Temperature<br />
increases<br />
from climate change are<br />
generally estimated at<br />
1.4-5.8°C by 2100 if<br />
further action is not taken.<br />
The EU intends to limit its<br />
greenhouse gases on par<br />
with a global rise of 2°C<br />
in 2020, but some studies<br />
indicate this still might not<br />
avoid catastrophe.<br />
Atmospheric<br />
Greenhouse<br />
Gases (GHG),<br />
most notably CO 2<br />
,<br />
methane, and NO 2<br />
,<br />
are the most threatening<br />
and avoidable agents of<br />
climate change. In 2008,<br />
CO 2<br />
levels hit 336 ppm,<br />
the highest in at least<br />
650,000 - and possibly<br />
20 million - years.<br />
Ocean Life<br />
and Acidity<br />
will result from the<br />
increased CO 2<br />
emissions,<br />
threatening all hubs of<br />
marine biodiversity.<br />
Ocean warming is adverse<br />
to growth of sea algae,<br />
the source of half of<br />
all photosynthesised<br />
oxygen and the basis<br />
of the marine food chain.<br />
Biodiversity<br />
Loss<br />
has already been seen.<br />
Climate change increases<br />
the risk of extinction for<br />
about 20-30% of all<br />
species and puts immense<br />
stress on ecological<br />
systems, particularly<br />
threatening those in<br />
tropical forest, alpine,<br />
and Arctic regions.<br />
Understanding Climate Change and<br />
Responding to Ecological Challenges<br />
Greater Climate<br />
Extremes<br />
through drought,<br />
floods, and extreme<br />
weather will affect global<br />
circulations of air and<br />
water. The result will<br />
be crippling to farmland,<br />
habitable land and<br />
water infrastructure,<br />
while increasing the<br />
spread of deadly<br />
diseases.<br />

Future<br />
Generations<br />
are at stake. The needs<br />
of the present generation<br />
must not compromise the<br />
needs of future ones.<br />
Agricultural, economic,<br />
energy, and social<br />
practices that maximise<br />
energy efficiency, and<br />
organic replacement rates<br />
are therefore a priority.<br />
Managing<br />
the Cost<br />
of this climate change is<br />
crucial. It is estimated that<br />
the cost of keeping global<br />
warming below 2°C and<br />
reducing GHG emissions<br />
by 70% by 2020, could<br />
be as little as €530 billion,<br />
or 1% of the global GDP.<br />
Action shall be taken<br />
swiftly.<br />
The UN<br />
Copenhagen<br />
Conference<br />
has failed to decide on<br />
a post-2012 framework<br />
for climate change.<br />
Alas, the 25%-40%<br />
reduction in GHGs from<br />
1990 levels by 2020 as<br />
urged by the scientific<br />
community is still far<br />
from being met.<br />
