising global temperatures. If farmers don't move their corn north, the more frequent heat waves could lead to bigger swings in corn prices -- "price volatility" -- which cause spikes in food prices, farmers' incomes and the price livestock farmers and ethanol producers pay for corn.

Mild Winters Are Detrimental to Butterflies

The recent mild winter throughout much of the United States was a cause for celebration for many. However, butterfly aficionados shouldn't be joining in the celebration.

New Poll Finds Americans Want Less Population Growth 40 years After Government Called for Stabilization

Forty years after a multi-year bi-partisan government commission recommended slowing U.S. population growth and eventually stabilizing, Americans still would like to see it happen, according to poll results to be released this weekend at the 2012 Earth Day Dallas festival.

Can Sound Science Guide Dispersant Use During Subsea Oil Spills?

Two years ago this week, oil began streaming from the seafloor into the Gulf of Mexico following the explosion of the Deepwater Horizon platform. All told, the disaster cost 11 lives, released 4.9 million barrels of crude oil, and caused still unspecified impacts to marine life and the Gulf economy.

Study Suggests Drastic Changes Needed to Curb Most Potent Greenhouse Gas

Meat consumption in the developed world needs to be cut by 50 percent per person by 2050 if we are to meet the most aggressive strategy, set out by the Intergovernmental Panel on Climate Change (IPCC), to reduce one of the most important greenhouse gases, nitrous oxide (N2O).

Rapid Climate Change Threatens Asia's Rice Bowl

As Asia's monsoon season begins, leading climate specialists and agricultural scientists warned today that rapid climate change and its potential to intensify droughts and floods could threaten Asia's rice production and pose a significant threat to millions of people across the region.

New Forage Plant Prepares Farmers for Climate Changes

Researchers, including plant researchers from the University of Copenhagen, have developed a new type of the corn-like crop sorghum, which may become very significant for food supplies in drought-prone areas.

Ecologist Simulates Climate Change with Infrared Heaters

Climate change is leading to higher temperatures around the world, forcing plants, trees and animals to adapt to new conditions or relocate, often to higher elevations. But the process is gradual, and the effects of climate warming can usually only be observed over the course of years and decades.
