global warming - it's real, dummies!

William. These AGW people on here are either people persuaded by the authority of mainstream media memes or shills who may be benefiting from the AGW nonsense. They are immune to reason but have a fantastic stamina for trotting out straw-men and ad hominems.

Polar bear populations have dropped drastically in the last 100 years,because of man made global warming.

Forty percent. That’s the stunning population loss for polar bears in the southern Beaufort Sea. The news comes from a new study linking the dramatic decline in this polar bear subpopulation in northeast Alaska and Canada to a loss of sea ice due to climate change.

How does climate change affect polar bears so dramatically? Polar bears rely on sea ice to access the seals that are their primary source of food as well as to rest and breed. With less sea ice every year, polar bears and many other ice-dependent creatures are at risk.

Today’s study, published in Ecological Applications, analyzed data on polar bears in northeast Alaska and the Northwest Territories and documented a 40 percent population loss between 2001-2010 from 1,500 to 900 bears.

An urgent need to address climate change

Climate change is the main threat facing polar bears. But we also know the effects are being seen around the world. Now is the time we must speak up and demand global action.

“This is a clear warning sign of the impact a warming Arctic has on ice-dependent species like the polar bear,” said Dr. Pete Ewins, WWF’s Senior Species Officer in Canada. “Given this subpopulation is at the edge of the range, it’s no surprise to see this happening so soon.”

Added Margaret Williams,  Managing Director of WWF’s Arctic Program, “Here are concrete numbers to show us that the impacts of climate change are happening now. We need to change course if we want to stop further habitat loss and ensure resilient wildlife populations, both in the Arctic and around the world.”

Yes William - it would seem nuts if you have no understanding of what you are talking about. I'm no expert but at least I understand the basics. And no Ziggy - I'm not a shill - I just have an opinion like everyone else. Except mine is based on data and the years of research and understanding of experts who are not politically motivated but seek the truth about an issue.

Your opinion has no data to back it up - just some vague theories by people who are either politically or financially motivated. 

Big oil is not corrupt. The CEO and senior execs have a duty to their shareholders to maximise profits. If they don't do that they get replaced. That is why governments have to have the ability to control the bigger picture. Same as how tobacco companies are not allowed to advertise at sporting events or childrens tv progs, For the future health of the nations governments have to have some power over corporate interests. Even most dyed in the wool conservatives agree this is so. If you don't agree then it's an indication you have extremist views. 

Anyone here who hasn't read William Jevons' treatise "The Coal Question" really needs to.  The harm in capping CO2 emissions is that it would enslave all mankind, and that's too high a price, no matter how good the weather is.  The problem with alternative energy is the same as it was in 1865 (I wouldn't believe this, either, if I hadn't read the book, but I have, so I know).

Also on the point of Jevons, it's sunspots, it's always been sunspots, and it will always be sunspots.  You can actually SEE the 11-year sunspot cycle on the chart at the start of this thread.  The late 20th century is known to be the most active solar activity period in the last 8,000 years, and these sorts of events have always been associated with global warming around this magnitude.

The problem with the science (besides the fact that it's state-sponsored for purposes of state-empowerment) of Anthropomorphic Global Warming (AGW) is that is makes numerous assumptions that don't hold up to even the smallest amount of scrutiny.  For example, the "climate models" are radiative-dominated, but the primary mode of heat loss from Earth's surface is convective.  The water cycle alone accounts for 70%.  The other problem is that their one "positive feedback", planetary albedo (surface reflectivity) is linear, countered by two quadratic (second order, namely convection and conduction) and one fourth-power (radiative) NEGATIVE FEEDBACKS.  As we all know, higher-order modes dominate as temperatures rise, so the warming potential is very limited, even failing to account for the fact that open polar ocean (the vogue scare tactic of the day) is MORE REFLECTIVE than sea ice, because the sun angle is always low in the high latitudes.  This is a negative feedback to climate change being PURPOSELY misrepresented as a positive feedback.

Don't take other people's word for it.  Learn the science for yourself.  There's plenty of garbage being thrown around on both sides of this argument, but if everyone's full of it (and by and large, they are), it's a lot better not to side with the folks trying to enslave humanity (and that's the AGW folks, sorry to say).

William Jevons wanted to find a way to limit fossil fuel consumption, too, for much the same reasons we're talking about today.  However, after taking a hard look at all of the facts, he had no choice but to conclude that any government action independent of free market forces would ultimately be ineffective, and would do mankind untold harm in addition.  But again, don't take my word for it - read his book.

@Dsmith you are using a book published in 1865 to criticise modern knowledge and understanding. 'Bout says it all really.

At that time it was not known that warming would be a problem - faced with current knowledge Jevons might well have a different view. In fact you are being dishonest by saying the Coal Question was anything to do with AGW. Really his main concern was that coal might run out - and that didn't exactly pan out did it?

And your sunspots speculation is just incorrect as well. 

big oil is definitely corrupt, and ceo's have no duty to maximize profit if it means committing fraud. william, you have no clue what you are talking about. do you think you can do brain surgery? play better than magnus? why on earth would you think you know more than experts in a field? no, a carbon tax that is revenue neutral doesn't make anybody rich. really, you spout so much nonsense it's hard to keep up with it.

Humans do add to emissions via both upper and lower body activity, however the amounts are not considered all that significant when viewed against our 'supply and support' issues. Land clearance, dwellings, agriculture, livestock, infrastructure, transport.

Vegans cause global warming by playing smositional chess.

We are the informed world, representing those with relevant education and understanding, and in agreement with 200 governments representing the entire world in their acceptance of the objective facts in Paris in 2015.

The day to be one of the slow, elderly people who express doubt based on understanding that is 50 years out of date (or a total lack of it) is not now.

Unfortunately, the two countries (perhaps) most responsible for the global multilateral system for the past 150 years (UK, and USA) are now led by governments that have clearly STEPPED BACK from their (mostly) hegemonic roles.

Here's an outstanding article in PS today, by a former Foreign Minister of Israel.  I believe you will like it --

Best Wishes on the continuation of your (essentially) Public Interest thread on GCC.  

Thanks - much appreciated. I am confident the US will get firmly back on board before too long: a large majority of the population accept the scientific facts these days and progress was good up to 2016.

LOL, just because the population accept the facts doesn't mean that politicians do. Just look at what Trump is planning you'll see that we are doomed. All those pundits in the universities are just satisfied with sitting inside their laboratories without stepping out of their caves and fighting for their cause.

We're doomed. That's it.
