Combating climate change—it’s not optional. It’s essential at EPA. We will move with a sense of urgency because we know what’s at stake.—US Environmental Protection Agency (EPA) Administrator Michael Regan, announcing the resumption of the agency’s focus on climate change (March 17). Last month, the EPA updated its Climate Change Indicators website with data from a delayed 2017 report, which states for the first time in the agency’s history that humans are, at least in part, driving climate change.
It is thinkable that the investigation of the behaviour of migratory birds and carrier pigeons may some day lead to the understanding of some physical process which is not yet known.—Albert Einstein, in a recently rediscovered letter dated October 18, 1949, to radar researcher/actor Glyn Davys. The letter was published in full on May 13.
