I would like to welcome a number of posters to the George Orwell 1984 version of science. In this crazy world you can make any claim you like provided it meets you political goals. All data is rewritten or cherry picked to reflect the current political ideology.

The is no question that the globe has continued to warm over the last decade and a half anyone trying to claim anything else is simply trying to deceive or is seriously delusional.

For some 40 years we have known that human emissions of green house gases were sufficient to increase global surface temperatures. We have been able to show that surface temperatures have risen steadily since about 1970. We have been able to make a clear statistical link between rising temperatures and human GHG emissions since the early 1990s. We have even be able to measure the reduction in the amount of oxygen in the atmosphere caused by burning fossil fuels.

Now could somebody explain to me why it is necessary to deny the flaming obvious. I refuse to believe that the majority of people are so dumb, that they are unable to understand that pouring gases into the atmosphere that restrict the rate at which the earth cools is not going to have serious consequences.

As regards the idea of geoengineering, this should only be attempted as a last resort if the human race is really so stupid, that it would rather wreck the planet, than pay just a little more for its energy. According to the IPCC the action required to gives a reasonable chance of avoiding a temperature increase of no more than 2 Deg C would set us back by about one year, by 2100.

'cohenite says Sherwood's drivel is critiqued by Alec Rawls:'

And you want to listen to an economist who could not predict the GFC and no expertise in climate science.
It is like asking a dentist about your stomach ache, I will pull a tooth out and your stomach ache will disappear.

Again we are seeing denialists making statements that have no substance and to claim to know about science when they have no education!!

Or refer to debunked unreliable sources like WUWT (WeUseWishfulThinking).

Out of nearly 14000 pear reviewed papers on climate science supporting AGW only 24 were in denial and they have been debunked and no one cites them except them selves.

So where is your evidence to show that AGW is not occurring?

PeterA, great analysis! One reference to the fallacy of consensus wrapped in another of authority. Well done! And as well you attack the man, not what he says which is incontrovertible proof that Sherwood is ignoring evidence.

The denialist here is you mate.

Sherwood is an alarmist of the lowest order; his papers which I have linked to show that; Rawls' evidence shows that. This paper by Sherwood is drivel and contradicted by basic physical principles and Paleoclimate history:

http://www.pnas.org/content/107/21/9552

The basic physical principle he ignores is enthalpy; that is, evaporated water cannot both heat and be evaporated; the energy can only be used once.

He also ignores the phase changes of water and the negative feedback of those water states.

The paleoclimatic evidence he ignores is the fact the never in the history of the Earth have temperatures been 12C above current levels, even when CO2 levels were 20 times today's levels:

In fact the highest ever temperature on Earth was 250 million years ago when it was 9C above current levels; at that time CO2 levels were no where near their highest point:

I don't know where you get your 24 papers disproving AGW compared to 14000 papers supporting it and don't care; you've got nothing to say, just like all the AGW nutters.

You only have to google chemtrails to quickly learn that they are experimenting with geo-engineering.This also includes Russia and China.

They are pouring millions of tonnes of nano sized particles of aluminium and barium into the atmosphere to see if they can reflect the energy from the Sun.In parts of the USA this is detroying soils and people' health much like the coal seam gas industry.

Some say that this is being used in conjuction with the the US Military HAARP program in which a billion watts of power can act a catalyst to change local weather.This HAARP project is part of Ronald Reagan's Star Wars Program.

If the Russians in 1961 could produce a 100 megaton bomb which was scaled down by half for safety reasons,what new weapons have they now developed? The Russian Tsar Bomb of 50 mega tonnes gave 3rd degree burns in a 100 km radious and broke windows 900 km away.

The lunatics are incharge of the Nukes but our Govts want to disarm the people?

Warmair. You state "
"The is no question that the globe has continued to warm over the last decade and a half anyone trying to claim anything else is simply trying to deceive or is seriously delusional"

Would you care to give us the actual temperature figure there? Perhaps you could quote the figure from NOAA. Perhaps from IPCC AR5? It would support your contention wonderfully.

"We have been able to make a clear statistical link between rising temperatures and human GHG emissions since the early 1990s"

Again, could you perhaps provide some data supporting the above with particular reference to the correlation between anthropogenic Co2 emissions and temperature over the past decade and a half?

Regards.

At least I do not deny science it just that deniers such as cohenite never provide evidence other than cherry picked information that has been debunked or provide links to sites that have no science creditability.

cohenite may not like to know (and shut his eyes to the real world) but other might so the web site on peer reviewed papers from 14000 climate scientists is at.

Okay, NOAA’s State of the Climate Report for November isn’t the Mayan meteorological forecast. And the Apocalypse isn’t quite “now.” But this part of the NOAA report is kind of ominous:

Including this November, the 10 warmest Novembers have occurred in the past 12 years. The 10 coolest Novembers on record all occurred prior to 1920. November 2012 also marks the 36th consecutive November and 333rd consecutive month with global temperature higher than the long-term average. The last month with a below average temperature was February 1985, nearly 28 years ago.

And you are still denying that the world is warming.

And no denilist has given any reason why it is doing so other than saying it is not CO2
