The whole situation regarding global warming is very worrying as scientists keep reporting that each year is getting hotter on average globally and this year 2015 is set to be the hottest yet. yet we keep driving cars, going on aeroplanes and industry keeps belting out greenhouse gases. I have just seen that over in China the biggest Typhoon has just struct the coast there and it could be the biggest storm for 40 years. What if we go over the tipping point and our weather starts to seriously affect food production worldwide. I think we are heading for major problems and we need to start sorting this out quickly.
I have just used one of the online calculators to assess my carbon footprint. Since I don't run a car or use flights, I would like to think my footprint is low.Well, it is, but not low enough. Apparently, the average is about 10 tons, whereas the sustainable target for 2050 is 2 tons! I come in about 3 tons.Most of that is 'indirect' simply through supermarket shopping etc. Not easy to lower that whilst living in our current system?
Since it's beginning the earth's physical and atmospheric makeup has been in a constant state of evolution. There have been ice ages and periods of warming, as well periods of higher and/or lower oxygen content. There have been volcano's and earthquakes(far exceeding anything we experience today),as well asteroids impacting the earth, and this all has served to change earths makeup allowing for the existence of differing life forums, and when they have reached their potential, send them into extinction, paving the way for a species more suitable for the changing environment. What we have over looked is that the earth itself has a lifespan, does that mean the end of mankind as we know it ,opening the door for a more advanced species? Is earth just a starting point for the human race, is man's future out amongst the stars living in self sustainable colonies??? According to a study published in September, the earth can support life for another 1.75 billion years providing nuclear holocaust, an asteroid ,or some other disaster doesn't intervene. Stephen Hawkins(a noted theoretical physicist) said in a a lecture on black holes for BBC such a disaster is imminent ,that it is but a matter of time and we must tread lightly for it will be at least a hundred years before we have advanced to such capabilities technologically. Even if there appears no disasters the earth will in the next 1.75 -3.25 billion years travel out of the solar systems habitable zone into the hot zone. Is colonizing space the first stage to extinction of mankind as we know it, allowing for a human species more suitable for life amongst the cosmos???
