In page List of climate change controversies:

"

There have been many debates around the details of climate change science. Climate change deniers and "skeptics" tend to cherry-pick data or studies, and then trump up any scientific discussions or apparent discrepancies that match with their agenda.[citation needed] Many of those apparent discrepancies have been reconciled in the meantime, climate models have become more accurate, the scientific consensus on climate change has strengthened and so forth. For example, climatologist Kevin E. Trenberth has published widely on the topic of climate variability and has exposed flaws in the publications of other scientists.[1][2][3]
