Islamic Climate Declaration
Islamic environmental and religious leaders have drafted a declaration on climate change. The Declaration calls for “all people, leaders and businesses, to commit to 100% renewable energy" and focusses on "well-off nations and oil-producing states," to lead the way in phasing out greenhouse gases, no later than the middle of this century. We discuss the significance of this latest involvement of a world religion in the climate change debate.

West Antarctic Ice Sheet
New research published in the journal The Cryosphere this week suggests that the west Antarctic Ice Sheet could contribute up to 6cm to global sea level rise by the end of the century. The work adds to the growing body of evidence that the west Antarctic ice sheet will play a role in rising sea levels.

Deep Sea Coral
