Thanks for replying, these debates are fun.
So you're saying it's a big coincidence that greenhouse gasses
spiked, climate warmed and the Industrial age exploded
....all at the same time?
That's like saying it's a big coincidence that Twin Towers
happened to explode just as those jets rammed into them.
No proof is needed for what is plainly obvious. If you
want to claim there's no connection between a 757
hitting the Twin Towers and their destruction, then
the burden of proof falls on...you.

Provide a link please to that claim please.

Then why is the ice melting then? And provide a link to your data please.
I have data below showing it's a very significant rate.

Yes they do, on the last line below, read it and weep~
"NASA Earth Observatory Q and A"
"If Earth has warmed and cooled throughout history, what
makes scientists think that humans are causing global
warming now?
"The first piece of evidence that the warming over the past
few decades isn't part of a natural cycle is how fast the change
is happening. The biggest temperature swings our planet has
experienced in the past million years are the ice ages. Based
on a combination of paleoclimate data and models, scientists
estimate that when ice ages have ended in the past, it has taken
about 5,000 years for the planet to warm between 4 and 7 degrees
Celsius. The warming of the past century-0.7 degrees Celsius-is
roughly eight times faster than the ice-age-recovery warming
on average."
"The second reason that scientists think the current warming
is not from natural influences is that, over the past century,
scientists from all over the world have been collecting data
on natural factors that influence climate-things like changes
in the Sun's brightness, major volcanic eruptions, and cycles
such as El Niño and the Pacific Decadal Oscillation.
/These observations have failed to show any long-term changes
that could fully account for the recent, rapid warming of
Earth's temperature."/

EIGHT TIMES certainly is statistically significant
Let's review quickly, the highest concentration of Co2 in
650,000 years, a rate of warming 8 times faster than in
the last 1,000,000 years. And all in the last 50 years
or so, most of it in the last 20 years.
Hmmm.....what a mystery....NOT
On my side is most of the scientists of the world, NASA
with their fleet of high tech instruments and dozens of
climate specialists, and shear common sense.
On your side it's just ...you.
