The study is based on breakthrough computer simulations of ice age onset in Earth's past climate. (2019-04-03)

Natural climate processes overshadow recent human-induced Walker circulation trends
A new study, published this week in the journal Nature Climate Change, shows that the recent intensification of the equatorial Pacific wind system, known as Walker Circulation, is unrelated to human influences and can be explained by natural processes. This result ends a long-standing debate on the drivers of an unprecedented atmospheric trend, which contributed to a three-fold acceleration of sea-level rise in the western tropical Pacific, as well as to the global warming hiatus. (2019-04-01)

We've been thinking of how ice forms in cirrus clouds all wrong
Pores in atmospheric particles allow water to condense, leading to the formation of ice crystals in humid but unsaturated air. This is a new way of thinking of ice crystal formation in clouds, particularly cirrus clouds. (2019-04-01)

Modelled climate change impact on mosquito-borne virus transmission
Mosquito-borne viruses, such as dengue, chikungunya, and Zika, already threaten over a billion people globally. A study published on March 28, 2019, in PLOS Neglected Tropical Diseases predicts that climate change and rising global temperatures will lead to both increased and new exposures to humans of diseases carried by mosquito vectors Aedes aegypti and Ae. albopictus. (2019-03-28)

Changes in onset of spring linked to more allergies across the US
Human-induced climate change is disrupting nature's calendar, including when plants bloom and the spring season starts, and new research from the University of School of Public Health suggests we're increasingly paying the price for it in the form of seasonal allergies. The study, based on over 300,000 respondents between 2002 and 2013, shows that hay fever allergies increase when the timing of spring 'greenup' changes. (2019-03-28)

Winds of change...Solar variability weakens the Walker cell
An international team of researchers has found robust evidence for signatures of the 11-year sunspot cycle in the tropical Pacific. They analyzed historical time series of pressure, surface winds, and precipitation with focus on the Walker Circulation -- a vast system of atmospheric flow in the tropical Pacific region that affects patterns of tropical rainfall. They have revealed that during periods of increased solar irradiance, the trade winds weaken and the Walker circulation shifts eastwards. (2019-03-28)

Rivers raged on Mars late into its history
A new study by University of Chicago scientists catalogued these rivers to conclude that significant river runoff persisted on Mars later into its history than previously thought. According to the study, published March 27 in Science Advances, the runoff was intense -- rivers on Mars were wider than those on Earth today -- and occurred at hundreds of locations on the red planet. (2019-03-27)
