It should be reasonable to think that removing all that oil should contribute to earthquake frequency?

An earlier post on this thread also raised the issue of whether the increased heat is causing the crust to expand, also leading to increased seismic activity. Interesting questions.

Earthquakes, global warming, zika virus, crazies with AK's !!!

While staying home and worrying may be the latest trend, a thousand miles on two wheels keeps things in perspective.

65% of Americans think climate change / global warming is a medium to big problem. About 60% have thought so since the year 2000.
However the campaign of money and disinformation by the denier lobbyists continues to rule the Republican politicians.

Of course all you 'scientists' know that denier is not a word pertaining to Denying.
Of course you do.

It's okay to call you a Denier... in other words... a Liar. They're on the "right" side of the conversation. Sleazy tactics are okay.

How much of the warming since mid 20 century is due to human influence?

Yes, human activity is likely one of the 31,215 variables involved in global climate change.

...and is the primary cause for most of the warming over the last 50-65 years.

Right, so they've controlled for the 30,000 known variables and the 10,000 others we don't know about.

Not saying they're wrong, but for a system as large and complex as the Earth it seems pretty unlikely they're right on causality. A piece of the puzzle I'd buy but when all this political nonsense has humans at the absolute dead center I question motives.

Making less of a footprint and reducing overall resource consumption makes sense to anyone however.

That's what attribution studies do. They control for the most significant factors. The rest just cause the little wiggles in the graphs and don't contribute to the long term rate.

Yea, I know, if we don't know everything exactly we don't know anything, bla bla bla.

Therein lies the problem that everyone wants to ignore. I suspect most "deniers" simply "feel" that the cure is worse than the disease, but don't want to bother with the difficult analysis of really making a decision. And i suspect that most "believers" simply "feel," by the same process, that the disease is worse than the cure.

Peer review science isn't perfect, but it's probably the best thing we have for difficult scientific issues. The peer review regarding climate change is clear.

If your doctor tells you you have cancer, you ignore that and go with what you "feel". Wait, wut, that's not how you operate??? Gee really???

Additionally, to the extent the science is unknown, most people assume that any scientific error will be on over predicting the problem. But it is just as likely as the science is under predicting the problem.

People freak out about storing a small amount radioactive material and think we need to guarantee the storage is safe for tens of thousands of years. With regard to climate change, it is very difficult to get people to look past the year 2100. Sea level is going to rise 30~50+ feet in the coming centuries. Southern Florida is not a long term option.

Countries, states, counties, cities, businesses, etc. should now be considering how they can adapt to GW. There won't be a world-wide consensus on severe economic measures, so adaptation should be the focus. The idea of a $5 carbon tax/gallon measure would probably push the US into a deep recession. It would be incredibly unfair to the poorest of us while hardly affecting the wealthiest, and for many in this country it would smack of political correctness, something we could do without.

I would push nuclear energy and electric cars.

Winter's are no longer cold enough to kill off the bark beatle. Coupled with no water, trees in this part of the Sierra are dieing fast. If you love the Sierra Pine forrest you may want to see before it all gone. Sad to see it die, to have to cut big old friends down and burn them because no Mills will take them. Nay sayers please consider this. So what if not true, what would a 7% decrease in your daily energy consumption really cost you.

A $5 per gallon revenue neutral tax on fuel is quite livable.
It can be phased in over a few years in increments. It can be offset with other tax decreases like Soc. Sec tax or income tax rates.
It is by far the most simple and effective policy.
The price in California has already been above $5 in todays dollars.

http://www.californiagasprices.com/retail_price_chart.aspx

Reached $4.50 in 2008 , which at 2% inflation for 6 years is $5.07 now.

Such a rate is still far below many other countries.

Now gas is so cheap there is no incentive to conserve, even for low income earners. Look at all the muscle cars and trucks.

Being labeled a 'denier' deny:er, I can only assume all the 'believers' are doing more than wringing hands and shouting out how right they are on internet forums.
There is no denying the facts. Human activity has an effect on our atmosphere. However, the hysteria generated by these home brew scientists is a joke.
Do something of value if you're so inclined, besides preaching that is.

So California already has a gas tax above $5 ? If revenue neutral, then it must be purely the shock value that would keep a car owner from buying gas at $9/gallon.
