I'm sick of both gas guzzlers and environmentalist that don’t know what they are talking about. I forgive the apathetic people up to an extent.
Much of this culminates out of the myth that earth is this cuddly thing and we the only destructive elements at play. You would not want to have lived in the volcanic age. Ecology is about saving natural habitats that we depend on. Many habitats have existed/not existed several times before humans came along. However the earth has a finite life like everything. What we have to make sure of is that is that we don't shorten it to the extent we don't have a plan B or at the very least the best innings. If we want to survive beyond when the earth will be inhabitable then there will need to be a plan B. But that could take hundreds of years to develop, if it is possible. Also the fight against climate change is not about blame. We can cause some global warming, but also it can occur without us. So the point of fighting climate change is much more about fighting for our survival and the things we value, than restoring this cute and cuddly version of the earth that never existed. Notice I omitted the words 'natural' and 'man made'. That is because in the physical world it impossible to separate anything from nature. Everything is nature. This challenge requires some passion no doubt, but we can’t do without intelligent decisions. Many things you might think might work intuitively might not be the best option at all. The first job is the shorter term solutions so we can come up with the longer term solutions.
Sunbathing would imply you would want more global warming. Global dimming counteracts global warming; this has been known for a long time. The rate of global diming is decreasing. One of the more respected scientist in the climate, the guy that discovered the hole ozone layer (which many people get mixed up with global warming for some reason), has come up with one of the most feasible, and economically viable solutions to global warming. You might not like it. It involves sending rockets filled with sulphur to high altitude releasing the payload. How does he know this works? Well he studied volcanic super eruptions, crucially the ones with enough force to send sulphurous material to very high altitudes. This material is then swept all the way round the earth causing an overall cooling effect due to dimming. It is this type of phenomena that would have helped kick-start the type of atmosphere/climate that eventually gave rise to humans and most animals. The down side is there will be acid rain. But this is a small price to pay. He even conceded that a small gap in the ozone layer might not be so much as problem as not taking action against global warming.
There irony of those videos is they are showing jet trails. The jet trails are caused by water vapour, the actul polution from the planes will not be visible from the ground.
Cloud seeding is also something that has been done for decades but it doesn't look thike a contrail, none of this is covered up.
