We trusted them

We must change our path, but not as the alarmists would have us believe.

Now we must change direction, but following reason, not fear.

About thirty years ago we first heard reports that the world was warming. The scientific papers noted that levels of atmospheric carbon dioxide were the highest recorded in the last 8 million years (or some large number, depending on the study). The language made it seem that CO2 caused the warming, but it seldom said so directly. At first.

We trusted the scientists and as more and more of these papers appeared we slowly came to accept that the planet was warming because of our CO2 emissions. Continue Reading →

Wind and waves scatter sea ice, not AGW

Antarctic sea ice

Antarctic sea ice can be breathtaking.

Waves chase away warming

A paper has arrived from NIWA that says, in effect, warming is not necessary to explain the disappearance of much sea ice. That it removes a warming element from the polar pieces of the global warming puzzle gives me great pleasure. Well done, them!

I’m talking about “Storm-induced sea-ice breakup and the implications for ice extent” (Nature 509, 604–7), published online in Nature on 29 May, by A.L. Kohout, M.J. Williams, S.M. Dean and M.H. Meylan (KWDM). Its major discovery is that large waves travel much farther through pack ice than hitherto realised, thus breaking up much more ice than we realised and allowing it to be swept away by wind and wave—it hasn’t been melting from the heat of global warming.

Nature is the latest living God

\ 37 Comments \ by

I’ll keep this simple, to avoid ecclesiastical clashes. Last thing I want is a fight to break out between science and religion. Oh, wait …

First, a reader, Rob Taylor, said:

So, in denier fairyland, this all balances out, somehow? Let’s see – crippling drought in one place, horrendous floods in another simply shows that all is hunky-dory?

Then I said:

“Who could approve of them, you twit? But this is Mother Nature. This is God’s will. There’s nothing new here – not for thousands of years. This is life. This is how it goes.”

Another reader, Nick, said:

“this is Mother Nature. This is God’s will” – is that really what you believe? I had been conducting these discussions on the assumption everyone accepted that science rather than divine intervention could explain the weather. Please correct me if my assumption is false. Does anyone else here think that any changes in the climate are “Gods will”?

My meaning here was perverted and then Nick hijacked it. However, together they raise an arguable point about our relationship with our surroundings, so let me explain. Rob made out that we can prevent these natural disasters. His mistake was in believing that we have sufficient influence on the weather to ameliorate droughts and floods. It’s a nutty idea and we don’t. Continue Reading →

More Antarctic melting threats

Part of the mighty West Antarctic Ice Sheet, pinned to the continent by a series of mountains along the sheet’s ocean boundary. With an area of 2 million square km, it’s the size of Texas, 2.2 million cubic km, up to 14 km thick, weighs 1870 trillion tonnes and it’s crushing the crust of the Earth a full kilometre into the raw, molten mantle. This puppy’s going nowhere fast. Melt it? Hah. We could chuck our spare nuclear weapons at it and the ice would survive – though it’d make just the “coolest” firestorm.

A five-year study just published says methane hydrates buried under kilometres of Antarctic ice and sediment could accelerate global warming if released into the atmosphere. This has given the warmists much grist for their mills of alarm.

The paper, Potential methane reservoirs beneath Antarctica, published on 30 August as a letter in Nature, is behind a paywall, so I’ve only seen the abstract and Supplementary Information (pdf).

The paper contains some interesting information. The sediments are in surprisingly deep basins – down to 10 km or even 14 km in rifts (measured from the earth surface, not the top of the ice), although most are between 0.3 km and 3 km deep. That’s a lot of silt. The amount of overlying ice is similar, from 1 km to 3.5 km. That must all melt before the sediment has any hope of warming enough to release the methane clathrates. Chance would be a fine thing. Continue Reading →

Sea level raises funding hopes

\ Leave a Comment \ by

A worrying story surfaced recently of yet another proclamation that global warming grows and grows. The headline was “Rate of Sea Level Rise Increasing“.

That’s scary, and it sounds like a new result, doesn’t it? Well, it isn’t. It raises fears only as a means to raise funds.

It appeared at SciencePoles, the web site of the International Polar Foundation.

It said a new study in Nature announces that global mean sea-level change has increased from a few centimeters per century over recent millennia to a few tens of centimeters per century in recent decades. Moreover, quoting the abstract, they say: “This tenfold increase in the rate of rise can be attributed to climate change through the melting of land ice and the thermal expansion of ocean water.” The mere mention of “climate change” means it’s our fault, and it’s there to alarm us.
