Normal for an entire Hawaiian town to burn to ashes? Maybe when there's a volcanic eruption, but I don't recall anything like this happening in tropical Hawaii.
As with most catastrophic natural disasters these days, global warning might not be the only factor but it seems to be a rather obvious one.
Abnormal weather patterns creating extreme conditions that are causing serious problems all around the world as we speak. In Hawaii, there's a drought, which is unusual, and so the landscape is more prone to wildfires and ocean storms that are getting stronger and are driving wind speeds that make wildfires more dangerous. Irresponsible agricultural practices have not helped them in Hawaii. But it is only a contributing factor.
You say you've found one fully qualified scientist who says this is normal. I'm not sure that settles matter when the overwhelming majority of climate scientists believe that global warming causes extreme weather systems and events that impact the planet in complex, varied ways.
