Nigeria's vice-president on Thursday launched a $1 billion oil pollution clean-up program in the Niger delta, after President Muhammadu Buhari pulled out of visiting the restive region.

There are days when even a born optimist starts to waver in his conviction. The release of a new study projecting that sea level could rise between five and six feet by 2100—when many children born today will still be alive and have been forced to move inland—made Thursday one of those days.

Climate change now poses the single biggest threat to the world’s most famous heritage sites – including the Galápagos islands, the Statue of Liberty, Easter Island and Venice – according to a UN sponsored report.

The researchers looked at 31 natural and cultural world heritage sites in 29 countries that are vulnerable to increasing temperatures, melting glaciers, rising seas, more intense weather, worsening droughts and longer wildfire seasons. They believe this number is the tip of the iceberg.

A public backlash intensified Monday after zookeepers killed a critically endangered gorilla holding a young boy who had fallen into its enclosure in a horrifying incident captured on video.

The US would still meet its obligations under the Paris accord on climate change if Donald Trump were elected president, a senior US administration official has told the Guardian.

Harvest should be the time for celebrations, weddings and full bellies in southern Malawi. But Christopher Witimani, Lilian Matafle and their seven children and four grandchildren had nothing to celebrate last week as they picked their meagre maize crop.

The U.S. Court of Appeals for the D.C. Circuit surprised both sides in the closely watched Clean Power Plan case Monday by deciding to have a full panel of the active circuit judges hear the case — and to postpone the hearing until Sept. 27.

Although the circuit court move delays an initial hearing for four months, in the end a decision by the entire panel of active judges could speed up the appellate process, exclude some of the most conservative judges who are on senior status, and guard against the possibility of gridlock at the Supreme Court, where a tie 4-4 vote would leave the appellate court’s decision intact.
