Land degradation, rising sea levels, famine, and conflict will continue to drive people from their homes and towards cities, with megacities like Mexico City and Lagos becoming increasingly common in some of the poorest parts of the world.
According to the University of Illinois' Arctic Climate Research Center, global sea ice levels now equal those of 1979.
Is global warming causing more extreme weather events of greater intensity, and is it causing sea levels to rise? The answer to both is an emphatic 'no.'
The last time the world was three degrees warmer than today-which is what we expect later this century-sea levels were 25m higher. So that is what we can look forward to if we don't act soon.
We need to reduce carbon emissions, protect Maine's key industries and preserve our coastlines from flooding and rising sea levels.
Let me state what the official IPCC prediction is: Sea levels could go up as much as three-quarters of a meter in this century, but there is a reasonable probability it could be much higher than that.
Listen, global warming is a real problem, but it' s not the end of the world. A 30-centimetre sea level rise is just not going to bring the world to a standstill, just like it didn't over the last 150 years.
Climate impacts hit working people first, and with extreme weather events, changing seasons, and rising sea levels, whole communities stand on the front lines.
We have no choice: we must protect Arctic ice, enable it to continue to act as an essential temperature regulator for the planet, avoid the catastrophic rise in sea levels that would result from the ice melt, and stop the disappearance of permafrost releasing irreversible quantities of greenhouse gases back into the atmosphere.
I believe that climate change is real, is driven mainly by human activity and that it is driving real-world changes such as extreme weather events, hotter temperatures, rising sea levels and ocean acidification.
Hillary Clinton is listening to the scientists who tell us that - unless we act boldly and transform our energy system in the very near future - there will be more drought, more floods, more acidification of the oceans, more rising sea levels.
People are finally able to look around and say, 'I can see the drought, I can see the rising sea levels, I can see the crops dying. Okay, now I get it.' It is finally beginning to sink in that there has been a lot of damage.
