The weather in Portland

In science, every time we talk about the climate change of the earth, there will be two voices. One is global warming, and the other is that our earth has not warmed or even cooled down, and it may enter what we call the "small glacier" era. Therefore, this makes many people feel very strange. Is our planet getting warmer or colder?

No, it snows a lot in April in the United States, especially in Portland, which is extremely rare. Some people say that our statement about global warming is "wrong" and the earth is greatly cooling down. What is this? Let's discuss this question, is the earth cooling down greatly?

According to CNN, a record-breaking snowfall occurred in Portland, Oregon, in the northwestern United States. This snowfall is the first snowfall observed in April since there are relevant records in the local area.

According to the data of National Weather Service, the last measurable snowfall in this area, that is, the latest snowfall on record, was 82 years ago.

Therefore, this is the first snowfall in 82 years in Portland, USA, and the snowfall intensity is not low. The urban area recorded 2 inches (about 5 cm) of snowfall. In some parts of Oregon, the thickness of snow will reach 30 to 60 cm, which is rare. In addition, there were different degrees of snowfall in Beaverton, Tegard-tualatin and Vancouver.

Of course, this snowfall has also brought many impacts. Under the sudden snowfall, more than 77,000 users lost power in their homes, and some sections of Seaborn Side Street, Northwest Skyline Avenue, Southwest National Assembly Highway and Northwest Cornell Road were all closed and roads were interrupted. So it can also be seen that it doesn't often snow in these areas, and problems will occur when it snows.

At the same time, according to climate monitoring, as the temperature drops, the snowfall in this area may continue. Therefore, it may lead to more rare snowfall in this area. What the hell is going on here? Is it true that our earth has cooled down dramatically and a "new stage" of global climate change has emerged? Is it true that scientists generally believe that global warming is "fake"? We'll see.

Of course, for the great cooling of the earth, it is necessary to enter the Little Ice Age, which is the most discussed "topic" under the argument of global warming. Indeed, many scientists or research institutions have said that the earth will enter a small glacier. Give a simple example.

On 20 15, People's Daily pointed out a news that "in 2030, the sun hibernated and the earth entered the Little Ice Age", which triggered a heated discussion among many people.

This is the conclusion from the meeting of the Royal Astronomical Society-Professor Zarkov's research team from valentina that the earth entered a small glacier according to the change of solar activity cycle. This report clearly shows that the sun has a "double layer phenomenon".

That is, one convection area is close to the surface of the sun and the other is deep inside the sun. The simulation shows that when these two levels of electromagnetic waves are completely mirror images of each other, it will destroy the stability of the sun and appear almost completely offset.

This will lead to the weakening of solar activity, which is expected to decrease by 60% around 2030, when the earth may enter the "Little Ice Age". Therefore, this study shows that the temperature drop of the earth may occur.

Is the rare snowfall in the United States that the earth is "cooling down" and wants to enter a small glacier? First of all, let's answer what the research team said about solar activity.

Zarkov's team found that solar activity is expected to peak in 2022 in the 25th cycle of solar activity, which is a problem.

As we all know, we are now experiencing a new solar activity period-11year. According to the situation of space monitoring, this cycle enters 20 19 years, which is the initial stage of a new round of activity, and 2022 is the peak of solar activity.

What does this mean? The activity of the sun is on the rise, and dozens of satellite chains of American satellite companies have been destroyed this year because of the activity of the sun.

This round is expected to be the largest cycle of the sun-solar activity is expected to reach its peak around 2025. Zarkov's research team believes that it is expected to reach its peak in 2022. What does that mean?

There is something wrong with the data they simulated. So it can directly explain that there is something wrong with the solar activity cycle they said. Then it is even less likely that the earth will enter a small glacier in 2030. However, according to the expected cycle, it will develop to the minimum period after 2025, which means that the activity area will be weakened, which is a trend.

Therefore, from the comparison of this basic data, it can be seen that it is unlikely that the sun will sleep in 2030 and the earth will enter the Little Ice Age. After all, has the earth cooled down greatly, or has it entered the Little Ice Age?

As far as we know, there is no possibility of a big temperature drop on the earth. The earth is still warming, which is a "positive" statement given by the data.

For example, 202 1, although La Nina changed the weather pattern and suppressed the global temperature. However, in 20021year, the global average temperature still reached 14.7 degrees Celsius, making it one of the hottest La Nina years and the sixth hottest year in history.

Meanwhile, according to the report of NOAA and NASA, the global average temperature in recent 10 years is about 1. 1 degree Celsius higher than that in 40 years ago. American researchers believe that early signs also show that global warming is accelerating, and 2022 will rank among the top ten hottest years. So the earth has not cooled significantly.

What about the rare snowfall in America? In fact, it is a normal climate change in the United States. A "cold vortex" appeared in gulf of alaska, USA, heading south from Canada. As a result, this wave of cold air developed directly with the warm current of the United States, forming an inland gale with a speed of 50 miles per hour.

It directly formed the condition of sufficient water vapor, which led to rare snowfall in many places in the United States. Of course, this may also be a sign of climate change, so maintaining the climate is the key to the future.

Generally speaking, the complexity of climate has appeared all over the world, and the rare snowfall in the United States also shows the urgency of changing the climate. Including the rare high temperature in the United States last year, which was caused by climate change.

This year, it can be said that rare snowfall occurred before the high temperature in the United States, which also shows the complexity of the climate. This is the general situation.

Of course, once again, global warming is still happening, and there is no obvious cooling. We are about to enter the Little Ice Age, so don't get me wrong.
