Why is there so much preoccupation with atmospheric CO2 concentrations and reducing anthropogenic CO2 emissions when it is well documented in the peer-reviewed scientific literature that the CO2 contribution to the overall greenhouse effect is so weak that it can be easily supplanted by small changes in clouds and water vapor, or natural climate-changing constituents?

Climate Scaremongering Antidote: resisting the demonisation of CO2

While the search for a cure-all for CO2 alarmism continues, we shall, in the meantime, have to make do with piecemeal treatments to help young people cope with the deluge of woefully inadequate information relating to climate.

The problem is sometimes the information is wrong, but perhaps more common is a severe lack of balance.

The fact that the gentle overall warming of the last 150 years or so is generally very beneficial is not acknowledged,  whatever combination of factors has caused it.  Nor is the positive impact of higher ambient CO2 levels on agricultural productivity often recognised.

When your goal is to scare people to get their attention, I guess you don't want to dilute your messaging.  But we who don't care for their tactics nor their cause, need to be ready to respond to them, or at least help reduce the harm they must cause.

A new report from the GWPF provides parents and teachers with help to do that by providing an excellent background briefing on the benefits of CO2.

From their press release:

'... former IPCC delegate Dr Indur Goklany calls for a reassessment of carbon dioxide, which he says has many benefits for the natural world and for humankind.

Dr Goklany said: “Carbon dioxide fertilises plants, and emissions from fossil fuels have already had a hugely beneficial effect on crops, increasing yields by at least 10-15%. This has not only been good for humankind but for the natural world too, because an acre of land that is not used for crops is an acre of land that is left for nature”.'

There is also an excellent foreword from the extremely distinguished physicist, Freeman Dyson, who concludes (my italics, bolding and layout):

'Indur Goklany has assembled a massive collection of evidence to demonstrate two facts. 

First, the non-climatic effects of carbon dioxide are dominant over the climatic effects and are overwhelmingly beneficial. 

Second, the climatic effects observed in the real world are much less damaging than the effects predicted by the climate models, and have also been frequently beneficial. 

I am hoping that the scientists and politicians who have been blindly demonising carbon dioxide for 37 years will one day open their eyes and look at the evidence. Goklany and I do not claim to be infallible. Like the climate-model experts, we have also evolved recently from the culture of the cave-children. Like them, we have inherited our own set of prejudices and blindnesses. Truth emerges when different groups of explorers listen to each other’s stories and correct each other’s mistakes.'

Note added 15 Oct 2015.  The reformed ex-Greenpeace leader, Patrick Moore gave the GWPF Annual Lecture last night arguing we should 'celebrate CO2'.  Details via this link: http://www.bishop-hill.net/blog/2015/10/15/should-we-celebrate-co2-cartoon-notes-by-josh.html
