Have you been noticing any strange weather lately?
Well, don't let the naysayers fool you. You're not alone.
The Earths current weather patterns are in a state of disarray right now.
The Jet-streams are frequently becoming locked. Causing storm systems, temperatures, and other extremes to remain stuck in one place for extended
periods of time. A rare second jet-stream also remains situated over the Arctic, which is uncommon during the warmer months. Typically, there is only
one jet-stream in the Northern-Hemisphere during the summer. Meanders in the flow of these streams are reeking havoc on the climate, melting sea-ice,
and contributing to various weather anomalies across the globe.
These shifts in winds not only affect weather patterns throughout the Arctic but are also thought to influence weather in Greenland, the United
States, and western Europe. Understanding such links is an ongoing area of research, the scientists said. The effects of Arctic amplification will
increase as more summer ice retreats over coming decades. Enhanced warming of the Arctic affects the jet stream by slowing its west-to-east winds and
by promoting larger north-south meanders in the flow. Predicting those meanders and where the weather associated with them will be located in any
given year, however, remains a challenge.
“What we're seeing is stark evidence that the gradual temperature increase is not the important story related to climate change; it's the rapid
regional changes and increased frequency of extreme weather that global warming is causing. As the Arctic warms at twice the global rate, we expect an
increased probability of extreme weather events across the temperate latitudes of the northern hemisphere, where billions of people live,” said
Jennifer Francis, Ph.D, of Rutgers.
A phenomenon known as Atmospheric Blocking
- is just one of the many effects Climate
Change will have on the near future, and it has been on the rise over the past decade.
A study done by NASA in 2011, looked at data from the 20th century and concluded that Blocking events were not only on the rise, but they were more
likely to happen during periods when ocean temperatures were warmer than usual. Researchers found that between the years (1990-present day), these
events occurred up to 30% more often than in other years; Especially after the year 2000.

discusses the current rate at which deep-sea ocean temperatures are rising:
and as described above, may have an effect on the jet-stream.
Deep oceans warming at an alarming rate
signals from warming ocean surface waters, a new re-analysis of data from the depths suggests dramatic warming of the deep sea is under way -
The scientists report that the deep seas are taking in more heat than expected, which is taking some of the warming off the Earth’s surface, but it
will not do so forever.
The bottom line, says Trenberth, is that the heat of global warming is going to different places. “So global warming is continuing even though
it’s not always manifested as a strong surface temperature increase. It’s just manifesting itself in different
But that's not all that links these strange occurrences together.
The Sun is responsible for the majority of weather conditions all over the planet, and it is currently experiencing an 'unexpected' low-point in solar
activity. You might already be aware of the lack of solar flares and/or sunspots, during what was suppose to be a solar-maximum this year, 2013:
'something unexpected is happening to the Sun'
(Released on March 8th.)
'Something unexpected' is happening on the Sun, NASA has warned.
This year was supposed to be the year of 'solar maximum,' the peak of the 11-year sunspot cycle. But solar activity is relatively low.
And this article, (7/12/13)
Sun's bizarre behavior: Weakest solar
cycle in 100 years
2013 was supposed to be the year of solar maximum -- the peak of an 11-year cycle when the number of sunspots that mar the
sun's surface is at its highest. But scientists say our current solar maximum, known as solar maximum 24, is the weakest one in 100
Conflicting studies suggests, low solar-activity may also have an effect on the Earths Jet-stream; causing out of the ordinary weather patterns.
Especially during the colder months in western Europe. Low solar activity can lead to Atmospheric Blocking and prevent warmer westerly winds from
entering the region:
Solar Activity Changes Regional Jetstream Flows
Low solar activity link to cold UK winters
The research finds that low solar activity promotes the formation of giant kinks in the jet stream. These kinks can block warm westerly
winds from reaching Europe, while allowing in winds from Arctic Siberia. When this happens in winter, northern Europe freezes, even though other,
comparable regions of the globe may be experiencing unusually mild
The UK and continental Europe could be gripped by
more frequent cold winters in the future as a result of low solar activity, say researchers.
The researchers used the 351-year CET record because it provided data that went back to the beginning of the last Maunder Minimum, a prolonged period
of very low activity on the Sun that lasted about half a century.
The Maunder Minimum occurred in the latter half of the 17th Century - a period when Europe experienced a series of harsh winters, which has been
dubbed by some as the Little Ice Age. Following this, there was a gradual increase in solar activity that lasted 300 years.
If we take all of this information and put it together, a clearer picture begins to emerge...
The effects of Climate Change will continue to alter Earths weather. Regardless if you want to admit it or not; it's already happening. It's happening
in many different ways, for many different reasons, and it's happening faster. The signs are becoming more and more prevalent, and even the slightest
changes in the Earth are capable of much more than people really understand.
There is a plethora of evidence out there, and if you look hard enough you can piece most of it together. Adjustments should be made to prepare for
it; rather than debate whether or not humans are the cause. The full extent and outcome of these changes remain uncertain. But it's better to know;
than to not know, I suppose.
(well, you be the judge.)
