So what is causing the current warming in the past century, cycles don't just happen there are reasons.
Why are we warming now if not for the increased CO2 levels.
we have been warming for the last 16000 years since the peak of the last ice age...
the past 1 century is part of that 160 centuries...and we are not to the point of the average peak of the inter-glacial periods of the past.... todays average global temp is about 58'f...the last 20 interglacial periods have peaked about 73'f
For this poll, "climate science" refers to the overwhelming scientific consensus that the planet is warming and humans are contributing. Evolution refers to Darwinian evolution, not micro-evolution or any other creationist spin on it. Do you accept evolution and climate science? Do you accept one and not the other? Do you accept neither?
The theory of CAGW has evolved from 1980s acid rain and save the whales campaigns, just as Darwin predicted!
It could spontaneously mutate into something more ridiculous and manipulative but that will require a hippie drum circle, a hacky-sack and weed brownies.
1957 - US oceanographer Roger Revelle and chemist Hans Suess show that seawater will not absorb all the additional CO2 entering the atmosphere, as many had assumed. Revelle writes: "Human beings are now carrying out a large scale geophysical experiment..."
1958 - Using equipment he had developed himself, Charles David (Dave) Keeling begins systematic measurements of atmospheric CO2 at Mauna Loa in Hawaii and in Antarctica. Within four years, the project - which continues today - provides the first unequivocal proof that CO2 concentrations are rising.
1975 - US scientist Wallace Broecker puts the term "global warming" into the public domain in the title of a scientific paper.
1989 - UK Prime Minister Margaret Thatcher - possessor of a chemistry degree - warns in a speech to the UN that "We are seeing a vast increase in the amount of carbon dioxide reaching the atmosphere... The result is that change in future is likely to be more fundamental and more widespread than anything we have known hitherto." She calls for a global treaty on climate change.
1992 - At the Earth Summit in Rio de Janeiro, governments agree the United Framework Convention on Climate Change. Its key objective is "stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system". Developed countries agree to return their emissions to 1990 levels.
Most of us, and I include myself here, did not understand or concern ourselves with climate change predictions for decades. It does require one to be seriously engaged and willing to learn.
It might be worthwhile to note that no Chinese nationals are revealed in this early research. In case you were wondering.

oh please
do we humans pollute...yes
do we humans waste...yes
do we humans overdevelop and cut trees(a natural radiant cooler and co2 user/o2 PRODUCER)...yes
are we humans the cause of the earths climate changes........NO
I live right on the shore on Long Island...long Island was CREATED by the last glaciers.....did we CAUSE the warming 10's of thousands of years ago to melt the glaciers????
The ancient Greek philosopher Plato(427-347 BC), wrote about major climate changes in his day.
when writing to "Timaeus," he argued global warming occurs at regular intervals, often leading to great floods.
Plato's student, Aristotle (384 BC to 322 BC), also recorded evidence of global warming in his work, "Meteorologica."
In the first century AD, an ancient Roman named Columella wrote an agricultural treatise called, "De re rustica." In it, he discussed global warming that had turned areas once too cold for agriculture into thriving farm communities. Columella cites an authority named Saserna who recorded many such cases. According to Saserna, "regions which formerly, because of the unremitting severity of winter, could not safeguard any shoot of the vine or the olive planted in them, now that the earlier coldness has abated and weather is becoming more clement, produce olive harvests and the vintages of Bacchus [wine] in greatest abundance."
In the Middle Ages, people began recording the temperature and climate-related phenomena, such as the dates when plants began to blossom annually.
We know that during a warm period, the Vikings established settlements in Greenland where perpetual ice had previously covered the land. Ancient Norse records tell us these settlements were abandoned after 1250 when falling temperatures made farming less viable and spreading ice in the sea made transportation more difficult.
sorry but your fascist rhetoric about the natural cycles being man-made is false
You might have a point there, especially the snobs from Long Island.
