#Methane releases in the #arctic
Incredible sea surface temperatures (SST) in the east siberian arctic shelf (ESAS) , other arctic seas
This is an analysis of the latest scientific study published by Dr Shakhova, analysed by "just have a think" .
It will give you a quick insight of the available knowledge on the topic

This is a 7 year old video from doctor Shakhova, warming of potential problems.
Warming seas, warming sea bed , no ice coverage, destabilizing methane clathrates.
Sounds familiar?

#MeltingPoles: Unprecedented Arctic Heat Leads to Second Lowest Sea Ice Minimum this Year

weather.com/en-IN/india/en…

(📸: @NASA's Scientific Visualization Studio) Image
#GlobalWarming is regarded to be the primary reason behind the increasing melting of ice sheets over the two polar regions of the Earth.
This year, however, the warming over the north polar region witnessed a new high with some parts recording up to 10°C warmer than normal temperatures.

The #Arctic #seaice loss of summer 2020 has made headlines, but we shouldn’t forget the winter🧊loss
In February 2018 & 2019, the extent of sea ice in Bering Sea was 60-70% lower than the average, due to #climatechange

Study Estimates Global Ice Loss of 28 Gigatonnes Since 1994; #Arctic Worst-Hit - by @MrigDixit

weather.com/en-IN/india/en…

(Image credit: NASA/Joe MacGregor) Image
Melting and refreezing of ice around the globe is an annual natural phenomenon, but owing to the gradual rise in global average temperature, the cycle is no longer marked by just the seasonal variability.

#ClimateChange
Over the last few decades, the accelerated irreversible melting has been a prime indicator of #globalwarming and is posing a massive threat to the entire world in the form of rising sea-levels.

Earth has lost a 'staggering' 28 trillion tonnes of ice to global warming in the last 23 years, UK scientists find

businessinsider.in/science/news/e… Image
A "staggering" 28 trillion tonnes of ice has disappeared from the surface of the #Earth since 1994, a group of UK scientists has found.
Scientists from #Leeds and #Edinburgh universities and University College London analyzed satellite surveys of glaciers, mountains, and ice sheets between 1994 and 2017 to identify the impact of global warming.

.@NASA confirms that the dent in #Earth’s protective shield is splitting into two as it gets bigger - by @pabsgill

businessinsider.in/science/space/…
The bigger the anomaly gets the wider its sphere of influence. A weak magnetic field means that the particle radiation from the #Sun gets closer to the #Earth’s surface than otherwise.
In addition to messing with compasses and throwing bird navigation off, this means it can also knock out onboard computers and interfere with satellites on their rounds to collect data.

New precedent in scale & intensity of #Siberia/#Arctic #wildfires compared to previous 17 years in the #Copernicus Atmosphere Monitoring Service GFAS data based on MODIS obs confluence.ecmwf.int/display/CKB/CA… (145 Mt CO2 in July 2020 vs. 182 Mt CO2 total for 2019) #ArcticFires ImageImageImage
Daily cumulative estimated #ArcticCircle #wildfire carbon emissions for 2020 (red) were already increasing faster than in 2019 (gold) but increased significantly in the 2nd half of July Image
Comparing the annual total estimated #wildfire CO2 emissions for the #ArcticCircle from 2003 to 2020 (up to 31 July 2020) shows that this year is already the highest for the region in the GFAS dataset. Image

#Pompeo 🇩🇰 meeting readout (Arctic inc): Danish Min Kofod outlines pragmatic approach to 'deterrence' & dialogue wrt 🇷🇺 "we will ensure that we have the proper capabilities in the region, & we want to maintain close cooperation based on Arctic Council & the Ilulissat Declaration"
Min Kofad did not frame #Arctic concerns related to China, which was interesting. both "signed new MoUs...that cover a wide range of areas, like growing Greenland’s mining and energy sectors through transparent investment, helping manage land and fisheries" ....transparency...
press q's: agenda to "round up support among allies against China...all due respect, why on Earth...Denmark, of all places?" In the Arctic, China has fancied themselves as a near-Arctic nation. We have a responsibility to get that right for...our own sovereign security issues"

Historic “blue ocean event” for the #Siberian side of the Arctic?

I wanted to summarize and clarify a exchange between @ZLabe and myself related to a potential for a “blue ocean event” BOE or ice-free condition for the Siberian side of the #Arctic by the September low. 1/7
The #Arctic ocean is divided large regions as indicated on the map on the right. Zack combines sea ice data from three of these regions; region 3, 4 and 5,which are the East Siberian, the Laptev and Kara Sea respectively. The result is the chart on the right. 2/7
The individual charts look like this: 3/7

U.S #Arctic fun: 1. Issues outlined miss prob only disagreement bw A5 states - 🇺🇸 🇨🇦 maritime challenge 2. technically it’s a process of ‘remilitarisation’ on account of the Cold War 3. lumping 🇨🇳 🇷🇺 into same axis in Arctic is problematic - geography/history makes one legitimate
4. 🇺🇸 is extremely active & engaged in Arctic gov structures & WGs - not sure how a consulate here will bolster any real power. “Facility” 👀 this expensive office block will work to interrupt sig advances 🇨🇳 has made into 🇬🇱 economy, gov/industry & precious minerals sectors.
expect 🇬🇱 to be tabled with a pick your side decision wrt any further 🇨🇳 investment. 🇷🇺 will envy the geostragtic position a 🇺🇸 outpost in 🇬🇱 affords. no doubt seige mentality/ encirclement fears will be fanned in Moscow.
