Climate-Linked Drought Cutting Forests’ Carbon-Storing Ability – Climate extremes are dramatically cutting the ability of trees to sequester carbon, threatening to convert some forests from carbon sinks into carbon sources, finds a study published this month in Environmental Research Letters, reports Mongabay.com.

Tropical Fish Migrating To and Deforesting Temperate Oceans reportsJoanna Foster at Climate Progress. As grazing tropical fish migrate into the warming temperate zones, they are eating up temperate kelp forests, especially on the southern coast of Japan, where 40% of the kelp and algal beds have disappeared in the past 20 years.

The results are as dramatic as when terrestrial forests are clearcut. Similar undersea deforestation is occurring in the Mediterranean and off the west coast of Australia.

Meanwhile, warming temperate waters are similarly allowing warmer water species to migrate into the northeast Atlantic, with equally dramatic results: the ratio of warmer water species are increasing, but overall biodiversity is dropping.

Natural Disasters Have Increased 500% Since 1970s says a new atlas of death and loss compiled by the United Nations, reports Suzanne Goldenberg at the UK Guardian. Disasters such as storms, floods and heatwaves have increased, which is predicted under continued global warming.

Although improved warning systems are preventing loss of life, the social-economic impacts are increasing, due to the increased frequency and intensity of disasters, and increased vulnerability of human societies.

Join the swelling numbers of voters TELLING Congress they’ll vote for Clean Energy candidates here. This is an ongoing campaign (the next Congressional election is this year!) so please, spread the word. It’s our way of telling Congress that a strong clean energy voting bloc is out there. This is how YOU can make a difference.
