"Six environmental organizations on Tuesday called on the Environmental Protection Agency (EPA) to take more aggressive action in response to reports that an agency office manipulated assessments of chemical safety."

"The immense and forbidding Southern Ocean is famous for howling gales and devilish swells that have tested mariners for centuries. But its true strength lies beneath the waves." "Wilder winds are altering currents. The sea is releasing carbon dioxide. Ice is melting from below."

"Scientists have been able to draw links between a warming planet and hurricanes, heat waves and droughts, attributing the likelihood that climate change played a role in individual isolated events. The same can’t be said for tornadoes yet."

"The changes happening at the top of the planet could unfold elsewhere in the years to come, scientists report." "Across the icy dome that crowns the Earth, rising temperatures are turning the tundra greener and more lush. Beavers are expanding their range. Garbage from passing ships is fouling the shores. Wildfires are scorching the once permanently frozen lands of Siberia."

"Scientists have discovered a series of worrying weaknesses in the ice shelf holding back one of Antarctica’s most dangerous glaciers, suggesting that this important buttress against sea level rise could shatter within the next three to five years."

"Nasty winter tornadoes — like the deadly ones last week that hit five states — are likely to be stronger and stay on the ground longer with a wider swath of destruction in a warming world, a new study shows."

"The EPA has all but stopped posting online data about new types of problems commercial chemicals may cause, frustrating public interest groups and businesses that use the information to make health and safety decisions."

"The calendar said December but the warm moist air screamed of springtime. Add an eastbound storm front guided by a La Nina weather pattern into that mismatch and it spawned tornadoes that killed dozens over five U.S. states."
