The world is in this hot summer

  Hot hot hot hot! High temperatures swept the northern hemisphere this summer.
  Although the heat wave and its secondary damage are heard every summer, this year’s sweltering heat seems to be a little different: when walking on the road, even if you are mentally prepared, you can still clearly feel the inescapable scorching. ;Swipe your phone, the wording about “the high temperature once in decades” is full of words…
  Due to factors such as geographical location and coping habits, the extreme heat that most Chinese feel may be just “a piece of cake”. For some European and American countries and island countries, this year’s long and bitter summer is the real severe test, and the feeling of “the world is in this hot summer” has probably never been clearer at this moment.
break the red line

  On July 15, the United Kingdom issued the highest-level high-temperature red warning in history and directly declared a “national emergency”.
  The British “Mirror” directly used the word “Meltdown” to describe the heat wave encountered this time: On July 18 and 19, the temperature in the UK will exceed 40 degrees Celsius, refreshing the 2019 record of 38.7 degrees Celsius. Record – On the 19th, the temperature recorded at London Heathrow Airport exceeded the 40 degree Celsius mark and reached 40.2 degrees Celsius.
  The “fuss” in the UK is not an isolated case. On July 17, the French Meteorological Department also sounded the alarm: 15 provinces had a high temperature red warning and 51 provinces had a high temperature orange warning (France is divided into 96 provinces). The “red alert” provinces also include the Brittany region, known for its gloomy and cold past, with a record high temperature of no more than 25 degrees Celsius. This region has always used the coolness of summer as a holiday selling point.
  Compared with Britain and France, Portugal and Spain in the south are even hotter. Temperatures soared as high as 47 degrees Celsius in parts of both countries.
  Northern Europe, which has always been cool and even cold in the impression, is also in close contact with persistent high temperatures. Since the “unprecedented” extreme high temperature in the north and south poles at the same time in March and the temperature in some parts of the Arctic rose to 30 degrees Celsius, the Arctic Circle in July has “easily” reached 30 degrees Celsius, and Nordic countries such as Norway and Sweden have also entered a continuous multi-day A hot day above 33 degrees Celsius. According to estimates by the World Meteorological Organization, the temperature in northern Europe is at least 3 to 6 degrees Celsius higher than the same period in previous years.
  The high temperature not only engulfed Europe, but also the North American continent. In mid-July, nearly 100 monitoring stations in the southern and eastern parts of the United States set new historical high temperature records, and densely populated large cities such as Chicago, New Orleans, and Atlanta are particularly concerned.

  Nordic countries such as Norway and Sweden have also entered a hot day of above 33 degrees Celsius for several consecutive days.

  Under the blazing sun, the thermometer broke through the red line of historical records in various regions again and again, broke through people’s habits and psychological defense lines, and detonated a series of hot problems.
Air Conditioning?

  After the temperature rose to 40 degrees Celsius, there were many fires in east London, and the fire department activated a “major incident” alert; the fire in the village of Wennington in the eastern suburbs, due to high temperature and dryness, was once beyond control. Portugal and Spain were caught in unquenchable forest fires.
  High temperature, fire, and smoke have seriously affected the traffic in the above-mentioned countries: under the emergency state warning issued by the United Kingdom, the subways, trains and other rail transportation systems have all slowed down and reduced the frequency to avoid the danger caused by high temperature deformation, and advocated the public to “unnecessary and unnecessary.” Travel”, do not travel at will or try to “sunbathe” outdoors; Spain has stopped traffic in all areas affected by the fire.
  Even more cruel is the death caused by high temperature. As of July 21, the heat death toll in Spain and Portugal had climbed to more than 1,700.
  If you look at history, you will find that the above figures are not surprising. In 2003, high temperatures killed 15,000 people in France. Later, the French sanatorium learned lessons, equipped the rooms with air conditioners, installed additional ventilation systems, and used sprinklers to cool the exterior walls of the building at appropriate times, which finally reduced the toxicity of high temperatures.
  For those of us who have “continued the life of air conditioners”, the “heat death” in developed countries seems a little difficult to understand: if forest fires are difficult to prevent and outdoor temperatures are difficult to control, why do these countries not generally use air conditioners indoors?
  In fact, rich European countries have extremely low air-conditioning ownership rates. According to data from last year, only about 6% of Europeans have an air conditioner in their home. In addition to climate reasons, European households rarely install air conditioners because the installation cost of air conditioners is extremely high, even far higher than the air conditioner itself. After installation, the electricity bill is another huge expense. Due to the widespread use of clean energy or nuclear power generation in Europe, the cost of electricity is relatively high. For example, 1 kWh of electricity in Germany costs about 3 yuan, which is five or six times that of China.
  The more important obstacle is the protection of the building appearance in Europe. In some European countries, if you want to hang an external unit of a split-type air conditioner on the outer wall of an apartment, it is an act of “changing the appearance of the facade” and requires the consent of the owner of the entire building. In this way, from demand habits to cost performance, air conditioners are not easy to popularize, and it is no wonder that Europeans are quite passive when the heat wave hits.
Not a summer insurmountable?

  Why is this year so hot? One theory is that the planet’s warming comes from an increase in the amount of heat radiated by the sun. According to the law that the north and south magnetic poles of the sun’s magnetic field flip every 11 years, and the sunspot flares and other substances change drastically, it seems that the sun has indeed been in the active period of the sun in recent years, and it seems to be “hotter” for granted.
  But more people blame greenhouse gas emissions. According to one study, “human influence on climate, especially greenhouse gas emissions, increases the likelihood of South Asian heatwaves by 30 times”.
  If you are a caring person, you may have smelled the different breath of this summer from the abnormally high temperature in the past:
  On May 24, 2021, the temperature in Yekaterinburg, Russia, which has always been regarded as the “Northland scenery”, climbed to 34.2 degrees Celsius, and Moscow was even more so. It matched the record for the same period in 120 years – once, the average temperature in these Russian cities was only around 25 degrees Celsius.

  Affluent European countries have extremely low air-conditioning ownership rates.

On April 30, 2022, the sun sent a powerful solar flare

On July 5, 2022, the drought crisis in the United States continues, affecting the livestock industry

  In March, India had its warmest March since 1901. In April, the same is true.
  Also in April, Pakistan experienced a “year without spring”, which soared to 47 degrees Celsius, the highest temperature of the day in the northern hemisphere.
  The hot summer, is it “boiled” and passed? Is it possible to “naturally cool” just by hiding in a room with enough air-conditioning and waiting for the calendar to turn to October, November or later?
  The weather will eventually turn cooler and the seasons will change, but the feverish summer cannot be overcome without cost. In addition to those who died from the heat of the heat condensed into numbers and never came back, there are thousands of plants and animals that cannot speak and are not counted. “High-temperature inactivation” caused 2,000 cows to be roasted alive on a farm in Kansas, USA, and birds flying high in the high-altitude state of Gujarat in western India were “hit” by the hot air and fell to their death from the air.
  According to the latest assessment of the United Nations Intergovernmental Panel on Climate Change, if human beings cannot take it seriously and strictly limit carbon emissions at this stage, then flood disasters, crop failures, depletion of water resources, decline of wetlands and rainforests and other phenomena will be “in the next few decades”. will increase significantly and the spread of the disease will further accelerate.”
  If these are too grand and distant, and are “all human beings”, then we may all experience the inconvenience of life caused by high temperature weather: the midnight awakened by the roar of the air conditioner, and the sticky daytime… Climate change robs comfort, robs sleep, and robs focus. Everything thrown to nature will eventually be returned in full.
  The world shares this hot summer, and the world shares weal and woe. Do something for the environment, for the burning earth, before it’s too late.
