Climate & Climate Change

Clarifying the Role of the Sun and Global Temperatures

By

YESTERDAY atmospheric scientist, Professor Marvin Geller, explained to Leigh Dayton, science writer at The Australian newspaper, that the sun could not be driving “recent global warming as climate change sceptics claim” because solar radiation has not changed very much since 1978.  

But climate change sceptics do not claim there has been recent global warming.  They claim there has been a levelling off, or fall in temperatures, over the last 10 years since the 1998 El Nino-driven peak. [Click on the chart for a larger view of global temperature trends.]

As regards the El Nino event of 1998, according to Professor Geller, El Ninos cause a temporary increase in global temperatures, not the steady and consistent upward trend typical of warming from greenhouse gases like carbon dioxide.

But there has been no “consistent upward trend”.   

Indeed, Professor Geller misrepresents the position of global warming sceptics and the available global temperature data.

Save the Environment, Stop the Emissions Trading Scheme

By

Dear Friends and Colleagues,

I am writing to you as the Chair of the Australian Environment Foundation (AEF).  Over the last year a key issue for us has been the protection of River Red Gum forests in the Central Murray Valley of south eastern Australia.   At our recent conference and AGM in Canberra, members decided that the best thing we could do as an organisation for the environment over the next year would be to oppose the Emissions Trading Scheme (ETS). 

You might well ask why an environment group would oppose such a scheme.  Well, for three reasons:
1. An ETS  will not change the global temperature;
2. It will force many clean and green Australian industries overseas; and
3. It will make Australians poor, but it is richer, not poorer nations, that are generally better able to protect their natural environment.

DOES society benefit from a fear-driven science-funding policy that threatens the livelihood of scientists with the courage to argue against “orthodox” and established “beyond doubt” views on climate? 

The media drives this fear with increasingly hysterical messages that the earth is getting hotter, that this is being caused by human CO2 emissions and, that without radical social and economic surgery, we will face a myriad of global catastrophes, the like of which have not been seen since the dawn of our history.    We are told that all serious scientists agree with this and that those few who dissent are either charlatans or are funded by the fossil fuel companies.  Other dissenters are regarded on a par with creationists, Holocaust deniers or supporters of tobacco companies.  

But is this true?  Is the science really settled?

To answer this, Lawrence Solomon, the Canadian environmentalist and anti-nuclear campaigner, sought to find well-regarded scientists who disagreed with the AGW (anthropogenic global warming) hysteria promoted by Al Gore and the IPCC.

Blog about The Sun

By

Hi Jennifer,

I have recently taken over Carl Smith’s blog at http://landscheidt.auditblogs.com/

The site was originally set up to discuss Dr. Landscheidt’s work and is a good source of his documents. I am currently expanding the format to include any scientific work related to planetary influence on the Sun.

Ian  Wilson has just contacted me and gave permission to air his recent paper on the topic and I thought it and other articles may have been of interest to you and your readers.
