Engineering the climate: is science fiction becoming reality? : Comments

By Kerryn Brent and Jeffrey McGee, published 19/12/2012

It will be difficult for countries to resist experiments in geoengineering as it has the allure of being a relatively inexpensive and quick response to climate change impacts.

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.
______________________________________________________________

I would refer you to page 69 figure one of ARF5 (First Order Draft Technical Summary IPCC WGI Fifth Assessment Report). This clearly shows from multiple lines of evidence and sources that surface temperatures are rising and have continued to do so over the last decade and half. The diagrams for temperature anomalies are on page 77 which include observations from HadCRUT4, GISTEMP, and 5 NOAA NCDC, JMA, temperature sets.

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

Prompete says
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?

From here we have a diagram illustrating the the relationship between temperature and CO2 emissions over the last 130 years

More specifically in AR4 they assign a probability of 90% that rising Greenhouse gases are the dominant factor in the current warming.

PeterA, you’re a bit of a caricature with your ‘denialist’ insults and regurgitation of untruths like hottest years and summers and ½ past 10s on a Friday night ever gibberish.

For a complete explanation of why AGW is a failed theory see the papers listed at Jo’s:

http://joannenova.com.au/2012/10/man-made-global-warming-disproved/

This link shows the basic flaws in AGW science and lists dozens of papers which show these flaws.

Some of these papers are described in more detail here:

http://theclimatescepticsparty.blogspot.com.au/2012/10/has-man-made-global-warming-been.html

And here:

http://theclimatescepticsparty.blogspot.com.au/2012/10/has-global-warming-been-disproved-part-2.html

The 5th paper discussed shows the lie of the claims that the last years have been the hottest.

Any one of these papers shows the lie that AGW is; and there is ample evidence that AGW ‘scientists’ are prepared to lie, manipulate and distort to sell their product; for instance the emails.

The supporters of AGW are naive, arrogant and wrong; and that explains their anger when the lie of their belief is revealed. Too bad PeterA, you’ve been a sucker and supported a scam and a lie which has cost the world $billions and stymied real research into the environment and other worthwhile projects. I hope you’re proud.

One good thing though, the AGW lie has revealed the greens for the misanthropes they are.

You actually believe this stuff don't you warmair?

You poor sod.

Warmair, you’re an AGW sucker too; the AR5 clearly shows that the IPCC’s temperature projections have been greatly exaggerated as these comparisons between the predictions in 1990 and the observed trends show:

As for temperature increase from 1998 both the satellite and ground based temperatures show falls:

http://www.woodfortrees.org/plot/hadcrut3vgl/from:1998/mean:12/plot/hadcrut3vgl/from:1998/trend/plot/rss/from:1998/mean:12/plot/rss/from:1998/trend

The importance of 1998 is that it is the highest temperature in the modern satellite era, and if AGW were real it would be exceeded; it hasn’t been and trends have been down since 1998 consistent with a –ve PDO phase change around that time.

In other words it’s all natural.

Cherries are now in season and very good they are too, but is it really necessary to use them to make a total erroneous point. Every body should know by now that 1998 was one of the strongest El Nino events of the last century. The El Nino of 1998 spiked temperatures but as much as 0.8 of Deg C during the peek period, whereas GHGs are increasing temperatures at rate of about 0.018 C per Year. Nevertheless 2005 and 2010 were warmer using data taken from the WMO average of HADCRUT, NASA and NOAA temperature datasets .

Gibberish; only GISS shows 2010 higher than 1998:

GISS is an outlier, adjusted to show AGW:

Just another AGW lie
