    2018 British Columbia wildfires | Google Crisis Map


    [​IMG]

    Map shows where 566 wildfires are burning in British Columbia as state of emergency declared

    As has been predicted, the increasing warmth, and the drying of the forests has created a perfect environment for large and numerous forest fires. Today, we are seeing that in spades in California, Oregon, Washington, and British Columbia.

    Climate Change in BC Dave Daust Historic climate Fifteen thousand years ago, most of BC was covered in ice. The ice melted between thirteen and ten thousand years ago after which the climate became warm, initially drier and then moister. About 4,500 years ago, BC entered a cooler period. Over the last 1,000 years, the northern hemisphere followed a slow cooling trend until about 1900 when rapid warming began, corresponding with increased industrialization and land clearing (Figure 1). Within those general trends are warmer and cooler periods as shown by the red oscillations in the figure below. See Hebda (1995) and Spittlehouse (2008) for further detail.



    Figure 1. “Variation in the annual Northern Hemisphere temperature over the last 2000 years expressed as the difference between the annual values and the 1961–1990 average. The green line shows data from the instrumental record and the red line is a multiproxy reconstruction from tree rings, ice cores, and corals. The blue line is the low-frequency component with uncertainty. (Adapted from Moberg et al. 2005.)” Reproduced from Spittlehouse 2008 with permission.

    Climate varies over a range of temporal scales. Variation in Earth’s tilt and orbit around the sun influence variation over centuries and millennia (Milankovitch cycles - Wikipedia). Several climatic oscillations that operate on the scale of years to decades affect BC, including the El Niño Southern Oscillation, Pacific Decadal Oscillation, Pacific North American Pattern and Arctic Oscillation (Moore et al. 2010). Variation due to oscillations can exceed mean changes in climate variables over a century (Rodenhuis et al. 2009). For example, in southwestern BC, precipitation in La Niña/cool PDO years is 39% greater than in El Nino/warm PDO years (Kiffney et al. 2002).

    BC has become warmer over the last century. Northern and southern BC have warmed more than coastal BC and parts of central BC (Rodenhuis 2009). Annual minimum temperatures have warmed more than maximum temperatures—BC is becoming “less cold” rather than “warmer” (Rodenhuis 2009, Pike et al. 2008). All seasons have warmed, but winter has warmed the most. As a result of warming, seasons are changing. The frost-free period has lengthened by 21 days over the last half of the last century.

    Climate change? More like poor management and illegals playing with matches. It looks like liberal loons are trying to blame everything on global warming.

    Another ignoramus chimes in. 21 more frost free days. More bug kill. Longer dry spells, and more lightning storms. Yes, climate change is definately impacting our forests, and those of our good neighbor to the north, Canada. So you think that illegals started the fires in BC and the North Cascades? I think you are even more stupid than your posts indicate. A really stupid bigot by all indications.

    Don't like being disagreed with do you troll? It shows. But hey, we all know this climate change crap is all made up to extort more money from us.

    Meh

    It's just a bad drought season. Duh

    I encourage anybody to go look at any historical map of US drought over the past 100 years. Sometimes bad....sometimes nothing.....for years. This idea that the drought is connected to AGW is only embraced by the k00ks.

    And then again, if global warming is causing this, why isn't it burning everywhere?

    Speaking of Ignoramus's Old Crock is it...

    Your making false causation assessments that do not have facts to back them up. Even native Americans have tribal records from the 1600-1700's that have cyclical massive fires during dry times.

    Poor forest management is the real problem here pushed by enviro wackos... Had trees been harvested and the forest allowed to floor burn removing the under fuels a crown fire, like we are seeing today, would not be happening.

    Its because of left wing green freaks that we are seeing the problems today and why our forests are dying from beetles and other infestations that natural fires dealt with.

    566 wild fires burning in BC....OMG that`s "only" ~ 1100 short of the average number of wild fires for British Columbia.

    Looks like Momma Nature has a serious carbon footprint of her own.
