Global warming is an indisputable fact in the eyes of most people, but a climate change research institute published data saying that from early 1997 to August 2012, the overall global temperature change was only 0 ° C. According to this agency, It is believed that the global warming trend has stopped. If one of the following is true, the conclusion of the research institution cannot be questioned? ['The timing of the start and end of the climate trend is critical, otherwise, it will distort the conclusions of the study.', 'For the study of global climate change, the data of more than ten years is only a short-term data and does not explain the problem.', "the latest research results show that global climate change is more affected by the Earth's own movement than human activity.", 'the current computer model on which global temperature records depend is flawed, and real climate change is far more complicated than it reflects.']
