Severe droughts are on the rise in many regions worldwide and are increasingly affecting a wide range of
ecosystems — including marshes, mangroves,
temperate and tropical forests, grasslands and coral
reefs — that provide essential services to humans and the environment alike, Silliman said.
The Global Biodiversity Outlook 4 (CBD 2014), while finding some improvements in
temperate and developed parts of the world and the ongoing enlargement of the protected - area estate, also presented evidence of climate - induced effects on biodiversity; the increased spread of diseases and invasive biota; declines in species living in forests,
reefs, and many other habitats; and the conversion of
ecosystems supporting many kinds of life to ones with singular human uses.
