Ocean heating breaks record, again, with disastrous outcomes for the planet

By Elizabeth Claire Alberts via Mongabay New research shows that ocean temperatures are hotter than ever in the modern era due to human-driven global warming. High ocean temperatures are placing a strain on marine life and biological processes while also increasing extreme weather events on land. The world is also seeing an escalation in the frequency and intensity of marine heat waves, events in which sea temperatures exceed a certain […]

From trash to power: how to harness energy from Africa’s garbage dumps – and save billions in future damage

By Nkweauseh Reginald Longfor, Sophia University New research on garbage dumps in 44 sub-Saharan African countries shows that 95% are unregulated. The landfill sites still take in new garbage even when they are filled to capacity. As the waste decomposes, these sites release harmful greenhouse gases. However, using the methane gas to generate energy instead could save the continent billions of dollars. We talk to sustainability scientist and author of […]
