The thirteenth tropical cyclone of the northwestern Pacific Ocean typhoon season has formed and NASA's Terra satellite obtained a visible-light image of the storm revealing that it's already battling wind shear.

Cornell atmospheric scientists have developed the first-of-its-kind, high-resolution Caribbean drought atlas, with data going back to 1950. Concurrently, the researchers confirmed the region’s 2013-16 drought was the most severe in 66 years due to consistently higher temperatures – a hint that climate change is to blame.

There could be some good news on the horizon as scientists try to understand the effects and processes related to climate change.

The next mega-droughts and subsequent active wildfire seasons for the western U.S. might be predictable a full year in advance, extending well beyond the current seasonal forecast and helping segments of the economy related to agriculture, water management and forestry.

As climate change brings new pressures to bear on wildlife, species must “move, adapt, acclimate, or die.” Erik Beever and colleagues review the literature on acclimation through behavioral flexibility, identifying patterns in examples from invertebrates, amphibians, reptiles, birds, mammals, and fishes, in the cover article for the August issue of the Ecological Society of America’s (ESA) journal Frontiers in Ecology and the Environment. The authors focus on the American pika (Ochotona princeps) as a case study in behavioral adaptation.

The DST-NRF Centre of Excellence for Palaeoscience funded researchers based in the School of Geography, Archaeology and Environmental Studies and in the Evolutionary Studies Institute of the University of the Witwatersrand have used fossil pollen records to solve an on-going debate regarding invasive plant species in eastern Lesotho.

The El Niño Southern Oscillation (ENSO) has been shown, for the first time, to play a role in increased rainfall and storms along the Red Sea and surrounding regions.

A new study from the University of North Carolina at Chapel Hill estimates that future climate change, if left unaddressed, is expected to cause roughly 60,000 deaths globally in the year 2030 and 260,000 deaths in 2100 due to climate change’s effect on global air pollution.

The study, to appear in the July 31 advance online issue of Nature Climate Change, adds to growing evidence that the overall health effects of a changing climate are likely to be overwhelmingly negative. It is also the most comprehensive study yet on how climate change will affect health via air pollution, since it makes use of results from several of the world’s top climate change modeling groups.

The aardvark, a highlight for anyone on a game-viewing African safari, will become increasingly rare as the world warms and dries, and the consequences go well beyond a decline in aardvark safari encounters.

The Intertropical Convergence Zone (ITCZ), also known as the doldrums, is one of the dramatic features of Earth’s climate system. Prominent enough to be seen from space, the ITCZ appears in satellite images as a band of bright clouds around the tropics. Here, moist warm air accumulates in this atmospheric region near the equator, where the ocean and atmosphere heavily interact. Intense solar radiation and calm, warm ocean waters produce an area of high humidity, ascending air, and rainfall, which is fed by converging trade winds from the Northern and Southern Hemispheres. The convected air forms clusters of thunderstorms characteristic of the ITCZ, releasing heat before moving away from the ITCZ — toward the poles — cooling and descending in the subtropics. This circulation completes the Hadley cells of the ITCZ, which play an important role in balancing Earth’s energy budget — transporting energy between the hemispheres and away from the equator.
