Why is the sun so hot in 2022?
Climate change made hot temperatures more likely this summer.
The Sun is getting hotter, adding heat to the global warming that has been linked to greenhouse gases that trap heat in the atmosphere. Solar radiation reaching the Earth is 0.036 percent warmer than it was in 1986, when the current solar cycle was beginning, said a study published on Friday in the journal Science.
Earth's temperature has risen by 0.14° Fahrenheit (0.08° Celsius) per decade since 1880, but the rate of warming since 1981 is more than twice that: 0.32° F (0.18° C) per decade. 2021 was the sixth-warmest year on record based on NOAA's temperature data.
In short, the sun is getting farther away from Earth over time. On average, Earth is about 93 million miles (150 million kilometers) from the sun, according to NASA (opens in new tab). However, its orbit is not perfectly circular; it's slightly elliptical, or oval-shaped.
Next year is forecast to be one of the hottest years on record and even warmer than 2022, experts have said. Met Office scientists estimate that 2023 will be the 10th consecutive year in which global temperatures will be at least 1C above pre-industrial levels, measured as the period from 1850 to 1900.
Hot, Hot, Hot
No question about it: This summer weather is going to be remembered as a hot one nationwide. Only in New England and around the Great Lakes will the overall average temperatures tilt toward “seasonably warm,” but that's based on a wave of unseasonably cool air that arrives in September.
Day-to-day "hotness" fluctuations of the Sun are most likely due to changes in humidity.

Burning fossil fuels releases greenhouse gas, which traps heat in Earth's atmosphere. Today, the planet is warming faster than ever. This is causing serious changes to our environment.
Since 1880, average global temperatures have increased by about 1 degrees Celsius (1.7° degrees Fahrenheit). Global temperature is projected to warm by about 1.5 degrees Celsius (2.7° degrees Fahrenheit) by 2050 and 2-4 degrees Celsius (3.6-7.2 degrees Fahrenheit) by 2100.
How much hotter will it be 2030?
AUnderstanding Global Warming of 1.5°C*
warming above pre-industrial levels, with a likely range of 0.8°C to 1.2°C. Global warming is likely to reach 1.5°C between 2030 and 2052 if it continues to increase at the current rate.
What is the hottest temperature ever recorded on Earth? The highest temperature on record belongs to California's Death Valley which, in 1913, reached a temperature of 134 degrees Fahrenheit, or 56.7 degrees Celsius, Al Jazeera reports.
But don't worry. It still has about 5,000,000,000—five billion—years to go. When those five billion years are up, the Sun will become a red giant. That means the Sun will get bigger and cooler at the same time.
“In this process of the sun becoming a red giant, it's likely going to obliterate the inner planets … likely Mercury and Venus will be destroyed,” Blackman said. Earth may survive the event, but will not be habitable. Once the sun completely runs out fuel, it will contract into a cold corpse of a star – a white dwarf.

This year broke temperature records globally, with the UK witnessing highs of more than 40°C – but 2023 could be even hotter. That's the estimation made by the Met Office, which predicts that next year will become the tenth in a row to see the Earth's temperatures 1°C above the average.
The average global temperature for 2022 is forecast to be between 0.97°C and 1.21°C (with a central estimate of 1.09 °C) above the average for the pre-industrial period (1850-1900): the eighth year in succession when temperatures have exceeded 1.0°C above pre-industrial levels.
Earth's average temperature in 2023 is forecast to be between 1.08 and 1.32 degrees Celsius higher than it was before about 1900, when humans started burning fossil fuels more ferociously. A degree hotter might not seem like much, especially as much of the US emerges from a frigid winter storm.
“However, it is still likely that 2022 will be above 1.0C and hence continue the series of warmest years for global temperature since 1850.” While this is good news for fans of warmer climes, the Met Office is currently predicting April weather to be mild or "very mild" with spells of colder conditions also possible.
In 2022, the contiguous U.S. experienced its third-warmest summer (June-August) on record with an average summer temperature of 73.9°F—which is 2.5°F above long-term (1901-2000) average. Summer temperatures were much above average for most of the Lower 48 states.
The hottest time is around 3 p.m. Heat continues building up after noon, when the sun is highest in the sky, as long as more heat is arriving at the earth than leaving. By 3 p.m. or so, the sun is low enough in the sky for outgoing heat to be greater than incoming.
Why can't I tolerate heat?
Those with heat intolerance may have a disorder called dysautonomia that affects their autonomic nervous system. The autonomic nervous system helps regulate automatic functions of the body, including the body's response to heat. Several medical conditions can cause dysautonomia, including: diabetes.
The sun has been increasing its brightness by about 10% every billion years it spends burning hydrogen. Increased brightness means an increase in the amount of heat our planet receives.
Eventually, the Earth will lose its orbital energy and spiral into the Sun, even in the event that the Sun doesn't engulf the Earth in its red giant phase. A whole lot of factors will come into play in the Solar System's far future, but in the end, Einstein himself will have the last say.
Over millions of years, Earth's rotation has been slowing down due to friction effects associated with the tides driven by the Moon. That process adds about about 2.3 milliseconds to the length of each day every century.
JOSHUA: Right, so the sun is about four and a half billion years old, and in about five billion years, it's going to start to run out of its fuel. And then it will expand into what's known as a red giant.
Earth's warming trend continued last month, with September 2022 tying with 2021 as the fifth-warmest September in 143 years. The tropics also heated up, with an above-average number of tropical cyclones spinning around the globe, according to scientists at NOAA's National Centers for Environmental Information (NCEI).
Not likely, says Gebbie, because there's now so much heat baked into the Earth's system that the melting ice sheets would not readily regrow to their previous size, even if the atmosphere cools.
The 2010s were by far the hottest decade on record. Every decade has averaged hotter than the prior one since the 1960s.
💦 We'll get a 60 centimeter rise in sea levels. 🌪 Extreme weather events will multiply and become more intense as temperatures increase. 🏜 Droughts will become common in most of Africa, Australia, southern Europe, southern and mid US, Central America and the Caribbean, and parts of South America.
Scientists say eight years left to avoid worst effects.” : “IPCC climate report gives us 10 years to save the world.”
Will global warming last forever?
Greenhouse gas concentrations and global temperatures will not increase indefinitely — today's carbon dioxide buildup and warming trend must eventually top out and then reverse as the atmosphere gradually recovers.
By the year 3000, the warming range is 1.9°C to 5.6°C. While surface temperatures approach equilibrium relatively quickly, sea level continues to rise for many centuries. Figure 10.34.
Increases in average global temperatures are expected to be within the range of 0.5°F to 8.6°F by 2100, with a likely increase of at least 2.7°F for all scenarios except the one representing the most aggressive mitigation of greenhouse gas emissions.

At least five major ice ages have occurred throughout Earth's history: the earliest was over 2 billion years ago, and the most recent one began approximately 3 million years ago and continues today (yes, we live in an ice age!).
It is commonly held that the maximum temperature at which humans can survive is 108.14-degree Fahrenheit or 42.3-degree Celsius. A higher temperature may denature proteins and cause irreparable damage to brain.
New University of Melbourne research has revealed that ice ages over the last million years ended when the tilt angle of the Earth's axis was approaching higher values.
Formation. When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun.
The core is found about 2,900 kilometers (1,802 miles) below Earth's surface, and has a radius of about 3,485 kilometers (2,165 miles).
It is the pull of the Moon's gravity on the Earth that holds our planet in place. Without the Moon stabilising our tilt, it is possible that the Earth's tilt could vary wildly. It would move from no tilt (which means no seasons) to a large tilt (which means extreme weather and even ice ages).
How long will Earth last?
At the current rate of solar brightening—just over 1% every 100 million years—Earth would suffer this "runaway greenhouse" in 600 million to 700 million years. Earth will suffer some preliminary effects leading up to that, too.
In 2000, scientists looked to date what they thought was the oldest star in the universe. They made observations via the European Space Agency's (ESA) (opens in new tab) Hipparcos satellite and estimated that HD140283 — or Methuselah as it's commonly known — was a staggering 16 billion years old.
The Sun could not harbor life as we know it because of its extreme temperatures and radiation.
You might think it would suddenly become very cold. But it wouldn't. You wouldn't even notice the difference. Our planet has stored enough heat in its atmosphere and oceans to keep us warm for those five seconds without the Sun.
If it were gone tomorrow, the tides wouldn't totally vanish, but they'd be much less impressive. The tides we enjoy today get about two-thirds of their movement from the Moon. On a moonless Earth, the oceans would still move beneath the sway of the Sun's gravity, but it would be much smaller.
In this way the Sun consumes about 5 billion kilograms (5 million tons) of its nuclear hydrogen fuel every second. Yet the Sun is so large that it has been burning hydrogen at this rate ever since it formed some 5 billion years ago, and it will continue to burn steadily for at least another 4 billion years.
Per NOAA's data, 2022 has been the sixth-warmest year on record from January through August, with a global average temperature 1.55 degrees higher than the 20th-century average. Of the annual records, 2016 remains the warmest, but there is a less than 0.1 percent chance that 2022 manages to exceed that warmth.

Sacramento set a new record for the highest temperature ever recorded downtown — 116 degrees — as an extreme heatwave continued into another week on Tuesday.
Close to sunset and sunrise when the sun is close to the horizon the light has a much longer path through the atmosphere, enhancing this effect. By the time the light reaches us most of the blue light is scattered away, giving us sunsets that are orange/red in color.
Will 2023 be a hot summer?
On top of that, global average temperatures are expected to rise as greenhouse gas emissions continue to climb. As a result, the Met Office predicts 2023 will be one of the hottest years on record.
The chance of El Niño developing is negligible during boreal winter 2022/2023, slightly increasing after, but still with low chance, around 25% towards the end of the forecast period (May-July 2023).
The warmest years in the instrumental temperature record have occurred in the last decade (i.e. 2012-2021). The World Meteorological Organization reported in March 2021 that 2016 and 2020 were the two warmest years in the period since 1850.

It's the hottest year-round spot in the world, with the average annual high temperature coming in at a blistering 106.1 degrees F.
Without the vegetation and soil moisture, the Plains acted as a furnace. The climate of that region took on desert qualities, accentuating its capacity to produce heat. A strong ridge of high pressure set up over the west coast and funneled the heat northward across the Upper Midwest and Great Lakes.

In 2022, the contiguous U.S. experienced its third-warmest summer (June-August) on record with an average summer temperature of 73.9°F—which is 2.5°F above long-term (1901-2000) average. Summer temperatures were much above average for most of the Lower 48 states.
In approximately five billion years, our own sun will transition to the red giant phase. When it expands, its outer layers will consume Mercury and Venus and also reach Earth.
In the Bible, (Matthew XVI: 2-3,) Jesus said, “When in evening, ye say, it will be fair weather: For the sky is red. And in the morning, it will be foul weather today; for the sky is red and lowering.”
Why did the sun look weird today?
The unusual colour of the sky and the redness of the sun today is likely to be due to smoke from wildfires occurring over northern Iberia along with desert dust high up in the atmosphere originating from North Africa.
