Dan Miller's presentation focuses on why the UN IPCC (Intergovernmental Panel on Climate Change) reports are actually best case scenarios. For example, IPCC climate models do not include the effect of melting permafrost releasing greenhouse gases, even though the permafrost is melting now and it holds more greenhouse gases than all that mankind has ever released.
Another example is that IPCC predictions of sea level rise only take into account thermal expansion of the oceans and melting of glaciers; the largest factor, disintegration of glaciers, was not included because it is hard to model. The result is that sea level rise will likely be substantially higher this century than the IPCC predicts.
Miller discusses several other potential catastrophes that are not included in IPCC predictions and also discusses tipping points that could put climate change solutions out of our reach in years or decades, the psychology of climate change, and why it is difficult for people to respond to the threat posed by a warming earth.
His talk concludes with a discussion of ways to address climate change and the risks and opportunities that companies face due to the climate crisis.

Mr. Miller retired from the Board of Directors of TCSI in June of 1997. TCSI is a leading provider of integrated software products and services for the global telecommunications industry.
Prior to TCSI, Mr. Miller was a systems engineer at Hughes Aircraft's Space and Communications Group where he was responsible for designing communications payloads for commercial communications satellites.
Increase in the global average surface temperature resulting from enhancement of the greenhouse effect, primarily by air pollution. In 2007 the UN Intergovernmental Panel on Climate Change forecasted that by 2100 global average surface temperatures would increase 3.27.2 °F (1.84.0 °C), depending on a range of scenarios for greenhouse gas emissions, and stated that it was now 90 percent certain that most of the warming observed over the previous half century could be attributed to greenhouse gas emissions produced by human activities (i.e., industrial processes and transportation). Many scientists predict that such an increase in temperature would cause polar ice caps and mountain glaciers to melt rapidly, significantly raising the levels of coastal waters, and would produce new patterns and extremes of drought and rainfall, seriously disrupting food production in certain regions. Other scientists maintain that such predictions are overstated. The 1992 Earth Summit and the 1997 Kyoto Protocol to the United Nations Framework Convention on Climate Change attempted to address the issue of global warming, but in both cases the efforts were hindered by conflicting national economic agendas and disputes between developed and developing nations over the cost and consequences of reducing emissions of greenhouse gases.
Because this is a bogus religion and if the so called scientists were to tell the truth, they would not get millions upon millions of dollars in project funding.
All those millionaire scientists are going to be pissed that you said that. Boy, I wish I'd studied physics, I'd be stinking rich now.
What a sick lot of scumbags?
Your business is population control.
Squeeze the naive and innocent out of life to satisfy your perverted appetite.
Control freaks leading by deception.
You're all going to end up in jail for your fraudulent science and your crimes against humanity.
I have not heard of using vortexes for geo-engineering so I can't comment on them. I don't believe that was mentioned in the Royal Society's recent report on geo-engineering.
Energy requirements are usually not an overriding concern for geo-engineering. "Smoke in the atmosphere" doesn't use a lot of energy relative to its effect on the atmosphere. Air capture could use coal power and it would only lose around 20% of its effectiveness, and biochar actually generates energy as a bi-product!
I think peak-oil is real and recent reports place it around 2014! It will generally have a positive effect on climate change since a high price for oil will made alternatives such as renewables (and electric cars) more cost competitive. It won't do good thinks for the economy, though. So, as someone else said, we should leave oil before it leaves us.
Saul Griffith's talk (also on FORA.tv) does a good job of explaining how much dirty energy can "spend" and how we better use it to create the new low-carbon economy.
First, in your discussion of geo-engineering I was surprised that you didn't mention vortex research. I heard about the concept in Ode Magazine. A guy by the name of Jay Harman talks about using the natural properties of vortexes (the natural way water and air move) to bring the atmosphere back into balance. It would be interesting if you could weigh in on this (even though you are probably not an expert on this type of science).
Second, I wanted to point out that this presentation, in keeping with other similar types of climate-change-only talks never brought up the concept of peak oil/energy decline or the concept of net energy or even net environmental impact (particularly when you talk about geo-engineering ideas that obviously have drastic energy requirements, like building giant carbon air filters). It seems to me that this issue is completely avoided in such talks. Even Al Gore doesn't talk about it.
I want to know, do you think that Peak Oil (and the reason Peak Oil versus coal or gas or other fossil fuel source is because petroleum is the fuel source with the most amount of energy per unit of volume and in which every facet of our modern lives currently depends on, either directly or indirectly) is a legitimate concern?
Most of the proposed geo-engineering solutions would "work". The question is what are the side effects? Some, like reforestation and biochar probably don't have very bad side effects besides cost.
The "side effect" of doing nothing may be collapse of civilization or worse, so that may not be a good choice.
Eyjafjallajokull did this for us. Man screws up -- nature retaliates ferociously. We have not been able to take care of the earth....what makes us think geo engineering is going to work. Just another experiment, but we are living inside that test tube!
Wonder who the idiot mouthing off at the end is. It's sad because my wife and I are wanting to start a family but we aren't sure that it would be fair to bring a child into a world like this.
Warm air holds more moisture than cool air, so their is more humidity even without sea level rise (and this is why it snows more in warm winters than in cold winters!). Water vapor is also a greenhouse gas so this ends up warming the earth even more. Now, your point is that more water vapor would lead to more clouds and this will reflect light, leading to cooling. While everyone hoped this would be a dominant effect, it hasn't turned out to be a factor that can counter the overall warming. Cloud variability is certainly already included in climate models.
The sun has an 11 year sunspot cycle and it's output varies a little bit over that cycle. It's effect is about +/-10% of the warming we have seen so far. 2010 is on track to be the warmest year since temperatures were measured even though the sun is currently near the bottom of its cycle (i.e., solar energy reaching the earth is lower than normal).
Here is my provocative message:
I hear all this global warming bla bla - but in all honesty even this presenter has a big flaw in his presentation.
Ice is melting - sea level rises - dark water absorbs sun - ice reflects sun =====> Global warming and we are cooked !
Now think simple. ice melts - flows into the sea - sea level rises - more water surface on earth and warmer - (?) - more water evaporates - more humidity -===> more clouds (?) - clouds are white and very effectively reflect sun light.
..another one is that the solar wind and sun energy is fluctiating and has an incredible impact on our planet - again this is not even mentioned.
2 flaws, right ?
So why are those global warming experts missing on a simple physical effect ??
This at least for me diminishes all of those people's credibility - one day is somebody can pull all those depencies together and come up with a logic story i am buying into it - until then i suggest to forget this half-science.
Having said all this - there is NO question that man made global warming is not doing ANY good - so with or without solid expert knowledge - our world societies should develop towards renewable energies and sustainable economies. I doubt that we need the false information from Global warming enthusiasts to achieve this goal.
