Moody's is acquiring climate and natural disaster risk modeling company RMS for about $2 billion from Daily Mail and General Trust.

What to expect:
The Pacific Northwest is once again in the midst of a heat wave after already seeing its worst such event on record this summer. Temperatures are soaring into the low 100s in some areas, while dangerous heat is also affecting the South Central states and Gulf Coast.
Why it matters: The occurrence of yet another heat wave during a drought in the West is ratcheting up wildfire risks. The heat itself is a major public health risk, as extreme heat is typically the biggest annual weather-related cause of mortality in the U.S.
