Declining cost of renewables and climate change curb the need for African hydropower expansion
Hydropower, traditionally one of Africa's most important sources of electricity, will rapidly fade in importance and cede its position to solar power. The attractiveness of new hydropower is decreasing fast, both due to the increasing economic compet.....»»
Coral reefs: How climate change threatens the hidden diversity of marine ecosystems
Like the heat waves on land we have all grown familiar with, marine heat waves are being amplified by climate change. These extreme warm water events have ushered in some of the most catastrophic impacts of climate change and are now a major threat t.....»»
Leakage or spillover? Conservation parks boost biodiversity outside them, but there"s a catch, new study shows
It's easy to assume protected areas such as national parks conserve wildlife—that seems obvious. But what is the proof? And how does park success vary across different ecosystems—in deserts versus tropical rainforests, or wetlands versus oceans?.....»»
Marine heat wave impact on corals worse than previously thought, according to new research
The effects of marine heat waves caused by climate change on corals and biodiversity are worse than previously thought, according to new University of Victoria research. Published in Science Advances the research also provides important clues about b.....»»
Plankton are central to life on Earth: How is climate change affecting them?
Recently, scientists reported that more than half of our oceans are turning greener, an indication that they might contain more phytoplankton. Along the California coast, hundreds of sea lions and dolphins turned up sick or dying after being exposed.....»»

A newly discovered immune strategy protects bacteria and more advanced species, from corals to bees
Every time we make a call, send a text message or watch a video, some of the energy stored in the cell phone battery is depleted. Living cells also store energy in "currencies" they can cash in when needed, in order to fuel life processes. The main e.....»»
California aims to introduce more anglers to native warm-water tolerant sunfish as planet heats up
California's only native sunfish, the Sacramento perch, survived catastrophic floods in the 1860s and was so abundant that it was a regular staple in San Francisco's markets before invasive species decimated its population......»»
"Planting" rocks in farms, along with emissions reductions, could help meet key IPCC carbon removal goal
Farmers around the world could help the planet reach a key carbon removal goal set by the Intergovernmental Panel on Climate Change (IPCC) by mixing crushed volcanic rocks into their fields, a new study reports. The study also highlights wet, warm tr.....»»
Atlantic collapse: Q&A with scientists behind controversial study predicting a colder Europe
