In Ukraine, scientists of Central Geophysical Observatory (Kiev) have found a unique air temperature extremes, the maximum of which was registered on 17 July + 35,4 ° C. And in four days, this record has dropped to its lowest level in 136 years of observations +18,2 ° C.
Scientists also point out that the cold snap at the beginning of the third decade of July was interrupted by a unique series of 90 temperature records, which began December 20, 2014.
The average monthly temperature in July was 22,4 ° C, which exceeded the climate norm by 3,1°C. Coldest was on July 8, when the temperature in the morning dropped to + 12,7 ° C. What are the reasons of the unique extremes of air temperature in July 2016
It may the cause of deforestation, loss of forest cover and increased settlement. If the same temperature you record in forest area of the place it may be different. Global temperature increases do not reflect the sign of climate change in particular place. Increasing Global tem is the another part of impacts like hydrological cycle, fluctuation of seasonal rainfall pattern, change in precipitation, snow/glacier melting. The drought effect may be reach your question due to climate change but it also depends ecosystem in the particular place. So need for more measurement and record for further justification.
Thanks
Zenon, those extreme changes happen more frequently today, and not only in Ukraine. For example, in Vienna on August 12, 2015 there was +34, while in a few days (19/8) a local minimum of +19 has been observed. Since that did not happen so often in the past, I guess that global climate change might be a potential reason.
But what is more frequent is chaotic sequence of weeks in spring, when a typical temperature for May (too hot) might occur in March, and then cold week with typical March’s temperature for this location might come in May. Before it was more continuous, and now even an average month’s temperature might not grow between 2 months in spring in some locations.
So nice question!
Dear Zenon,
I advise you to do a scientific survey about temperature rising all over the world to get a clear idea about temp. levels. For example in the south of Iraq, in Basrah the temp. reached upto 51 degrees centigrade. I think, that happened due to many reasons such as, no new green lands, no limitation in waste gases emission, and other!

Dear Zenon:
One of the reasons for recent extreme temperature measurements is that we did not have the technology to measure and record such extremes previously. Even 50 years ago, we had minimal measurements or records. But 100+ years ago, we had virtually nothing. With the advent of the internet; inexpensive and accurate temperature & weather measurements; and primarily satellite weather measurements, we are beginning to see extremes that most likely have always existed. World wide satellite weather monitoring is a 25-30 year old technology. Its is difficult to compare how bad the extremes are this year with other years when we only have a short period to compare to. The ice age ended 13,000 years ago - and our record of 25-30 years is insignificant in comparison.
Regards,
John
This is a great question that is on the minds of many. I recently went back and looked at the causes of past extinction periods; there are five. Each case shared similar contributors like flood basalt eruptions, sea level fluctuations, methane gas release, declines in marine and land life, and the external factor, asteroid impacts. We all know that sea levels are changing and life on our planet has entered a decline, but whats even more alarming is the increased volcanism and seismic activity (outside of fracking), and most recently these methane bursts both on the oceanic floor and on land. One such case happen in the southwest the other day. These are telltale signs of a changing climate. What's interesting is the human contribution to it all, which is still relatively unknown since we also don't know how much it takes to create an unstable situation on Earth, and we don't know the relationship between that and how it impacts the Earth underneath the surface. There are several questions we should be asking ourselves next like how much are we contributing to the temperature increase? What type of internal pressure build-up do we have underneath the surface, and is that related somehow to what we have done over the several centuries? Is there a positive feedback in that our influence is initiating a possible pressure build-up associated with volcanism and methane release that would then increase the temperature even further?
What are the reasons of the unique extremes of air temperature in July 2016 ?
I suggest having a look at both ENSO Below is a link for ENSO.
http://www.bom.gov.au/climate/enso/indices.shtml
You can also check the RSS and UAH satellite records for teleconnections via the atmosphere.
In my opinion, you should also check out the AMO and the NAO.
For such short-term fluctuations, I would be looking for the interplay between the polar vortex, ENSO, and both the AMO and NAO.
