Ocean acidification may cause dramatic changes to phytoplankton

Author:

Oceans have absorbed up to 30 percent of human-made carbon dioxide around the world, storing dissolved carbon for hundreds of years. As the uptake of carbon dioxide has increased in the last century, so has the acidity of oceans worldwide. Since pre-industrial times, the pH of the oceans has dropped from an average of 8.2 to 8.1 today. Projections of climate change estimate that by the year 2100, this number will drop further, to around 7.8 — significantly lower than any levels seen in open ocean marine communities today. ...

Scientists stunned by Antarctic rainfall and a melt area bigger than Texas

Scientists have documented a recent, massive melt event on the surface of highly vulnerable West Antarctica that, they fear, could be a harbinger of future events as the planet continues to warm.

In the Antarctic summer of 2016, the surface of the Ross Ice Shelf, the largest floating ice platform on Earth, developed a sheet of meltwater that lasted for as long as 15 days in some places. The total area affected by melt was 300,000 square miles, or larger than the state of Texas, the scientists report. ...

Achim Steiner: shale gas rush 'a liability' in efforts slow climate change

Shale gas could turn out to be "a liability" to global efforts limit climate change, the United Nations' top environmental official has warned.

Supporters of the shale gas boom, which has spread across America and more recently to Europe, claim the fuel could help wean economies off the more carbon-intensive coal,.

But Achim Steiner, who heads the United Nations Environmental Programme (UNEP), said there was a far greater risk that the switch from coal to natural gas would only delay the much more critical energy transition from fossil to renewable fuels. ...

It was almost 20 years ago that Ma Jun sat and watched the rainbow-coloured River Fen, in Shanxi province. As he turned to the skies in this coal and industrial heartland of north China he could see dozens of chimneys bellowing out their fumes.

Humans have caused an explosion of never-before-seen minerals all over the Earth

Author: 

Chelsea Harvey
Show

The human handprint on the natural world has become evident in all too many ways in recent decades. The changing climate, the decline of wildlife and the loss of forests and other natural landscapes — all of these factors have led many scientists to conclude that we’re living in a new age they’ve dubbed the “Anthropocene,” in which the planet is dominated by human, rather than natural, influences. ...

2016 Climate Trends Continue to Break Records

Author: 

www.nasa.gov - Patrick Lynch
Each of the first six months of 2016 set a record as the warmest respective month globally in the modern temperature record, which dates to 1880. Meanwhile, five of the first six months set records for the smallest monthly Arctic sea ice extent since consistent satellite records began in 1979.
Show

Two key climate change indicators -- global surface temperatures and Arctic sea ice extent -- have broken numerous records through the first half of 2016, according to NASA analyses of ground-based observations and satellite data. ... Read more about 2016 Climate Trends Continue to Break Records
