Piers Corbyn challenges Top Meteorology professor to provide observational evidence of so-called man-made ‘climate change’.

Piers at the Electric Universe conference 2014

On Mon 16th May at the annual Imperial College Lighthill Lecture* – this year by Professor Sir Brian Hoskins on ‘Predicting Weather and Climate’ – WeatherAction astrophysicist Piers Corbyn, First class Physics graduate from Imperial College, challenged Sir Brian to produce observational evidence of CO2 driving changes in Climate     * http://www.imperial.ac.uk/fluids-cdt/about/lighthill-lectures/

In the discussion section of the event Piers thanked Sir Brian for his superb presentation on meteorology concepts and processes and said that however he had difficulty with his comments on Carbon dioxide and climate. Piers said

“The problem you have is that there is no observational evidence that world temperatures follow CO2 levels but the relationship is the other way. The trace gas CO2 follows temperatures with delays of some centuries because the relative partition between CO2 in the air and in the sea – which holds 50 times more CO2 than the atmosphere – is controlled by Sea (surface) temperatures (under Henry’s Law) and I challenge you to provide evidence of your claims”

Sir Brian said there was evidence in the UN IPCC reports. 

Piers said “No, there is no evidence in those reports only opinion. We must rely on evidence not opinion”. Sir Brian said he agreed evidence not opinion was required. Piers said Yes we need to see a graph of observational evidence please send evidence to piers@WeatherAction.com ”

Afterwards Piers gave his business card with email to Sir Brian.

Further Comment from Piers: We will keep WeatherAction site updated on any responses. Sir Brian’s CO2 and Climate claims did not follow in any way from the main part of his presentation on world weather description parameters and meteorological concepts and processes. 

His claims that Man’s CO2 lasts thousands of years and that this is causing Ocean acidification are factually false (but we didnt have time to discuss these). For a start IF Man’s CO2 lasts thousands of years in the atmosphere it cannot also be in the sea causing so-called ‘acidification’. The fact is that because the sea holds 50 times more CO2 than the all even if all atmpsheric CO2 went into the sea – let alone man’s 4% contribution to it – which anyway it cannot because of Henry’s partition Law, it could potentially have only a trivial effect which is further suppressed by the ‘buffer solution’ nature of the sea. 

There is a dynamic balance between CO2 in the sea and air and on average half any atmosperic@ CO2 will enter the sea in a few years and CO2 is similarly releaased from the sea at close to the same rate.

Piers Corbyn – “World weather is now developing faster into grim new era”

Ned Nikolov: In Science, New Messages Mean More than the Messengers’ Names

“the effect of CO2 on climate is only visible in model outputs, but has never been observed or shown in reality.”

Stating this simple truth has caused those with closed minds to reach for their blunderbusses and crayons, so they can see off the truth which threatens their cosy little empire of lies, which is why Gavin Schmidt’s response starts with an ad hominem;

“climate contrarians”

And why there is a bitter irony that his teams’ despicable data torture to make CO2 match temperature is by far the worst “curve fitting” exercise that some would call criminal:

Research Paper Withdrawal by the Journal Advances in Space Research  

peer-reviewQ1: As succinctly as possible, could you tell me why you chose to publish this work under a pseudonym?

A1: We adopted pseudonyms as a measure of last resort as we could not get an unbiased and fair review from scientific journals under our real names. This is explained in more details in the attached letter we sent to the chief editor of the Journal Advances in Space Research (JASR) on Sep. 17, 2015. In brief, our real names became known to the climate-science blogosphere in 2012 when a poster, which we presented at an International Climate Conference in Denver in 2011, became available online and caused broad and intense discussions. When we later tried…

September 2016 Heatwave


By Paul Homewood



The Met Office have now published a bulletin on the brief heatwave last week:

A brief heatwave from 12 to 15 September brought exceptionally high temperatures to south-east England, accompanied by some torrential downpours causing flash flooding.

On 13 September, Gravesend (Kent) recorded 34.4 °C, the UK’s highest temperature of the year and the highest September temperature since 1911; this value being around 14 °C above the long-term average. Daily minimum temperatures for 14 September were also exceptionally high, at a few locations exceeding 20 °C.

The heat was associated with a southerly flow of air from France and Spain, with the humidity leading to thunderstorms bringing intense downpours and causing flash-flooding. Several locations recorded hourly totals exceeding 30mm.

Can’t See Forests for the Theory

When CO2 and the temperature were high the earth thrived…something the ‘greens’ ‘deny’

Science Matters

Warming alarmists see no good coming out of rising CO2 and the current climate optimum, and their warnings extend to forests as well. So in love with their theory of global warming, they cannot see the forests as they are, and as documented in numerous research studies.

Claim: Forest growth is diminished by higher CO2 and warmer summers.
Fact: CO2 increases have improved forest health.

Claim: Forest areas will be hard-hit by future droughts.
Fact: No trend in droughts is discernible.

Claim: Warmer temperatures increase damage from pests and pathogens.
Fact: Enhanced CO2 is making forests more resilient to diseases and infestations.

Claim: Old growth forests will not sequester CO2 as young forests do.
Fact: Rising CO2 has given new life even to aging forests.

Study: Tropical Hotspot ‘Fingerprint’ Of Global Warming Doesn’t Exist In The Real World Data

Watts Up With That?

One of the main lines of evidence used by the Obama administration to justify its global warming regulations doesn’t exist in the real world, according to a new report by climate researchers.

Guest essay by Michael Bastasch, reprinted with permission

Researchers analyzed temperature observations from satellites, weather balloons, weather stations and buoys and found the so-called “tropical hotspot” relied upon by the EPA to declare carbon dioxide a pollutant “simply does not exist in the real world.”

They found that once El Ninos are taken into account, “there is no ‘record setting’ warming to be concerned about.”

“These analysis results would appear to leave very, very little doubt but that EPA’s claim of a Tropical Hot Spot (THS), caused by rising atmospheric CO2 levels, simply does not exist in the real world,” reads the report…

New USGS study shows heat retaining concrete and asphalt have encroached upon US Climate Stations

“In this study, they have observed over 32% of the USHCN stations exhibited an increase in impervious surface area of ⩾20% between 2001 and 2011. When the 1000 m radius associated with each station was examined, over 52% (over 600) of the stations exhibited an increase in ISA of ⩾20% within at least 1% of the grid cells within that radius.”

Watts Up With That?

A new study from USGS by Keven Gallo and George Xian verifies what we’ve already learned and published on via the Surface Stations project; that concrete and asphalt (aka impervious surfaces) have increased near weather stations that are used to monitor climate. In this case, it is the much studied USHCN, that climate network I presented a poster on at AGU 2015. Details here.

What is most important about this paper is that it quantifies the percentage of stations that have had increased amounts of impervious surface area getting closer to the stations. As I have long since maintained, such things act as heat sinks, which increase the night-time temperature when they released the stored energy from the sun that was absorbed during the day as infrared, warming the air near the thermometer, and thus biasing the minimum temperature upwards.

More Detail On Gravesend’s “Highest Temperature”

One wonders in years to come of we might not see Liu comments like this, especially considering Tim’s comments) regarding the Faversham and Gravesend sites (summer 1868):

. Although not accepted (because of problems of comparison between Glaisher and Stevenson screens), the maximum temperature recorded on the 22nd July, 1868 at Tonbridge, Kent is still remarkable: 100.6 degF/(converted=38.1degC) [ It is now thought that this value, when compared with the ‘standard’ Stevenson screen, is about 1.5C or 2C too high.]



By Paul Homewood



I have been waiting for some information from the Met Office about the “hottest day since 1911”, which has finally come.

I will do a full analysis tomorrow hopefully, but this bit is important and needs a post of its own.

As you will probably be aware, we keep on seeing apparent “record temperatures” either at Gravesend in Kent, or Faversham, just 24 miles away.

The UK record temperature of 38.5C was set in Faversham in August 2003. It was Faversham again which set the highest temperature last month. Now it is the turn of Gravesend to record the “highest” temperature since 1911. (Unless they get another late reading from Faversham!)

Legitimate concerns about the siting of thermometers at Faversham have been raised, and also the local environs at Gravesend. I raised this issue a couple of weeks ago here.

I don’t want to revisit…
