Last Month Was the Hottest June of All Time

Climate

Just like the month that preceded it, June 2014 was the hottest of its kind in our planet's history.

According to data from the National Oceanic and Atmospheric Administration (NOAA), global land and ocean surface temperatures combined for an average of 61.2 degrees, making last month the hottest June ever. That figure exceeded the previous record in 1998 by 1.3 degrees.

In addition to marking the second consecutive month with a record high global temperature, June was also the fifth month this year to rank among the four hottest of all time for its respective month. February was the only exception.

According to the NOAA, nine of the 10 warmest Junes on record have taken place during the 21st century began. That includes each of the last five years.

"We are living in the steroid era of the climate system," NOAA climate monitoring chief Derek Arndt told the Associated Press.

There are plenty of other figures that explain why Arndt would make such a statement:

  • The global sea surface temperature for Oceans in June was 1.15 degrees above the 20th century average of 61.5 degrees. That's the highest for any June on record and the highest departure from average for any month.

  • The combined, year-to-date global land and ocean average surface temperature was 57.24, tying with 2002 as the third warmest such period on record.

  • June broke heat records on every continent except Antarctica.

  • All 12 of the world's monthly heat records were set after 1997.

"This is what global warming looks like," University of Arizona climate scientist Jonathan Overpeck told the AP. "Not record hot everywhere all the time, but certainly a reflection that the odds of record hot are going up everywhere around the planet."

Shower shoes? Check. Extra-long sheets? Yep. Energy efficiency checklist? No worries — we've got you covered there. If you're one of the nation's 12.1 million full-time undergraduate college students, you no doubt have a lot to keep in mind as you head off to school. If you're reading this, climate change is probably one of them, and with one-third of students choosing to live on campus, dorm life can have a big impact on the health of our planet. In fact, the annual energy use of one typical dormitory room can generate as much greenhouse gas pollution as the tailpipe emissions of a car driven more than 156,000 miles.

States that invest heavily in renewable energy will generate billions of dollars in health benefits in the next decade instead of spending billions to take care of people getting sick from air pollution caused by burning fossil fuels, according to a new study from MIT and reported on by The Verge.

From where I stand inside the South Dakota cornfield I was visiting with entomologist and former USDA scientist Jonathan Lundgren, all the human-inflicted traumas to Earth seem far away. It isn't just that the corn is as high as an elephant's eye — are people singing that song again? — but that the field burgeons and buzzes and chirps with all sorts of other life, too.

Indonesia's president has made permanent a temporary moratorium on forest-clearing permits for plantations and logging.

It's a policy the government says has proven effective in curtailing deforestation, but whose apparent gains have been criticized by environmental activists as mere "propaganda."
