Untuk dekade2 mendatang dunia akan dikunjungi oleh lebih banyak, lebih
ganas musibah2 alam ini. Ini sudah di setujui oleh badan dunia yang menghimpun
para ahli dari seluruh dunia untuk memberikan acuan tentang global warming dan
akibat2nya.
Australia yang juga tidak ikut sebagai penandatangan Kyoto-Protocol,
sebaliknya telah mengusahakan adanya pencemaran udara (greenhouse efect).
Walaupun Australia hanya kecil tanggung jawabnya atas pencemaran udara cuman
1.5/2% dari total pencemaran didunia ini, tapi diakui secara per
capita(penduduk sedikit) Australia adalah pencemar yang termasuk paling tinggi.
Usaha Australia saat ini adalah diterapkannya tehnik baru untuk mengolah
batubara agar tidak jadi pencemar greenhouse. Juga untuk mengatasi kekurangan
air, karena benua ini sangat rawan akan air, pengaturan aliran sungai akan
diatur dengan lebih efisien. Pemerintah mengeluarkan dana sebesar A$ 10 milyard.
Juga perdebatan terjadi untuk mulai mendirikan tenaga nuklir untuk nenergi
yang dibutuhkan. De-salinasi dan treating wast water mulai di upayakan.
Dibeberapa state sudah di mulai dengan menghemat air. Hanya 2 kali seminggu
orang boleh menyiram kebun. Cuci mobil dilarang. Pelanggar akan mengalami denda
on the spot sebesar $400.- buat pelanggar pertama.
Bahkan "sampah" seperti asal dari kebun dan kertas dan karton /plastik mulai
dengan berhasil di recycle.
Yang mengkawatirkan tidak saja pulau2 di lautan Pasifik banyak yang akan
tenggelam juga di Bangladesh sudah ada 3 pulau yang ditelan laut, akibat
naiknya permukaan air laut. Es2 di Arctic mulai lumer dengan begitu permukaan
laut naik. Flora dan fauna tidak saja didaratan tapi juga dilautan mengalami
kehancuran. The Great Barrier Reef, tempat aku ber-holiday (scuba diving) 20
tahun mendatang koral2nya akan terjadi pemutihan/mati akibat global warming.
Dari itu bagi negara2 dunia ketiga masa depannya akan burem, apalagi kalau
duit ngak ada(karena korupsi) sehingga global warming akan menerkam lebih
dahsyat lagi. Akibatnya secara pisik negara dan rakyat akan tambah deldel
duwel.

February 2, 08:46 PM UN panel says global warming man-made The UN climate
panel has issued its strongest warning yet that human activities are heating
the planet, adding pressure on governments to do more to combat accelerating
global warming.
The IPCC, the most authoritative group on warming grouping 2,500 scientists
from more than 130 nations, predicted more severe rains, melting glaciers,
droughts, heatwaves and rising sea levels, especially if Antarctica or
Greenland thaw.
The final text said it was "very likely" - or a probability of more than 90
per cent - that human activities led by burning fossil fuels explained most of
the warming in the past 50 years.
That is a toughening from the last report, in 2001, when the IPCC said the
link was "likely", or 66 per cent probable. Signs of change range from drought
in Australia to record high January temperatures in Europe.
"February 2, 2007 may be remembered as the day the question mark was removed
from whether (people) are to blame for climate change," Achim Steiner, the head
of the UN Environment Programme, told a news conference.
He urged governments to inject more momentum into stalled talks on long-term
cuts in emissions. Greenhouse gas levels in the atmosphere have not been higher
in 650,000 years.
"We are in a sense doing things that have not happened in 650,000 years,
based on the scientific evidence," Rajendra Pachauri, the head of the IPCC,
told a news conference.
A 21-page summary of scientific findings for policy makers outlines wrenching
change such as a possible melting of Arctic sea ice in summers by 2100 and says
it is "more likely than not" that greenhouse gases have made tropical cyclones
more intense.
The report predicts a "best estimate" that temperatures would rise by between
1.8 and 4.0 Celsius (3.2 and 7.8 Fahrenheit) in the 21st century, within a
likely range from 1.1 to 6.4 Celsius.
Temperatures rose 0.7 degrees in the 20th century and the 10 hottest years
since records began in the 1850s have been since 1994.
UN officials hope the report will prompt governments - led by the United
States, the top emitter - and companies to do more to cut greenhouse gases,
released mainly by burning fossil fuels in power plants, factories and cars.
Many backers of the UN's Kyoto Protocol, a plan binding 35 industrial nations
to cut emissions of greenhouse gases by 2012, want outsiders to get more
involved. The United States and China are not bound by Kyoto targets.
The head of the US delegation said that President George W. Bush's policies,
braking the rise of emissions rather than cutting them, were working.
"The President has put in place a comprehensive set of policies to address
what he has called the 'serious challenge' of climate change," Sharon Hays,
Associate Director of the White House Office of Science & Technology Policy,
told Reuters.
Bush pulled out of Kyoto in 2001, saying caps would harm the economy and that
Kyoto unfairly omitted developing nations from a first period to 2012. He
focuses instead on big investments in technologies such as hydrogen and
biofuels.
The President of Kiribati, a group of 33 Pacific coral atolls threatened by
rising seas, said time was running out.
"The question is, what can we do now? There's very little we can do about
arresting the process," President Anote Tong said.
The report projects a rise in sea levels of between 18 and 59 centimetres (7
and 23 inches) in the 21st century - and said that bigger gains could not be
ruled out if ice sheets in Antarctica and Greenland thaw.
Some leading scientists had criticised an earlier draft for cutting the range
after the 2001 forecast a rise between 9 and 88 cms by 2100. Rising seas
threaten countries such as Kiribati and cities from Shanghai to Buenos Aires.
