Delay in Autumn Colour is Caused by Increased Atmospheric CO2 not Global Warming
November 19, 2007 08:44 AM - University of Southampton
The delay in autumnal leaf coloration and leaf fall in trees is caused by rising levels of carbon dioxide (CO2) in the atmosphere and not by increased global temperatures, suggests a new study by researchers at the University of Southampton.
In recent years, woodland autumnal colour changes have been occurring later in the season whilst re-greening in spring has been occurring earlier. During the last 30 years across Europe, autumnal senescence – the process of plant aging where leaves discolour and then fall – has been delayed by 1.3 - 1.8 days a decade. To date, this has been explained by global warming, with increasing temperatures causing longer growing seasons.
Act Now on Climate Change: Go For Energy Efficiency.
November 19, 2007 08:06 AM - , Private Landowner Network
The latest report on the state of global warming from the Intergovernmental Panel on Climate Change ((IPCC) warns that without action soon climate change may cause abrupt and irreversible impacts.
(Glaciers, like those on Greenland, may experience rapid meltdown and cause sea levels to rise. Once gone glaciers won’t freeze up again. Droughts similar to that now being experienced in the southeast US may be more frequent and perhaps permanent. Populations without water to support them will have to move, never to return.)
