The effects of human-caused global warming are happening now, are irreversible for people alive today, and will worsen as long as humans add greenhouse gases to the atmosphere. FYI Recycling doesn't work!
Young people are going to demand change and retire all the old farts slowing down progress and destroying the planet because of their greed. Burning fossil fuels, cutting down forests and farming livestock are increasingly influencing the climate and the earth's temperature. This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming. We have already crossed the tipping point in many respects for Climate Change. Sadly we could be hit with a climate one two punch unless we act quickly even though the "The Day After Tomorrow" film shows an exaggerated scenario, there have been historical tipping points after which the climate system reacted quite swiftly. "In the past it happened really, really quick," scientists say. "Like, within the span of a lifetime, everything has suddenly changed.
Those who work in aviation have noted (especially air traffic controllers) that, in some cases, have worked same radar facilities, or control towers their entire career. Aircraft perform best into the wind. This is a fundamental rule of aviation. For this reason, runway changes are implemented to always utilize the winds to the best advantage. Crosswinds and tailwinds are not ideal, you want to head into the wind. The tower controllers in many cases have said, you know, back in the 80s, we used the XYZ runway configs maybe, 3 or 4 times per year. In some cases, it's like the east/west flows, where 99% of the time they're in a north flow, or similar. But now they run east/west flows half of the time when operating...it's like, how can this be? Have the winds truly changed THAT much in just 20 years? The answer is yes. When you hear anecdotes from everyday people like this, it really hits you, even more than the charts and hard science/data.
The cold blob in the North Atlantic (also called the North Atlantic warming hole) describes a cold temperature anomaly of ocean surface waters, affecting and weakening the Atlantic Meridional Overturning Circulation (AMOC) which is part of the thermohaline circulation, this is the theme of the film the Day After Tomorrow! It is changes in the salt content and temperature of the oceans. Scientists believe a vast amount of fresh water from melting glaciers especially from Greenland poured into the Atlantic, interfering with the conveyor belt. Fresh water is lighter than salt water and can inhibit the sinking motion that powers the entire current. Seas are predicted to rise a foot by 2050, regardless of how much global carbon emissions can be reduced. The halt of AMOC would create three feet of sea rise in NYC and the loss of All major coastal cities in Europe by 2050! Maybe some of us would rather ignore the science what is clear is that the most vulnerable the elderly and children under five will be the least likely to survive this.
Overall, tens of millions of people around the world live where a 3-foot rise in sea levels would submerge their homes. This will lead to the flooding of vast and densely populated areas. Some island states of Oceania may disappear entirely. If sea levels rise by one meter in Europe, conservatively some 33 million people in existing or potential flood zones could be forced to leave their homes. Today, one in five Europeans is 65 years or older. By 2050, it will be close to 30 per cent. The rapid population ageing Europe is experiencing is a seminal demographic shift that is affecting virtually all spheres of society. Who is prepared to take in these elderly climate refugees who consistently have opposed letting non Europeans into their spaces?
Amid news of lethal heatwaves across the Northern Hemisphere comes the daunting prospect of a climate disaster on an altogether grander scale. New findings published in Nature Communications suggest the Atlantic meridional overturning circulation, or AMOC, could collapse within the next few decades – maybe even within the next few years – driving European weather to even greater extremes. If the Amoc collapses we can expect larger extremes of heat, cold, drought and flooding, a range of “surprises” to exacerbate the current climate emergency. The potential climate impacts – on Europe in particular – should add urgency to our decision-making. That however is unlikely as Europe's leaders fear the loss of profits more than human lives thus they make their own future in doubt.
Research shows that it is in fact. man made global warming that is the real threat to humanities existence. IPCC makes it clear every year that if we keep ignoring what nature is telling us, mother earth is going to get rid of us and rightfully so if we continue these self destructive behaviors and trust greedy fools to lead us. What is apparent is that earth will survive but not necessarily humans.
Of all species on the planet humans may be the least intelligent! So will we be stupid enough to cause our own extinction? Probably, yes if we expect our leaders perspectives to change without being forced to...the only question is will it be in time?
Without worms, beetles and other animal detrivores it would be difficult, if not impossible to maintain soil condition to grow crops. In addition, hand pollination is laborious and unfeasible on large scales. Wild forests and grasslands would die because they are adapted to rely on animal decomposers as well as pollinators and seed dispersers. This would cause abrupt loss of rainfall, atmospheric change and climate change. Widespread starvation combined with lack of decomposition would cause rampant disease. States would collapse into warring tribes with no capacity to develop the technology to counter these issues.
That is, assuming the extinction is sudden. If it happened slowly enough, and people were aware that it was happening and prepared for it, we could perhaps manage to preserve some pockets of humanity. But, given our apathy about the fact that we're already causing a mass extinction that's expected to wipe out 30-50% of species in the next century, I doubt we would even try.
