"Timing matters: Flowers bloom, insects emerge, birds migrate, and planting and hunting seasons are carefully coordinated times in order to take advantage of what other organisms, or the weather, is up to. But increasing research is showing some of these relationships are falling out of sync as climate change alters important cues, such as the arrival of spring warmth."
"Evidence going back decades and sometimes even longer shows the timing of some biological events is shifting around the world. Studies document the progressively earlier arrival of spring, by about 2.3 to 5.2 days per decade in the last 30 years, according to the Intergovernmental Panel on Climate Change's 2007 report. That report lists studies showing changes in seasonal timing, or phenology, of the first and last leaves on gingko trees in Japan, butterfly emergence in the United Kingdom, bird migrations in Australia, the first leaves and flowers of lilacs in North America, among many others.
But not everything is changing together, leading to complex results."
The NESTown development concept envisions the building of self-sufficient, environmentally friendly 'semi-urban centers' in rural Ethiopia that would allow farmers to improve their financial prospects without abandoning the land.
By 2050, the world's population will have increased by 3 billion people, requiring an additional chunk of arable land the size of Brazil in order to grow (@mlkingh here is the link: http://t.co/a165GNlH...)...
