Recent studies have focused on the short-term contribution of the Greenland ice sheet to sea-level rise, yet little is known about its long-term stability. The present best estimate of the threshold in global temperature rise leading to complete melting of the ice sheet is 3.1 °C (1.9–5.1 °C, 95% confidence interval) above the preindustrial climate, determined as the temperature for which the modeled surface mass balance of the present-day ice sheet turns negative. Here, using a fully coupled model, we show that this criterion systematically overestimates the temperature threshold and that the Greenland ice sheet is more sensitive to long-term climate change than previously thought.

The contribution of climate change to declining populations of organisms remains a question of outstanding concern. Much attention to declining populations has focused on how changing climate drives phenological mismatches between animals and their food. Effects of climate on plant communities may provide an alternative, but particularly powerful, influence on animal populations because plants provide their habitats. Here, we show that abundances of deciduous trees and associated songbirds have declined with decreasing snowfall over 22 years of study in Montane, Arizona, USA.

Catastrophic decline in freshwater mussels may impact water quality and other species. These invertebrates play a crucial role in river ecosystems. With support from the National Science Foundation (NSF), Caryn Vaugh studies mussels' role in their environment. Almost 70 percent of the species are considered threatened in some way. They're the most globally threatened freshwater organism there is.

Sustained conservation of species requires integration of future climate change effects, but few tools exist to assist managers. The System for Assessing Vulnerability of Species (SAVS) identifies the relative vulnerability or resilience of vertebrate species to climate change.

If global warming continues as expected, it is estimated that almost a third of all flora and fauna species worldwide could become extinct. Scientists from the Biodiversity and Climate Research Centre (Biodiversität und Klima Forschungszentrum, BiK-F) and the SENCKENBERG Gesellschaft für Naturkunde discovered that the proportion of actual biodiversity loss should quite clearly be revised upwards: by 2080, more than 80 % of genetic diversity within species may disappear in certain groups of organisms, according to researchers in the title story of the journal Nature Climate Change. The study is the first world-wide to quantify the loss of biological diversity on the basis of genetic diversity.

Today, the U.S. Environmental Protection Agency is launching a new tool to allow 28 industrial sectors to submit their 2010 greenhouse gas (GHG) pollution data electronically. Prior to being finalized, more than1,000 stakeholders, including industry associations, states and NGOs tested the electronic GHG Reporting Tool (e-GGRT) to ensure clarity and user-friendliness.

Climate Change Hurts Indian Tribes Disproportionately, Report Finds

North American Indian Tribes are especially harmed by climate change, as more ecological shifts and more frequent, more extreme weather events occur, a new study concludes. Because Tribes are heavily dependent on natural resources, severe weather events like droughts, floods, wildfires, and snowstorms make tribal communities particularly vulnerable and impact American Indians and Alaska Natives more than they impact the general population.
