Having said that, I can speak to your comment on global warming. People reject it because:
1. Many of us lived through the 1960s and 1970s, when the government and scientists claimed we were heading into an ice age. Didn't happen.
2. Many of us lived through the late 1970s and 1980s when the media and environmentalists claimed that Earth would be a lifeless rock by the end of the century due to deforestation. Didn't happen.
3. In 2005, climate scientists predicted that by 2010, global warming would cause oceans to rise to the point that populations would be decimated, and we would have 50 million "climate refugees" fleeing these flooded areas of the globe. Didn't happen.
4. NASA, CRU, NOAA, and other government and scientific organizations have been caught falsifying data.
5. There are claims that federal funding is biasing climate research; that the federal government isn't just funding research, but are buying science that promotes specific agendas.
Sure, if you only look at scientific climate data, it may look like climate change is an issue. However, if you look at government behavior, scientific scandals, evidences of falsified data, historical climate facts, and even current temperatures, there is more than enough evidence to cast a serious doubt on the accuracy and even legitimacy of climate change data, don't you think?
