Greenland Ice Melt

This one minute video shows how the melting of Greenland's ice cap has increased. If all of this ice melts, as widely prediceted, sea levels will rise 6-7meters and force hundereds of millions of people to move, hence mass migration and security situations made worse due to environmental refugees.








We may still have a chance to avoid this, but actions over the next 10-20 years and longer will be crucial. Commitment to warming will be made on this timescale but depending on ice dynamics the entire melting process could take hundereds, or evena thousand years, recent research suggests that things could be more rapid...whatever the case given the fact that many of the worlds major cities, several countries and a huge ammount of biodiversity is extremely sensitive to sea level we may be advise to reduce the accumulation of greenhouse gasses.

Remember greenhouse gasses typically stay in the atmosphere for a long time and stabilising concentrations at any level requires roughly a 90% cut in emission...the delay largely defines what level we stabilise at.

These images will become more frequent in the future years, due to the emission of gases by industrial states like the U.S.A, China and Russia. The only thing that must be done is the public pressure on these countries because this is the only way to save our precious planet.

I think you are largely right.

However it is not just the industrialised nations. Deforestation in Brazil and Indonesia and associated fires cause a significant qauntity of emissions.

I think the global north is largley reponsible and will have to fund mitigation but virtually all nations will have to be involved.
