Need some evidence on Global Warming?

Question

I need evidence on each of these three things:

1) The polar ice caps are melting

2) Climate Changes

3) Species are becoming extinct

Please cite your sources. Thank you.

I will "thumbs up" almost every answer.

Answer 1

Go to the North pole ,watch the ice crunbling into the sea

go to the mountains and look for the glaziers and mountain snow

we are witness to the first mass exstinction of flora and fauna since the days of the dinosaurs

of the earth's estimated 10 million species, 300,000 have vanished in the past 50 years. each years, 3,000 to 30,000 species become extinct.

many animals are becoming sick because of changes in temperature ,

vital links in the food chains are disapearing affecting other species further along in the chain

90% of the feral (wild) bee population in the United States has died out.

Recent studies in the United Kingdom and the Netherlands have shown that bee diversity is down 80 percent in the sites researched,

"bee species are declining or have become extinct in Britain."

the numbers of wildflowers that depend on pollination have dropped by 70 percent.

there is plenty of data on this on the web

do your own surfing

Answer 2

there is a movies available on youtube.com that has evidence of #1 and #3 and maybe #2.

I have had info on my myspace page about global warming.

hope links will help u.

actually do yahoo cause yahoo is so nice with there yahoo answers that I like them much. I got my info from yahoo search :)

Answer 3

1) Hard to find, as they are shrinking in area, but getting thicker in other areas. You need to find total mass not total area figures on the ice caps. (and then, they fluctuate normally anyways, so you need to find those fluctuations)

2) Climate Changes....there is lots of evidence on the Earth's cliamate cycles, from ice ages to warming periods.....

3) Species always become extint, it is survival of the fittest. Can global warming be responsible? Possibly, but probably offset by the number of species that survived because of the climate change.

Answer 4

consult this website. it has evidence of all the indicators and also propsed mitigation measures and adaptation
