Why has Earth’s climate changed so radically in such a short span of time? The elephant in the living room is combustion heat from fossil fuels and wood pellets chopped up from old-growth forests. That accumulated heat is being stored deep within the oceans. Over the previous 25 years, that heat is the equivalent of dropping 3.6 billion Hiroshima atom-bombs. The oceans drive Earth’s climate, which has become unstable with both higher highs and lower lows.
Even to the untrained eye, the effects of climate instability are highly conspicuous across western North America’s cold tolerant and hardy coniferous forests.
