(These Notes Basically have concept notes)
Recent developments in Global Warming:
Bali conference for 1 month from the 18th of
November to the 18th of December
Australia signs the Kyoto Protocol as soon as the New Australian PM was elected.
Carbon Credits as a concept. Carbon footprint, ecological
footprint as a concept.
Indian Nobel Peace Prize joint winner. Dr. Rajendra Pachauri
and Al Gore – Both won on Environmental Issues.
Amazon forest has taken its toll on the Amazon – the amount
of deforestation, equals the size of Jamaica. From 2000 to this date, the forest cover has increased by 20%.
In Indonesia, individuals at the grass root level – if you
want to get married, you have to plant 5 trees,
In the emergency in 1975, Sanjay Gandhi placed emphasis on
tree plantation along with sterilization.
Ecology deals with the interdependence of humans, animals
and flora fauna.
In Greenland, the ice is melting and the effect is
halocegenic. Unfortunately it’s a tourist mania who are rushing to see that.
Global warming has also become fashionable – businesses are having areas of marketing that deal with global warming and raise consciousness. Eg. British Petroleum allows user to calculate their indivdual carbon emissions in China and gives them tips to reduce them.
Definition of Global Warming.
Global warming is the increase in the average temperature of the Earth's near-surface air and oceans in recent decades and its projected continuation.
The global average air temperature near the Earth's surface rose 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the 100 years ending in 2005.[1] The Intergovernmental Panel on Climate Change (IPCC) concludes "most of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations"[1] via the greenhouse effect. Natural phenomena such as solar variation combined with volcanoes probably had a small warming effect from pre-industrial times to 1950 and a small cooling effect from 1950 onward.[2][3] These basic conclusions have been endorsed by at least 30 scientific societies and academies of science,[4] including all of the national academies of science of the major industrialized countries.[5][6][7] While individual scientists have voiced disagreement with some findings of the IPCC,[8]the overwhelming majority of scientists working on climate change agree with the IPCC's main conclusions.[9][10]
Climate model projections summarized by the IPCC indicate that average global surface temperature will likely rise a further1.1 to 6.4 °C (2.0 to 11.5 °F) during the 21st century.[1] The range of values results from the use of differing scenarios of futuregreenhouse gas emissions as well as models with differing climate sensitivity. Although most studies focus on the period up to 2100, warming and sea level rise are expected to continue for more than a thousand years even if greenhouse gas levels are stabilized. The delay in reaching equilibrium is a result of the large heat capacity of the oceans.[1]
Increasing global temperature will cause sea level to rise, and is expected to increase the intensity of extreme weather events and to change the amount and pattern of precipitation. Other effects of global warming include changes in agricultural yields, trade routes,glacier retreat, species extinctions and increases in the ranges of disease vectors.
Remaining scientific uncertainties include the amount of warming expected in the future, and how warming and related changes will vary from region to region around the globe. Most national governments have signed and ratified the Kyoto Protocol aimed at reducing greenhouse gas emissions, but there is ongoing political and public debate worldwide regarding what, if any, action should be taken to reduce or reverse future warming or to adapt to its expected consequences.
