If it were the sun were responsible for global warming, we would expect to see the most heating occurring during the daytime hours and during the summer, when the sun is at its strongest. Yet the greatest warming has occurred at night and in the winter months. If the sun were responsible for global warming, we would expect the entire column of the atmosphere to warm, not just the surface. Instead, we observe that the upper atmosphere--the stratosphere and mesosphere--is cooling, while the surface is warming. These observed trends--great heating in winter and at night, and cooling in the upper atmosphere while the surface is warming--are what climate change theory says should happen if heat-trapping gases like carbon dioxide are responsible for the warming, and don't fit the idea that the sun is doing it. We also have satellite measurements of the total amount of solar energy arriving at the top of Earth's atmosphere from satellites since 1979, and these measurements show a slight decrease in solar energy during 1979 - 2012. In fact, Earth's warmest year on record--2010--occurred during a period where the satellite-measured incoming solar energy was near an all-time low, probably much lower than anything that has occurred for centuries. So, while it is natural to suspect the sun as the source of global warming, "if the glove doesn't fit, you must acquit!"
He quit responding to my emails when I asked him why then during the Paleozic and Mesozoic periods CO2 levels ranged from 2500 to 7000 ppm and life thrived and temps held a steady average never rising above 26 degrees Celsius. And right now CO2 levels are around 400 ppm. Whats the big problem? The left's arguement does not make logical sense...
Crickets ever since...prior to that he responded 3 or 4 times.
Wunderground was acquired by the Weather Channel.
Which itself was acquired by NBC.
As part of the progressive plan to pass off “climate change” as mainstream information.
Ask him why temperatures on our adjacent planets have also increased, commensurate with increased activity by the sun. Also, point out that upper atmospheric layers that are ‘thinner’ would not be expected to be warmed by sunlight to the same extent as those layers closer to Earth, for the same reasons that space is cold, despite sunlight.
LOL!
They fraudsters use this argument a lot, it just shows how scientific illiterate they really are.
It doesn't matter if the sun, if the sun is slightly lower or slightly higher from one month or year vs another because the sun in the last 50 years of the 20th century was still higher than it's been for a 1000 years.
The sun doesn't have to keep getting hotter & hotter to continue to warm the earth. We see this yearly with the seasons, using their logic, the tilt of the earth can't be the cause of the seasons because the sun peaks in June and then declines in July and August but even with a weaker sun July and August still are hotter (and sometimes by a lot)than June .
July and August are hotter than June because 1) The Sun is still high enough to cause warming and 2) The Earth has buffers (i.e. Oceans as heat sinks) to rapid instantaneous changes and 3) it's adding warmth from the previous months
The same with the warming in the last half of the 20th century, sure the solar cycle in the last part of the century was slightly less than the one in the 50s or 80s, but it was still extremely strong and it was adding heat to the previous extremely strong cycles.
That's why their models are flawed, they assume all changes to the sun will have an immediate drastic effect on the earth. It takes time.
And likewise, one weak cycle isn't going to immediately throw us into an ice age, pretty much for the same reason it's not as cold and snowy in October as it is February even though the sun is the same strength.
But yes, the two cycles of the start 21st century haven't been as strong as the two at the end of the 20th which probably explains why warming has stopped.
Because it’s not about “climate change”.
It’s about making “dr” Jeff Masters feel good about himself as “a good person” because he “cares about the erf”.
When discussing the state of the atmosphere in geological ages, it isimportant to remeber there were profound changes in far more variables than just temperature and carbon dioxide in the atmosphere. The changes in the atmosphere have been monumental in quantity, quality, and composition. Depending on how you go about reckoning the definitions, the Earth has had three or four atmospheres of distinctly different compositions and sizes. The Earth’s second atmosphere was up to something around 100 times more massive in quantity than today, and that far more massive and dense atmosphere was composed of something greater than 96 percent carbon dioxide. This made the atmospheric concentrations of carbon dioxide something greater than about 999,600 parts per million versus less than 10,000 parts per million in the most recent 280 million years or less than 400 parts per million in some of the recent decades, centuries, and millenia. Surface level atmospheric pressure was crushing versus today’s macro lifeforms and one atmosphere of pressure. The great pressures and the residual heat remaining from the planet formation kept the planet’s atmosphere hot despite the faint Sun paradox wherein the Sun was much less luminous at that time.
The Earth’s atmosphere has been thinning ever since the formation of the Earth and the formation of the Earth’s atmosphere. The Sun has been increasing in luminosity. The thinning of the atmosphere from upwards of 100 atmospheres down to 1 atmsophere has changed the way the atmosphere behaves and atmospheric chemistry behavees at different atmospheric pressure levels, such as recipitation and gas diffusions. The thinning of the atmosphere and atmospheric chemistries raddically changed the composition of the atmosphere and the lithosphere. The tidal drag resulting form the mutual gravitational attrations of the Earth and the Moon has resulted in the diurnal period becoming longer through the geological ages. The lengthening of the diurnal periods changed the insolation of the Earth’s atmosphere, hydrosphere, cryosphere, and lithosphere. The changes in atmospheric chemistry changed its temperature characteristics. Changes in the Eartth’s magnetic field and magnetosphere altered the earth’s energy characteristics.
Massive changes in the biosphere altered the Earth’s atmospheric and energy characteristics.
Has any atmospheric model adequately accounted for the myriad of changing factors? No, they most certainly have not.
