A brief run-through of some of the problems with ‘man-made warming’ theories, which so often get swept under the carpet and treated as unmentionable.

One of the main accusations launched by climate activists is that anyone arguing against man-made global warming is “anti-science.”

They tell us that the science is “settled,” and that anyone who objects is ignoring a blindingly obvious set of facts.

But what to do about someone like me, asks Steven Wright in Climate Change Dispatch?

The ITCZ is the central band of bright white clouds in this composite image [credit: NASA]


This seems to add weight to the idea that the moving position of the ITCZ can be a useful indicator of natural climate change, in conjunction with other data sources.

The tropical rain belt, also known as the Intertropical Convergence Zone (ITCZ), is in a state of constant migration, as Phys.org reports.

It continuously changes position in response to the seasons and follows the sun’s zenith, with a slight delay. This in turn determines the wet and dry periods in the tropics and subtropics over the course of the year.

The tropical rain belt therefore effectively controls the climate in most of the tropical and subtropical regions, such as the monsoon season in Southeast Asia and Central America.

An international team of researchers led by Franziska Lechleitner from the Geological Institute at ETH Zurich has proven for the first time that the migration of the tropical rain belt is quite sensitive to even small changes in global temperatures.

Interesting historical round-up from Paul Homewood, which concludes:
‘There is no written law of nature that says glaciers should be the size they were in Victorian times.’

Indeed.

NOT A LOT OF PEOPLE KNOW THAT

From HH Lamb’s “Climate, History and the Modern World”

We know that sea levels have risen since the late 19thC, and that much of this is due to melting of glaciers and ice sheets. However, we also know that the same glaciers were growing rapidly during the Little Ice Age, so can we say that 20thC sea level rise is anything other than a natural process?

Let’s remind ourselves of just how great and widespread this glacial advance was.

The history of glacial advance in the European Alps is well documented. Historian, Brian Fagan, offers us this horrifying account:

Another story from the ‘Climate change causes everything’ file. Fortunately Colombia has not over-reacted.

TODAY VENEZUELA – Venezuela tried to downplay its illegal entry of troops into Colombia this week by claiming the constantly changing direction of a river near the border accidentally led the soldiers beyond their jurisdiction.

Foreign Minister Delcy Rodriguez said the Venezuelan soldiers entered Colombia’s eastern department of Arauca as a result of the Arauca River, which she said is constantly changing its flow and direction.

A diplomatic commission still has to clarify the incident, which is reportedly expected in the coming hours.

Basing all government climate research funding on one narrow theory was never a smart policy.
H/T GWPF

Prominent scientists operating outside the scientific consensus on climate change urged Congress on Wednesday to fund “red teams” to investigate “natural” causes of global warming and challenge the findings of the United Nations’ climate science panel.

The suggestion for a counter-investigative science force – or red team approach – was presented in prepared testimony by scientists known for questioning the influence of human activity on global warming.

It comes at a time when President Donald Trump and other members of the administration have expressed doubt about the accepted science of climate change, and are considering drastic cuts to federal funding for scientific research.

From Activist Post, by Derrick Broze

At a recent geoengineering conference two Harvard engineers announced plans for a real-world climate engineering experiment beginning in 2018.

The science of geoengineering has increasingly become a part of the public conversation around climate change and an ever-controversial topic within the scientific community. Geoengineering is a type of weather modification (or climate engineering) which has been researched, but, until recently, has been considered too unpredictable to attempt on a large scale.  According to a 2013 congressional report:

The term ‘geoengineering’ describes this array of technologies that aim, through large-scale and deliberate modifications of the Earth’s energy balance, to reduce temperatures and counteract anthropogenic climate change. Most of these technologies are at the conceptual and research stages, and their effectiveness at reducing global temperatures has yet to be proven. Moreover, very few studies have been published that document the cost, environmental effects, socio-political impacts, and…

No doubt both sides in the UK-EU negotiations will have their ‘wish lists’ but can the EU dictate British policies?

The UK will have to abide by EU environmental and climate change standards in order to conclude a future trading agreement with the rest of the trading bloc, according to a leaked European Parliament paper seen by Utility Week.

A draft resolution, setting out the parliament’s parameters for EU-UK negotiations on the latter’s withdrawal from the union, identifies the environment and climate change as two areas where common benchmarks must continue to apply.

The warmist AAAS sucks lemons in advance of the US Senate climate change hearing next week. They resent his ‘agenda’ as it opposes theirs.

Representative Lamar Smith (R–TX) rarely expresses his true feelings in public, says the AAAS.

But speaking yesterday to a like-minded crowd of climate change doubters and skeptics, the chairman of the science committee in the U.S. House of Representatives acknowledged that the committee is now a tool to advance his political agenda rather than a forum to examine important issues facing the U.S. research community.

“Next week we’re going to have a hearing on our favorite subject of climate change and also on the scientific method, which has been repeatedly ignored by the so-called self-professed climate scientists,” Smith told the Heartland Institute’s 12th annual conference on climate change in Washington, D.C.

Once America’s new leader poured cold water on the Paris ‘deal’ it didn’t take some (all?) of the other G-20 members long to get cold feet about stumping up the ‘pledged’ cash. Looks like the political showboating was just that. Who is surprised any more by this well-worn routine?
H/T GWPF

Finance ministers for the U.S., China, Germany and other members of the Group of 20 economies may scale back a robust pledge for their governments to combat climate change, ceding efforts to the private sector.

Citing “scarce public resources,” the ministers said they would encourage multilateral development banks to raise private funds to accomplish goals set under the 2015 Paris climate accord, according to a preliminary statement drafted for a meeting that will be held in Germany next week.

The statement, obtained by Bloomberg News, is a significant departure from a communique issued in July, when finance ministers urged governments to quickly implement the Paris Agreement, including a call for wealthy nations to make good on commitments to mobilize $100 billion annually to cut greenhouse gases around the globe.

US Environmental Protection Agency (EPA) chief Scott Pruitt


BBC News all but bursts a blood vessel over the EPA head’s opinion that the climate science ‘debate’ is not settled. Their reaction is to trot out some standard warmist platitudes, which surprises nobody.

US Environmental Protection Agency (EPA) chief Scott Pruitt has said he “would not agree” carbon dioxide is a primary contributor to global warming.

He told CNBC that measuring human impact on the climate was “very challenging” and there was “tremendous disagreement” about the issue.

Mr Pruitt instead insisted that officials needed “to continue the debate” on the issue. His remarks contradict his own agency’s findings on greenhouse gas emissions.

The El Niño of 1997-8


The report says ‘the possible return of El Niño this year would present a unique situation’. Is there still excess heat in the system as sunspots go further into ‘quiet mode’?
H/T GWPF

The path to another round of El Niño in 2017 appears to be shortening, as tropical Pacific Ocean waters have been warming at a substantial rate. Several models suggest that El Niño could be comfortably in place as early as May.

Weather forecasters have been eyeing for a couple of months a possible return this year of El Niño, which normally comes around every two to seven years and last occurred in 2015/16.

Arctic sea ice [image credit: cbc.ca]


Variations of this aerosol claim have been around for many years. These researchers seem uninterested in known oceanic cycles which might help to explain the observed temperature changes, instead relying on climate models. But another researcher notes that ‘black carbon emissions in some parts of the Arctic are still quite common’, as confirmed recently here. An earlier study (2007) reported ‘There is, however, at least a fourfold uncertainty in the aerosol forcing effect.’ So it looks like the jury is still out regarding air pollution in the Arctic.

Humans may have been altering Arctic sea ice longer than previously thought, according to researchers studying the effects of air pollution on sea ice growth in the mid-20th Century.

The new results challenge the perception that Arctic sea ice extent was unperturbed by human-caused climate change until the 1970s, reports Phys.org. Scientists have observed Arctic sea ice loss since the mid-1970s and some climate model simulations have shown the region was losing sea ice as far back as 1950.

In a new study, recently recovered Russian observations show an increase in sea ice from 1950 to 1975 as large as the subsequent decrease in sea ice observed from 1975 to 2005.

It looks more like ‘winding down’ at this stage, but ‘scrapping’ eventually. Not unexpected, if it goes ahead as suggested.
H/T Europe Breaking News

Donald Trump is poised to eliminate all climate change research conducted by Nasa as part of a crackdown on “politicized science”, his senior adviser on issues relating to the space agency has said.

Nasa’s Earth science division is set to be stripped of funding in favor of exploration of deep space, with the president-elect having set a goal during the campaign to explore the entire solar system by the end of the century. This would mean the elimination of Nasa’s world-renowned research into temperature, ice, clouds and other climate phenomena.

It should be harder for NOAA to brush this off than it was when the last President was in office.
H/T GWPF

Revelations by the Mail on Sunday about how world leaders were misled over global warming by the main source of climate data have triggered a probe by the US Congress.

Republican Lamar Smith, who chairs the influential House of Representatives Committee on Science, Space and Technology, announced the inquiry last week in a letter to Benjamin Friedman, acting chief of the organisation at the heart of the MoS disclosures, the National Oceanic and Atmospheric Administration (NOAA).

He renewed demands, first made in 2015, for all internal NOAA documents and communications between staff behind a controversial scientific paper, which made a huge impact on the Paris Agreement on climate change of that year, signed by figures including David Cameron and Barack Obama.

Map of Scottish woodlands


A related issue is that Scottish woodland is currently being invaded by an army of wind farm constructors whenever they get the chance.

The SNP’s plans to increase the amount of woodland in Scotland in an attempt to fight climate change risks damaging the nation’s “dramatic open views and vistas”, according to mountaineering and gamekeepers groups.

The Scottish Government has proposed increasing the amount of woodland cover from 17 per cent to 25 per cent by 2050, with a commitment to planting 10,000 extra hectares of trees between now and 2022 included in its draft Climate Plan, as iNews reports.

But Mountaineering Scotland and the Scottish Gamekeepers Association (SGA) are concerned that the changes could damage the nation’s wild moorland, arguing it forms a crucial part of Scotland’s “unique” landscape.

If not, then certainly mildly irritating to some people anyway. 😎
H/T GWPF

The word “cult” may be a little over the top, but whatever it is, it sure isn’t science, says The Manhattan Contrarian.

Will Happer is an eminent physicist at Princeton who has chosen (along with his colleague Freeman Dyson) to plant a flag on the skeptic side of the climate debate. I’ve had the pleasure of meeting Happer on a couple of occasions.

Recently his name has been floated as a potential candidate for the position of Science Advisor to President Trump. (This is the position that has been held by eco-fanatic John Holdren during the Obama presidency.)  Although it is not final, and others remain in the running, Happer has said that he will take the position if offered.

Yesterday Happer gave an interview to the Guardian newspaper. When it came to the issue of “climate change,” Happer didn’t pull any punches.

NOAA have a good account of what has been going on with the Oroville Dam:

As mentioned previously in the Event Tracker, California is going through one of its wettest water years (October – September) on record. In particular, precipitation so far in 2017 is on a record pace for northern and central California. While the water has been a godsend in reducing and relieving drought conditions, it also has been too much of a good thing as flooding has resulted. One case in particular is the ongoing emergency at the Oroville Dam north of Sacramento. Tremendous amounts of precipitation have led to the Lake Oroville reservoir—the second largest reservoir in the state—to fill past capacity. The need to funnel water out of the reservoir and accompanying complications has led to flooding concerns and evacuations below the dam.

It is just over a year since Storm Desmond brought devastating floods to Carlisle.

Soon after the Carlisle Flood Action Group was formed, and they have now published a very full and highly technical account of the floods.

This is the first part of the Executive Summary:

Although Storm Desmond was severe by any account (and the report later accepts that it may have been exacerbated by global warming), the real problem was lack of river maintenance and poor management. This of course is a rerun of the Somerset floods in 2014.

One letter changes in the new US climate policy: ‘defund’ replaces ‘defend’. Interesting times ahead.
H/T GWPF

US president Donald Trump will honour his campaign pledge to pull the US out of the Paris climate agreement and defund UN climate programmes, a former adviser to the new administration has said.

Myron Ebell served as head of the Environmental Protection Agency’s (EPA) transition team from early September until 19 January, when he helped to draft an advisory action plan on how to implement Trump’s campaign promises.

At a press briefing held by the Global Warming Policy Foundation (GWPF) and the Foreign Press Association (FPA) in London today, Ebell declined to divulge any details of the EPA document on the grounds that it is confidential.

But Ebell, a well-known climate change sceptic and head of the Competitive Enterprise Institute’s (CEI) energy and environment centre, outlined Trump’s “very clear” promises on energy and the environment that he is convinced the new president will honour.
