Ecosystems Face Unprecedented Climate Change Velocity
2013-08-02 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: Over the next century, plants and animals on land might be in for a wild and ultimately devastating ride. Warming temperatures, changing precipitation patterns, and extreme weather and climate events are likely to increase at a rate and magnitude not seen in more than 65 million years, according to a new study published Thursday in the journal Science. Couple that with other human-related ecosystem disruptions, from highways to deforestation to pollution, and some species could find themselves pushed...

Tropical ecosystems regulate variations in Earths carbon dioxide levels

CSIRO: The study, published in the journal Proceedings of the National Academy of Sciences, found that a temperature anomaly of just 1C (in near surface air temperatures in the tropics) leads to a 3.5-Petagram (billion tonnes of carbon) anomaly in the annual CO2 growth rate, on average. This is the equivalent of 1/3 of the annual global emissions from the combustion of fossil fuels and deforestation together. Importantly, the NASA Earth Exchange (NEX) study results provide scientists with a new diagnostic...

Tropical Ecosystems Boost Carbon Dioxide as Temperatures Increase

Nature World News: Unlike in other parts of the word, tropical ecosystems are capable of generating significant carbon dioxide when temperatures rise, an international team of researchers has found. Specifically, the scientists discovered that a temperature increase of just 1 degree Celsius in near-surface air temperatures in the tropics results in an average annual growth rate of atmospheric carbon dioxide that is equivalent to one-third of the annual global emissions caused by the combustion of fossil fuels and...

Coral Reef Ecosystems Devastated by Climate Change

EcoWatch: Marine biologists worst fears seem to be confirmed: coral colonies take a long time to recover from catastrophic climate events. British and Brazilian biologists report in the Public Library of Science One (PLoS One) that the richest habitats of the sea could also be among the most vulnerable to climate change. Bleached coral at a site in Palau monitored by the Palau International Coral Reef Center, juxtaposed with healthy, living coral. The number and extent of bleaching events have been...

Stressed Ecosystems Leaving Humanity High and Dry

Inter Press Service: Everyone knows water is life. Far too few understand the role of trees, plants and other living things in ensuring we have clean, fresh water. This dangerous ignorance results in destruction of wetlands that once cleaned water and prevented destructive and costly flooding, scientists and activists warn."We have accelerated major processes like erosion, applied massive quantities of nitrogen that leaks from soil to ground and surface waters and, sometimes, literally siphoned all water from rivers."...
