Because globull warming is more religion than science:
Scientists working on a landmark U.N. report on climate change are struggling to explain why global warming appears to have slowed down in the past 15 years even though greenhouse gas emissions keep rising.
Leaked documents obtained by The Associated Press show there are deep concerns among governments over how to address the issue ahead of next week’s meeting of the Intergovernmental Panel on Climate Change.
Climate skeptics have used the lull in surface warming since 1998 to cast doubt on the scientific consensus that humans are cooking the planet by burning fossil fuels and cutting down CO2-absorbing forests.
The IPCC report is expected to affirm the human link with greater certainty than ever, but the panel is under pressure to also address the recent lower rate of warming, which scientists say is likely due to heat going deep into the ocean and natural climate fluctuations.
