&nbsp;Perhaps, arson is another possibility.&nbsp; Several fire experts I talked to at the AMS wildfire meeting thought the powerlines were the most probable cause, but a definitive evaluation is not yet available.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">What&nbsp;<strong>is<\/strong>&nbsp;clear is that LA did not shut off the power to the region even AFTER the fire was initiated and that only limited fire-fighting resources were in place before the fires began.&nbsp;&nbsp;<strong>Not good.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Bottom Line:&nbsp; &nbsp;A very skillfully predicted Santa Ana event with record-breaking winds hit LA earlier this month. Two wet winters resulted in unusually high levels of dried fuels. Human ignitions initiated the fires.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Influence of Global Warming<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There are several media
