They found evidence of a constant decrease in populations over thousands of years, without a corresponding climatic change. It is possible, or perhaps likely that a event like that finished them off. But something other than climate change pushed these local populations to the brink first, and it started at the same time as humans showed up.

Not sure who the "they" you refer to is. In the US EPA cares, the have CAFE standards, and the Estimated fuel economy is used to calculate the allowed CO2 emissions per mile. Other emissions are not directly tied to fuel economy, but hitting the above standard closes the loop.

Sorry boss, despite your arrogance and confidence, your more wrong than right. I have done SAE brake certifications for off and on road vehicles. Most vehicles probably could not be brought to a complete stop from speed if they engine was at full power by brakes alone. The 2 problem are: 1) the brakes do not have sufficient cooling, the engine/transmission have much better cooling, and thus can produce power for a longer time period. Most brakes cannot sustain high power for more than a minute before fading, and will eventually fail all together. Also (for most vehicles) the brakes do not have the same mechanical advantage, since they are at the wheels, and do not have a gear reduction. They apply a fixed maximum torque, at 60 MPH my pickups brakes could produce 800 HP in braking force, but at 10 MPH that would be closer to 100 HP. My trucks engine can easily produce 250 HP at the rear wheels, down to about 5 mph, due to it having real low gearing for towing. If in my pickup the brakes came on full at 70 mph at full throttle, it would take a fairly long stop to get down to 15- 25 mph or so before they would equallize, until the brakes faded and failed, then It would accelerate again. This balance will vary widely based on the power and gearing of the vehicle, but most cars would be pretty iffy on if they could be brought to a complete stop, almost all would slow to fairly slow speed though. Of course at these low speeds, it wouldn't take much outside force to stop the vehicle.

Personally I think it is a series of logical steps that lead to why permitting should be better. The first question is should UBER be treated differently than other companies (smaller and larger.) If no, then next question:
Should anyone be able to test autonomous and driver aids mixed with public traffic? IE can I setup a LLC have it borrow some money to buy some cars, and get the licensed in registered in the cheapest state to get minimal liability insurance through some bonds on a few cars, and start sending people in traffic testing, and acting as a taxi service accepting money from Californians.
If the answer to both of them is no, then oversight is needed, and the next logical question to ask, is should the California taxpayers pay for this oversight, or should it be payed for by the companies standing to directly profit from it?

Regardless the answers to those questions, it is still best for expectations to be set, to avoid unnecessary risks. If we have rules setup for the testing of a inherently dangerous task, which driving cars qualifies as, then it helps both the company, and the public, and the customers to have a decent set of rules set. IE if UBER follows a set of rules developed by a governing body, they are more likely to win a lawsuit against them by showing that. If they follow those rules, they public and customers are less likely to be injured or otherwise suffer a loss. If UBER sets it's own rules, they alone assume the blame for any holes in those rules.

If that is not what California has done for UBER, and the state. Then UBER should be making that case, not the case that they are allowed to do whatever they want in the sandbox that is California.

I did detect a bit of sarcasm in your post. But clearly it is about keeping a base that is controlled by christian leaders.

Conservatives want the church to be in charge of sex, and sex education. Their goal isn't to reduce casual sex, abortion, etc. The goal is that those remain a sin with punishments, that you feel the need to go to church and ask for forgiveness and tithe; That people see their personal happiness are in the hands of the church (provided by/in charge.) That will give the strongest connection to religion, and the easiest to suppress and manipulate. If they allow science to drive sex education and to remove the punishments, and social media to take over socialization, then christian churches and the republican base will not be strong.

I am for solar subsidies, but danbert8 did already respond to OP with how the numbers you used are being misrepresented. Almost all of the "trillion in subsidies" to oil is subsidies to customers, tax free diesiel for farmers, oil bought for our national defense for the petroleum reserve, tax breaks for other customers based on their oil consumption. This drives up the cost of oil, which does benefit big oil indirectly. Where as the Solar subsidies are direct to producers, to lower the cost of solar. So if we did away with the oil subsidies, the price of oil would go down making it more competitive to solar. Where as the solar subsidies drive the price of solar down, making it more competitive.

That is interesting, for a short enough article, a single comma or letter can switch a article from true to false. Similar with a photo, it will likely match a photo edited to turn a fist into a flip off, or a mirror to make the left hand salute vs right hand, added a nip slip...

Get your edit close enough to be a match, and you'll ride the positive Karma from the original, or bring the original down with your falsified one.Then again it isn't all that difficult with any single hash, to make a collision as well.

First show me where the article or I said that. It is a read hearing, neither I nor the article said climate change caused anything, let alone a specific act.

Horrible shit happens in War. War is more likely to happen, when you have millions of people who cannot feed their families because crops are gone, clean water is not available and the food they had bought in the past is too expensive and thus out of reach. You cannot tell me in that situation, it isn't more likely for a warlord with food, money, and smooth talk to get a army together of those people to further his agenda? Pre-existing problems that may have lead to war without a major drought, but with time could have found another outlet, it boils up faster and larger when more heat is applied.

>No matter where you stand on climate change, linking it to the above is more than a bit of a stretch.

Likely your bias contributed to your reading into this a claim never made, and that is that all climate change = Man made Global warming. Some are related, but if you re-read this article with that difference in mind, it is then true. That small localized changes will get worse as the world gets hotter is made more important by understanding how vulnerable the world is to small changes in local climates.

I think too many people just don't get that ag societies still exist, and need to be informed that it often doesn't take much to trigger a flare up when you have so many people living in poverty. It may be wrong to conflate climate change of the past (regional droughts, water shortages, poor crops due to weather variations.) as closely with man made global warming, as this article hints. But it would be difficult or impossible to say localized climate change didn't contribute some to all of those uprisings.

During the same time Women went from 20% employed rate to 60% employed. So we have 50% more of the population working than we had in the 1900's, so really we have only reduced the average working hours by 4 hours per week. We went from (60 hours * 40% working) = 24hours to (33 * 60%) = 20 hours worked per week/person today. Granted because of washing machines, running water, efficient grocery stores...

I really don't think that was as bad as the people taken down on her behalf. Her campaign ran a very negative campaign against Obama and his supporters, and although she did support Obama after, the olive branch was from Obama to Hillary supporters not the other. Her campaign was then very nasty to Sanders and his supporters, and again Sanders put out the olive branch not Hillary, She then attacked not just Trump, but his supporters. She was also very demeaning on the issues found, "I told you so", "see nothing illegal", "blame the Russians for bringing it forward". Oh DWS was irresponsible, out her on my campaign instead....

A little googling gives more questions than answers on that one. Most fatal accidents are at night or at intersections. Seams most minor accidents are close to home or in parking lots. Seams like the drowsy driver and missed traffic control would be covered today by Tesla type system (many equal variants from Ford and GM). The auto system will likely have issues with detecting slick roads, construction, pedestrian interactions. So I would estimate a hybrid system, where we hand off the monotony of driving to the Tesla system. Then get around, with some sensor help the dense areas would save the lives. Full autonomy might not do as much, at least to save lives, but might pay off if in other ways, if it improves efficiency of driving to have fewer traffic jams, and minor accidents.
