7 Gambar Mengerikan Akibat Global Warming

Mungkin kampanye anti global warming di negera kita saat ini sudah mulai surut. Kita telah sibuk mengurusi masalah-masalah yang terjadi di negara kita akhir-akhir ini. Sebagai blogger, kitapun juga jarang mengkampanyekan tentang bahaya-bahaya yang ada di depan kita. Yach… GLOBAL WARMING, seberapa peduli kita dengan hal itu?? Kita menjadi cenderung egois dengan kesibukan kita. Coba toleh di sekeliling kita.. sudahkan kita ikut menyelamatkan lingkungan kita dari perubahan iklim?
Gambar-gambar ini memang untuk membuat kita sedikit “ndredek” atau nervous. Hanya untuk menginspirasi kita untuk bekerja lebih keras menghindari bencana-bencana yang sangat-sangat mungkin terjadi di depan kita.

Salah satu tanda dari global warming adalah : beruang kutub menghilang dari habitatnya. Itu sangat menyeramkan sebab beruang kutub memberikan tanda kepada kita bahwa perubahan iklim tengah terjadi.

Ikan-ikan juga mati karena global warming.

Angin badai. Kita tau bahwa angin badai terjadi akibat perubahan iklim, khususnya di atlantic. Ini terror dari global warming yang dapat menghancurkan rumah dan keluarga kita.

Gletser di Patagonia, Argentina tahun 1928. Gletser di Patagonia, Argentina 2004. 76 tahun dari perubahan iklim. Dan sekarang… menyeramkan sekali.

Iklan global warming?

Badai debu terjadi lebih sering di afrika selatan.

Gambar di atas adalah air terjun besar yang muncul dari ujung Gletser Brasvell. Tidak biasa hal itu terjadi. Air terjun seperti ini telah muncul dengan frekuensi berkala di daerah arctic. Setelah semua itu, ketika abad-lama telah mulai pencairan es di Arctic, sulit untuk menyangkal diri kita bahwa kita telah mendapat masalah besar.

Global warming -- more caused by human activity

NEW YORK: A study by a team of scientists led by NASA climatologist James
Hansen has found that the unusual magnitude of the global warming trend
experienced could not be explained by natural is responsible.

Hansen and his team of 14, all from NASA, Columbia and the Department of
Energy, had co-authored the study reported in the journal Science.

Hansen's team said global temperatures will rise 1 degree Fahrenheit this
century even if greenhouse gases are capped tomorrow.

However, if carbon dioxide and other heat-trapping emissions instead
continue to grow, as expected, things could spin "out of our control,"
especially as ocean levels rise from melting Greenland and Antarctic ice
sheets. 

Experts predict a 10-degree leap in Fahrenheit readings in such a scenario.

The researchers measured Earth's energy imbalance because of more precise
ocean readings collected by 1,800 technology-packed floats deployed in seas
worldwide beginning in 2000, in an international monitoring effort called
Argo. The robots regularly dive as much as a mile undersea to take
temperature and other readings. They found that for every square meter of
surface area, the planet is absorbing almost one watt more of the sun's
energy than it is radiating back to space as heat. This absorbed energy will
steadily warm the atmosphere.

The new temperature readings from the deep ocean trace a clear warming trend
that seems impossible to turn around any time soon. 

Hansen said in a summary of the report: "This energy imbalance is the
'smoking gun' that we have been looking for. The magnitude of the imbalance
agrees with what we calculated using known climate forcing agents, which are
dominated by increasing human-made greenhouse gases. There can no longer be
substantial doubt that human-made gases are the cause of most observed
warming."

Hansen, director of NASA's Goddard Institute for Space Studies at the
Columbia University Earth Institute, said the delayed consequences of past
or current greenhouse gas emissions is due to the "thermal inertia" of the
planet, an effect most noticeable at the ocean's edge when the morning sun
begins to warm sand while the water remains seemingly unaffected. It takes
more of the sunlight's energy to penetrate into the water, particularly at
its lowest depths, than it takes to warm a shallow bit of land.

Scientists still debate how serious the problem is and what could be the
antidotes. The Bush administration has resisted request to limit greenhouse
gas emissions saying more research is needed.

Hansen confirmed that global warming is real, and scientists are now able to
calculate within an acceptable range of uncertainty how much the planet's
retained energy balance is increasing. By their reckoning, the "net forcing"
works out to mean that about 0.85 watts per square meter is being retained
by the Earth -- a seemingly tiny amount compared to the nearly 250 watts per
square meter coming in from the Sun.
