July 17 - Jellyfish spark marine life feast in Wales
Rare leatherback turtles, basking sharks and superpods of dolphins have all been spotted in Welsh seas in the past few weeks. While it's encouraging, much of the abundance is due to warmer waters and the presence of the jellyfish in huge numbers which are prey to other species. Around the world jellyfish numbers are increasing and scientists have linked these increases to factors such as pollution, over-fishing and possibly climate change. Read more

July 16 - Report: "future warming could be more intense"
New research published in Nature Geoscience shows that during a period about 55 million years ago when the planet warmed rapidly, only about 40% of that warming can be attributed to rises in carbon dioxide in the atmosphere. A co-author of the research said that given this, future warming could be more intense than people anticipate. Read more.

July 14 - India's deadly water wars
Across much of northern India, a late monsoon and the driest June for 83 years are worsening the effects of a widespread drought and setting neighbour against neighbour in a desperate fight for survival.

July 1 - Desert dust increases mountain thaw
Desert dust is darkening the surface of winter snows on the San Juan mountains, warming it by absorbing sunlight that the white surface would have reflected. Snow is now melting earlier than in the past, running off before the air has warmed enough to spur plant growth. Dust levels in the mountains are around five times greater than they were prior to the mid-19th century. Read more
