The talk on climate change that needs to be had, whether you believe or not.

Said it before. Biggest contribution is population growth rather than population balance...

Too many people on the rock will be a greater problem than the emissions of each individual currently.

Yeah, everyone has an opinion.Doesn't mean they are right. Population growth and individual emissions sort of go hand in hand. Hard to have one without the other, the time may come when climate change gets to a stage where we can't make enough food to feed the population. That's when it will get interesting. Future generations may not think much of us, I'm afraid.

In a world that is supposedly getting hotter, how do they explain this:

Sea ice surrounding Antarctica reached a new record high extent this year, covering more of the southern oceans than it has since scientists began a long-term satellite record to map sea ice extent in the late 1970s

in 2105, they've recorded the largest size of Antarctic ice sheet ever, since they started recording it in the 1970s .. and this is when global warming has really started to kick in.

the science doesn't lie!

.... and how do they explain it?

?The Antarctic sea ice is one of those areas where things have not gone entirely as expected. So it's natural for scientists to ask, ?OK, this isn't what we expected, now how can we explain it???

What they're saying here is .. we don't really understand what's going on!

So, the folks that we're relying on to explain to us what's happening to the climate, don't really understand what's happening to the climate!

That they do, and like farming land the Earth as a whole only has finite resources.


Even if we reduce emissions (avg) per capita by 50% now and sustain that (per capita), in less than 50 years the population will be producing the same levels we are currently. Considering the current level is considered toxic to the planet by many - this strongly suggests that we are breeding ourselves out of existence.



That's not even taking into consideration food requirements, further improvement in medical (and life extension), housing and resource requirements....

I'd suggest we as a species will soon go the way of the Dodo if we don't modify our thinking..

[bob10]

Yes, a depressing thought. With our anti-biotics becoming less effective I often wonder if Nature, or whatever we want to call it, will step in with a major pandemic to cull a few billion humans. Or some mad scientist [ terrorist?] will develop a virus, to do the job. A LA " the twelve monkeys". Not worth thinking about, time to lose myself in some mindless realty TV show.

Actually they can explain it. The last three years in a row have been the hottest on record ever. What's happening in the arctic, and North America for that matter is that weather patterns have shifted due to global warming. This allows cooler air to move south (in americas case) and whichever way it's moved in Antartica over areas it generally isn't. What you'll find if you do your research is that global warming is occurring and that a biproduct of it is weather instability. This means that areas that are cold can shift around where they wouldn't have before (case in point) and that we will continue to see more and more extreme weather events moving forward.

So in summary, even if there is more sheet ice in Antartica or a colder winter than normal in the USA, on the whole, the entire globe mean temperature is increasing.

Here's a real nerd explaining it http://www.sciencemag.org/news/2012/...winter-cooling
