It's the Sun, Stupid (again)

You needn't be a climatologist to understand the statistical problems with manmade global warming theory. To say the last 200 years are the warmest in Earth's history (or equally disturbing assertions such as this decade is the warmest ever--laughable), it means you have to accept THEIR baseline--the level or range considered to be 'normal' that can then be used to show dramatic shifts--either up or down--in the data. Remember, the Earth is 4.5 billion years old, and humans have existed for a "gnat's length" comparatively. The Industrial Revolution--the genesis of the blame period that lasts until present day--was just about 200 years ago.

Finally, to acquire the baseline of normalcy, data (of which 150 years worth has now been deleted by the CRU at East Anglia) must be manipulated to account for numerous variables. So, they take 30 years of satellite observations, tree ring data, current day temperatures, and so on (each with their own potential measurement problems or SOURCES OF ERROR) and use computer models to produce the baseline of 200 years through which they claim to show we humans, through our modern ways, are heating the Earth to the breaking point. Never mind that they can IN NO WAY account for all the variables in the complex climate system. We can't even do it now with 100% certainty when predicting a hurricane's landfall point; we can only supply a probable range. We can't even accurately predict weather five days out, even with our technology and arrogant so-called 'brainpower.'

But the climate alarmist-scientist establishment doesn't want you to remember the Medieval Warm Period. They once produced graphs for the IPCC that omitted this period and tried to dream of ways to extricate it from history. You see...the Medieval Warm Period, where life really prospered before the follow-on mini ice age, is an INCOVENIENT TRUTH to climate alarmists.

The Sun. We are currently in a cooling trend on Earth that is measurable. The Sun, consequently, has some of the lowest measureable activity in recent history. Coincidence? That's hard to swallow.

The paper highlights a few scientists, including Professor Henrik Svensmark, a physicist at the Danish National Space Center in Copenhagen, who said the recent warming period was caused by solar activity.

Svensmark said that the last time the world experienced such high temperatures, during the medieval warming period, the Sun and the Earth were in a similar cycle.

Professor Nils-Axel Morner, a geologist from Stockholm University, said sea-level rise has also been exaggerated by the "climate alarmists" using computer models.

He said observational data from lake sediments, coast lines and trees show sea levels have remained stable.
