Does wonders for the ozone.



You mean like -?

"According to a study published in the March 2002 Journal of Geographical Research by a joint research team from the University of Maryland and NASA, overall, the increased amount of CO2 in the atmosphere is speeding up the recovery of the ozone layer -- including the hole at the South Pole."

https://sciencing.com/co2-deplete-ozone-layer-4828.html

And they were saying the hole in the ozone layer seemed to increase cases and severity of sunburn. Wink

No, I mean we are rooted no matter which way you look at it, ozone, mass extinction of species more plastic in the ocean than fish in 2050 and other stuff.

Did you see my graph in this thread Lee? the industrial age has tipped the scales.

So what you are saying is you know nothing about the ozone but pontificated about it anyway? Grin Grin Grin Grin Grin

You mean the one you can't or won't give the study from whence it comes? Grin Grin Grin Grin Grin

You mean you are the author? Well done. Now you can provide the study. Wink

You still provide no answers, I will take that as an, I don't know, its ok Lee its a tricky one.

Its good to see you are shedding your blinkers.

Poor petal. Fails even a BASIC understanding of the English language. Grin Grin Grin Grin

Where does your graph come from? It can't be put into context without that. We don't know the resolution of YOUR graph. If the resolution is larger than 100 years any spikes will be lost.

You do understand resolution don't you? We are not talking New Year's here. Wink

From memory the resolution goes back thousands of years with the emphasis on the post industrial years, honey sugar plum.

So a resolution of thousands of years and they can deduce 100 year emissions. Grin Grin Grin Grin Grin Grin

Have you heard of ice core samples, sugar.

Yes petal. And if the ice cores have a resolution of "thousands of years", then looking at 100 year time series within that  "thousands of years" resolution is a fool's errand. But you probably fit that bill. Wink

I've done a search & found this:

https://www.wunderground.com/resources/climate/strato_cooling.asp

Greenhouse gases also cause stratospheric cooling

However, this recovery of the ozone layer is being delayed. A significant portion of the observed stratospheric cooling is also due to human-emitted greenhouse gases like carbon dioxide and methane. Climate models predict that if greenhouse gases are to blame for heating at the surface, compensating cooling must occur in the upper atmosphere. We need only look as far as our sister planet, Venus, to see the truth of this theory. Venus's atmosphere is 96.5% carbon dioxide, which has triggered a run-away greenhouse effect of truly hellish proportions. The average surface temperature on Venus is a very toasty 894 F! However, Venus's upper atmosphere is a much colder than Earth's upper atmosphere. The explanation of this greenhouse gas-caused surface heating and upper air cooling is not simple, but good discussions can be found at Max Planck Institute for Chemistry and realclimate.org for those unafraid of radiative transfer theory. One way to think about the problem is that the amount of infrared heat energy radiated out to space by a planet is roughly equal to the amount of solar energy it receives from the sun. If the surface atmosphere warms, there must be compensating cooling elsewhere in the atmosphere in order to keep the amount of heat given off by the planet the same. As emissions of greenhouse gases continue to rise, their cooling effect on the stratosphere will increase. This will make recovery of the stratospheric ozone layer much slower.

Greenhouse gases cause cooling higher up, too

Greenhouse gases have also led to the cooling of the atmosphere at levels higher than the stratosphere. Over the past 30 years, the Earth's surface temperature has increased 0.2-0.4 C, while the temperature in the mesosphere, about 50-80 km above ground, has cooled 5-10 C (Beig et al., 2006). There is no appreciable cooling due to ozone destruction at these altitudes, so nearly all of this dramatic cooling is due to the addition of greenhouse gases to the atmosphere. Even greater cooling of 17 C per decade has been observed high in the ionosphere, at 350 km altitude. This has affected the orbits of orbiting satellites, due to decreased drag, since the upper atmosphere has shrunk and moved closer to the surface (Lastovicka et al., 2006). The density of the air has declined 2-3% per decade the past 30 years at 350 km altitude. So, in a sense, the sky IS falling!

So all is steady for thousands of years and now there is a sudden spike in global warming which just happens to coincide with the industrial age, ALARM BELLS.

EXPERT REACTION: We've just had the hottest 5 years on record, UN Science group says time to face reality on climate


Publicly released: Mon 23 Sep 2019 at 0001 AEST | 0201 NZST


A new landmark report convened by the science advisory group of the UN's Climate Action Summit 2019 says there is a glaring and growing gap between global warming targets and reality with global temperatures since 2015 on track to be the hottest on record for any five year period. The report says that current global commitments to cut greenhouse gas emissions would still lead to a global temperature rise of between 2.9C and 3.4C by the end of the century. To actually limit warming to 2C the report says countries would need to commit to emissions reductions that are triple their current commitments. If we want to limit warming to 1.5C those commitments need to be five times greater. The good news is the authors say its not too late and that it is technically still feasible to bridge this gap but global ambitions must be increased urgently and backed up by immediate action.
