While cats have taken a high toll on many bird populations, the leading cause of death is still collisions with glass windows.

Maybe, if we put a picture of a cat in the window, birds will steer away.

In-line comment
The HadCM3 result is inherent, explicable, and applies to virtually all GCMs. Nic (Lewis) identified it precisely, a negative lapse rate feedback ( humidity as a function of altitude). AR4 WG1 black box 8.1 is clear about constant UTrH. That means there is no lapse rate feedback. Yet multiple observation methods have shown UTrH declined with warming. That is an observed negative lapse rate feedback. Upshot is positive water vapor feedback is overstated and the model runs too hot. So it gets artificially cooled to match past history by overstating observed aerosols. When that proved observationally incorrect, the Trenberth hidden heat nonsense emerged to paper over this fundamental GCM flaw.
Lindzen hypothesized the physical mechanism back in 2001 as an 'adaptive iris'. More warmth, more surface humidity, more tropical convection (thunderstorms). These produce more precipitation, which removes humidity that would otherwise reach the UT. Also release more latent heat to radiate away as OLR. A classic negative feedback mechanism damping any warming effect, including (shown in the 1990s) La Nina. Explains the lack of an actual equatorial troposphere hotspot that the CMIP3 archive all model. Problem is inherent and insoluble, since the best supercomputers do not enable sufficiently small grid scales to model these convection cells. The impossibility of adequately reflecting this climate fundamental is probably not something MET modelers would want to admit, lest they risk defunding. Yet AR5 SOD itself acknowledged the problem in WG1 at 7.2.1.2 with respect to clouds generally ( and cloud feedback generally), for which Lindzens adaptive iris is a special and doubly important case because it also produces the negative lapse rate feedback.

They recognise the global warming pause first reported by The Mail on Sunday last year is real and concede that their computer models did not predict it. But they cannot explain why world average temperatures have not shown any statistically significant increase since 1997.
The IPCC admits that while computer models forecast a decline in Antarctic sea ice, it has actually grown to a new record high. Again, the IPCC cannot say why.
One of the reports own authors, Professor Myles Allen, the director of Oxford Universitys Climate Research Network, last night said this should be the last IPCC assessment accusing its cumbersome production process of misrepresenting how science works.
Despite the many scientific uncertainties disclosed by the leaked report, it nonetheless draws familiar, apocalyptic conclusions insisting that the IPCC is more confident than ever that global warming is mainly humans fault.
It says the world will continue to warm catastrophically unless there is drastic action to curb greenhouse gases with big rises in sea level, floods, droughts and the disappearance of the Arctic icecap.
Last night Professor Judith Curry, head of climate science at Georgia Institute of Technology in Atlanta, said the leaked summary showed that the science is clearly not settled, and is in a state of flux.
For example, in the new report, the IPCC says it is extremely likely 95 per cent certain that human influence caused more than half the temperature rises from 1951 to 2010, up from very confident 90 per cent certain in 2007.
Prof Curry said: This is incomprehensible to me adding that the IPCC projections are overconfident, especially given the reports admitted areas of doubt.

(Recall that according to the (model) "projections" the poles will exhibit accelerated warming due to [CO2] increases.)
Well, the Arctic must be REALLY hotting up then, surely?

If the cooling "trend" at the end of that curve continues....we may all need to invest in snow shovels.

It won't be at all surprising if we soon start to see more droughts as well as more floods.

Even the limited historical data that we have shows that current floods and droughts (and other extreme weather events) are well within the natural variation of the climate system. That we affect local environments is clear and UHI is a classic example. That we are able to render the environment unsuitable for our own purposes (radiation, pollution etc.) plays to our other trait of short-sightedness. But at least those effects are measurable and can be defined and analyzed.
As for [CO2] and its power to overwhelm the planetary climate system, other forces are in play and they, too, come directly from our foibles. The science and data clearly show it not to be an issue of any import.

When most of your topsoil has washed out into the Gulf of Mexico and most of what's left is so salted from artificial fertilizers that it can no longer grow anything, and that combines with drought because all the rain that falls cannot recharge the aquifers because it runs off and/or evaporates too quickly it's going to be a bit difficult to provide the food and water required.
That doesn't even address the certainty (it's already occurred) of pests and diseases becoming immune to ever more virulent poisons..which humans may well not adapt so quickly to handle..and causing havoc in crops with the same genetic makeup. It's basically the Irish potato famine scenario as genetic diversity in food crops is being ever more restricted and constrained.
This isn't because we have too many people but because we have a stupidly destructive way of managing food production and water use.

I understand this is your bias and your main theme in all of your posts.
I just think stupidly destructive is a step too far but ok.
I encourage you to post improvements, as you try......thank you.
The world is better off with critics ......thank you.

The disease/immunity response has been in ploy since the beginning of time. Disease attacks (and kills) the most vulnerable. Those with the greatest immunity survive, and pass on their immunity to following generations. Diseases must mutate, in order to survive. Nature selects those most capable of survival, and so on.
Similar genetic makeup in any species is a recipe for disaster. In-breeding among plants and animals can have devasting effects. This has always occurred, and is no mroe or less common today than in past eras.

One of the cooler periods, famines often occur during the years when growing seasons are short and the resulting agricultural productivity is low.

Sorry, you are wrong. There are already governments actively restricting the sale and use of seed which is not "registered" and in some countries it is now illegal to sell, trade or even give away seeds not on that list. Farmers who try to raise crops from canola or corn or soybeans which are not genetically modified had better have their own markets as Monsanto and their cohorts now own the companies which buy these commodities and they can - and usually do - simply "not have a market" for such that don't come from their seed.
Farmers in Canada tried to prevent the admission of GMO flax for this very reason, but the government denied them, so now the farmers are pretty much forced to grow GMO flax. Farmers are not allowed to sell even grass seed as "common" seed anymore, it has to be of a registered variety or they are subject to prosecution. There is even a notice to that effect in the advertisement section of the major farming newspaper.
Farmers in Turkey I am told, can not only have their crops destroyed (at their cost) if they are growing an unregistered crop, but also even if that crop is registered but in the wrong field. I bought some seeds from Britain a few years back and was charged a penny to join a "club" as that was the only way they had found to circumvent the rules about selling heritage vegetable seed which wasn't on the "list". Thatchers in Britain have now to import thatching straw from Spain as they are no longer allowed to raise their own straw for thatching, those (traditional) varieties are no longer "approved" for Britain.
Inbreeding and wild crossing has indeed always occurred.Of course, in nature the crossing is always between "relatives" - plants or animals with sufficient genetic similarities for offspring to survive Some are not close enough for those to be able to raise the next generation though, such as a cross between a horse and a donkey..the offspring (mules)are almost invariably sterile.
You will not, however, ever naturally find (as an example), a potato with jellyfish genes, which not only now exists, but can reproduce itself. You also won't find plants in nature (for very long, at least) which are genetically coded to be unable to reproduce and we also not only have those, we are forcing farmers to raise them so they cannot save seed and must buy it every year.
The main point though, is that the results of natural crossings either thrived or not according to how well they coped with their environment. This is no longer the case. Plants are genetically spliced and then supported with totally artificial inputs of fertilizers, pesticides, fungicides and herbicides...some crops get hit with up to 9 different sprays in a season. What happens when those things become too expensive or even unavailable, or, as is happening, FAIL? In the past diversity has been a buffer against such things as the Irish potato famine, which occurred because almost everyone in Ireland was growing the same variety of potato. When it got hit with an unexpected blight, it was disaster.
Farmers in South Africa not long ago lost thousands of acres of GMO corn - the general estimates were over 30 % of the total crop that year -because (according to Monsanto) they hadn't been given instructions for sufficient fertilizer to be applied. The corn simply didn't form ears, so there was nothing to harvest.
Some years ago, a similar loss happened in the US when a new blight showed up that was immune to the GMO fungicides. Corn borers have developed an immunity to the poisons which used to kill them so now more virulent ones are being used. There's absolutely no reason to think they will not also develop immunity to those as well, we've been that route with overuse of antibiotics and have managed to develop such things as flesh eating disease as a result.
Virtually all the commercially grown corn soybeans and canola, at the very least, and most of the other major food crops as well, are now GMO varieties which focus on the same traits and rely totally on an artificially supported environment.
There is also growing evidence that the various sprays necessarily used for these crops are implicated in the " bee colony collapse disorder" and of course if we lose the bees for pollinating things then that is also a major disaster, they are an essential link in the production of most of the food we eat.
In the US, the government has given Monsanto at least temporary immunity from lawsuits.
We are deliberately setting up a situation where we are not only limiting diversity but inviting disaster.
I think stupidity is an understatement.

While famines typically occur during cooler periods, where rainfall is light, the great Irish potato famine was due to a disease. While the cooler temperatures that occurred late that summer affected all crops throughtout Europe, the entire potato crop was virtually destroyed, and along with it, over one million Irish. Many like to blame the Irish for their over-reliance on one crop, and one variety of that crop. However, British politics played a large role in the Irish adopting a single crop, especially the English Corn Act. Ireland is not alone; several other countries have adopted single-crop agriculture, and would be susesptible to a similar catastrophe.

Onoway, you state initially that I am wrong, and then everything you say seems to agree with my statement about genetic diversity. Whether natural or artificial is irrelevant; the effect will be the same.
