A different perspective on transgender activism

“Four years ago, I wrote about my decision to live as a woman in The New York Times, writing that I had wanted to live “authentically as the woman that I have always been,” and had “effectively traded my white male privilege to become one of America’s most hated minorities.”

Three years ago, I decided that I was neither male nor female, but nonbinary—and made headlines after an Oregon judge agreed to let me identify as a third sex, not male or female.

Now, I want to live again as the man that I am.” click here

North America has been cooling since 1998

Daily minimum temperature (Tmin) is an important variable in both global and regional climate changes, and its variability can greatly affect the ecological system. In the early 21st century, warming slowdown is seen over the North Hemisphere and North America is one of the major cooling centers. In this study, we found that Tmin experienced an obvious decline in North America during warming slowdown period. Such Tmin decline is closely related to the Atlantic Multidecadal Oscillation (AMO); the correlation between the decadal components of Tmin and AMO reached 0.71 during 1950–2014. According to composite analysis, the AMO on the positive (negative) phase takes two low‐pressure (high‐pressure) systems in the northeastern Pacific and the North Atlantic at night, accompanied by cyclonic (anticyclonic) circulations and warm (cold) advection in North America. Therefore, the analyses conclude that the Tmin decline during warming slowdown period is a result of the synchronous decrease of the AMO. The results emphasize the key role of AMO on the decadal variation of Tmin in North America.
