Dear Pope you will shortly be receiving a letter from a wolf in sheep's clothing, advise check for paw prints before opening.

The first thing to say about this letter is the astonishingly ignorant religious and cultural provincialism that mis-informs it. A provincialism that is essentially rooted in a 19th century Victorian clock-work world-view. A provincialism that fails to take into account the fact that we now live in a Quantum world where everybody and everything is instantaneously inter-connected.
A "religious" provincialism that wrongly pretends that its entirely reductionist Biblical religiosity provides the only means for understanding what we are as human beings, our relationship to everyone and everything that we presume to be "not self", and our relationship to Reality altogether, or the centerless and boundless Beautiful Room of Perfect Space or Conscious Light in which all of this is floating.

That having been said why not google the topic Buddhism and global climate change - one of the first references that comes up is this one: http://www.ecobuddhism.org

Plus a set of essays which challenges (and blows away) the dim-witted now archaic "religious" and cultural provincialism that mis-informs the one-dimensional reductionist world-view promoted by the dreadfully sane folks from the Cornwall outfit:

When I see something described as an "open letter" I think 'boring', 'naive', 'ideological'. When it is addressed to the Pope, as a non-religious person, I really clench up, even though I believe the Pope is a decent fellow and a well-meaning human being.

I did, however, read what was said by my esteemed fellow posters, and it appears that I was right to again ignore this weird, group method of 'communication' which the 'recipient' is unlikely to see.

In 1900, global population was about 1.6 billion. There were two major developments in the 20th century that dramatically increased agricultural productivity, the Haber-Bosch process, the ultimate source of nearly half the nitrogen in your body, and the Green Revolution, which doubled and in some cases tripled grain production per hectare. If the population had stayed at 1.6 billion, then every human being on Earth could have had a decent First World standard of living, with plenty of room for the other species to live too and no need for land degradation or destabilising the great natural cycles that support life on Earth.

What happened, of course, is that humans, cheered on by the Roman Catholic Church, blew out the population to more than 7 billion now and 10-11 billion (UN medium projection), and possibly even more, in the future. As Prince Philip once put it, "They decided to feed more hungry people, rather than feeding hungry people more." Many countries have seen the light and reduced their fertility rates, and some have even stabilised their populations. Others have not and are well on the way to becoming failed states. See

and look up the fertility rates of the countries discussed if you doubt this.

We live on a finite earth where resources and the capacity of the environment to safely absorb wastes are not unlimited. Instead of trying to discredit the scientists, who may not know everything, but surely do know more about the climate than the authors of this letter, perhaps they (and the Pope) should work on persuading the poor not to contribute to their own poverty.

Meanwhile why not google Cornwall Alliance and Right Wing Watch?
The essay on the People For the American Way website titled: slaying the green dragon, how the religious right and the corporate right are joining forces .... provides all the necessary background for understanding the origins and purposes of the Cornwall Alliance.

A delightful letter, requesting that His Holiness advert to the truth about climate change.

The IPCC took some laboratory science about the effect of carbon dioxide and fed it into computer modelling of our climate.

The results of the computer modelling, when compared with observations of actual climate, showed conclusively that the models are a failure.

At a time when the models showed that global warming would increase, because of the proportion of CO2 in the atmosphere,global warming has stopped.

Human emissions have no measurable effect on climate. It is fraudulently asserted by the IPCC that CO2 causes catastrophic global warming.

There is no basis to assert that it will cause global warming, and there is no rational basis to assert that global warming would be harmful, and not beneficial, as it has been in the past, for example, in the medieval warm period.
