According to his about page, the host is monitoring the UV light of Earth closely to relate earth changes to extreme levels of UV.  He believes that this change in UV levels could also be due to "a possible binary star companion to our sun." 
In his videos, he tracks extreme weather events such as typhoons, wildfires, and hurricanes. He watches the night sky through telescopes and tracks stars and celestial phenomena. While not a trained scientist, MrMBB333 reads many scientific articles (although most are not peer reviewed) and provides his own commentary.
