Study: Reduced Energy from the Sun Might Occur by Mid-century – cooling the climate
Despite how much the Maunder Minimum might have affected Earth the last time, Lubin said that an upcoming event would not stop the current trend of planetary warming but might slow it somewhat. The cooling effect of a grand minimum is only a fraction of the warming effect caused by the increasing concentration of carbon dioxide in the atmosphere. After hundreds of thousands of years of CO2 levels never exceeding 300 parts per million in air, the concentration of the greenhouse gas is now over 400 parts per million, continuing a rise that began with the Industrial Revolution. Other researchers have used computer models to estimate what an event similar to a Maunder Minimum, if it were to occur in coming decades, might mean for our current climate, which is now rapidly warming.
Study: Reduced Energy from the Sun Might Occur by Mid-century – cooling the climate
Silly Billy, your own source says you are full of shit. The scientists are predicting that it might slow the warming down a bit. That might give us a bit more breathing space, but not much. And the reduction is in the ultraviolet range, they do not give a figure for the reduction of the TSI. I suspect it is far less than that of the UV.
LOL
You and never doing the math...Do you ever check to see if what they say and what the evidence says are in concert? Tell me moron, which is more important as to energy that the earth can absorb?
Again you took the razor sharp scissor SKS talking points and ran with them...
Old Rocks doesn't seem to realize that there is little warm forcing power left to squeeze out of CO2, most of it was set in 500 million years ago when it was at the estimated 7,000 ppm level.
Here are but two of many published science papers showing low to very low CO2 sensitivity in a doubling of CO2:
Idso, 1998 (2X CO2 = ~0.4°C)
Over the course of the past 2 decades, I have analyzed a number of natural phenomena that reveal how Earth’s near-surface air temperature responds to surface radiative perturbations. These studies all suggest that a 300 to 600 ppm doubling of the atmosphere’s CO2 concentration could raise the planet’s mean surface air temperature by only about 0.4°C. Even this modicum of warming may never be realized, however, for it could be negated by a number of planetary cooling forces that are intensified by warmer temperatures and by the strengthening of biological processes that are enhanced by the same rise in atmospheric CO2 concentration that drives the warming.
and,
Holmes, 2018 (2XCO2 = -0.03°C)
Calculate for a doubling of CO2 from the pre-industrial level of 0.03% [300 ppm]: [formula found in text] Calculated temperature after doubling of CO2 to 0.06% [600 ppm] ≈ 288.11 K. Climate sensitivity to CO2 is ≈ 288.14 – 288.11 ≈ – 0.03 K.
The change would in fact be extremely small and difficult to estimate exactly, but would be of the order -0.03°C. That is, a hundred times smaller than the ‘likely’ climate sensitivity of 3°C cited in the IPCC’s reports, and also probably of the opposite sign [cooling]. Even that small number would likely be a maximum change, since if fossil fuels are burned to create the emitted CO2, then atmospheric O2 will also be consumed, reducing that gas in the atmosphere – and offsetting any temperature change generated by the extra CO2. This climate sensitivity is already so low that it would be impossible to detect or measure in the real atmosphere, even before any allowance is made for the consumption of atmospheric O2.
