The year 2021 was a rather cranky one for our team! For one, quite some research was cranked out - i.e. published - by team members and for another, a particular Cranky Uncle started to make the rounds throughout the year.  As in previous recaps, this one is divided into several sections:

This is a re-post from Yale Climate Connections by Bob Henson

The El Niño-Southern Oscillation, which has a huge influence on global weather patterns, isn't behaving as computer models predicted. That's puzzling scientists.

ENSO Blog: How the Pattern of Trends Across the Tropical Pacific Ocean Is Critical for Understanding the Future Climate and Changes in El Niño and La Niña

The causes of climate change are typically attributed to greenhouse gases like carbon dioxide or methane that form homogeneous mixtures spread evenly across the globe, which lead to relatively uniform and well-understood effects, namely, the warming of the planet. But scientists are increasingly realising that greenhouse gases only tell part of the story. Another major […]

Of the nine critical planetary boundaries that humanity is transgressing, climate change is the best known and understood, while atmospheric aerosol pollution may be the least, but aerosols are already having climate impacts and polluting Earth’s skies, killing millions.

Read time:   A new Yale study suggests that aerosols in the atmosphere may be temporarily holding down ocean temperatures in the eastern equatorial Pacific. The findings, published in the journal Nature Climate Change, are an indication that the surprisingly modest warming observed in the tropical Pacific in recent decades may be short-lived, with more dramatic changes yet to come. The results also may help climate scientists make better predictions for how global warming will affect weat...
