Global warming is one of the issues that human civilization will have to deal with during "The Great Tribulation". There is already awareness of the issue among scientists, as well as the potential implications of climate change on the food supply and arable land.
Global warming and climate change were not an issue the last time we were in a Grand Supercycle degree bear market, even during 1770 - 1784 (Supercycle wave (c) of Grand Supercycle wave [II]). It is an issue that we will be facing in the future as a consequence of the excessive use of fossil fuels such as petroleum, coal, and natural gas. The burning of fossil fuels results in the release of carbon dioxide in the atmosphere, increasing the greenhouse effect in the atmosphere and resulting in global warming.
There has been many warnings from scientists about the implications of staying the course on excessive use of fossil fuels. Even Hollywood has gotten into the fray as well with the release of The Day After Tomorrow in 2004, which imagines destructive weather of unprecedented magnitude unfolding as a result of climate change. Yet, the warnings continue to be ignored by many people and even the Obama Administration didn't make an effort to address the issue when there was an opportunity to do so with a large majority in the House and a filibuster proof majority in the Senate in 2009. Human civilization will end up learning the importance of clean energy the hard way in the coming years and decades, especially in the United States.
The implications of global warming has been examined by a number of scientists, such as the article Memorial Day 2030 from Climate Progress. The timing will be affected by an emerging "green technology" industry that will start to take hold after "The Great Deflation" ends, giving rise to the "Green Technology Age" (identified as Supercycle wave (b) of Grand Supercycle wave [IV]) which will start in 2021 and end in 2042. The rise of a green technology industry will slow down the rate that greenhouse gases are accumulated in the atmosphere, which will ultimately affect the timing of when the effects of climate change will start having a substantial impact on human civilization.
It will be around 30 years or so before climate change will have a substantial impact on human civilization. We are starting to see some hints of the effects of climate change in the future. Just this year, we got some of the most extreme weather in many decades take place, with the 2011 Mississippi River floods, the 2011 Super Outbreak (of tornadoes), and most recently, the 2011 Joplin tornado.
Given the negative social mood that will be present during "The Great Tribulation", food shortages and increasing scarcity of arable land, both caused by climate change, could easily be used as a justification for starting a war. Wars generally erupt during the largest C waves of bear markets of Primary degree and above, and history (going all the way back to 1200 BC) indicates that Grand Supercycle degree bear markets always result in war. The period of "The Great Tribulation", identified as Supercycle wave (c) of Grand Supercycle wave [IV], would be a time when wars over resources would erupt.
There is a lot of skepticism about global warming and climate change now, but I predict that a "point of recognition" will take place in 2043, which will take the form of a "Global warming panic". This would be the center of Cycle wave I down during "The Great Tribulation". At that time, it will be impossible for people to dismiss the reality of man made global warming due to the impact of extreme weather that will be unfolding during that time.
Look for governments to make some very hard choices about the use of fossil fuels and the use of green technology during the first few years of the next bull market, Grand Supercycle wave [V]. The effects of climate change will remain well after "The Great Tribulation" ends, but with the hard choices that governments will make during 2055 - 2058, the planet's climate will slowly return to normal over many decades during the bull market that will unfold.
