About 20 fires broke out in the area of Vacaville in the northern Bay Area, emergency services said, and were being collectively called the LNU Lightning Complex fire after the intense lightning storm that sparked the conflagration earlier in the week. Scientists predict an increase in such natural disasters and climate-induced issues, should global temperatures continue to spike. PHOTO: JOSH EDELSON / AFP

Near-surface air temperatures have increased on average around the world just over one degree Celsius since the mid-19th century.
