Like I said, severe prolonged cold weather is the major control on beetle populations. There's a direct link between the massive growth in beetle population, their extent and the milder winters of the last couple of decades. Growing up in Prince George and Williams Lake BC and having several...

The beetle outbreak is a reliable indicator of the local changes in climate in BC in the last several decades due to overall climate change. The massive outbreaks which cover much of the province now would not be occuring if not for recent warmer winters which do not provide the necessary...

The beetles were there, they were just there in much more limited numbers, some years saw beetle outbreaks but severe winters would cause massive diebacks. The beetles produce the glycol anit-freeze because they are adapted for a cold climate, their numbers have taken off because the natural...

Cold has been the historical control, the beetles produce natural glycols(anti-freeze) and hibernate under the pine bark to survive the winter. If you get cold enough weather early/late in the season that can cause significant dieoff, once the beetles are established in their hibernation it...

Human activity certainly added to the problem, but from what I understand it's the lack of cold enough temperatures to reach the beetles while they're hibernating under the bark that has led to the explosion in numbers. BC Parks was slow to allow preventative cutting and slash and burn to...

The major control on pine beetle is very cold weather. They produce natural anti-freeze and need prolonged periods of cold(minus 30 celcius or more to start killing significant numbers). The last winter that had the necessary conditions was more than two decades ago in 1986, I remember it well...

Global climate change is already happening, just travel to BC and see what a lack of cold winters has produced, and the pine beetle have crossed the rockies and are hitting hard here in Alberta now. It's lack of political will that's preventing any meaningful comprehensive programs to mitigate...

Interesting, melting water also played a major role in the breakup of the Larsen B iceshelf in Antartica, which was expected to survive much longer. It's also acting to accerlerate the movement and erosion of the Greenland icecap.

The projection is for the Arctic to become ice free in the summer within several decades(maybe as little as one), not during the winter.

Bingo. As the Inuit are finding out the pack ice is getting a lot thinner and seems to be melting from the bottom due to warmer ocean temperatures. Pack ice can be several hundred feet thick at pressure ridges, sea ice thickness is measured in feet. Walter seems to have a tough time...

And the rush to claim territory in the Arctic currently under pack ice that may have rich natural resources is due to what? Last year saw the greatest number of craft transit the Northwest Passage and China is building icebreakers in anticipation of saving 7000 miles in shipping products to...

Disseminate, distract, confuse and accuse: these are the tried and true methods to discredit and/or obscure the scientific consensus on any situation that could potentially hurt the bottom line of major economics concern in recent history. The fact is the peer reviewed research on climate...

Maybe they understand it's all linked, you don't need to take much biology to understand just how deeply connected all species are and how fragile the web can be when many links are cut. I'm originally from BC and watched how the pine has disappeared there, the amount of preventative cutting...

What facts would those be, the nonsense being generated by psuedo-scientists like Singer being funded by companies like Exxon/Mobile or the real science that's been accumulated for decades on the link between human activity and climate change. I can't do any better than Avro and the massive...

I always laugh when the people who are trying to save us from ourselves are portrayed as the bad guys. All those evil people trying to protect water, air and soil quality... and now the overall global climate itself... shame on you.:lol:

Olly the Ostrich is going to get bit on the butt by Leo the Global Warming Lion.:lol:

An ice age occures when the annual snowfall exceeds the rate of melting, more land gets covered in snow and ice and more sunlight gets radiated back into space from the highly reflective surface. As the overall climate cools the atmosphere has less ability to hold water vapour so less energy is...

The same kind of dinks who spent a couple decades trying to convince us that 'smoking really isn't all that bad for you' are working hard to do the same with Climate Change. First... 'It's not really happening so we don't need to do anything about' then 'Well the climate may be changing...

Exactly or the US southwest which is getting even hotter and drier. These massive forest fires keep happening people won't have to worry about cooling their homes in a lot of places.

Is there a way to make our Parlimentary system work in it's current form or is it time to change to another democratic system such as a Republic like the US? In recent years we've seen how a minority government has abused it's powers and manipulated the Parliment and the media in an attempt to...
