About $700 billion a year of new spending on renewable power, low-carbon transport and energy efficiency is needed to meet the United Nations goal to cap temperature rises, a report for the World Economic Forum showed.

That cash is needed in addition to the $5 trillion a year countries must spend on infrastructure for agriculture, transport, power and water through 2020, according to a report released today by the consultant Accenture Plc (ACN) for the forum’s Green Growth Action Alliance. ...

Scrapping the worst pollution-emitting stoves could prevent 22.5 million early deaths by 2100

The first large-scale study of cooking stoves that burn solid fuel such as coal or wood has estimated that phasing out the stoves could prevent about 260,000 premature deaths from indoor pollution globally each year.

More than 3 billion people '€“ that's in excess of 40% of the world's population '€“ use cooking stoves that burn solid fuel such as coal, wood or dried animal dung. These fuels result in the release of fine particulate matter, which exacerbates respiratory conditions such as asthma and has been linked to lung cancer. ...

HISTORIC HEAT Sea levels were 6 to 9 meters higher than present-day levels the last time Earth’s climate was this warm, new research suggests. Similar sea level rise today would submerge many coastal areas (red). JOHN C. KOSTELNICK (DATA), GSFC/NASA (VISUALIZATION)

The last time Earth's thermostat was cranked as high as it is today, sea levels were high enough to completely drown New Orleans (had it existed at the time), new research suggests. ... Read more about Here's what happened to sea levels the last time Earth was this warm

Today marks the third day of COP21, a key milestone in the global effort to combat climate change. For the next two weeks, representatives from more than 190 countries will work towards creating a legally binding and universal agreement that spells out how countries will cooperate on climate change for decades to come. A strong Paris agreement can send the signal to the world that the global transformation to a climate-resilient, zero-carbon economy is underway. ...

The apocalypse has a new date: 2048.

That's when the world's oceans will be empty of fish, predicts an international team of ecologists and economists. The cause: the disappearance of species due to overfishing, pollution, habitat loss, and climate change.

The study by Boris Worm, PhD, of Dalhousie University in Halifax, Nova Scotia, -- with colleagues in the U.K., U.S., Sweden, and Panama -- was an effort to understand what this loss of ocean species might mean to the world. ... Read more about Salt-Water Fish Extinction Seen By 2048

Ocean acidification may cause dramatic changes to phytoplankton

Author: 

Jennifer Chu | MIT News Office
Show

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. ...
