"Point to" is not confident enough. Even skepticalscience, the "alarmist"-side site, admits that "While clouds remain an uncertainty, the evidence is building that clouds will probably cause the planet to warm even further".

"A group of researchers from the University of Miami and the Scripps Institute of Oceanography studied cloud data of the northeast Pacific Ocean"

Study from your first link recorded cloud cover data over subset of Earth's atmosphere. It doesn't say anything about whether clouds feedback is positive, or negative. Local data is not very useful evidence, global data would be preferable.

Here is an explanation of what is cloud feedback: increase of temperature has effects on cloud formation. If feedback from changes in cloud formation is positive, it will lead to even more warming. Negative feedback would mean that changed cloud formation actually reduces warming.
