Our little planet Is millions of years old. We dont really know how its cycles work, we dont know if its human causes or a natural cycle that is accelerating naturally. It's pure arrogance to say our little bit of research in the last 100 yrs tells us anything, our existence and scientific knowledge here is a split second in time compared to the lifespan of Earth.
For these changes in our environment to be used for political purposes and virtue signaling, shaming and making money is shameful.
The fact the noone is speaking of the unforeseen and seemingly self healing of the "ozone hole" over the poles shows me that it's not fitting certain scientific points of view and being ignored.
Further evidence i think that the recent uproar over "climate change" is more about advancing certain groups agendas and not really researching the true causes of these changes.
Yes, we do know how its cycles work, and we know from the geologic record that temperature changes even close to what we see today have only occurred before following major global disasters - massive, continent-wide volcanic eruptions, asteroid impacts, and so on. That is the thing about geology - we can find out what went on in the past without having had to be there personally. And sometimes what we find leads us to make predictions about further discoveries, which are then proved true. You seem to have failed to attend school, so do not appreciate how understanding increases, with each discovery leading to further questions and then more answers.
It is not a political matter, but a matter of whether or not some of the human race continues to exist. It is shameful that some people are so massively ill-educated that they cannot tell the difference between political and scientific issues, and so selfish that they pretend that there are no problems rather than risk an iota of their personal comfort.
The ozone hole is a completely different matter, and no, it hasn't gone away. However, world-wide legislation was passed in 1989 banning CFCs, the main culprit in its expansion, and so the "holes" (areas of depleted stratospheric ozone) - there were usually two, one over each pole, but the southern one was larger, and occasionally a third over Tibet - started to close. it is expected that the ozone layer will have returned to the pre-1980 state by 2075. Ozone is continuously created and removed by natural forces which, without human interference, are in balance, so as the human contaminants in the atmosphere become fewer the damage will indeed heal itself. However, recently some further depletion was noted, and it has been discovered that one or more factories in China have restarted CFC production in defiance of the Montreal Protocol.
While ozone depletion can cause cancer, and if taken too far could make terrestrial life impossible on Earth, as until the recent spike was noticed we seemed to have dealt with the cause there was no further need to talk much about it. It is not related to climate change, which is mainly caused by greenhouse gases such as CO2, CH4, and water vapour as well as some less well-known ones. Nor are any of those related to the toxic air quality in many cities. Different pollutants have different effects. There is also the direct result of too many humans living in too many cities - the urban heat island effect is having a direct effect on the overall global temperature because of the sheer number and size of human settlements.
All natural factors have now been researched, and we now know that without humans, the Earth would be in a cooling phase.
