16 What do Canadian climate scientists say?
Some impacts are: Inadequate water for Prairie agriculture and hydroelectric utilities due to increased drying of the continental interior and reduced snow pack and shrinking glaciers; Source: An Open Letter to the Prime Minister of Canada on Climate Change Science April ; Signed by 90 Canadian climate science leaders from the academic, public and private sectors across the country Sea level rise: Fraser Valley scenarios

17 What do Canadian climate scientists say?
Threats to the sustainability of Canada’s natural resources due to an inability of our ecosystems to respond rapidly as the climate changes. Warming allowing the spread of insects through our forests and prolonged drought making forests more susceptible to fires; Warming of ocean and river waters, threatening survival of Pacific salmon, a cold water fish, by forcing it away from its spawning grounds; Source: An Open Letter to the Prime Minister of Canada on Climate Change Science April ; Signed by 90 Canadian climate science leaders from the academic, public and private sectors across the country Sea level rise: Fraser Valley scenarios

18 What do Canadian climate scientists say?
Increasing severity and frequency of some extreme weather events, including floods and droughts, some of which are already exceeding 100-year records and requiring more robust design specifications for infrastructure; Thawing of permafrost and associated effects on the human environment (infrastructure, roads, pipelines, buildings), sea ice, northern ecosystems and species, all leading to dramatic changes in the lives of northern people; Source: An Open Letter to the Prime Minister of Canada on Climate Change Science April ; Signed by 90 Canadian climate science leaders from the academic, public and private sectors across the country Sea level rise: Fraser Valley scenarios

19 What do Canadian climate scientists say?
Increased marine traffic through the northern sea routes, increasing the likelihood of environmental impacts and challenges to Canada’s sovereignty claims in the Arctic. Some of these projected impacts are already detectable.

25 A view from the US Dept of Energy
Of particular concern are nonlinear changes in the intensity, frequency, magnitude, or geographic locus of losses. As a real-world example, according to a letter published in Nature, the European heat wave of 2003 was six standard deviations from the norm. Rising uncertainty will confound pricing and reduce insurability in some cases. Evan Mills, a staff scientist at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory. Sea level rise: Fraser Valley scenarios

26 A view from the US Dept of Energy
From an actuarial perspective, abrupt climate change is much more of a challenge to insurers than a stylized view of gradual and linear changes over long time frames. Evan Mills, a staff scientist at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory. Sea level rise: Fraser Valley scenarios

27 A view from the US Dept of Energy
Insured losses from weather-related events in 2005 approached $80 billion (4 times those from 9/11), and that excludes a host of small-scale events that don’t appear in the official statistics. Evan Mills, a staff scientist at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory. Sea level rise: Fraser Valley scenarios

28 A view from the US Dept of Energy
It is important to note that many of the impacts of climate change, especially small-scale or gradual-loss events that have enormous aggregate costs—lightning, permafrost melt, mold, drought, or sea-level rise—are poorly (if at all) incorporated in these models. This creates some worrisome blind spots, which I’m afraid will grow larger under climate change.

33 Some thoughts on BC forests
“British Columbia hasn't been this warm in 8,000 years, and the winters are no longer cold enough to keep the beetles in check. Global-warming scenarios the International Panel on Climate Change forecast for 50 years from now are already unfolding in the province's interior.” Source: Globe and Mail, April 22, 2006; “We Might Become Extinct” by Terry Glavin Sea level rise: Fraser Valley scenarios

34 Some thoughts on BC forests
“Now, Dr. Hebda is starting to wonder whether the pine forests will ever grow back. ‘We just don't know,’ he says ‘Lodgepole-pine forests need catastrophic events such as beetle outbreaks and a few decades, even from a beetle outbreak even of this magnitude.’” Source: Globe and Mail, April 22, 2006; “We Might Become Extinct” by Terry Glavin Sea level rise: Fraser Valley scenarios

35 Nothing is "normal" any more.
“But nobody knows whether B.C.'s climate, decades from now, will be able to support pine forests. Nothing is "normal" any more.” Source: Globe and Mail, April 22, 2006; “We Might Become Extinct” by Terry Glavin Sea level rise: Fraser Valley scenarios

38 Will there even be any trees?
“’The question is, will there be forests at all in the southern portion of British Columbia's central interior? Will there even be any trees?’ Dr. Hebda asks. ‘It all depends on how much CO{-2} we push into the atmosphere.’” “So, when Dr. Hebda looks into the future, he sees a lot of sagebrush, grassland and rangeland where the pine forests are now, at high elevations, and down among the spruce, fir and ponderosa pine.” Source: Globe and Mail, April 22, 2006; “We Might Become Extinct” by Terry Glavin Sea level rise: Fraser Valley scenarios

39 Global Warming & Sea level rise
Climate Change: On the Edge Greenland Ice Cap Breaking Up at Twice the Rate It Was Five Years Ago by Jim Hansen, director of the NASA Goddard Institute for Space Studies in New York, is President George Bush's top climate modeller. Published on Friday, February 17, 2006, by the Independent/UK : Sea level rise: Fraser Valley scenarios

40 Global warming: Sea level rise
“How far can it go? The last time the world was three degrees warmer than today – which is what we expect later this century – sea levels were 25m higher. So that is what we can look forward to if we don't act soon.” Dr. James Hansen; Published on Friday, February 17, 2006, by the Independent/UK : Sea level rise: Fraser Valley scenarios

41 Sea level rise: Fraser Valley scenarios
Risk is increasing “ Thus, there is now perceived to be a greater risk that the upper end of the well known IPCC TAR estimate of a 1.4 to 5.8oC temperature rise will be reached or exceeded by 2100.” IPCC: Intergovernmental Panel on Climate Change TAR: Third Assessment Report Source: Stronger Evidence but New Challenges: Climate Change Science ;Will Steffen; Executive Director of the International Geosphere-Biosphere Programme (IGBP) from 1998 through mid-2004 and, since then, as IGBP Chief Scientist and as Director of the Centre for Resource and Environmental Studies, at the Australian National University.

44 Global warming: sea level rise
“None of the current climate and ice models predict this. But I prefer the evidence from the Earth's history and my own eyes. I think sea-level rise is going to be the big issue soon, more even than warming itself.” Dr. James Hansen; Published on Friday, February 17, 2006, by the Independent/UK : Sea level rise: Fraser Valley scenarios

45 Global warming: sea level rise
“It's hard to say what the world will be like if this happens. It would be another planet.” Dr. James Hansen; Published on Friday, February 17, 2006, by the Independent/UK : Sea level rise: Fraser Valley scenarios

46 Global warming: sea level rise
“How long have we got?” Dr. James Hansen; Published on Friday, February 17, 2006, by the Independent/UK : Sea level rise: Fraser Valley scenarios

47 Global warming: sea level rise
“We have to stabilize emissions of carbon dioxide within a decade, or temperatures will warm by more than one degree. That will be warmer than it has been for half a million years, and many things could become unstoppable. “ Dr. James Hansen; Published on Friday, February 17, 2006, by the Independent/UK : Sea level rise: Fraser Valley scenarios

48 Global warming: sea level rise
“This new satellite data is a remarkable advance. We are seeing for the first time the detailed behavior of the ice streams that are draining the Greenland ice sheet.” Dr. James Hansen; Published on Friday, February 17, 2006, by the Independent/UK : Sea level rise: Fraser Valley scenarios

49 Global warming: sea level rise
“They show that Greenland seems to be losing at least 200 cubic kilometers of ice a year. It is different from even two years ago, when people still said the ice sheet was in balance.” Dr. James Hansen; Published on Friday, February 17, 2006, by the Independent/UK : Sea level rise: Fraser Valley scenarios

51 Global warming: sea level rise
“Hundreds of cubic kilometers sounds like a lot of ice. But this is just the beginning. Once a sheet starts to disintegrate, it can reach a tipping point beyond which break-up is explosively rapid.” Dr. James Hansen; Published on Friday, February 17, 2006, by the Independent/UK : Sea level rise: Fraser Valley scenarios

52 Global warming: sea level rise
“The issue is how close we are getting to that tipping point. The summer of 2005 broke all records for melting in Greenland. So we may be on the edge.” Dr. James Hansen; Published on Friday, February 17, 2006, by the Independent/UK : Sea level rise: Fraser Valley scenarios

53 Global warming: sea level rise
“Our understanding of what is going on is very new. Today's forecasts of sea-level rise use climate models of the ice sheets that say they can only disintegrate over a thousand years or more.” Dr. James Hansen; Published on Friday, February 17, 2006, by the Independent/UK : Sea level rise: Fraser Valley scenarios

54 Global warming: sea level rise
“But we can now see that the models are almost worthless. They treat the ice sheets like a single block of ice that will slowly melt. But what is happening is much more dynamic.” Dr. James Hansen; Published on Friday, February 17, 2006, by the Independent/UK : Sea level rise: Fraser Valley scenarios

55 Global warming: sea level rise
“Once the ice starts to melt at the surface, it forms lakes that empty down crevasses to the bottom of the ice. You get rivers of water underneath the ice. And the ice slides towards the ocean.” Dr. James Hansen; Published on Friday, February 17, 2006, by the Independent/UK : Sea level rise: Fraser Valley scenarios

56 Global Temperature and Sea Level
Sea level rise: Fraser Valley scenarios

57 Global warming: sea level rise
“Our NASA scientists have measured this in Greenland. And once these ice streams start moving, their influence stretches right to the interior of the ice sheet. Building an ice sheet takes a long time, because it is limited by snowfall. But destroying it can be explosively rapid.” Dr. James Hansen; Published on Friday, February 17, 2006, by the Independent/UK : Sea level rise: Fraser Valley scenarios

58 Global warming & sea level rise Others agree
“But if one is interested in risks and in preparing to meet them, the more interesting question is what the deep historical record can tell us about the circumstances under which climates have changed rapidly in the past and the severity of the consequences. Considered in that way, accelerated glacial melting and larger changes in sea level (for example) should be looked at as probable events, not as hypothetical possibilities.” Source: Editorial, Science, VOL MARCH 2006 Sea level rise: Fraser Valley scenarios

We fly, We kill “It’s not just that aviation represents the world’s fastest growing source of carbon dioxide emissions. The burning of aircraft fuel has a “radiative forcing ratio” of around 2.7(11).” By George Monbiot. Published in the Guardian 28th February 2006 Sea level rise: Fraser Valley scenarios

74 Sea level rise: Fraser Valley scenarios
We fly, We kill “What this means is that the total warming effect of aircraft emissions is 2.7 times as great as the effect of the carbon dioxide alone. The water vapour they produce forms ice crystals in the upper troposphere (vapour trails and cirrus clouds) which trap the earth’s heat.” By George Monbiot. Published in the Guardian 28th February 2006 Sea level rise: Fraser Valley scenarios

75 Sea level rise: Fraser Valley scenarios
We fly, We kill “According to calculations by the Tyndall Centre for Climate Change Research, if you added the two effects together (it urges some caution as they are not directly comparable), aviation’s emissions alone would exceed the government’s target for the country’s entire output of greenhouse gases in 2050 by around 134%(12).” By George Monbiot.
