The Warm Planet
Global warming as an earthbound process has been occurring for at least six decades, and it has been measured now for almost five decades. The evidence and trendlines are unmistakable and ultimately undeniable, though many in the world today, even yet, seek to propagandize the truth and to publish misinformation in denial of global realities. We have rising sea levels inundating islands across the Pacific and Indian oceans. We have the few remaining glaciers retreating at unprecedented rates worldwide. We have Polar Ice Caps not a fraction of their size and depth of even a decade previously. We have a disturbed hydrological cycle, with increasing amounts of water vapor entering the Earth's Atmosphere, like the high humidity of a hot green house, and precipitating out in monster storms and unseasonal flooding. We really do not need to have to count to four once we get past three to see where the sequence of number facts are heading--and we don't have to be told by Big Brother, whether in the guise of a Born Again Evangelical or a Muslim Warrior of God, that two and two make three, not four.
But what we do not trully know, and cannot clearly predict, is where this trend of global warming is taking us and what are the long term consequences of such a trend. The world has been warm before. Undoubtedly, during much of the Permian and Triassic and Jurassic, the world was probably on average much warmer than it has been in our own geological epoch that has been characterized by the recurrence of periodic Ice Ages. A warm world is a world with elevated sea levels and submerged coastlines and lowlands. It is a world of inland seas and huge monster storms. It is perhaps a world in which life its grows to gargantuan proportions, fueled by the tropical growth of canopys that reach higher and higher for the sky.
We cannot know the long term outcomes of such basic change processes, but we will certainly have to adapt and adjust ourselves to whatever outcomes we are dealt. We have never learned to control the climates and weather of the world, we have only learned to protect ourselves in our architectural constructions from that weather and climate. Certainly, whatever the consequences of global warming, we will have to learn to live without the luxuries of white Christmases and Fall colors.
Certainly Mount Everest will never be inundated in a Water World, nor even the Sierra Madre in California nor the Andes, nor even the foothills of Salinas. And change is fundamental to natural systems--it is inexorable. But human beings, and human civilization, have the unprecedented luxury of being able, ultimately, possibly, to change themselves, and to seek to control, in albeit constrained and however limited ways, the changes that they cause in the natural world they inhabit.
