    WEF's annual state-of-play survey asks the views of a range of decision-makers and experts as to what they see as being the biggest risks facing the world today. It appears that while the types of risks have changed little in the last few years, the perceived level of risk and resulting impact has grown. Of the 1,000 respondents, 59 percent pointed to an intensification of risk; just 7 percent suggested a declining of risk.

    Rising temperatures and changing precipitation are taking a toll on coffee farms worldwide, including the plantations around Mount Kilimanjaro. If the world hopes to sustain its two billion cup-a-day habit, scientists say, new climate-resilient species of coffee must be developed.

    New data released by the U.S. Energy Information Administration also highlighted another potential contradiction: Virtually every state suing to block the Clean Power Plan has itself shifted toward burning less coal to generate the electricity its residents need since the year 2007 - in some cases by very large amounts.

    A huge swath of the Antarctic ice cap is already crumbling, and preventing the thawing of the ice caps might now be impossible, a major new study suggests. The melting of the area studied alone would raise the world's sea level by nearly four feet, and total thawing could lead to up to a 12-foot surge in sea levels. Still, that probably won't happen for a century or two, since the ice is melting slowly, researchers say

    A new study has unveiled humanity's sweeping impact on the world's oceans. Commercial fishing, climate change, agricultural runoff and other human-caused stressors have wiped out nearly 90 percent of Earth's marine wilderness, researchers from the University of California at Santa Barbara and the University of Queensland, Australia revealed.
