Real Climate Science

While there is much room for debate, challenging the complex science or its conclusions from any one dimension is unacceptable, whether by focusing on one variable, a limited time window, or via anecdotes, or limited personal observation. I, for one, accept the peer-reviewed science but would not be surprised if forecasts shift a great deal in the years ahead. In view of all of the above, policy makers need to be careful.

Almost as warm as 1927, 1925 and 1953. Only a degree cooler than 1911.

The heat is unbearable in Texas, and millions of climate refugees are bee-lining it to Manitoba for the winter.

At 0C, a body of fresh water will exist at equilibrium in the three phases solid-liquid-gas, with a vapor pressure of 1/100th of an atmosphere. That is exactly what we measure on Earth. Anyone who has ever had a drink with ice in it, is aware of the fact that the three phases can exist together. Water, ice and vapour condensing on the glass.

If you are above 0C, all the ice will eventually melt. If you are below 0C, all the liquid water will eventually freeze.  Vapour will be present at any temperature above absolute zero. There is only one temperature where you can have all three in equilibrium.

Other gases in the atmosphere increase the total pressure, causing the freezing point to depress by a tiny fraction of a degree. The phase diagram is not an exactly 100% perfect representation of the system because of the presence of other gases – but it is close enough.

Why do dim-witted alarmists keep bringing this up?

Nothing but top-notch science!

Penn State University has now completed its investigation of climate research Michael Mann with respect to “ClimateGate”–and sure enough, it’s an exoneration. My understanding is that the report, which releases at 330 pm today, can be found here.

You’ll recall that Mann had previously been found clean on three other counts; the remaining question being looked into was whether Mann had engaged in any actions that “seriously deviated from accepted practices within the academic community for proposing, conducting, or reporting research or other scholarly activities.”

And now, the answer is no. The ClimateGate vindications just keep on coming….all smoke, no fire, thus far–and probably always.

The remains of the farms and churches of the Norse are found
throughout South Greenland. The large granite and sandstone blocks at the ruins have many good stories to tell. The oldest is about Erik the Red who was banished from Iceland in 982.

Back then, the climate was milder than it is today.

Animal bones and other materials collected from archaeological sites reveal Icelandic Vikings had large farmsteads with dairy cattle (a source of meat), pigs, and sheep and goats (for wool, hair, milk, and meat.) Farmsteads also had ample pastures and fields of barley used for the making of beer and these farms were located near bird cliffs (providing meat, eggs, and eiderdown) and inshore fishing grounds. Fishing was primarily done with hand lines or from small boats that did not venture across the horizon
