Yeah, but the economy and things!

Completely hair brained scheme here... but if things get bad enough, could we trigger a minor 'ice age' by blasting enough dust particles into the atmosphere? Maybe buy ourselves a few decades to figure out a more permanent solution?

We already know that major volcanic eruptions and meteor impacts can cause short term decreases in worldwide temperatures because of dust particles high in the atmosphere blocking sunlight. Could this be done in a controlled way, as a temporary solution?

What Nye has to deal with in Congress. Big reason why there is so much fighting of climate change in the house.

There are some theories around injecting sulfur dioxide or water vapour into the upper atmosphere that woul provide cooling. Personally I think some sort of geo-engineering will happen before the necessary cuts in CO2 can occur.

Still doesn't address ocean acidification and could create a whole slew of us intended consequences but is very cheap to do relative to the cost of actually transitioning away from CO2 while brining developing nations out of poverty.

Really interesting article. Thanks for posting this! Kind of cool that the one of the leading experts on this was originally from the UofC also.

Argh, the news cycle has again story about the incoming mini ice age around 20 years from now. Science journalism is so frustrating.

It's not science-journalism, it's anti-science journalism.

[Thor]

That it is! The word science does not belong associated with these journalists. Ben Goldacre has so much ammunition to write his blogs, editorials and books.

Maybe I'm missing what you guys are upset about? This article:
http://www.sciencedaily.com/releases...0709092955.htm
Indicates they have modeled solar activity with 97% accuracy(if only climate models were so good!) that solar activity will fall by 60% during the 2030s to conditions last seen during the 'mini ice age' that began in 1645.

What is anti-science about that?

[troutman]

Are we heading into a new Ice Age?

[Fuzz]

That's not really relevant though as it is discussing a full scale ice age. What the article is saying is that the sun is approaching conditions last seen in previous "min ice ages". They also don't say that Earth will experience those changes, just that the Sun's conditions will be similar, though I would assume the affects on Earth would be similar, though possibly mitigated by higher CO2.

It will be interesting to see what happens with temperatures if the sun does decrease in activity, as the sun has been more active during our modern temperature rise, and we don't seam to be on any path to reduced CO2 emmisions.

That said... I'm sure you're right.

Record cold winter out east in 2015. February in particular set lot temp records in Michigan, Cleveland, Chicago, etc. Also snowfall records were broken in places like Boston and Denver. As good as our winter in Calgary was it was that much worse out east.

74.1 of Americans are obese. Guess that means we've solved world hunger.

Well seeing posters seem to be using Calgary as a measuring stick for global warming.....

It's the reason a lot of people roll their eyes at the pro-Global warming fanatics. Posters go on about Calgary's mild recent weather and it's all good but bring up the fact the east coast of North America had a really cold winter is followed immediately by attack posts.

How so?

We have free energy technologies, they were given to us by extraterrestrial races; they're just tied up in black projects by the American government and will never see the light of day. We'll have to use our brains in the meantime to invent something incredible.

Quick summary here:

- One poster posted a study of worldwide trends conducted by NASA
- Another poster quoted said post six months later and asked how it compared to the historical average
- A third poster responds with a pretty basic post about how it was in Calgary
- In between, a bunch of well-written scientific articles are posted and debated, none of which are linked to anything Calgary-specific
- You come in half-cocked and cherry-pick one pretty irrelevant post in an attempt to discredit everything else

That's why you're getting attacked.

The recent movie "Merchants of Doubt" is well worth a watch on this. Essentially, the playbook here is lifted directly out of the tobacco industry's from 40+ years ago. Everyone knows the information will come out in full eventually, and everyone will eventually understand the full magnitude of it. So the game is to muddy the waters and delay that broad acceptance for as long as possible. Even some of the spokespeople are re-used.

Simply put, this cannot be a political issue. Politics immediately descends into tribalism. People are collectively too stupid to make these decisions. But there's just no way around it because of how decisions are made in modern democracies.

Yeah sorry but anyone that believe my post deserved being attacked has got their heads way too deep into the climate change cult. You are essentially saying my factual post was attack worthy which shows how deep your commitment is to your cause as you are willing to attack anything that doesn't support it.

I didn't post Calgary's warming trend to pimp global warming, it was posted to show climate change and clearly Calgary has progressively gotten warmer over the last 40 years.

The brutal winter in the east has been blamed on a shift of the Jetstream but overall the planet was warmer this year than last and ...so on.

BTW, going back 10-15 years deGrasse,Nye and many others predicted brutal winters and bad winter storms in places where they never seemed to happen because of "global warming" if you have TED Talks you should be able to find the deGrasse one from 2005 where he predicts frequent brutal snow and ice storms in the southern states.
