Global emissions of the potent greenhouse gas methane hit an all-time high in 2017, according to a pair of new studies released this week by researchers with the Global Carbon Project. Agriculture, landfill waste and fossil fuel production are driving the sharp increase in methane emissions from human activities, reports Maria Temming of Science News.

Alaska in March is supposed to be cold. Along the north and west coasts, the ocean should be frozen farther than the eye can see. In the state’s interior, rivers should be locked in ice so thick that they double as roads for snowmobiles and trucks. And where I live, near Anchorage in south-central Alaska, the snowpack should be deep enough to support skiing for weeks to come. But this year, a record-breaking heatwave upended norms and had us basking in comfortable—but often unsettling—warmth.

If the world gets warmer by two degrees Celsius, we’re screwed. To prevent that, the United Nations signed the Paris Agreement, an international treaty designed to keep the average global temperature “well below 2°C above pre-industrial levels”…A.K.A. what the Earth was like before factories started spewing greenhouse gases into the air.
Last month, Phoenix enduring a blistering heat wave, with temperatures so high that airport officials had to cancel dozens of flights. The reason was two-fold. First off, some jet engines risk catching on fire in extreme heat. And when air gets hot, it expands and becomes less dense—so an airplane’s wings can’t generate enough lift to get off the ground. Planes either need to speed up during take-off or use a longer runway.
Yikes, is it ever gonna be hot in the western United States this week. The National Weather Service has issued an excessive heat warning for Arizona, Nevada, and parts of California, where temperatures are expected to reach as high as 122 degrees F (50 C). State and local officials are asking people to take the necessary precautions.
President Donald Trump announced Thursday his decision to withdraw the US from the Paris climate accord, a sweeping step that fulfills a campaign promise while seriously dampening global efforts to curb global warming.
The facts are these: The climate of our planet is changing at a pace unlike anything seen in the natural fluctuations traced across geological records, and scientists have overwhelmingly traced this global warming trend to human activity.
