A new study projects the spread of the destructive southern pine beetle through much of the northern United States and southern Canada. Darker colors here represent infestations in successively later decades. (Lesk et al., 2017)

Climate May Quickly Drive Forest-Eating Beetles North, Says Study

Over the next few decades, global warming-related rises in winter temperatures could significantly extend the range of the southern pine beetle, one of the world’s most aggressive tree-killing insects, through much of the northern United States and southern Canada, says a new study.

Women may Bear the Brunt of Climate Change’s Impacts

The effects of climate change aren’t equitable from a gender perspective; women are generally disproportionately impacted by climate change in comparison to their male counterparts.

The Gendered Role of Climate Change

Globally, women are disproportionately affected by rising seas, too much or too little rainfall, and storm surges, all as a result of a changing climate.

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.

Africa's Sahel region could suddenly get far more rainfall as global warming proceeds, says a new study. Here, farmers in Mali, one of the countries potentially affected, harvest okra. (Francesco Fiondella/International Research Institute for Climate and Society)

Warming Climate Could Abruptly Increase Rain in Africa’s Sahel

Climate change could turn one of Africa’s driest regions wet, according to a new study. Scientists have found evidence in computer simulations for a possible abrupt change in the Sahel, a region long characterized by aridity and political instability. In the study, just published in the journal Earth System Dynamics, the authors detected a self-amplifying… read more

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

Upsala Glacier, Argentina, where scientists collected glacial dust samples. When glaciers move across bedrock, they scrape against it (see glacial grooves in the foreground), and grind it into smaller particles, which may then get blown out to sea. The turquoise blue water of the lake in the background is caused by the milkiness of the fine glacial dust suspended in it.  (Elizabeth Shoenfelt)

Iron Chemistry Matters for Ocean Carbon Uptake

An interdisciplinary team of scientists has discovered that, contrary to general scientific belief, iron in nondissolved particle form can stimulate phytoplankton growth, and that the chemical form that particulate iron takes is critical to ocean photosynthesis.

IRI Unveils Its New Generation of Climate Forecasts

This spring, IRI implemented a new methodology for seasonal temperature and precipitation forecasts. We asked Simon Mason, Andrew Robertson and Tony Barnston, senior climate scientists who lead the development and tailoring of IRI’s forecasts, to answer some fundamental questions about the new forecast.

As rain belts shift due to uneven heating across the globe, wet areas will become wetter and dryer areas dryer, a new study affirms. Here, visitors cross a Panama farm field in a winter downpour. (Kevin Krajick/Earth Institute)

In a Warmer World, Expect the Wet to Get Wetter, and the Dry, Drier

As the world warms due to human-induced climate change, many scientists have been projecting that global rainfall patterns will shift. In the latest such study, two leading researchers map out how seasonal shifts may affect water resources across the planet.
