A high powered and independent scientific inquiry has been set up by the GWPF to look into the question of temperatures adjustments.

Booker has news on this, as well as the latest claims of hottest years, which are not backed up by the more accurate and comprehensive satellite data.

 

Last month, we are told, the world enjoyed “its hottest March since records began in 1880”. This year, according to “US government scientists”, already bids to outrank 2014 as “the hottest ever”. The figures from the US National Oceanic and Atmospheric Administration (NOAA) were based, like all the other three official surface temperature records on which the world’s scientists and politicians rely, on data compiled from a network of weather stations by NOAA’s Global Historical Climate Network (GHCN).

But here there is a puzzle. These temperature records are not the only ones with official status. The other two, Remote Sensing Systems (RSS) and the University of Alabama (UAH), are based on a quite different method of measuring temperature data, by satellites. And these, as they have increasingly done in recent years, give a strikingly different picture. Neither shows last month as anything like the hottest March on record, any more than they showed 2014 as “the hottest year ever”.

What The IPCC Said About Ocean Temperatures In 1990

April 25, 2015
tags: ,

By Paul Homewood 

 

It’s amazing what you find from the 1990 IPCC Report when you look. These were the days, of course, before the IPCC became fully politicised.

In their section on sea temperatures, they discuss the big cooling of the Atlantic in the 1960’s and 70’s.

They continue:

What they are talking about is the immense heat storing capacity of the oceans, and how changes in circulation patterns can have a significant effect on climate, maybe decades or even centuries later.

The ability of CO2 to affect ocean temperatures is tiny in comparison.

Unfortunately, many scientists today find it easier, and more profitable, to blame all changes on CO2 and ignore all of the natural processes taking place.

Oceans Were Warmer In MWP

By Paul Homewood

  

While we’re on the topic of sea surface temperatures, let’s take a look at this paper from 2013, that I don’t recall the BBC or Guardian reporting!

ABSTRACT

Observed increases in ocean heat content (OHC) and temperature are robust indicators of global warming during the past several decades. We used high-resolution proxy records from sediment cores to extend these observations in the Pacific 10,000 years beyond the instrumental record. We show that water masses linked to North Pacific and Antarctic intermediate waters were warmer by 2.1 ± 0.4°C and 1.5 ± 0.4°C, respectively, during the middle Holocene Thermal Maximum than over the past century. Both water masses were ~0.9°C warmer during the Medieval Warm period than during the Little Ice Age and ~0.65° warmer than in recent decades. Although documented changes in global surface temperatures during the Holocene and Common era are relatively small, the concomitant changes in OHC are large.

What The IPCC Said About Glaciers In 1990

When we talk about glaciers retreating, it is worth recalling what the first IPCC Report in 1990 had to say about the matter:

In other words, glaciers began receding in the second half of the 19thC, and the fastest rate of retreat was 1920-60, before CO2 emissions could have had any significant impact.

The IPCC also added the following chart showing how, on a range of glaciers, rapid retreat began in the 19thC.

They also added:

How CRUTEM4 Cranked Up The Warming

April 22, 2015

By Paul Homewood   

 

The Met Office’s Hadley Center are responsible for compiling the HADCRUT global temperature datasets, in collaboration with the Climatic Research Unit at the University of East Anglia.

In 2012, they brought out the new HADCRUT4 version, which had the effect of slightly increasing the warming trend, particularly in recent years. As part of the switch from HADCRUT3 to HADCRUT4, they also introduced a new land only temperature series, CRUTEM4.

Woodfortrees noticed at the time how much this had changed since the CRUTEM3 version. And, unsurprisingly, it had the effect of increasing the warming trend.

According to Woodfortrees, CRUTEM4 seems to have a markedly higher recent trend (2.8°C/century) than CRUTEM3 (2.2°C/century).

In other words, nearly a quarter of the claimed land warming has resulted from the change in dataset.

E Calvin Beisner Demolishes More Climate Scare Stories In Africa

A couple of weeks ago, I ran a post on an article written by E Calvin Beisner, which demolished claims in the Christian Post that climate change was bringing disaster to Kenya.

For those who have not read it, it is here.

 

Beisner had written a similar piece in 2013 about inaccurate claims made about Malawai, again by a couple of evangelical environmentalists. It was actually published by WUWT, but it is worth rereading now as these claims by Christian outfits are clearly part of a pattern.

 

Guest essay by E. Calvin Beisner

In late May two evangelical environmentalists, recently returned from visiting Malawi, published articles in which they said poor Malawians are suffering from reduced rainfall caused by manmade global warming.

Jonathan Merritt wrote for Religion News Service, “In America, climate change is a matter of debate, but in places like Malawi, it’s a matter of life and death.” Judd Birdsall wrote for Huffington Post, “In Fombe village, Malawi, climate change is not a matter of political or scientific debate. It’s a matter of survival.”

The implication was clear: To help the poor in Malawi (and other developing nations), we must fight global warming.

If either author had dug deeper, he might have concluded differently.

Flamanville nuclear reactor fault a fresh blow for Hinkley Point C – Power Engineering International

April 21, 2015

There seems to be more trouble brewing for the new nuclear power plant planned for Hinkley Point, with news that a very serious fault has been found in the pressure vessel at the Flamanville plant in France.
Flamanville uses the same reactor as the one proposed for Hinkley.

Hinkley is already running late, and there are still challenges to overcome with Austria objecting to the subsidies agreed. There are now fears the Chinese may pull their funding out.

With the rest of the UK coal plants due to shut in the next few years, the challenge of keeping the lights on in ten years time is becoming ever more difficult.

Three years ago, Britain’s last major aluminium smelter, Lynemouth, was closed. This followed the closure of the Anglesey plant in 2009.

An industry, that used to boast of production figures of 300,000 tonnes a year, is now reduced to the tiny Lochaber plant, rated at 43000 tonnes.

The reasons for these closures was well documented at the time, and the major one was high energy costs, largely due to UK climate policies.

The independent think tank, Civitas, published this report at the time:

The National Interagency Fire Center has now published its Annual Report for 2014.

Both the number and acreage of wildfires was below the 10-year average, although the Northwest (fires and acreage) and Northern California (acreage) were much above average.

The Rhone Glacier Then And Now

From HH Lamb’s Climate, History and the Modern World , page 215

I have shown this comparison of the Rhone Glacier between 1750 and 1950 previously. It is from HH Lamb’s “Climate, History and the Modern World”.

It show just how much of the glacier was lost prior to 1950.

 

I have unearthed some more photos, to help fill in the gaps.

 

rhoneglacier-1856

Back in 1856, Rhône Glacier almost reached Gletsch village down in the valley. View from the valley.

 

rhoneglacier-1870

In 1870, Rhône Glacier had retreated about half a mile
and lost considerably in thickness, but still leaped down to the valley

http://travelguide.all-about-switzerland.info/rhone-glacier-retreat-globalwarming.html

The glacier appears to be about as large in 1856 as it was drawn in 1750. But even by 1870 it had experienced a rapid retreat.

 

We can contrast the 1950 photo with one taken in 2009

They actually look pretty similar.

 

FOOTNOTE

The 19th photos come from a Swiss Tourism website, on a page titled “Global Warming Made Visible – Rhône Glacier Retreat”.

For some reason, they omit to show the 1950 photo!

They go onto explain why the glacier retreat is all your fault:

While a detailed prediction of ice-age cycles remains difficult, there is obviously a close correlation between carbon dioxide concentration and temperature. (For the detailed graph, see wikipedia)

But while the maximum natural carbon dioxide concentration used to be some 300 ppmv during the last three warm periods 200, 120000, 230000 and 320000 years ago, the carbon dioxide concentration has steeply risen to 375 ppmv since the beginning of the industrial age 200 years ago. This corresponds to an accelerated melting of glaciers in many regions of the world.

 

Has nobody told them that CO2 concentration increases AFTER temperatures rise?

DOHH!!
