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.
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.
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.
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.
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.
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.
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 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.
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.
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.
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.
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.
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.
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.
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.
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.
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).
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.
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.
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.
