Sure, there are going to be mediating forces in the environment. Melting is an obvious one. The positive feedbacks have been getting the most attention because they are really scary. It appears that there are gas clathrates in the ground and under water that can come out at a certain temperature. The worst case is that we get an event similar to Lake Nyos, but with a somewhat different mechanism and potentially many more dead. The best case is a significant atmospheric input of CO2 and methane that we can't control.
I don't think I have to discount Trenberth. He's trying to correct his model, he isn't saying there is no warming.
I find this offensive?
We're spending science mind power, money and time researching a way to make a drug that replaces a persons weakness of character and lack of willpower. If you want to stop smoking, just stop. Don't buy cigarettes.
I feel that our culture is sliding away from any concept of holding people personally responsible for their own choices. If a person smokes, overeats, under-exercises - those are their choices. They must be held accountable.
Aside from the crass pragmatists' "Well, I bet I can develop a drug that compensates for weakness of character and lack of willpower faster than most of the population can develop strength of character and lots of willpower..." Why does this bother you?
Is there evidence that people actually develop more willpower(rather than just smoking more) when these 'replacements' are available? If there isn't, surely reduction in smoking related mortality is a win regardless of willpower, and even if there is; exactly how many people of weak character are on the acceptable losses list?
On the more theoretical side, would you condemn a drug that was actually a general-purpose willpower simulant? That actually gave the person taking it all the changes associated with 'strong will' while it is in their system? Or would you consider that to be a great breakthrough, a drug that produces a highly valuable personality trait?
Thanks.
McKitrick is an economist out of his field. Trenberth and Fasullo cite many of their other papers and the publications to which they were submitted, but it seems mostly not accepted. But their conclusion seems to be that there were other times in recent years that the rate of warming decreased for a time only for it to return to its previous rate. I only see the abstract for Kosaka and Xie, but they state "the multi-decadal warming trend is very likely to continue with greenhouse gas increase."
No number is larger than any other number. Quantities are larger than other quantities. Numbers are symbolic entities that can represent a quantity, or not.
I imagine that the major financial companies make this part of their economic modeling. Most of them do publish weather-related and climate-related advisories regarding commodity and company price trends, etc. How detailed do they get? The wouldn't tell and I am the wrong kind of scientist to ask. Can we make a government or public one? Yes, the level of detail is the big question.
Oh, do I have to qualify that for you, like the hottest outside of a period of Milankovitch Forcing? Gee, maybe the Earth's orbit changed, like back then, and we just didn't notice.
Let's take a look at one of the references you cited:
A section of a draft IPCC report, looking at short-term trends, says temperatures are likely to be 0.4 to 1.0 degree Celsius (0.7-1.8F) warmer from 2016-35 than in the two decades to 2005. Rain and snow may increase in areas that already have high precipitation and decline in areas with scarcity, it says.
It sounds like we have reason to be alarmed.
Well, I am trying to get through to you. You wrote that the hiatus was widely acknowledged by scientists! It's like talking with someone who believes in god - they have no facts, and no facts will convince them, and they create their own "science" which is nothing of the sort to bolster their viewpoint. So, I tried another another argument. But let's go back to the first. Nobody credible believes in a hiatus.
Calling names isn't going to advance your argument.
Orbital models only have two variables when there are two bodies. In reality we are always dealing with an n-body problem. Regarding atmospheric models, we have weather, which is too chaotic to forecast, and climate, which should not be.
We could sit back 100 years and see what is happening then, so that we have lots of good data points, but potentially at the cost of widespread famine, death, etc.
We have excellent reasons to stop releasing sequestered carbon even if we ignore global warming.
