And if humans had never evolved or put CO2 into the atmosphere, we have no proof this would not have happened anyway.
100% wrong. It is established that mankind's actions have caused the rapid warming we are observing. Again, that is literally the fundamental basis of this topic.
Nope. That hasn't been established.
It is just a theory.
It is pushed by political organizations.
Most of the warming is done. . . BY THE SUN.

Global Warming, Carbon Dioxide and the Solar Minimum
". . . Before the IPCC formed, NOAA’s Mauna Loa Observatory in Hawaii registered co2 levelsat under 350 ppm (parts per million) with the explicit warning that if co2 exceeded that number, Mother Earth was in Big Trouble – and there would be no turning back for humanity. Those alarm bells continue today as co2 levels have risen to 414 ppm as temperatures peaked in 1998.
From the outset, the IPCC controlled the debate by limiting its charter…
"to understanding the scientific basis of risk of human-induced climate change, its potential impacts and options for adaptation and mitigation.”
In other words, before any of the science had been done, the IPCC’s assumption was that man-made activity was responsible and that Nature was not an active participant in a process within its own sphere of interest. As an interdisciplinary topic of multiple diversity, the IPCC is not an authority on all the disciplines of science within the CC domain.
While there is no dispute among scientists that the Sun and its cyclical output is the true external force driving Earth’s energy and climate system as part of a Sun-centered Universe, the IPCC’s exclusion of the Sun from its consideration can only be seen as a deliberate thwarting of a basic fundamental law of science, a process which assures a free inquiry based on reason and evidence.
It is the Sun which all planets of the solar system orbit around, that has the strongest gravitational pull in the solar system, is the heaviest of all celestial bodies and its sunspots in relation to Earth’s temperatures has been known since Galileo began drawing sunspots in 1613.
Yet the IPCC which touts a ‘scientific view of climate change’ would have us believe the Sun is irrelevant and immaterial to the IPCC’s world view and Earth’s climate; hardly a blip on their radar.. . "
The IPCC’s fatal founding flaw
The IPCC’s fatal founding flaw – Quadrant Online
"The media at large and the public that the media influences seem to believe that the IPCC is an international authority on all aspects of climate. This is a popular but false notion. The IPCC is, in fact, no more than a craftily assembled government-supported lobby group, doing what lobby groups usually do.
Its charter gives the game away:
"The role of the IPCC is to assess on a comprehensive, objective, open and transparent basis the scientific, technical and socio-economic information relevant to understanding the scientific basis of risk of human-induced climate change, its potential impacts and options for adaptation and mitigation."
Or, put more simply, the IPCC is to report on the magnitude of man-made climate change and what can be done to reduce its impact, the existence of man-made climate change being assumed from the outset.
The IPCC was established through the urgings of the International Council of Scientific Unions (ICSU) and the United Nations Environment Program (UNEP). The former is a shadowy organisation that conducted scientific projects for UNEP and wrote in-house reports. Given the amount of work it undertook, those reports probably aligned closely with UNEP thinking.
The latter is well known for blaming human activity for every change to the environment — a stance seemingly based on the assumption that the environment never changes naturally and/or that we fully understand every natural force which might make it change. By this logic any and every deviation must be man-made.. . ."
A sensitive matter
The climate may be heating up less in response to greenhouse-gas emissions than was once thought. But that does not mean the problem is going away
A sensitive matter
"OVER the past 15 years air temperatures at the Earth’s surface have been flat while greenhouse-gas emissions have continued to soar. The world added roughly 100 billion tonnes of carbon to the atmosphere between 2000 and 2010. That is about a quarter of all the CO₂ put there by humanity since 1750. And yet, as James Hansen, the head of NASA’s Goddard Institute for Space Studies, observes, “the five-year mean global temperature has been flat for a decade.”
Temperatures fluctuate over short periods, but this lack of new warming is a surprise. Ed Hawkins, of the University of Reading, in Britain, points out that surface temperatures since 2005 are already at the low end of the range of projections derived from 20 climate models (see chart 1). If they remain flat, they will fall outside the models’ range within a few years.. . .
