Steepest drop in global temperature on record

Watts Up With That?

Stunning new data indicates El Nino drove record highs in global temperatures suggesting rise may not be down to man-made emissions

  • Global average temperatures over land have plummeted by more than 1C
  • Comes amid mounting evidence run of record temperatures about to end
  • The fall, revealed by Nasa satellites, has been caused by the end of El Nino

Global average temperatures over land have plummeted by more than 1C since the middle of this year – their biggest and steepest fall on record. According to satellite data, the late 2016 temperatures are returning to the levels they were at after the 1998 El Nino.

The news comes amid mounting evidence that the recent run of world record high temperatures is about to end. The fall, revealed by Nasa satellite measurements of the lower atmosphere, has been caused by the end of El Nino – the warming of…

Greenland glaciers – melt due to sea current change, not air temperature

From a Woods Hole Oceanographic Institution News Release : Team finds subtropical waters flushing through Greenland fjord

Waters from warmer latitudes — or subtropical waters — are reaching Greenland’s glaciers, driving melting and likely triggering an acceleration of ice loss, reports a team of researchers led by Fiamma Straneo, a physical oceanographer from the Woods Hole Oceanographic Institution (WHOI).

“This is the first time we’ve seen waters this warm in any of the fjords in Greenland,” says Straneo. “The subtropical waters are flowing through the fjord very quickly, so they can transport heat and drive melting at the end of the glacier.”

UK Researchers: Tax Food to Reduce Climate Change

Watts Up With That?

A group of researchers in Oxford University, England have suggested that imposing a massive tax on carbon intensive foods – specifically protein rich foods like meat and dairy – could help combat climate change.

Pricing food according to its climate impacts could save half a million lives and one billion tonnes of greenhouse gas emissions

Taxing greenhouse gas emissions from food production could save more emissions than are currently generated by global aviation, and lead to half a million fewer deaths from chronic diseases, according to a new study published in Nature Climate Change.

The study, conducted by a team of researchers from the Oxford Martin Programme on the Future of Food at the…

Hate Didn’t Elect Donald Trump; People Did

Tori's Thought Bubble

photo_72491_landscape_650x433

Over the summer, my little sister had a soccer tournament at Bloomsburg University, located in central Pennsylvania. The drive there was about three hours and many of the towns we drove through shocked me. The conditions of these towns were terrible. Houses were falling apart. Bars and restaurants were boarded up. Scrap metal was thrown across front lawns. White, plastic lawn chairs were out on the drooping front porches. There were no malls. No outlets. Most of these small towns did not have a Walmart, only a dollar store and a few run down thrift stores. In almost every town, there was an abandoned factory.

My father, who was driving the car, turned to me and pointed out a Trump sign stuck in a front yard, surrounded by weeds and dead grass. “This is Trump country, Tori,” He said. “These people are desperate, trapped for life in these small towns…

Who needs the Paris climate agreement? CO2 emissions are declining on their own

Watts Up With That?

From the UNIVERSITY OF EAST ANGLIA

Low growth in global carbon emissions continues for third successive year

Global carbon emissions from burning fossil fuels did not grow in 2015 and are projected to rise only slightly in 2016, marking three years of almost no growth, according to researchers at the University of East Anglia (UEA) and the Global Carbon Project.

The projected rise of only 0.2% for 2016 marks a clear break from the rapid emissions growth of 2.3% per year in the decade to 2013, with just 0.7 per cent growth seen in 2014.

The new data is published in the journal Earth System Science Data. It shows emissions growth remained below 1 per cent despite GDP growth exceeding 3 per cent.
