Sun cycles seen not key to recent global warming
By Bruce Nichols SAN ANTONIO, Texas (Reuters) – “Satellite data show that changes in the sun are contributing to global warming but to a smaller extent than human activity, a space scientist at the Naval Research Laboratory in Washington told a group of petroleum geologists…”
This is the third major study in the past year or so negating the “solar activity” claim of climate-change skeptics- the claim suggests that solar activity rather than human activity is responsible for modern global warming. See discussion of another report that show no major effects of solar activity on modern global warming (at this link).
“Climate-change skeptics have suggested that solar cycles may be more responsible than human activity for increasing global temperature. But (scientist Judith) Lean said her findings showed ‘the sun is a factor of 10 less than the anthropogenic.'” In other words, people (and human activity) are responsible for the vast majority of modern climate change according to this study.
