Jules is writing up an in-depth report about the Tobacco Institute, with some interesting new views on the topic, check it out!

From the reviews:

"Excellent work" - John Mashey

Here are some questions:

I heard that our current rate of emissions is ten times that of past events, but this one seems to have been much faster?

And, according to Wikipedia, there is »no evidence of any increased extinction rate among the terrestrial biota«. Would that mean that at least at the time they were more robust than we would have thought?

Bonus point for realizing there's a future beyond 2100.

Greg Laden on weather whiplash.

Should be obvious, but obviously isn't obvious enough for most people.

»Farmers have to put their crops in late because of a long period of cool and wet conditions. Then the weather clears and everything is nice and dry, so the farmers plant later than ideal, but at least they get to plant. But then the nice and dry conditions are like the proverbial TV in-laws and never seem to want to leave, and good planting conditions turn into a worrying period of not enough rain and that turns into a moderate drought, and that turns into a severe drought. Then, just as you are about to harvest the half dead corn and maybe use it for halloween decorations because it is not good for anything else, the weather whiplashes on you again and your half dead crops are mowed down by a series of hail storms. This is not good for farmers.«

Nice visualization.
As our planet warms, sea level is on the rise.  There are 3 main reasons why warming causes sea level to rise.  First, as the oceans warm up, the water particles move further apart - which creates expansion.  The second problem comes from warmer air temperatures, which is increasing the rate of polar cap and glacier melting, and decreasing the average snowfall (so more water is being released then is 'locked in' by ice.  Finally, warmer weather is also causing the ice sheets of Greenland and West Antarctica to melt much more rapidly then they would do under cooler temperatures.  We are also seeing an increase in ice shelves breaking off as the ice heats up and weakens.  

But predicting just how much average sea level will rise by any particular date isn't an easy task - let alone predicting how different parts of the globe will be impacted.  The latest IPCC report is coming out shortly.  The first part - 'The Physical Science Basis' is due out next week, and the global sea level rise figures presented therein will be better than previous reports.  There are still a number of knowledge gaps though, as well as limitations to the models we can use to predict how much and how fast sea level will rise by.  In this open access article in the journal 'Nature', climate scientists discuss some of the uncertainty they are still trying to reduce
