The Earth is now 40 to 50 degrees hot! The sun has "spewed fire" 36 times in 2 weeks, do they have anything to do with each other?

As the natural environment continues to deteriorate, the climate is becoming progressively more chaotic, with heat and severe cold appearing to be anomalous in both winter and summer.

For example, in 2022, heat warnings have been issued not only domestically for various regions, but also worldwide, with many regions having warnings brought about by high temperatures.

Once-in-a-century heat and extreme weather seem to have become the most common climate terms of the 21st century.

Many urban zones are already experiencing extreme heat, and temperatures of 40°C and higher are becoming common.

According to data released by the World Meteorological Organization in 2022, the past year ending 2021 has been one of the seven hottest years on record, with climate temperatures in 2021 about 1.11°C above pre-industrial levels.

The global average temperature has risen for seven consecutive years with an overall magnitude of more than 1°C.

I'm sure the wildfires in Australia are still fresh in many people's minds, although in individual areas it is still colder, and with more rainfall.

But this is due to these areas being backed by the effects of La Niña events, which as global meteorology bring cooler, rainy weather to these parts of the world.

Still, we can't ignore the overall warming, and La Niña hasn't ended so far, with NOAA already detecting a third run in 2022.

Clearly, this situation is unusual, and La Niña can bring cooling to the planet, but not nearly enough.

According to meteorologists' simulations, there will be hotter weather in the foreseeable future than in 2021.

The summer weather in 2022 coincides with the fact that the forecast in 2021 appears to be very predictable, and with global warming, people seem to be getting used to such extreme events, especially severe heat waves.

In addition to southwest China and the Basin region, the northern United States and southwestern Canada saw high temperatures that set new temperature records.

The temperature in Litton, British Columbia, even reached a staggering 49.6 degrees Celsius, pushing 50 degrees Celsius, which is the highest temperature measurement in Canada.

After 2022, meteorologists predict that global warming will be a continuing trend that will be difficult to calm down anytime soon unless humans stop emitting greenhouse gases into the atmosphere.

And as global carbon dioxide emissions rebound to near record levels in 2021, humans will still have to do more to stop global warming.

Meanwhile, scientists have recently observed that the sun's activity appears to be very restless.

According to NASA observations in July 2022, the sun's eruption activity has reached a peak in the past two weeks.

The eruptions from the Sun's M flares have brought a lot of filamentary coronal activity, and the eruptions are very visible, but the Earth's magnetic field still appears relatively "quiet" in terms of flare variability.

As of July 13, 2022, the distribution of solar flares over the past two weeks, and the number and size of sunspot variations indicate that the next cycle will see greater activity in higher dimensions.

The solar activity just mentioned is part of the solar weather variability, even for stars, which have their weather activity, similar to the planets.

Unlike solar storms, solar storms are events that occur on or near our planet.

These are reactions, geomagnetic storms, and solar radiation storms, which occur when material ejected from the Sun reaches the Earth.

The former is caused by changes in the Earth's magnetic field caused by ejected material ejected from the coronal mass.

Solar radiation storms can involve large amounts of protons and electrons, and in the near-Earth satellite environment, these storms can last for hours or even days, depending on the magnitude of the eruption.

Although solar storm radiation sounds scary, it is largely unaffected by the Earth's magnetic field, so it is simply a cosmic deep-space manifestation.

Scientists predict solar weather activity for the simple purpose of preventing catastrophic changes on Earth.

It is like monitoring Earth's weather in general, although such activity would appear a bit more complex when placed in a cosmic context.

Now that we know that sunspot activity and coronal eruptions affect the state of the Earth, scientists analyze sunspot regions daily to assess the threat through the Space Weather Prediction Center's data service.

Changes in sunspot size, number, and position are monitored and recorded to assess the likelihood of Earth-directed solar flares and coronal eruptions from active regions.

Considering Earth's weather changes in recent years and the progressively harsher natural environment, does the Sun's weather activity affect the Earth's climate environment?

According to NASA's observation, the Sun, as a giant charged energy body, carries a powerful magnetic field itself, and its magnetic field goes through a cycle, which is the solar cycle.

Every 11 years, the solar cycle undergoes a magnetic pole flip, which means that the north and south poles of the Sun switch positions.

The solar cycle affects the Sun's activity, which is directly reflected in sunspots. It is caused by the Sun's magnetic field, and as the field changes, so does the Sun's surface activity.

The method used by scientists to keep track of the solar cycle is to count the number of sunspots.

At the beginning of the cycle, solar activity is minimal, and the number of black sons is minimal. As time goes on, solar activity and the number of black sons increase.

Another change in solar activity is solar flares and coronal mass ejections, which increase during the solar cycle.

Powerful bursts of power and matter are sent into space, and it does have an impact on the Earth.

However, the solar activity that affects the most and is most visually evident is the aurora borealis, as well as radio communications, and the most extreme eruption scenarios can even affect the power grid on Earth.

For astronauts and space equipment working in space, it is important to monitor the solar cycle.

The radiation from the solar cycle can be dangerous.

If the active time of the solar cycle can be predicted early, satellites can go into safe mode to avoid damage, while astronauts will delay walking in space.

Although the solar cycle varies over 11 years, the total radiation from the Sun, in its semi-regular ebb and flow, will be at most 0.15%.

In exchange, it is said that short-term variations in solar irradiance are not sufficient to have long-term effects on the Earth's climate.

Sustained changes in solar radiation occurring over decades or centuries may have an impact on the Earth's climate system.

One might argue that scientists have monitored temperature increases and climate change events for the past several decades, is this not possible?

Long-cycle solar activity indeed has an impact on the Earth, but it is not the cause of the global warming trends we have seen in recent decades.

We cannot simply estimate global temperature and rainfall and know from that how much of it is influenced by changes in total solar irradiance.

El Niño, volcanic activity, and increased greenhouse gases all affect the Earth's temperature and weather patterns.

Scientists today use computer models to analyze all the possible changes and the associated effects.

For now, scientists agree that the solar cycle and its associated short-term changes in irradiance cannot be the main force driving the climate changes seen so far.

While climate monitoring from 1979 is based on space-based solar irradiance measurements, humans have long recorded the solar cycle by monitoring the increase and decrease of magnetically active sunspots.

For these long-term records, the evidence suggests that there is no direct correlation between the two, especially in the short-term magnitude change tables.

In general, no substantial changes in solar energy output have been recorded in the observational record over the past 35 years.

However, scientists still consider all possibilities when studying climate change, including solar variability.

three major greenhouse gases in the last 2000 years

Solar activity is more likely to help the Earth maintain its temperature, and any small decrease in the frequency of the cycle will make the Earth relatively colder.

The other thing that can be ruled out is the influence of the solar cycle on the Earth's climate.

If the sun were the main cause of global warming, then we should see all of the atmospheres from the surface to the stratosphere warming.

However in fact we are seeing warming at the surface and cooling in the stratosphere, consistent with warming from the accumulation of heat-absorbing gases near the surface, not from the sun becoming hotter.

There is no doubt that anthropogenic impacts have been a direct contributor to the overall warming event over the past few decades, and we must now face this squarely.
