Obama is worried enough about drought that he stopped whatever else he was doing and issued a presidential memorandum called Building National Capabilities for Long-Term Drought Resilience. It’s pretty vague but basically orders federal agencies to work together on resilience and support for new technologies.
Also, according the Wikipedia, the difference between an executive order and a presidential memorandum is…there is no difference. There are different kinds though. I like that there is one called a “memorandum of disapproval”. I can think of a few people I may send those to tomorrow.
