Oh my god, the first picture of the Arctic is absolutely stunning, although it shows the ice melting.

I co-founded a foundation and we teach everyone about global warming. Some individuals say that it a farce. We believe it is indeed happening, but exaggerated. Either way it is at least to some extent, and is largely because of deforestation. we try to teach people to spread word that we must plant more trees and never underestimate the relevance and importance of greenery to the earth ecosystem.

Jane,
Not so much. Less volcanic activity than usual in the current period, less sunlight, a La Nina – it SHOULD be cooling, but for global warming (human caused).

I think you missed the point of the article: as the ice on the earth’s surface melts, LESS sunlight is reflected off the earth and the temperature increases in a region (over time). Higher temperatures cause more melting of glaciers and snow on land – which flows back to the ocean – INCREASING sea level

Doc — Estimates of sea level account for sea ice; or better to say, they don’t include it for the very reason you mention. And scientists have already accounted for this; no one is saying Arctic sea ice melt will raise the seas.

Ice situated on land is the problem. The vast majority of the world’s freshwater is tied up in glaciers and ice sheets, particularly in Greenland and Antarctica. When that ice melts and moves off of land, sea level has to rise. See point 13 above.

This article is beyond stupidity. The melting of ice already floating on the seas, regardless how high that ice column is, will not increase sea levels! Why? Its mass already displaces the sea upon which it floats. I cannot believe NASA would allow such idiocy to be posted.

Also, the eruptions alter the sunlight on earth, AND produce the deep colors at sunsets. My understanding is that precipitation needs ‘particles/ dust’. There have been quite a few eruptions in the past 30 years. It seems to me there is less drought now, but a lot of infrastructure on waterways and coasts. Perhaps not so much ‘global warming’ as the causes per se.

Haven’t the volcanic eruptions affected the weather, such as the huge eruption in Iceland last year? Then this past winter there was enormous snowfall….lots of precipitation has occurred. Historically, large eruptions HAVE affected weather patterns for as long as 5 years.

i think we should prepare because the critcal point isn’t when the arctic free from the ice it before, that when it reach 20% or 30% because the ice then can not influnce in the weather by cooling.these mecansim will shutdown then new one will start. So are we preapre.

If it was possible for the entire world to just stop all the fighting and start working together to reduce everything bad we do to the earth, it wouldn’t fix the problem; it was at least help. Just putting in my 2 cents, I have personally been trying to work on my own bad habits, cutting down on trash etc. I don’t even drive. I believe if everyone could work on there way of life, all together it would do some good. There should be a site out there that keeps on updating information on the earth and also infomation and Ideas on what you can personally do to make things better where you live. Anyway, I am a person who loves our earth because I know if it wasn’t for her we wouldn’t exsist and I thank the updated info.
