Overlay of the values within the last quartile (higher values) from each climate risk metric for scenario SSP3-7.0. Areas in the map are color-coded based on their overlap with hotspots of exposure identified based on different climate metrics (Local, local velocity; Analog, analog velocity; Magnitude). Areas with no analogues within the 1500 km search radius (NA values on land) are shown as blank spots (i.e. central Greenland). Map lines delineate study areas and do not necessarily depict accepted national boundaries.

Ten dead in ‘brutal’ attacks by Isis-linked militants on Mozambique wildlife reserve | Global development
One of Africa’s largest protected areas has been shaken by a series of attacks by Islamic State-linked extremists, which have left at least 10 people dead. Conservationists in Niassa reserve, Mozambique, say decades of work to rebuild populations of lions, elephants and other keystone species are being jeopardised, as conservation operations grind to a halt. On 29 April, militants attacked buildings in Niassa…

The difference between the number of men and women listed as authors on scientific papers and inventors on patents is at least partly attributable to unacknowledged contributions by women scientists.

This tigress has reclaimed the ancient fort within Bandhavgarh Tiger Reserve and made it her home. Protection, prey, peace, and prosperity have been key factors in the tiger recovery within India, according to a new Science study. Learn more in this week's issue: scim.ag/42yn5Ra
Cultural reverence toward tigers (Panthera tigris) has fostered tolerance and permitted coexistence with humans in India. Ecological restoration, socioeconomic policies, and political stability have facilitated the recovery of tigers within their historical range, despite high human densities. This tigress has reclaimed the ancient fort within Bandhavgarh Tiger Reserve and made it her home.
