where is the ice Alaska is warming up

Alaska is warming fast: record negative ice floes and warming temperatures have managed to confuse even the local climate measuring station, making it think it has been moved to a warmer climate

When you think of Alaska, the first images that come to mind are snow, ice, a puffy coat and thick clothing. But like the rest of the world, climate change is also affecting Alaska, which is getting warmer, and it turns out that in the Arctic region - to which Alaska is located - it is happening much more dramatically than the global average: last year, a report by the American Oceanic and Atmospheric Agency (NOAA) revealed thatThe North Pole is warming twice as fast as the world average. In fact, the change in the polar region is so significant that researchers He found out at the beginning of the month that the warmer than normal climate caused the climate research and measurement station stationed in Utkiagwick in northern Alaska to mistakenly think that it had been moved from its location to a warmer area.

Climatic measurement and research stations are scattered in various places all over the world, and they help scientists to document and monitor climate change as well as make predictions for the future based on the existing data. Alaska, which by nature is close to the North Pole and is mostly frozen and surrounded by floating sea ice for a large part of the year, is a relatively sensitive point to the effects of climate change - therefore the measurements there are very important and significant for the global database.

Measurements show that in recent decades the temperature in the American peninsula has been getting warmer, while the floating ice sheets - which reach it from the North Pole at the end of summer - have also begun to diminish and appear on its shores later and more in the year. While in the past the northern part of Alaska was surrounded by floating ice surfaces as early as October-November, in recent years it has been happening slower and later - until on November 19 this year the amount of floating ice in the area reached to a negative record of the last 40 years in which measurements were made in the area.

Heat stroke for the measuring station

The late and diminishing appearance of the ice is problematic not only because it changes the texture of life in the region, but mainly because it causes accelerated warming and helps increase the effect of climate change. This happens because the white ice absorbs very little of the solar radiation that reaches it, and when the sea or land is covered with ice, most of the solar energy that reaches them is returned to space. When the surface is darker - as in the case of bare land or the surface of the sea, more solar energy is absorbed by them, increasing the warming of the earth. The diminishing ice in Alaska, its late arrival and the fact that it covers the surface of the water surrounding it for fewer months of the year causes a feedback effect - according to which the less ice there is, the more and faster warming occurs, which in turn further delays the formation of ice or melts the existing ice.

The negative record recorded this year in floating ice, combined with the higher-than-normal temperatures, caused the activation of a mechanism designed for cases in which the local measuring station detects that an artificial change has been made around it - for example in cases where there is an internal fault in the system that could disrupt the veracity of the report, or when it is moved from its place to an area where Weather conditions other than the range to which she is accustomed. In such a case, a special algorithm causes the system to stop the automatic reporting of data - so as not to transmit false data to the system and disrupt the results of the measurements.

The researchers realized what happened when on December 4th - like every 4th of the month - they went to read and analyze the data, and discovered that during the month the system stopped automatically reporting the climate data - that is, it simply decided to disqualify itself due to excessive heat.

When you look at the data and realize that the temperature measurements in the region show that the average October of the 21st century is almost 8 degrees Celsius warmer than the month of October in the 1920s, you can understand the dimensions of the enormous change that is taking place in this region. In recent years Negative records are repeatedly broken In Alaska, the floating ice in the summer, the ice that accumulates on the mountain tops in the winter and the temperatures that quickly warm up. A combination of all these factors will undoubtedly lead for a global rise at sea level and harming the animals in an area that depends on the ice for their survival.

So when you fantasize about the dream cruise you'll take one day to Alaska - maybe instead of imagining the puffy coat, the hot woolen hat and the boots you'll be equipped with, you should think about a pair of good walking sandals, a short shirt and a hat against the sun's radiation.

    ..."Injuring a certain nation brought peace?" - Did I say it will bring peace?

    I said: "Injuring Muslims in general will lead to a decrease in the level of violence of Muslims towards all non-Muslims."

    Please, do not confuse others' minds with things that are not true, when you mention something from my words.

  2. Nostradamus
    You have a very serious mistake. You are mixing up the old schedule of tens and hundreds of thousands of years, with a modern schedule of several decades.

    Everything you say about life adapting to the environment is true, but it won't solve the problems of climate change. The Russians in the past tried to play with environmental changes and did irreversible damage. The Aral Sea was once the fourth largest lake in the world. The Sea This sea lake is called the "Aralkam Desert", if you didn't understand the context.

    Those who grow the most food today are the USA, Canada and Australia. The Elbian countries have been hit hardest in the last 50 years. I'm sorry to tell you - but this is not a topic for discussion. If you think corrupt Russia can feed the world then you are going to be surprised.

    The situation is very difficult. It's a shame you let your political views blind you. Go kill some Arabs if it makes you happy, but please, but destroy my children's world.

  3. Because it's a controversial, complicated subject and it's my personal opinion, those who want will agree and those who don't won't, of course everyone will watch in the end, compared to the rest which is scientific facts.
    The new territories that are currently frozen and uninhabitable will become the most fertile in the world and people will want to move there voluntarily because of the abundance. It is a fact that Russia is secretly very happy about the warming and rightly so. One area will become unlivable another much larger area will become a paradise. Human migration has always been and climatic changes too, once the Sahara desert and Antarctica were rainforest. Nothing is permanent, not in geology, not in climate, not in life. Man will adapt himself to nature and not the other way around...

  4. Nostradamus
    Why leave? This is exactly your problem - you have extreme right-wing views and it shows in your every response. Everything you say is colored by these opinions.

    Regarding agricultural areas, you are wrong. First of all, people don't live in these areas. So we didn't solve anything. I already told you - there is enough food in the world today, yet many are dying of hunger even today.

  5. Algae love heat and light and will thrive more than ever. The Japanese deliberately grow algae near Eilat because of the heat and intense light. Do an experiment at home...

  6. You didn't understand, I didn't mean that carbon dioxide will lead to an increase in vegetation. Although this is also true because it is part of photosynthesis. I meant that when Antarctica warms it will become a huge green continent, as well as Siberia, Northern Canada... that will produce more oxygen. In the past it was much warmer and in fact there was more oxygen and thanks to it there were bigger land animals than ever before. Even the parts of the oceans that are currently frozen will receive sunlight and algae will grow there.

  7. If I start getting into the topic I won't finish for a long time. In short, the source of evil comes from the Middle East.
    In any case, this is exactly what you are sticking to, leave politics at the moment. As far as humanity is concerned, the warming is an opportunity for flourishing if they use it wisely

  8. Nostradamus
    How did you conclude that the amount of vegetation will increase? The idea that it will increase in the amount of vegetation is not correct.

    And much worse than that - most of our oxygen is supplied by algae in the sea, and they are a very high danger due to the increase in temperature.

  9. Nostradamus
    Do the Muslims in Indonesia or Malaysia love the West? What about the Muslims who live in the USA, Germany, Australia, Denmark, France and Israel? Are they milder?

    Do you really think that killing is a justified way to prevent killing? 🙂

  10. Miracles!

    You say that Nostradamus is wrong and present to all of us your claims, which turn out to reinforce Nostradamus' words...

    In any case, regarding your second question, the answer is: "Yes".

    Harming Muslims in general will lead to a decrease in the level of violence of Muslims towards all non-Muslims.

    The problem is that it is not realistic. Therefore, other solutions are sought. Like talking to them... but they're on their own... Kapish?

  11. Indeed, in my opinion when the Arabs do not have nation states they will become more moderate and it will be easier to reform their religion. The meaning is that every destruction gives rise to new opportunities, just as a forest fire renews it. The increase in the amount of plants will increase the amount of oxygen and with them the biological diversity, the plants will absorb more carbon dioxide which will lead to cooling over time, if life thrived in a hot world in the past it will also thrive now. Sometimes you have to get rid of the old to make room for a better new one like a reset or format

  12. Nostradamus
    The matter of the amount of oxygen is not related.
    When there was a tropical climate in Antarctica there were no humans, how does that relate?
    No humans live in these vast areas today, and in contrast, hundreds of millions live in fertile places. Already today people are dying of hunger, and especially due to lack of water, even though there is enough in the world for everyone.

    Do you think harming Muslims in general will reduce their violence?

  13. So treat comments to the point. Because whoever curses personally and accuses of insanity (characteristic of debates with leftists) has already lost the debate. Which of the facts I mentioned did you not understand?

  14. Miracles
    It's okay... the Jews knew how to assimilate in Europe and the USA as well... just look in the mirror.

  15. Miracles. He is not the only Jewish barbarian... I, along with the vast majority of Israelis, is a barbarian Jew...
    And Islam is the religion of peace
    ??

  16. It's not bad. Once upon a time there was a tropical climate in Antarctica as well and through no fault of man and the amount of oxygen was 50% higher and life, animals and plants thrived and the number of species exceeded the amount today. In Alaska, Antarctica, Canada, Greenland and Russia, vast areas will become fertile and inhabitable and the Middle East and North Africa will burn in the heat together with barbaric Islam
