    Does doom and gloom convince anyone about climate change?

    A couple of weeks ago, an article in New York magazine laid out a horrific scenario of global warming. The photo at the top summed up the tone: A fossilized human skull, jaw gaping beneath aviator sunglasses, hovered over a caption warning that people could be “cooked to death from both inside and out” in a hotter climate.

    If that’s not doom and gloom, I don’t know what is. Yet despite...

    Rising temps may mean fewer passengers on airplane flights

    As if air travel weren’t annoying enough, new research suggests that global warming will force planes to carry fewer passengers to get off the ground. While a little more legroom might sound good, it could make flying more expensive. 

    Researchers examined the impact of rising temperatures on five types of commercial planes flying out of 19 of the world’s busiest airports. In the coming...

    Delaware-sized iceberg breaks off Antarctic ice shelf

    With a final rip, an iceberg roughly the size of Delaware has broken off Antarctica’s Larsen C ice shelf. Anticipated for weeks, the fracture is one of the largest calving events ever recorded.

    On July 12, satellite images confirmed a nearly 5,800-square-kilometer, 1-trillion-metric-ton chunk of ice, equivalent to 12 percent of Larsen C’s total area, split from the ice shelf. “[We] have...

    Climate change could exacerbate economic inequalities in the U.S.

    Climate change may make the rich richer and the poor poorer in the United States.

    Counties in the South face a higher risk of economic downturn due to climate change than their northern counterparts, a new computer simulation predicts. Because southern counties generally host poorer populations, the new findings, reported in the June 30 Science, suggest that climate change will worsen...

    Battering storms caused Antarctic sea ice to shrink at record pace

    View the video

    Unusually severe storms in 2016 wrought the quickest meltdown of Antarctic sea ice ever seen during a Southern Hemisphere spring. This could explain why Antarctica’s sea ice extent hit a record low earlier this year.

    Satellite images show that the extent of Antarctic sea ice decreased by an average of 75,000 square kilometers — almost the area of South...

    Readers question climate’s freshwater effects

    Water woes

    A recent survey of lakes around the globe found that from 1985 to 2009, most warmed while only several cooled, Alexandra Witze reported in “In hot water” (SN: 5/13/17, p. 18). Rising temperatures have consequences for every part of a lake’s food web, from algae to walleye to freshwater seals.

    “This article indicates that no pattern could be found to predict which lakes would...

    Climate change might help pests resist corn’s genetic weapon

    Climate change might be great news for pests looking to munch on genetically modified crops, researchers propose.

    In particular, researchers analyzed 21 years of data from Maryland cornfields and suggest that rising temperatures might help corn earworms (Helicoverpa zea) develop resistance faster to a widespread genetically built-in crop protection.

    Some commercial varieties of...

    Antarctica’s Larsen C ice shelf is within days of completely cracking

    The rift in Antarctica’s Larsen C ice shelf continues to rip. Researchers from Project MIDAS, which tracks the effects of a warming climate on the ice shelf, report that the crack grew 17 kilometers between May 25 and May 31.

    The crack has now turned toward the water and is within 13 kilometers of the edge of the shelf. Within days, the crack could reach the edge. When that happens, one...

    U.S. will withdraw from climate pact, Trump announces

    President Donald Trump announced on June 1 that the United States will pull out of the Paris climate accord.

    In signing the 2015 Paris agreement, the United States, along with 194 other countries, pledged to curb greenhouse gas emissions to combat global warming. But Trump — who has called climate change a “hoax” despite scientific evidence to the contrary — promised during his campaign...

    Readers puzzled by proton's properties

    Proton puzzler

    Uncertainty over the proton’s size, spin and life span could have physicists rethinking standard notions about matter and the universe, Emily Conover reported in “The proton puzzle” (SN: 4/29/17, p. 22).

    Readers wondered about the diameter (or size) of the proton, which has three fundamental particles called quarks rattling around inside. “Still scratching my head over how...
