Make Me a Model

Statistical analysis of the raw data on Global Warming suffers from two major pitfalls :-

1. You are looking at the combined effects from several causative sources. Unless you have the means to distinguish the various factors, you cannot apply statistical techniques to the data and expect to get anything truly meaningful out. All that can be said, at best, is, “The Globe. Still Warming.”, as the warming trend over a long enough period of time has managed to stand out over the short-term variations.

2. Looking at the data purely by eye, some of the warming or cooling effects are clearly short-term, others longer-term; so picking a range of years/months/seasons at random, or according to some bias, is likely to distort the analysis. This is known as “cherry-picking”. The results of cherry-picking include the fallacious and discredited claim that, “Global Warming stopped in 1998”, or the much more crafty and misleading, “There has been no statistically significant Global Warming since 1998”.

Some researchers are content just to point to the overall effect of the raw data – global temperatures on land and at sea are rising sharply and the charts should be sufficient to understand the basic problem.

However, some people still contest that Global Warming is taking place, or that if it is, it isn’t serious. This then, is the cue to do an in-depth analysis into the known factors in global temperatures, and to attempt to “deduct” obvious short-term warming and cooling features in order to eyeball the underlying trends :-

Unqualified Opinion (1) : Dan Gardner

There are several journalists out there who simply can’t cope with the real risks posed by dangerous Climate Change.

Following a rather reasonable, rational article by Louise Grey, Tom Chivers gave the “loaded dice” metaphor to straighten her up on language :-

https://www.telegraph.co.uk/news/worldnews/asia/pakistan/7937269/Pakistan-floods-Climate-change-experts-say-global-warming-could-be-the-cause.html

“Pakistan floods: Climate change experts say global warming could be the cause : The world weather crisis that is causing floods in Pakistan, wildfires in Russia and landslides in China is evidence that global warming predictions are correct, according to climate change experts. : By Louise Gray, Environment Correspondent : Published: 10 Aug 2010 : Almost 14 million people have been affected by the torrential rains in Pakistan, making it a more serious humanitarian disaster than the South Asian tsunami and recent earthquakes in Kashmir and Haiti combined. The disaster was driven by a ‘supercharged jet stream’ that has also caused floods in China and a prolonged heatwave in Russia. It comes after flash floods in France and Eastern Europe killed more than 30 people over the summer. Experts from the United Nations (UN) and universities around the world said the recent “extreme weather events” prove global warming is already happening. Jean-Pascal van Ypersele, vice-president of the body set up by the UN to monitor global warming, the Intergovernmental Panel on Climate Change (IPCC), said the ‘dramatic’ weather patterns are consistent with changes in the climate caused by mankind. “These are events which reproduce and intensify in a climate disturbed by greenhouse gas pollution,” he said. “Extreme events are one of the ways in which climatic changes become dramatically visible.”…”

[ YouTube Credit : The link to the video above comes thanks to the endeavours of that most fair and balanced individual James “no net global warming since 1998” Delingpole. “No net global warming since 1998” ? James ! You’re quoting Pat Michaels, but did he perhaps make that up ? Or was it something that Christopher Monckton might have made up ? ]

The BBC puts the blame on Climate Change – almost – in a report on the Russian heatwave-wildfire disaster.

But they just can’t bring themselves to admit it as an organisation – and put the claims into the mouths of others – using quotation marks in the headline (‘partly to blame’) and ascribing the opinion to “researchers”, the “UK Met Office” and “experts” :-

https://www.bbc.co.uk/news/science-environment-10919460

“10 August 2010 : Climate change ‘partly to blame’ for sweltering Moscow : By Katia Moskvitch : Science reporter, BBC News : Global climate change is partly to blame for the abnormally hot and dry weather in Moscow, cloaked in a haze of smoke from wildfires, say researchers. The UK Met Office said there are likely to be more extreme high temperatures in the future. Experts from the environmental group WWF Russia have also linked climate change and hot weather to raging wildfires around the Russian capital. Meteorologists say severe conditions may linger for several more days…”

Well, I’ve got a bit of a question to pose – it might not be possible to ascribe the current weather conditions in Russia (and Pakistan and China and and and…) to Climate Change, statistically. I mean no one weather event can be said to have been caused 100% by Climate Change. But would these extreme weather events have happened without Climate Change ?

That is by far the most important question to ask, and Michael Tobis does just that :-

https://initforthegold.blogspot.com/2010/08/moscow-doesnt-believe-in-this.html

“…Are the current events in Russia “because of” “global warming”? To put the question in slightly more formal terms, are we now looking at something that is no longer a “loading the dice” situation but is a “this would, practically certainly, not have happened without human interference” situation? Can we phrase it more formally? “Is the average time between persistent anomalies on this scale anywhere on earth in the undisturbed holocene climate much greater than a human lifetime?” In other words, is this so weird we would NEVER expect to see it at all?…”
