A new NOAA-sponsored report shows that air temperature in 2015 across the Arctic was well above average with temperature anomalies over land more than 2 degrees Fahrenheit above average, the highest since records began in 1900.
Scientists with the USDA Forest Service have developed a new approach to forest carbon accounting that will result in a more accurate picture of how much carbon is sequestered in forests - the planet's greatest terrestrial carbon sink - and the ramifications of changes in land use, wildfire and invasive insects on carbon sequestration.
Computer simulations have allowed scientists to work out how a puzzling 555-million-year-old organism with no known modern relatives fed, revealing that some of the first large, complex organisms on Earth formed ecosystems that were much more complex than previously thought.
Global warming will progress faster than what was previously believed. The reason is that greenhouse gas emissions that arise naturally are also affected by increased temperatures. This has been confirmed in a new study from Linköping University that measures natural methane emissions.
The rate of carbon burial in remote lakes has doubled over the last 100 years, suggesting even isolated ecosystems are feeling the effects of our changing climate.
A new study from the University of Exeter, published in the journal Ecology Letters, found that phytoplankton - microscopic water-borne plants - can rapidly evolve tolerance to elevated water temperatures. Globally, phytoplankton absorb as much carbon dioxide as tropical rainforests and so understanding the way they respond to a warming climate is crucial.
A comprehensive scientific report released today by The Royal Society of Canada (RSC) has concluded that there are still critical research gaps hampering efforts to both assess the environmental impacts of crude oil spills and to effectively remediate them.
In the pristine wilds of the Antarctic, the mysterious leopard seal rules the animal kingdom. This polar bear-sized top predator has razor-sharp canine teeth and the ability to greatly impact or even decimate entire communities of its prey, yet very few scientific studies have focused on this species.
The warming of arctic waters in the wake of climate change is likely to produce radical changes in the marine habitats of the High North. This is indicated by data from long-term observations in the Fram Strait, which researchers from the Alfred Wegener Institute (AWI) have now analysed. Their most important finding: even a short-term influx of warm water into the Arctic Ocean would suffice to fundamentally impact the local symbiotic communities, from the water's surface down to the deep seas. As the authors recently reported in the journal "Ecological Indicators", that's precisely what happened between 2005 and 2008.
NASA begins a five-year study this month of the annual cycle of phytoplankton and the impact that small airborne particles emitted from the ocean have on the climate-sensitive North Atlantic.
