Not that there are no worries, but the worst case scenarios being put forward are almost certainly not accurate. In fact it has been acknowledged that the worst case models submitted to the Paris Climate Accord talks were misleading in their assumptions.

Anyone have a citation or rebuttal for this?

Here is some support, I've been trying to find the original article I read but it was based upon this research team's findings:

https://www.washingtonpost.com/news/energy-environment/wp/20...

Apparently the worst case scenarios mentioned here were used as a focus during the Paris accords.

Walk or bike to your workplace instead of taking the car. Use public transportation. Oh, sorry, I misread what you asked about. You don't want to do something against climate change, you just want to mitigate the effects on you. Best thing is to avoid all those people who will migrate because it doesn't rain anymore in their place so they have to starve because of bad harvests.

You don't want to do something against climate change, you just want to mitigate the effects on you. I've might sounded selfish. Obviously reducing footprint is important, but there are several other factors one can't control. I'm interested in what is the best course of action if push comes to show.

Surround yourself with good and trustworthy people and be good and trustworthy yourself. If the worst case scenario becomes real you will probably not want to be around for it anyway and if you do manage to survive, it won't be alone.

‪What industry is contributing to climate change the most? Where is a good place to find data on this?‬

https://www.epa.gov/ghgemissions/global-greenhouse-gas-emiss... : * Electricity and Heat Production (25% of 2010 global greenhouse gas emissions) * Agriculture, Forestry, and Other Land Use (24% of 2010 global greenhouse gas emissions) * Industry (21% of 2010 global greenhouse gas emissions) * Transportation (14% of 2010 global greenhouse gas emissions) (Top 4 only, accounting for 74% of emissions)

84%?

is it not enough that virtually all credible scientists are warning us of the very bad things we are at risk of? The public perception is that science keeps warning of imminent disasters that keep not happening. Climate profiteers like Al Gore have totally undermined the credibility of science.

I would posit that if Al Gore is all it took for science to have its credibility undermined in your eyes, you don’t actually know what science is, how it works, or much about the issues at hand.

I would posit that if I refer to the public perception and you think I am speaking personally you don’t actually know what reading comprehension is

Too bad we can't create a dyson sphere that we could partially close to limit sun exposure enough to refreeze parts of the planet as needed and also use the sphere to power everything on earth.

This reminds me of the Sun-Earth-L1 Lagrangian point, where we have deployed several spacecrafts: https://en.wikipedia.org/wiki/Lagrangian_point#Spaceflight_a... An international effort could easily deploy reflective materials here to reduce solar radiation on Earth. Though I wonder how much it would cost to achieve even a 0.01% reduction in radiation, as well as what material would be most cost-effective to deploy.

Lametta?

I’m not having a problem reading what you wrote, although I admit that my psychic powers are for crap. In other words, I read what you wrote, not whatever subtle variation you felt. Taking context into account, I suspect that what you actually wrote was pretty much accurate, without the post hoc qualifications.

They said New York would be under water by now, so we took steps back then to limit emissions, and that never came to pass.

Ok, can you provide any sources for that claim?

Are you familiar with CAFE? Or the EPA in general? You were the one who made that statement about New York being underwater. Find me a date and a quote and I'll tell you exactly how things changed afterward.

The point I'm trying to make is that we've already taken steps to limit impact which is why the apocalyptic scenarios of yesteryear haven't come to pass.

Oh please bitcoin doesn’t even approach the carbon emissions of the US military. Nobody ever points that out.

It's certainly not helping to add another, growing source of heat/electricity to the mix.

Question was: what contributes to climate change the most, not what marginal growing source of heat / energy consumption is not helping.

"Scientists in the US have presented one of the most dramatic forecasts yet for the disappearance of Arctic sea ice.

Their latest modelling studies indicate northern polar waters could be ice-free in summers within just 5-6 years.

Professor Wieslaw Maslowski told an American Geophysical Union meeting that previous projections had underestimated the processes now driving ice loss.

Summer melting this year reduced the ice cover to 4.13 million sq km, the smallest ever extent in modern times. Remarkably, this stunning low point was not even incorporated into the model runs of Professor Maslowski and his team, which used data sets from 1979 to 2004 to constrain their future projections.

In the end, it will just melt away quite suddenly Professor Peter Wadhams "Our projection of 2013 for the removal of ice in summer is not accounting for the last two minima, in 2005 and 2007," the researcher from the Naval Postgraduate School, Monterey, California, explained to the BBC. "So given that fact, you can argue that may be our projection of 2013 is already too conservative."
