Aussie town battles tumbleweed invasion: A climate change signal?

Christian Science Monitor: Hairy panic, a perennial weed native to inland Australia, has taken over the rural city of Wangaratta in northern Victoria. Walked out the front door this morning to find a good six-metre [19-foot] spread of tumbleweed across the front of the house again, Wangaratta local Jason Pera tells Australia Broadcasting Corporation (ABC) Thursday. It makes it difficult to get the car out in the morning if you can find it. Images and videos of panicum effusum, adequately nicknamed hairy panic,...

Climate: Vegetation Sensitivity to Climate Variability Mapped Worldwide
2016-02-18 21:04:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: Parts of the world's boreal forests, Arctic tundra, tropical rainforest, and alpine areas, along with the rest of our earthly kit-and-caboodle, have now been incorporated into a global map of areas that are most sensitive to climate variability, say researchers with a study recently published in the journal Nature. "Based on the satellite data gathered, we can identify areas that, over the past 14 years, have shown high sensitivity to climate variability," researcher Alistair Seddon at Norway's...

Mapping the world for climate sensitivity
2016-02-18 21:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: By using satellites, biologists are now able to map which areas are most sensitive to climate variability on a global scale. A new metric, Vegetation Sensitivity Index (VSI), allows a more quantifiable response to climate change challenges and how sensitive different ecosystems are to short-term climate anomalies. Ecologically sensitive regions are the Arctic tundra, parts of the boreal forest belt, the tropical rainforests, alpine regions worldwide, steppe and prairie regions of central Asia and...

Mapping Ecosystems Sensitivity to Climate Change

Yale Environment 360: Forests, tundras, and alpine areas are some of the worlds most at-risk ecosystems to climate change, according to a new map published in the journal Nature. The study, led by scientists at the University of Bergen in Norway, used satellite data collected from 2000 to 2013 to examine how sensitive plants were to changes in air temperature, water availability, and cloud cover, down to a two-square-mile scale. The scientists used the results to create the Vegetation Sensitivity Indexa visual guide...

The Heat Is On: Climate Change Causes Birds To Hatch Early
2016-02-18 20:26:00| Climate Ark Climate Change & Global Warming Newsfeed
Forbes: A recently published study reveals that climate change can cause birds eggs to hatch early. In addition to creating warmer temperatures that trigger early embryonic development in birds, climate change also increases the frequency and duration of heat waves. Thus, warming temperatures are leading to asynchronous hatching of individual eggs within a clutch and increased chick mortality, particularly for birds breeding in the tropics and semi-tropics, and in tropical deserts. Global warming is...
