7. TWO IMPORTANT QUESTIONS FOR CLIMATE RESEARCH IN 2014: Are we under communicating
1.Uncertainties associated with climate models
2.Natural explanations for modern climate change ?
10. Essence of science: The art of thinking with an open mind, without being biased by what you believe
11.
12. Is modern climate change unusual ?
No
Focus on a real problem
Yes
Is CO2 responsible for climate change ?
No
Focus on a real problem
Yes
Are humans responsible for CO2 increase ?
No
Focus on a real problem
Yes
Focus on CO2 reduction
29. Is modern climate change unusual ?
No
Focus on a real problem
Yes
Is CO2 responsible for climate change ?
No
Focus on a real problem
Yes
Are humans responsible for CO2 increase ?
No
Focus on a real problem
Yes
Focus on CO2 reduction
CO2 increases because of humans
Climate is controlled by CO2
Modern climate change is unusual:
DANGER
33. Assumed natural climate development according to models
Conclusion: More than 100% of the temperature increase since 1965 is caused by man’s activity

37. The spectral signature
of measured and modeled data
Do climate models at all reproduce natural climate variations ?
54. The "Pacific Decadal Oscillation" (PDO) is a long-lived El Niño-like pattern of Pacific climate variability. The climatic fingerprints of the PDO are most visible in the North Pacific/North American sector.
55. The thin line indicate annual PDO values, and the thick line is the simple running 7 year average

59. The thin line indicates the annual value, and the thick line is the simple running 11 year average.
The AMO is basically an index of North Atlantic sea surface temperatures (SST). The AMO index appears to be correlated to air temperatures and rainfall over much of the Northern Hemisphere. The AMO index also appears to be associated with changes in the frequency of North American droughts and is reflected in the frequency of severe Atlantic hurricanes.
