Fewer than 7% of global hotspots for whale-ship collisions have protection measures in place, researchers report
According to the fossil record, cetaceans—whales, dolphins and their relatives—evolved from four-legged land mammals that returned to the oceans beginning some 50 million years ago. Today, their descendants are threatened by a different land-base.....»»
Staggering temperature rise predicted for the Middle East and North Africa
The Middle East and North Africa, which already include some of the hottest and driest spots on Earth, are undergoing accelerated climate change and will reach warming thresholds two to three decades earlier than the rest of the world, a new study re.....»»
Support for carbon pricing higher than expected, finds study
Viewed by many experts as one of the most effective tools of climate policy, carbon pricing seeks to reduce carbon dioxide emissions. Currently, however, only 23% of global greenhouse gas emissions are subject to this climate tax, as it is seen as un.....»»
Madagascar"s huge ocean algae bloom was caused by dust from drought-stricken southern Africa
Scientists have found new evidence that desertification, potentially linked to global warming, leads to large amounts of nutrient-rich dust landing in the sea, causing ocean algae to grow rapidly. Biological oceanographer John A. Gittings and an inte.....»»
