For instance, the warming that began in the early 20th century (1925 - 1944) is consistent with natural variability of the climate system (including a generalized lack of significant volcanic activity, which has a cooling effect), solar forcing, and initial forcing from greenhouse gases.

The warming that took place at the beginning of the 20th century, which was similar in intensity to the current one, was essentially natural in origin.

We are also in the midst of a natural warming trend that began about 1850, as we emerged from a four - hundred - year cold spell known as the «Little Ice Age.»

Even IPCC seems already to move in that direction as it has begun to emphasize adaptation to natural climate events, though there even still is an «institutional» belief in strengthening influences of potential anthropogenic warming.

I've been doing research on the topic and I agree that natural cycles were taking the Earth into an Ice Age until anthropogenic warming suddenly began to spike the average temperature of the Earth.

«We know temperature goes up and down, we know there is tremendous amount of natural variation, but for how many years must the planet cool before we begin to understand, we politicians and scientists and so on, that the planet is not warming?

It pretty simple: when warming pauses or cooling begins, that's due to natural causes; and, when warming begins again, that's due to humanity's CO2.

What's so frightening to them is that after one of the regular warming periods begins, they can see (in air bubbles trapped in glaciers from those past times) that CO2 starts increasing, and they know that this is because of the warming and thawing of vast natural stores of carbon dioxide in the oceans — as well as in the frozen or frigid earth of the northern tundra.

Assuming a good bit of this was added after the natural warming cycle was started we are probably looking at closer to 1200 ppm over the next century or two before C02 levels begin to decrease again as this natural green house locks up carbon primarily in phytoplankton blooms caused by fertilization from the new large desert regions near the equator and excessive erosion from very intense storm systems the develop in such a hot house climate.

If I'm not mistaken, the IPCC did not begin ascribing any portion of recent warming to natural variability until they needed natural variability to explain the pause.

Where natural sources of CO2 leave off and human sources begin What amount of CO2 in the atmosphere engenders ANY warming?

Anthropogenic Global Warming as a measurable entity, distinguishable form natural cycles, is yet to begin.

Since 1680 was long before co2 began increasing and also well before the industrial revolution, and — it would have taken considerable additional time for the low annual increase in co2, when it did finally begin, to have an impact on temperature, it's safe to state that the first 200 years of warming were merely natural climate variation.

Edim, no anthropogenic warming has been increasing since the industrial age began, and has only in recent decades exceeded natural variability for any sustained periods.

Furthermore most of the papers in their compilation only studied responses during the warm phases of natural ocean cycles beginning in the 70s, after most marine organisms had retreated south.

The grand mistake of the climate catastrophists was using an instrument network primarily located in industrialized NH locations and mistaking a natural warming trend beginning in the 1970 - 1980 timeframe with anthropogenic warming.

The problems begin when human activities distort and accelerate the natural process by creating more greenhouse gases in the atmosphere than are necessary to warm the planet to an ideal temperature.

Looking for any evidence that humanity is cooking the globe, Jiansong Zhou and Ka - Kit Tung (Deducing Multi-decadal Anthropogenic Global Warming Trends Using Multiple Regression Analysis) began by excluding climate change due to natural factors and more specifically, by adding the effects of AMO (Atlantic Multi-decadal Oscillation) trends that alarmists neglected to consider.

It's about the chain of natural catastrophes and devastating weather patterns that global warming is beginning to set off around the world..

If the beginning point of attribution starts at the highest temperature point in the natural cycle, then the amount of warming due to anthro will always be 100 % or greater.

It's worth considering what will happen when natural and GHG forced warming begin to re-enforce one another again.
