Climate change is forcing farmers to migrate from Central America

In Central America's Dry Corridor, a historically drought-prone region that stretches from Mexico to Panama and is home to 10.5 million people, climate change is producing longer and more frequent dry spells and forcing a growing number of farmers to attempt to migrate to the U.S., according to FERN's latest story, published with The Weather Channel.

With or without El Niño, 2017 is at the top of the list for hottest years

According to NASA data, 2017 was the second-hottest year on record, or the hottest year without an El Niño weather pattern, which drives up temperatures in the short term.

Forest fires a leading factor in loss of tree cover worldwide

An area the size of New Zealand, some 29.7 million hectares (73.4 million acres), was stripped of tree cover during 2016, says data on Global Forest Watch, an increase of 51 percent from the previous year. "Forest fires seem to be a primary cause for this year's spike, including dramatic fire-related degradation in Brazil," wrote two World Resources Institute analysts in a blog.

The food chain is looking threadbare, say scientists studying dolphins

The food chain off the coast of California is starting too look shorter and less diverse thanks to environmental events like El Niño and potentially climate change, say scientists who tracked the diets of dolphins.

2016 temperatures, sea and CO2 levels highest on record

With temperatures approximately 1 degree Fahrenheit hotter than the average temperature from 1981 to 2010, 2016 was the hottest year on record, according to a report published by the American Meteorological Society. Last year was the third year in a row for record heat in the U.S.

Monsoon season in India may escape El Niño’s touch

The monsoon rains that are the lifeblood of India's farmers may be unaffected by forecasts of an El Niño weather pattern at mid-year, a top weather official told Reuters. The rains usually arrive around June 1 at Kerala, a state at the southern tip of India, the second-most populous nation in the world, and retreat by September from Rajastan, which borders Pakistan in northern India, some 2,000 kilometers away.

Global food insecurity increases due to armed conflict

Civil conflicts and their consequences, including refugees needing food in neighboring countries, are a factor in 21 of the 39 countries that need food assistance, says the UN Food and Agriculture Organization in a quarterly report. Warfare in Syria, Yemen, Iraq, Afghanistan and Nigeria has disrupted food supplies for at least 40 million people, it said.

Land-clearing a factor in fires that led to 100,000 deaths

More than 100,000 people died prematurely because of smoke and haze created by vast forest fires, mainly in Indonesia, last year, said the New York Times, pointing to research by two U.S. universities. The blazes destroyed more than 10,000 square miles of forests and began with fires intended "to clear land for palm oil plantations and other uses," said the newspaper.

Below-normal cereal harvest in Africa due to El Niño drought

Africa accounts for 28 of the 36 countries worldwide that need food aid, says the FAO in its quarterly Crop Prospects and Food Situation report. Drought reduced harvests in North Africa and in southern Africa, more than offsetting improvements in East and West Africa and pulling the continent's grain output to a below-normal level.

Chances of La Niña weather pattern plummet

NOAA has shelved its La Niña watch because its forecasters see little prospect for the weather pattern, somewhat of a mirror to the better-known El Niño, for the next six months. In June, La Niña chances were 75 percent but they are now 40 percent because air and water temperatures in the southern Pacific Ocean are relatively neutral between the two weather patterns.
