I rhetorically ask this because JimZ said "From about 1980 onward, there was a minor warming trend which ended about 2000."
What's being referred to is an experimental average, so, it does no good to deny it or cite opinion. After enough research, it should be accepted. From credible sources, I have noticed 4000 ppm or 25mm many times in the past. If it was sucked out of the air with a straw and put in a glass, they would not accept...
'Donald Trump suggests he does not know if climate change is manmade, saying: 'It'll change back again'
They are still going with between 1.5 and 4.5 C and now they have ditched the best estimate of about 3 degrees C
I dont doubt climate change is happening, it always has.
I don't doubt that Man has caused some.
What I doubt is that climate change (warming that is) is in anyway dangerous.
The world is doing alright at the moment, food production is up at record levels, malnutrition and extreme poverty is down, Hurricanes...
I am not arguing whether global warming is real or not, or what might be a cause.
I am just wondering what you think of it being used as a catch-all explanation.
The last person he talked to said it wasn't a hoax.
University of Peoplesay . they have no scientists .
I ask this because when I read the answers in here from people on the denial side, it's clear that that there isn't a single one of them that has any background in atmospheric science or physics.
The worse estimate it will still take 100 years
Both figures were plucked from the air by politicians and have no real scientific relevance at all.
So, yes, the revised figure is just for political reasons.
Or is he just a dodgy sweater salesman
We will all die, this is a fact, earht globla changes are real !!!! We need to do changes and not vote for presidentn like Donald trump that dont care about earth because they are old and think just about themeselfes!!!!!!
