Post referendum analysis from Rodney Atkinson at Freenations.net

One of the most obnoxious features of the post Brexit climate is that the biggest liars and doom mongers in political history – the Remain campaigners – now accuse Leave Campaigners of lying! This has been picked up in continental attacks on Boris Johnson who, if anything, was rather kind and accommodating given the damage done to people, banks and businesses by the Euro corporatist elites. Now those liars are exposing their own lies:

THE IMF

Before the Brexit vote the IMF head, Christine Lagarde (whose appointment was avidly supported by George Osborne) said that the impact on the UK economy of a Brexit vote went from “pretty bad to very, very bad” and that there could be a recession.

Today the IMF says it has a “benign” view of the Brexit effect on the UK economy, there would be no recession and their revised forecast for UK growth is the same as their revised forecast for USA growth (-0.2% for 2016). Their forecast for UK growth in 2017 is 1.3%

Another interlude gives me space to update the novel statistics computed from published data. This is not comparable with the official methods, it’s better. Takes into account normal variation during a year; bends the data to near gaussian.

May was not particularly interesting, June was the 2nd dimmest for S and SE England since these records commenced 1929.

The following demonstrates that Metoffice Hadcrut4 is a restatement of the NOAA El Nino index. It’s based on the conjecture that not only do El Nino events have an immediate effect on world temperature but also the clustering of El Nino or La Nina events have a cumulative effect on the worlds temperature. Ian Wilson and Paul Vaughan have provide the frame work to show that El Nino events are governed by the interaction of the Sun and Moon coupled with the hemispherical asymmetry of the Earth’s surface properties. The climate variation is driven by the ratio in strength and frequency of El Nino to La Nina events.

Are we anywhere close to really understanding the strength of natural climate variation and how it works?

We can easily overlook that most temperature measurements are taken on land, but over 70% of the Earth’s surface is deep water.

Climate Research Unit, University of East Anglia

The Climatic Research Unit (CRU) was established in the School of Environmental Sciences (ENV) at the University of East Anglia (UEA) in Norwich in 1972.

The CRU has collected, collated and archived global climate data for over 40 years.

CRU temperature data

In 1987, the American Meteorological Society published a paper by Stanley Grotch of the Lawrence Livermore National Laboratory, University of California, that assessed the robustness of the CRU dataset for land and other datasets.

Monthly Weather Review, Volume 115 No. 7, July 1987, ISSN: 0027-0644; eISSN: 1520-0493

Abstract

Three data bases of gridded surface temperature anomalies were used to assess the sensitivity of the average estimated Northern Hemisphere (NH) temperature anomaly to: 1) extreme gridpoint values and 2) zonal band contributions. Over the last 100 year, removal of either the top or bottom 10% of the gridpoint anomalies in any year changes…

CO2Science summarises another study pointing to more ‘inconvenient’ data concerning the Medieval Warm Period.

In the introduction to their enlightening study, Miettinen et al. (2015) write that they “reconstructed August sea surface temperature (aSST) and April sea ice concentration (aSIC) at sub-decadal temporal resolution based on diatom assemblages found in sediment core MC99-2322 from the Kangerlussuaq Trough, SE Greenland shelf in order to investigate the variability of summer sea surface conditions along with possible forcing factors on the climatologically sensitive SE Greenland shelf during the last 1130 years.

Climate catastrophists should be careful what they wish for, according to this review featured by CO2 Science.

In a review of the human health effects of temperature, Seltenrich (2015) writes that “while isolated heat waves pose a major health risk and grab headlines when they occur, recent research has uncovered a more complex and perhaps unexpected relationship between temperature and public health,” which is, as he continues, that “on the whole, far more deaths occur in cold weather than in hot.”

It’s hard not to suspect a politicized element to the results of such a study due to the NASA/NOAA factor. They say Antarctic sea ice has increased ‘just slightly’ since the 1970s but some might put it stronger than that.

Why has the sea ice cover surrounding Antarctica been increasing slightly, in sharp contrast to the drastic loss of sea ice occurring in the Arctic Ocean? A new NASA-led study finds the geology of Antarctica and the Southern Ocean are responsible.

sensitivity-cartoonEnergy Balance Climate Sensitivity

The most important parameter in determining the economic impact of climate change is the sensitivity of the climate to greenhouse gas emissions. Climatologist Nicholas Lewis used an energy balance method to estimate the Equilibrium Climate Sensitivity (ECS) best estimate at 1.45 °C from a doubling of CO2 in the atmosphere with a likely range [17 – 83% confidence] of 1.2 to 1.8 °C. ECS is the global temperature change resulting from a doubling of CO2 after allowing the oceans to reach temperature equilibrium, which takes about 3000 years.

A more policy-relevant parameter is the Transient Climate Response (TCR) which is the global temperature change at the time of the CO2 doubling. A doubling of CO2 at the current growth rate of 0.55%/year would take 126 years. The analysis gives the TCR best estimate at 1.21 °C with a likely range [17 – 83%] of 1.05 to 1.45 °C.

The two periods used for the analysis were 1859-1882 and 1995-2011. They were chosen to give the longest early and late periods free of significant volcanic activity, which provide the largest change in forcing and hence the narrowest uncertainty ranges. The long time between these periods has the effect of averaging out the effect of short-term ocean oscillations such as the Atlantic Multi-decadal Oscillation (AMO) and the Pacific Decadal Oscillation (PDO), but it does not account for millennium scale ocean oscillations or indirect solar influences.

Andrea Leadsom MP

From the Daily mail:

In March Energy Minister Amber Fudd claimed energy bills would soar by £500 million a year if we left the EU, adding: ‘The thing about the gas market is you don’t know what shocks and what changes there can be to it.’

But in a remarkable rebuttal to her boss’s claims, Ms Leadsom said today that Brexit would threaten ‘absolutely none’ of the three ‘critical considerations’ at the forefront of Britain’s energy policy.

‘Leaving the EU will give us freedom to keep bills down, to meet our climate change targets in the cheapest way possible, and of course, keep the lights on,’ she said in a speech in central London.

Under the European Commission’s ‘Winter Package’ proposals all 28 EU member states would ‘take on legal responsibility for each other’s gas security’.

This would ensure that EU member states that face having their gas supplies cut – due to political disputes with countries such as Russia or contracts expiring, for example, – would see its gas supplies guaranteed by fellow member states.

Setting out the ‘real threat out continued membership of the EU will have on our energy security,’ Ms Leadsom said: ‘The European Commission’s ‘Winter Package’, contains a number of proposals which make painfully clear the direction of travel in EU energy policy.

‘Two of those suggestions pose a potential threat to our continued energy security.

Matt-RidleyCapX has a cogently argued piece from Matt Ridley on the reasons why Britains science endeavours would be benefited by #Brexit.

Britain – for its size – is probably the world’s leading scientific country. We have less than 1% of the world’s population, but 15% of the most highly cited scientific papers, and more Nobel prize winners than any other European country. We are world leaders in biotechnology and digital technology and our greatest potential collaborators and potential rivals in both fields are in Asia and America, not Europe.

So it is vital that we remain open to the world, not stuck in little Europe. A regional customs union protected by tariff walls and run from a central bureaucracy is a 1950s idea – an analogue project in a digital era, as Michael Gove puts it. In an age when container shipping has collapsed the cost of intercontinental trade; when the internet and budget airlines and Skype have made it as easy to collaborate with Asia and America and Africa as in Europe, regionalism makes less sense.

Climate scientist Ed Hawkins comments on the paper of which he is one of the co-authors. Others include Ben Santer and Michael Mann.

It has been claimed that the early-2000s global warming ‘slowdown’ or ‘hiatus’, characterized by a reduced rate of global surface warming, has been overstated, lacks sound scientific basis, or is unsupported by observations. The evidence presented in a new commentary in Nature Climate Change by Fyfe et al. contradicts these claims.

Earth and Planetary Science Letters Has an interesting paper in the works. A new proxy informs a model which finds bigger than expected swings in CO2 linked to smaller than expected temperature swings in the past five million years. This indicates that the Earth’s climate system is less sensitive to CO2 levels than previously thought. Maybe they should take more notice of Leaf Stomata calibrations than Antarctic ice cores?

CO2 over the past 5 million years: Continuous simulation and new δ11B-based proxy data

Abstract
During the past five million yrs, benthic δ18O records indicate a large range of climates, from warmer than today during the Pliocene Warm Period to considerably colder during glacials. Antarctic ice cores have revealed Pleistocene glacial–interglacial CO2 variability of 60–100 ppm, while sea level fluctuations of typically 125 m are documented by proxy data. However, in the pre-ice core period, CO2 and sea level proxy data are scarce and there is disagreement between different proxies and different records of the same proxy. This hampers comprehensive understanding of the long-term relations between CO2, sea level and climate.

Reblogged from Rt Hon David Davis MP’s website, this is a comprehensive look at the case for Brexit.

David Davis: Brexit – what would it look like? – 4 February 2016

It has been over 43 years since Britain joined the European Economic Community. For all that time there have been calls for Europe to reform. For Europe to be more democratic, more competitive, more functional. And for Britain to lead that reform.

The result? If anything Europe has become less democratic, less competitive and more dysfunctional. And Britain has become more side-lined.

The EU has been in decline for some time now. There is no change of course in sight. The risks involved in staying are clear for all to see – low growth, high unemployment, and waning influence.

In 1975 the EU was the bright future, a vision of a better world. Now it is a crumbling relic from a gloomy past. We must raise our eyes to the wider world.

My thanks to talkshop reader Jamal Munshi for alerting me to his paper on ozone and aerosols. It makes a strong case for viewing the ozone level above the Antarctic as a special case due to its unique geography, calling into question conclusions about human emissions drawn by scientists and acted on by the Montreal protocol. This is important as this agreement has been used as a template for ‘climate action’ subsequently.

ABSTRACT:

The overall structure of changes in total column ozone levels over a 50-year sample period from 1966 to 2015 and across a range of latitudes from -90o to +71o shows that the data from Antarctica prior to 1995 represent a peculiar outlier condition specific to that time and place and not an enduring global pattern. The finding is inconsistent with the RowlandMolina theory of chemical ozone depletion. 1 1.

INTRODUCTION

In 1971, renown environmentalist James Lovelock studied the unrestricted release of halogenated hydrocarbons (HHC) into the atmosphere from their use as aerosol dispensers, fumigants, pesticides, and refrigerants. He was concerned that (1) these chemicals were man-made and they did not otherwise occur in nature and that (2) they were chemically inert and that therefore their atmospheric release could cause irreversible accumulation. In a landmark 1973 paper by Lovelock, Maggs, and Wade he presented the discovery that air samples above the Atlantic ocean far from human habitation contained measurable quantities of HHC (Lovelock, Halogenated hydrocarbons in and over the Atlantic, 1973). It established for the first time that environmental issues could be framed on a planetary scale and it served as the first of three key events that eventually led to the Montreal Protocol and its worldwide ban on the production, sale, and atmospheric release of HHC (UNEP, 2000).
