So how much was the actual global sea-level rise in the past 10 years and how does it relate to previous estimates?

Current estimates, before this finding, are that it's rising by about 3mm/year, up from an average of 1-2mm/year for the previous century. About 55% of that is estimated to be due to continental ice melt and 30% to thermal expansion of the oceans.

To be clear, the 2m increase is the analyzed 95th percentile (very high end) of the estimates of this meta-study, when you take both glacial melt and glacial expansion. The median values for low and high estimates are 69cm and 110cm. Not that this isn't still terrifying, worth of action, worthy of international collaboration, and so on. Just let's be accurate about our titles.

Doesn’t Earth’s being a spinning oblong sphere mean some places will experience only minimal change while others will see significant change? So all this is “average” rise.

It's a much more complicated process (e.g. the weight of the ice changes the shape of the mantle). The Verge did a good high level overview of some of the different factors in play here: https://www.youtube.com/watch?v=SA5zh3yG_-0

If you're interested in getting involved in addressing climate change, here are two options for citizens to get involved: 1) The Citizens Climate Climate Lobby has been around ten years, and it currently has a bill in Congress that has bipartisan (1 Republican) support: The Energy Innovation and Carbon Dividend Act ( http://energyinnovationact.org/ ). With this plan, all the revenue from a carbon tax* is directly ret…

Aren't they strongly anti-nuclear? Putting science behind ideology is not a very good position to take about climate change.

Anything more I can do to support that bill? Both my reps are sponsors

Are humans advanced enough to engineer around sea rise and temperature changes?

Humanity should be fine. The problem is how to deal with millions of displaced people. We will probably need a few wars to figure that one out.

When is the next US election due? We might need a new administration to get moving on this one. You know... Before we're all fucked.

The cynic in me has wondered the past couple days whether all this new climate change coverage is a full-court press by Democrats in anticipation of the next election. Seems to have become a hot topic in the news just within the past few weeks.

This is speculation not actual scientifically demonstrated furthermore it's speculation based on the most catastrophic predictions.

On top of that, sea-level rise is not some even distribution around the globe, some places will get more others will get less. It's a very local phenomenon.

This is so misleading yet this level of inaccurate reporting is the basis for the current political debate.

Meta studies are to often used as political tools NOT science.

I 10 years when the climate catastrophism hopefully have subdued we will se a host of lawsuits against the words offenders of this scaremongering and "cry wolf"

Yes the climate is changing yes it's getting slightly hotter.

No there isn't any scientifically demonstrated consequences of climate change we don't know how to deal with.

Not to hijack this thread but does anybody know of a list of companies/start-ups who are trying to combat climate change/protecting the environment especially if they are hiring?

With a brother who has a master's specialising in glacier reduction (and a keen interest in data science) he is finding it a demoralising experience looking for companies who actually seem to be taking action.
