Taxing the very air we breathe

New Zealand’s Emissions Trading Scheme (ETS)—will it reduce global warming?

We breathe carbon dioxide and without it we would die. Growers routinely add it to greenhouses (four times the normal level) to make the plants grow better. Forests are growing measurably faster as the level of atmospheric CO2 climbs.

But human emissions of CO2 are allegedly warming the planet. Inducing a sense of guilt for driving a car or turning the lights on hasn’t reduced emissions. An alternative way to force emissions down is to create emission licences (or carbon credits) and then buy and sell them to each other. Entrepreneurs love it. New Zealand is setting up such a scheme right now. Continue Reading →

Unending global warming hyperbole finally too much

References in the news media to global warming and its dire consequences are frequently inexact, unbalanced and unnecessarily alarming—sometimes even wrong. Their endless repetition is tiresome. Also they are dangerous, in that people disinclined to check for themselves will inevitably start to believe them. New Zealanders deserve better. Continue Reading →

Tourism to be Ravaged by Global Warming?

The Editor,
NZ Herald.
4 January, 2008.

Dear Sir,

Is our hard-won tourism industry to be ravaged by global warming?

No, not by rising sea levels, but by imposts to “offset” the “carbon footprints” of the growing numbers of our visitors? Let us hope that cool heads examine the matter carefully before hasty action spoils anything.

According to research from the University of Otago published in the NZ Herald today, visiting tourists’ CO2 emissions equal those from all our coal, gas and oil-fired electricity generators combined. Continue Reading →

No more global warming?

It’s been repeated so often that by now we take it for granted. The world’s climate is warming up and is starting to produce bad consequences which will worsen.

We’re told sea levels are rising, icecaps are melting, glaciers are disappearing and storms are intensifying. Polar bears are at risk because the ice they know and love is shrinking, tropical diseases are about to spread everywhere and we’ll soon be growing coconuts in Bluff.

Get ready for shorter ski seasons and be very cautious about buying seaside property. Continue Reading →

The hockey stick

Here’s a story you haven’t heard, and you should have. An analyst, working for the government, uses computers to crunch numbers and find the truth. Let’s call him “Mann.” The trouble with Mann is, he has an ideology. He knows what he wants his results to be. more…

South Pacific coral reefs—history

Recent major bleaching events on coral reefs of the South Pacific are not unusual. Earlier, higher sea surface temperatures did not cause dramatic bleaching and did not destroy the reefs. They regularly reconstruct themselves. more…

original source added 1 Jan 2024:

In conclusion, substantial evidence indicates recent major bleaching events experienced by coral reefs of the South Pacific Ocean are not as unusual as recent observations might seem to imply, as much longer records reveal instances of similar bleachings in prior centuries. In addition, there is substantial evidence for much earlier greater-than-present sea surface temperatures that did not elicit dramatic bleaching; and when such bleaching has occurred, it typically has not spelled the end of the reefs involved, for many of them have regularly reconstructed themselves in their own prior image.
