Earth Observatory articles

These things make an ideal intro to earth science. …

Atmospheric CO2 concentrations have been measured since 1957 at Mauna Loa. It has increased about 0.3% per year because of fossil fuel combustion. CO2, a nutrient, is the leading indicator of other global scale human impact.

In July 1983, NASA published the Land-Related Global Habitability Science report on how the entire earth could monitor global change. The Earth Observing System, EOS was conceived in 1990. In 1999 they launched their first satellite.

Population increases mean impact on the biosphere will increase. Per capita, resource consumption is increasing as developing states catching up with standards of developed countries, developing whatever the environmental cost.

A global economy is a global environment. The sustainability of human life on Earth cuts across all politics. We all want the best for our grandchildren.

Global biospheric health is measurable, discussions and policy development no longer handicapped by lack of data. EOS provides information on trends of change in our biosphere. How we interpret data and our action in the next millennium is critical:
If trends have modest change, then only small adjustments in social behaviour may be necessary.
If impacts appear harmful and accelerating unpredictably, can we ignore these early warnings?

Politics must be based on facts, not conjecture. Global habitability has immediate significance to us all.

[Increases of “about 0.3% per year” are increases of about 30% per century. That is not only unsustainable, it is ridiculous. Is that 50 ppm in 40 years?]

  1. Précis.Practice perfects but finding out what others have to say about a subject is a way to learn too. But the mind can be distracted.Tip:Note what you have found. It would be counter-productive to just copy anything verbatim. To get the gist of something, pare it down to the bare bones.It concentrates the mind, ensures you get the ideas and leaves you with notes to recollection. The original may be incorrect but without the initial information, one can not criticise the ideas put forward.It is with this in mind that I have set about making précis of Earth Observatory articles. To cut an essay down to one third you have to be brutal. But unless you aim for 1/3 you don’t have a real précis. Good intentions don’t count.I clipped them with Opera Browser but the links were not retained. (They point to my C drive instead.)I got them with Internet Explorer from a public library and saved them as .MHT files. If I save them as .HTM they come with folders I tend to lose when saving to different locations.Why am I posting them when they can be read in full just as easily?They serve as aide memoires and because this blog is all about geophysics.I have done as much with scientific PDFs as far as I can. But theses and similar scientific papers are not easily digestible, so having the EOS articles helps cross references.(If I can just remember to tag them correctly.)Ooh! Nice one!I have just discovered that Opera allows me to save a web page as a text file. It even allows you to open it with the office tool of choice. (I have Open Office 3.2 and Word 97. On my Ubuntu drive I have AbiWord and Open office 3.whatever. (Both open Word files, so what am I to do?))
