Kevin Krajick is the Earth Institute's senior editor for science news. A native of upstate New York, he started in journalism at his high-school newspaper in the late 1960s. He has since reported from all 50 U.S. states and 30-some countries, covering science, law, immigration and other areas. His work has appeared in Newsweek, National Geographic, The New Yorker, Science, Smithsonian and many other publications. He was a 1981 finalist for the National Magazine Award for Public Service for reporting on organized crime links to the toxic waste-disposal industry. He is two-time winner of the American Geophysical Union's Walter Sullivan Award, for his coverage of the earth sciences. His 2001 book "Barren Lands" is the true account of how diamond mines were discovered in Canada's far north. He lives in New York City with his wife and two teen daughters.

When People Must Make Way for Nature

It is the black before dawn at the gate to the Kanha Tiger Reserve, in the highlands of central India. The still air carries a dank, penetrating chill. But it is hardly quiet. A buzzing line of tourists is forming at the ticket booth, peddlers are pouring steaming cups of tea.  Groups of green-uniformed rangers chat… read more

Photo Essay: When People Must Make Way for Nature

The forested Kanha Tiger Reserve, in the highlands of central India, is home to an abundance of rare wildlife. It also used to be home to thousands of people—that is, until they were moved out by the government to make way for endangered creatures.

Due to warming climate, some aircraft may soon have a hard time getting off the ground in the heat of the day. Here, a jet takes off from the Canary Islands. (Bruno Gelger, via flickr)

Surging Heat May Limit Aircraft Takeoffs Globally

Rising temperatures due to global warming will make it harder for many aircraft around the world to take off in coming decades, says a new study. During the hottest parts of the day, 10 to 30 percent of fully loaded planes may have to remove some fuel, cargo or passengers, or else wait for cooler hours to fly.

Fueled by Melting Glaciers, Algae Bloom Off Greenland

Iron particles catching a ride on glacial meltwater washed out to sea are likely fueling a recently discovered summer algal bloom off the southern coast of Greenland, according to a new study. Microalgae, also known as phytoplankton, are plant-like marine microorganisms that form the base of the food web in many parts of the ocean…. read more

Scientists have discovered that seasonally flowing streams fringe much of Antarctica’s ice. Each red ‘X’ represents a separate drainage. Up to now, such features were thought to exist mainly on the far northerly Antarctic Peninsula (upper left). Their widespread presence signals that the ice may be more vulnerable to melting than previously thought. (Adapted from Kingslake et al., Nature 2017)

Water Is Streaming Across Antarctica

In the first such continent-wide survey, scientists have found extensive drainages of meltwater flowing over parts of Antarctica’s ice during the brief summer. Many of the newly mapped drainages are not new, but the fact they exist at all is significant; they appear to proliferate with small upswings in temperature, so warming projected for this century could quickly magnify their influence on sea level.

Scientists Say They Now Know Why Antarctic Meltwater Stays Below Ocean Surface

Up to now, it has been a mystery why much of the fresh water resulting from the melting of Antarctic ice shelves ends up in the depths instead of floating above saltier, denser ocean waters. Scientists working along one major ice shelf believe they have found the answer.

Photo Essay: Where the Trees Meet the Tundra

Due to warming climate and increasing human exploitation, far northern forests and the tundra beyond are undergoing rapid changes. In northern Alaska, scientists from Columbia University’s Lamont-Doherty Earth Observatory and other institutions are studying the responses of trees at the very edge of their range.
