The Truth Behind Christian Aid’s Campaign

Now It’s OK To Lie About Climate Change – Yale Project

Studies recently show that the global warming trend is in a bit of a slowdown. Does that mean we may be nearing the end of the heating period? Well, experts say that the slowdown may be quite misleading.
The study authors describe, “The recent slowdown in global warming has brought into question the reliability of climate model projections of future temperature change and has led to a vigorous debate over whether this slowdown is the result of naturally occurring, internal variability or forcing external to Earth’s climate system.”
Study author Anthony Leiserowitz goes on to describe “It’s fair to say that the vast majority of the public is completely unaware of the word ‘hiatus,’ or the word ‘pause,’ or any of the arguments that have been going on for a few years now between the scientific community and the deniers. The vast majority of, well, at least Americans, rarely hear about climate change in the media.”
Indeed, many people were a bit surprised to find that global warming was not, in fact, a myth; and more importantly, that the state of global warming was nearing critical mass and we are now in a place where we must make drastic changes or face equally dire consequences.
The Yale Project on Climate Change Communication lead researcher continues, “There have been a number of studies that have shown that some people will change their views of climate change based on extreme weather. It’s not enough to simply experience a heat wave — it then needs to be contextualized. It needs to be interpreted by thought leaders and trusted people in a community and by the media and scientists saying, ‘This is an indication of global warming.”
I’m not sure what Leiserowitz has been smoking if he really thinks the vast majority of, well, at least Americans, rarely hear about climate change in the media.
But his final paragraph gives the game away.
There have been a number of studies that have shown that some people will change their views of climate change based on extreme weather. It’s not enough to simply experience a heat wave — it then needs to be contextualized. It needs to be interpreted by thought leaders and trusted people in a community and by the media and scientists saying, ‘This is an indication of global warming”
So, apparently, it is now OK for scientists and other “trusted people” to make claims they know are not true, and use any extreme weather event to support the theory.
Has science really sunk so low?
Polar Vortex Common In The 19thC
By Paul Homewood
I came across a chapter in Hubert Lamb’s “Climate, History and the Modern World”, which has more than a bit of topical relevance.
We are all well aware of the extremely cold winters in the eastern half of the States, both this year and last. This has coincided with warm winters in the west, the sort of extreme weather which warmists would like to blame on “climate change”.
Well it turns out that they had the same weather patterns in the 1850’s and 60’s, and the reason was just the same – a meridional jet stream.
HH Lamb – Page 253
Lamb believed that this meridionality was actually more common during the Little Ice Age, and there is plenty of evidence of the same phenomenon during the cooling period of the 1960’s and 70’s.
Is the latest incarnation of this just weather, or an indication of a return to a colder era? Either way, it won’t stop junk scientists blaming it on “global warming”.
Christian Aid Saving The World From Global Warming!

It seems Christian Aid are banging their global warming drum again!
Maybe they could tell us where all these communities are around the world, who are suffering from the effects of climate change?
Their website does actually offer a couple of case studies.
Mikey Discovers Ocean Cycles!
By Paul Homewood
Climate “scientist”, Michael Mann, has discovered that the 17 year pause in global warming is due to “internal variability”, particularly ocean cycles. In a paper written with a Byron Somebody, and someone called Sonya, he finds:
That internal variability is found in the natural cycles of temperature change that occur over years or even decades in the oceans, like El Niño and La Niña. There are others, like the “Atlantic multidecadal oscillation” and the “Pacific decadal oscillation”…
There is an oceanic tug-of-war between the two systems. Sometimes the ocean cycles worked together to suck heat or burp it skyward—sometimes their push-pull led to a draw.
Welcome to the party, Mikey! Some of us have been explaining about this for years.
There is just one slight snag with your explanation. We have been in the warm phase of the AMO since around 1997, and this is actually helping to keep global temperatures up.
As can be seen from the ESRL graph below, when the AMO and PDO moved in concert from cold to warm, first in the 1920’s and 30’s, and later in the 1980’s and 90’s, global temperatures went up.
And when they both turned cold together between the 1940’s and 70’s, temperatures fell.
Currently the cold PDO and warm AMO are helping to offset each other. With the negative PDO likely to last another two decades, and the AMO likely to head south (not literally!) soon, we can expect another 30 years of pause, if not outright cooling.

Myths About Biomass
By Paul Homewood
It is often claimed that producing electricity from biomass is carbon neutral, and that the CO2 emitted into the atmosphere is simply taken back out when forests are replanted.
Unfortunately, things are not as simple as this.
Last April, a number of environmental scientists from the US wrote to Ed Davey outlining their concerns on the matter.
The Met Office & The Pause
By Paul Homewood

The Met Office have had another attempt at explaining the global temperature hiatus.
Using, you’ve guessed it, “models”, they conclude:
A new study, led by Met Office climate scientist Chris Roberts and colleagues, looks at this issue by using a huge archive of climate model simulations collected from a number of international research centres. These are used to study whether internal variability has the potential to offset the expected global surface warming rate of 0.2 °C per decade associated with human influences.
This archive of 15,000 years of simulated climate represents a ‘laboratory’ in which to study the characteristics of the internal climate variability in the absence of changes in external forcing. These would be impossible to disentangle from the relatively short 150 years of the global observational record, where a number of external forcings come into play.
The researchers found that 20-year periods of global cooling in excess of 0.2 °C per decade can occur, as a result of internal variability alone, about once every hundred years. Once cooling has been established for 15 years, there is also a high chance (up to one-in-four) that this will persist for a further five years.
One would have thought they might have put rather less emphasis on their models, given their abysmal failure so far.

Others have covered Roger Pielke Jnr’s run in with US Representative Raúl Grijalva (D-AZ) who is the ranking member of the House of Representatives Committee on Environment and Natural Resources. Anyone who has not seen it, Roger has it on his blog here.
But just to bring home Stalinist nature of the “investigation”, I copy below the actual letter sent by Grijalva to the president of Pielke’s university.
