1. global averaged temperatures.
however different latitudes vary when not averaged. funny part is some area's are getting colder and some hotter and the average then cancels most of the differences out
2. markedly?? 0.9 degrees over many decades is not a remarkable amount. infact on the 15o previous makes the 0.9o not even a 7% change.
its a fear of a future 2.5o change not an actual 2.5o already occuring.
3. adding to that the whole hype of carbon as a greenhouse gas which affects the reflection in the upper atmosphere is an empty debate. the upper atmosphere is showing cooling not warming.
4. the temperature fear is land temperature change not upper atmosphere change. and do you know what helps reflect heat up and away from land..... WATER
carbon is just the excuse to make the running out of coal/oil be switched from the fault of oil farming to be a citizens are to blame for using so much electric from coal and so much fuel from their cars. yep the petroleum companies are not getting the blame. but while citizens feel guilty and agree to pay 'carbon taxes' that money then goes towards changing the technology at no cost to the energy sector and keep them in business
take many people on this forum blaming bitcoin miners for co2. instead of blaming the energy sector for using carbon based sources to make electric.
take the banking crisis caused by private banks... but now suddenly its a public debt and figure show estimates of how much debt people are into by quantifying the debt vs population.. instead of just making it private debt as it should be where the banks owe people money
its like people blaming fir coat customers for buying fir. when it should be the manufacturers for making coats using animal fir
but hey. while we pay for new electric plants, the change of temperatures wont get affected because the greenhouse gas of the upper atmosphere is not showing the effects they are fearmongering.. i said this before elsewhere but. the truth is in the next 50 years we will run out of oil/coal anyway.. its not in unlimited supply
.. better efforts can be made by desalinating sea water and letting it irrigate over land to stop it drying out.
