Climate scientists to issue dire warnings

A new study published yesterday suggests that the short-term warming due to increasing greenhouse gases may be less than previously feared. However, when we look at the bigger picture, we still find that cli ...

(Phys.org) —What happened the last time a vegetated Earth shifted from an extremely cold climate to desert-like conditions? And what does it tell us about climate change today?

Australia said it was pushing for a ban Thursday of any commercial use of a pioneering technique to reduce the impacts of climate change by "fertilising" the world's oceans with iron, warning of significant ...

Removing excess carbon dioxide (CO2) from the atmosphere may be essential to curb severe climate change. Possible, but expensive, methods include burying the gas underground between rock layers or 'scrubbing' ...

Ocean acidification is damaging some marine species while others thrive, say scientists. An international team studied the effect of ocean acidification on plankton in the North Sea over the past forty years, ...

Concerns continue to grow about the effects of climate change on fire. Wildfires are expected to increase 50 percent across the United States under a changing climate, over 100 percent in areas of the West by 2050 as projected ...

(Phys.org) —Computer simulations of galaxies growing over billions of years have revealed a likely scenario for how they feed: a cosmic version of swirly straws.

It's 1.7 miles long. Its surface is covered in a sticky black substance similar to the gunk at the bottom of a barbecue. If it impacted Earth it would probably result in global extinction. Good thing it is ...

The majority of people on Earth people will face severe water shortages within a generation or two if pollution and waste continues unabated, scientists warned at a conference in Bonn Friday.

Astronomers from the University of Antioquia have discovered a graveyard of comets. These once-dormant comets, dubbed by astronomers as "The Lazarus comets," are now rejuvenated.

(Phys.org) —A trio of German space scientists has worked out a way to use pulsars as navigation aids for space vehicles traveling in the solar system. As they describe in their paper uploaded to the preprint ...
