Probably because man made climate change doesnt exist. Thats the only reason I can think of. In the 1970s liberals said w\that jets flying in the sky would cause the next ice age. Then as the world warmed they changed it to global warming. Now that the average temp has been dropping for the last 11 years in a row, they changed it to climate change. Also the HUGE array of scientists that now agree that global warming is bunk pretty much discredits the few handful of scientists at the IPCC that claim the earth is warming (to get more grants to study it) The fact is that I can post 4 peer reviewed scientific journal articles that say man made global warming is BUNK for every one that you can post saying it is real. Ooh yea, and remember, people magazine isnt a peer reviewed journal article. that would be like this:
Comiso, J.C. 2000. Variability and trends in Antarctic surface temperatures from in situ and satellite infrared measurements. Journal of Climate 13: 1674-1696.
What was learned
The 20-year temperature trend over Antarctica derived from the satellite data was a cooling of 0.042°C per year, while the 20-year temperature trend derived from the station data was a cooling of 0.008°C per year.
Conclusion
In view of the near-perfect agreement among the satellite and surface records over the conterminous United States, which all show little warming over the past two decades, as well as the similar finding of little warming in high-quality stations from both of the earth's polar regions, where greenhouse warming is predicted to be greatest, plus the fact that the satellite and balloon records show little to no warming over the entire earth over this period, we thus conclude that there truly has been little if any warming due to any cause over this period of time over the entire planet, and that the only reason the surface record for the globe shows warming is that outside of the United States and a few other places of high-quality temperature measurement, the surface record is just plain wrong.
Theres only about 1000 more I can post for your education.
