Global Warming is only just starting now. We are going to be thrown back millions to tens of millions of years to previous climate states. Hopefully not as far back as the Paleocene Eocene Thermal Maximum (PETM) -- at that point the ancestors of horses were only a big as house cats or they would die from heat stroke. Humans are too large and are brains too big to survive in a much warmer world. After our descendants run out of energy for air conditioning, massive sections of the planet will be uninhabitable.
This current streak which is happening because of the recent strong El Niño will back off for a few more years.
It also only looks at atmospheric and surface temps, a lot of energy is being pushed into the ocean. Actually, I think that air warming is happening faster than predicted because ocean mixing is slower than the models.

How can we "run out of energy for air conditioning"? As long as the sun shines, we have more energy than we need; All we have to do is capture it and distribute it to where it is needed - which in the case of a/c is typically in the places where solar energy is most readily available.
We also have enough uranium available to produce as much carbon neutral power as we can use for (at least) several centuries; and we haven't even started on the much larger resource that is thorium. We need to stop burning coal ASAP - and we have the technology to do that pretty quickly, once the political will is there. We also need to stop burning fossil oil and gas, which is less easy to phase out rapidly; But given sufficient clean energy, the technology to make oil from CO2 is pretty simple, and has been used at industrial scale a few times before, notably in Germany during WWII, and in South Africa during the anti-apartheid embargoes. Such 'artificial' hydrocarbons are carbon neutral if burned as fuel - and actually reduce atmospheric CO2 over time, if used to make polymers.
Running out of energy need not be a problem at all. Like global warming, the issue is purely political - as long as there are no economic penalties for externalizing the cost of CO2 emissions onto the rest of humanity, people will continue to do it. And as long as the so called 'environmentalists' maintain their irrational opposition to nuclear power, the burning of coal will continue to be a major source of electricity - and of CO2.

This is a long, but a very calm and detailed presentation on climate change focusing on sea level and ocean warming. Basically over a long period of time the oceans will warm from top to bottom and it is unstoppable. Until the long period of time it takes for CO2 levels to lower there will never be a climate like we have had until now. We are looking at tens of thousands of years. Irreversible on human time scales.

The question is: So what?
You don't understand the science?

The science doesn't answer the question of "so what?".
The science tells us the problems our habitat is facing and also provides ways to mitigate the damage. It should be obvious that this is very useful information.
Trump is going to make American great again by burning more coal.

JonA,
Are you saying that the 13 straight months is meaningless, or that global warming inevitable?

I see you have nothing intelligent to contribute.

At this point, global warming is inevitable but the ultimate rise in temperature is not. Even if humankind stopped emitting any greenhouse gases today, the concentrations in the atmosphere would take too long to fall to avoid some temperature increases.

The "science" that plays fast and loose with the stats ? LOL.
It's never too late to correct your ignorance of climate science, but I don't have high hopes for you.

So for various emission scenarios, what do you think the peak temperature increase is and how long until it comes back down to pre-industrial levels? Anything in the thousand of years should be considered permanent as far as humans are concerned.

The literature is vast and confusing because there are so many different assumptions and policies in the studies. From what I can tell (and I could be very wrong) is that there seems to be a rough consensus that the average world temperature will rise at least 1.5 degrees F without any change in current usage with a more likely increase of 2 to 4 degrees F. Even with mitigation strategies that include putting moderate prices on emissions of carbon (taxes or permits) of $30 per metric tonne, the average temperature increase might be held to under 2 degrees F over the next couple of 100 years.
It's the deniers playing fast and loose with the data.
