Study Slashes Deforestation Carbon Emission Estimate

A new study with NASA participation has sharply reduced previous estimates of how much carbon was emitted into Earth's atmosphere from tropical deforestation in the early 2000s.

Significant Sea Level Rise in a 2-Degree Warming World

The study is the first to give a comprehensive projection for this long perspective, based on observed sea-level rise over the past millennium, as well as on scenarios for future greenhouse-gas emissions.

Arctic Climate More Vulnerable Than Previously Thought

First analyses of the longest sediment core ever collected on land in the Arctic, published this week in Science, provide dramatic, "astonishing" documentation that intense warm intervals, warmer than scientists thought possible, occurred there over the past 2.8 million years.

U.S. Fish and Wildlife Service Launches Interactive Website on Endangered Species

The U.S. Fish and Wildlife Service Endangered Species Program has launched a new, web-based interactive map with information about endangered species success in every state.

Melting Sea Ice Threatens Emperor Penguins

If global temperatures continue to rise, the Emperor penguins in Terre Adélie, in East Antarctica, may eventually disappear, according to a new study by led by researchers from the Woods Hole Oceanographic Institution (WHOI).

Expansion of Forests in the European Arctic Could Result in the Release of Carbon Dioxide

Carbon stored in Arctic tundra could be released into the atmosphere by new trees growing in the warmer region, exacerbating climate change, scientists have revealed.

As World Warms, Conservation Evolves

Climate and Conservation offers a glimpse of climate change beyond images of melting Arctic ice—illustrating that landscapes and seascapes in places like the coastal Caribbean, mountainous eastern Australia, and the Brazilian Amazon are all susceptible to climate related impacts.

Grasshoppers Frightened By Spiders Affect Whole Ecosystem

How do grasshoppers who are being frightened by spiders affect our ecosystem? In no small measure, say researchers at the Hebrew University of Jerusalem and at Yale University in the US.



Texas A&M Experts Make New Underwater Discoveries

Texas A&M University, one of a few select schools that carries the rare designation of being a land grant, sea grant and space grant institution, has several researchers who have identified new marine species.

Global Climate Change: Underestimated Impact of Sea Level Rise on Habitat Loss?

The hidden impact of sea-level rise: current projections may be underestimating the consequences of global climate change on habitat loss.

Climate Change Will Alter Risks of Wildfire Worldwide, Some Shifts Rapid, Extensive

A Texas Tech University climate scientist said climate change is widely expected to disrupt future fire patterns around the world, with some regions, such as the western United States, seeing more frequent fires within the next 30 years.

Great Lakes Initiative Cleanup Helps Restore Grand Calumet River

The recent completion of a $52 million project to rid Roxana Marsh of contaminated sediment will speed the recovery of Indiana’s Grand Calumet River, marking a step forward for one of the Great Lakes’ most complex Area of Concern cleanups.

Humans are Primary Cause of Global Ocean Warming Over Past 50 Years, Research Shows

The oceans have warmed in the past 50 years, but not by natural events alone. New research shows that the observed ocean warming over the last 50 years is consistent with climate models only if the models include the impacts of observed increases in greenhouse gas during the 20th century.

Microbial Communities Changed After Deepwater Horizon Spill

Communities of microbial organisms -- species such as nematodes, protists and fungi -- on beaches along the Gulf of Mexico changed significantly following the Deepwater Horizon oil spill in April 2010, research from the University of New Hampshire’s Hubbard Center for Genome Studies (HCGS) and partners found.

Environmental Monitoring of Algal Blooms in a River System

CAS DataLoggers recently provided the data-logging solution for an environmental organization monitoring an outbreak of algal blooms in a major river.

Ecologists Call for Preservation of Planet's Remaining Biological Diversity

Twenty years after the Earth Summit in Rio de Janeiro, 17 prominent ecologists are calling for renewed international efforts to curb the loss of biological diversity, which is compromising nature's ability to provide goods and services essential for human well-being.

Consumption Driving Environment Damage: UN

A group of scientists from around the world is warning that population growth, widespread destruction of natural ecosystems, and climate change may be driving Earth toward an irreversible change in the biosphere, a planet-wide tipping point that would have destructive consequences absent adequate preparation and mitigation.

Plastic Particles More Prevalent Than Previously Thought

For decades, oceanographers have collected water samples from the surface of the ocean in order to record how much plastic debris currently litters the waters. But a new study asserts that surface collection alone is insufficient because high winds have a tremendous impact on the buoyancy of the plastic debris.

Algae and Mosses Take Up Huge Amounts of Carbon Dioxide and Nitrogen

In cities, the presence of algae, lichens, and mosses is not considered desirable and they are often removed from roofs and walls. It is, however, totally unfair to consider these cryptogamic covers, as the flat growths are referred to in scientific terms, just a nuisance.

Why Wildfire is Important to the Ecosystem

Researchers studying Lake Tahoe have found that not only could a major disturbance like a fire affect Lake Tahoe, but so too could a lack of disturbance -- the absence of a fire.
