Many of my ramblings in the last month have been about the world’s weather. The weather is helped by these currents that travel the world in a regular pattern, the temperatures are key, but after a quick study over the last day I noticed a big change in temperatures, and something I thought I would share, as it is important to us all. Many don’t believe in “Global Warming” being man made, some suggest it is just the way the world works. Like the Sun for example, every 11 years, it flips from North to South, it happened in 2002, and it will happen in May this year.
For all we know the Earth has a cycle, but it may be that big a cycle in terms of time, recorder records about it are hard to read or tall tales, or fantasy, we really are to young as an advanced species to understand it all, we are still learning. We don’t know it all. We know our eyes produce water that keeps our eyes dry for example. We can prove this, there are things that are highly speculative however when you turn the coin around. And I did
Take the North Atlantic Current for example, it comes from Southern Africa (Well further afield) but we will start there, it comes up the eastern side of the Americas, then up to Europe. The temperatures in this current are what made Europe habitable, as without this heat from the current of heat, we would be like Northern Siberia or Northern Canada, as we are on the same Latitude as these two places
So look at the picture above, look at Europe and the northern tip of the USA you will see we almost on same Latitude, this hot current brings us the heat that stops us living in a world where Snow and ice is the order of the day.
Where I did notice a chance is this current is weakening. This started in the late 1999’s and has just got worse. The weather on Earth has changed, there is NO debate. So here are the scenarios ahead
If the climate system’s Achilles’ heel is the Conveyor, the Conveyor’s Achilles’ heel is the North Atlantic. An influx of fresh water into the North Atlantic’s surface could create a lid of more buoyant fresh water, lying atop denser, saltier water. This fresh water would effectively cap and insulate the surface of the North Atlantic, curtailing the ocean’s transfer of heat to the atmosphere.
An influx of fresh water would also dilute the North Atlantic’s salinity. At a critical but unknown threshold, when North Atlantic waters are no longer sufficiently salty and dense, they may stop sinking. An important force driving the Conveyor could quickly diminish, with climate impacts resulting within a decade.
In an important paper published in 2002 in Nature, oceanographers monitoring and analyzing conditions in the North Atlantic concluded that the North Atlantic has been freshening dramatically—continuously for the past 40 years but especially in the past decade.4 The new data show that since the mid-1960s, the sub polar seas feeding the North Atlantic have steadily and noticeably become less salty to depths of 1,000 to 4,000 meters. This is the largest and most dramatic oceanic change ever measured in the era of modern instruments.
At present the influx of fresher water has been distributed throughout the water column. But at some point, fresh water may begin to pile up at the surface of the North Atlantic. When that occurs, the Conveyor could slow down or cease operating.
Signs of a possible slowdown already exist. A 2001 report in Nature indicates that the flow of cold, dense water from the Norwegian and Greenland Seas into the North Atlantic has diminished by at least 20 percent since 1950.
What future climate scenarios should we consider?
The debate on global change has largely failed to factor in the inherently chaotic, sensitively balanced, and threshold-laden nature of Earth’s climate system and the increased likelihood of abrupt climate change. Our current speculations about future climate and its impacts have focused on the Intergovernmental Panel on Climate Change, which has forecast gradual global warming of 1.4° to 5.8° Celsius over the next century.
It is prudent to superimpose on this forecast the potential for abrupt climate change induced by thermohaline shutdown. Such a change could cool down selective areas of the globe by 3° to 5° Celsius, while simultaneously causing drought in many parts of the world. These climate changes would occur quickly, even as other regions continue to warm slowly. It is critical to consider the economic and political ramifications of this geographically selective climate change. Specifically, the region most affected by a shutdown—the countries bordering the North Atlantic—is also one of the worlds’s most developed.
The key component of this analysis is when a shutdown of the Conveyor occurs. Two scenarios are useful to contemplate:
Scenario 1: Conveyor slows down within next two decades.
Such a scenario could quickly and markedly cool the North Atlantic region, causing disruptions in global economic activity. These disruptions may be exacerbated because the climate changes occur in a direction opposite to what is commonly expected, and they occur at a pace that makes adaptation difficult. This would be catastrophic to our planet and way of life
Scenario 2: Conveyor slows down a century from now.
In such a scenario, cooling of the North Atlantic region may partially or totally offset the major effects of global warming in this region. Thus, the climate of the North Atlantic region may rapidly return to one that more resembles today’s—even as other parts of the world, particularly less-developed regions, experience the unmitigated brunt of global warming. If the Conveyor subsequently turns on again, the “deferred” warming may be delivered in a decade.
So theoretical at best by me, with a few scenarios built in also. I am NO expert, but I do keep an eye on world events, and from what this pretend expert can see, things don’t look great.
I posted this video; here it is again, it looks bad add this blog I did about Volcanoes and Earthquakes, give me your thoughts below, the blog below is on weather, but mainly volcanoes and earthquakes, what is waking them up? We must find an answer
