El Niño's chang­ing pat­terns: Human influ­ence on nat­u­ral vari­abil­ity

Two new studies suggest that human-induced climate change is now a dominant factor in shaping El Niño patterns. The research reveals that the 'Walker switch' mechanism, triggered by changes in solar radiation, instigates swift adjustments in sea-surface temperatures, influencing climate patterns globally.

Climate change: Atlantic hurricanes twice as likely to strengthen from weak to major intensity in 24 hours

A recent study found that Atlantic hurricanes are now twice as likely to strengthen from weak to major intensity in a 24-hour period than between 1970 and 1990. The study suggests that warmer oceans under climate change are driving this increase, with the fastest intensification typically occurring over warm sea surface temperatures.
