New maps show how shipping noise spans the globe
Scientists have modeled shipping noise on a global scale.
Global warming caused by CFCs, not carbon dioxide, researcher claims in controversial study
Chlorofluorocarbons are to blame for global warming since the 1970s and not carbon dioxide, a researcher claims in a controversial new study. CFCs are already known to deplete ozone, but in-depth statistical analysis now suggests that CFCs are also the key driver in global climate change, rather than carbon dioxide emissions, the researcher argues.
Rainforests take the heat, paleontologists show
Rainforests thrived during previous global warming events, say paleontologists.
Land-based carbon offsets: False hope? Forest and soil carbon is important, but does not offset fossil fuel emissions
Leading world climate change experts have thrown cold water on the idea that planting trees can offset carbon dioxide emissions from fossil fuels. Land carbon sinks cannot solve the problem of atmospheric carbon emissions but they legitimize the ongoing use of fossil fuels.
Arctic current flowed under deep freeze of last ice age, study says
During the last ice age, when thick ice covered the Arctic, many scientists assumed that the deep currents below that feed the North Atlantic Ocean and help drive global ocean currents slowed or even stopped. But in a researchers have now shown that the deep Arctic Ocean has been churning briskly for the last 35,000 years, through the chill of the last ice age and warmth of modern times.
Despite safety and other concerns, nuclear power saves lives, greenhouse gas emissions, experts say
Global use of nuclear power has prevented about 1.84 million air pollution-related deaths and release of 64 billion tons of greenhouse gases that would have resulted from burning coal and other fossil fuels, a new study concludes.
Geochemistry survey at Chatham Rise reveals absence of modern day greenhouse gas emissions
Geochemistry analysis of fossil sediment injection structures off the New Zealand coast in February and March reveal no presence of modern day expulsions of methane gas, a potential contributor to global 'greenhouse effect' warming.
Ancient plants reawaken: Plants exposed by retreating glaciers regrowing after centuries entombed under ice
When Catherine La Farge threads her way through the recently exposed terrain left behind by retreating glaciers, she looks at the ancient plant remains a lot closer than most. Now, her careful scrutiny has revealed a startling reawakening of long-dormant plants known as bryophytes.
Historic sea-level change along New Jersey coastline mapped
A new study relied upon fossil records of marshland to reconstruct the changes in sea level along the New Jersey coast going back 10,000 years.
Fast-sinking jellyfish could boost the oceans' uptake of carbon dioxide
Increasing numbers of gelatinous plankton might help in mitigating the carbon dioxide problem. In field and laboratory experiments scientists have shown that dead jellyfish and pelagic tunicates sink much faster than phytoplankton and marine snow remains.
