Jan 20, 2012 Climate: Russell The Nottingham Trent University is having a lecture on climate change on 7 March. The speaker is Manoj Joshi of the National Centre for Atmospheric Science.
Climate change is one of the major environmental challenges facing humanity over the next century. Given its importance, the science of climate change encompasses many fields from the natural sciences to the social sciences. This talk will use the latest physical science to discuss three questions: is the world warming up; what are the causes; what will the impacts of climate change be?
Details here.

Bit too early for a definite but I hope to get to this event, dependent upon work commitments.
Manoj Joshi is not from the National Center for Atmospheric Research, which is in the US. He is from the National Centre for Atmospheric Science, which is in the UK. NCAS is geographically dispersed; Joshi is physically at the University of Reading.
[Thanks - fixed]
I think they should rephrase the initial premise from "Climate change is one of the major environmental challenges facing humanity over the next century" to "There is a wild conjecture that Climate change is one of the major environmental challenges facing humanity over the next century".
Brent,
That's just the obligatory show of piety.
Perhaps 'Climate change alarmism is one of the major challenges facing humanity..' would be more accurate.
Question #1 seems to be redundant when he asks question #3. That aside, I figure a fourth question needs to be added: What if we're wrong? And a fifth: How will we mitigate a cold climate?
It is well known that academics think excessively highly of their own work. "My work is important. Your work is interesting. His work is rubbish."
Towering self-regard expressed like "[My work is about] one of the major environmental challenges facing humanity over the next century" deserves loud sniggering.
Not even the heart surgeons I know have an ego like that.
Could be an interesting lecture

Hawey, man. Hoo aboot aall them nutters in Bishop Auckland and Berwick, like?
Bishop,
just for your information this lecture is taking place at Nottingham Trent University

Which is not the same as Nottingham University (University of Nottingham)

I see that Manoj Joshi is from UEA . I would not trust anything he or any other "scientist" from there without outside independent confirmation.
Have a heart for these newbie climate scientists. When they started this sexy study they weren't to know that four of the five premises upon which the subject is built are fundamentally wrong.
1. 'Back radiation' was a mistake by Arrhenius.
2. The assumption of 100% thermalisation of IR absorbed by GHGs was a mistake by Tyndall.
3. The assumption of 33 K present GHG warming was apparently a mistake by Hansen but no professional physicist should have made it.
4. The assumption that pollution causes significant increase of cloud albedo was a mistake by Sagan but he inherited some of it from van de Hulst. To match past temperatures, the models use double real cloud optical depth and net AIE 3-6 times higher than experiment. Because this physics is broken, the experimental data are also wrong. The bottom line is that no climate model can predict climate.
5. The assumption that part of the 'missing heat' is is from higher thermal diffusivity could be true [heat of mixing as recent Arctic melt water entered the N. Atlantic].
The jury is still out about when the subject descended into fraud. The publication by NASA in 2004 of fake physics [small droplets reflect more because of higher total surface area] was when it became overt as they desperately held the line; -0.7 W/m^2 median net AIE in AR4.
However, I suspect the fraud started in 1997 when the link between CO2 increase and the amplification of tsi change at the end of ice ages was broken. 'The Team' developed fake hock-sticks to exaggerate CO2 climate sensitivity but this was a hostage to fortune when the planet stopped warming.
Hansen's recent claim of ~50% increase of net AIE appears to be a desperate clutching of straws but he could still be right about the oceanic heat transport..
I think that Nottingham Trent used to be a Polytechnic, and therefore one can expect it to be rather leftist. Nottingham University is a Russel Group Unni, mind you it is AGW barmy since they are installing solar panels on many (if not mosts) of the roofs of their halls of residence.
