Record-shattering March temperatures in Western North America virtually impossible without climate change
The #heatwave poses a significant public health threat, particularly given its timing early in the season. The persistent #HeatDome is creating stable atmospheric conditions, suppressing cloud formation and precipitation, while allowing temperatures to climb, thus expected to cause persistent #heat. #ExtremeHeat is the leading cause of weather-related fatalities in the US. Limited overnight cooling and the lack of air-conditioning is expected to add to the heat stress, particularly for vulnerable populations in these parts who are not acclimatised to the heat, including tourists from cooler countries (CNN, 17 March 2026). This heat dome is breaking records for this time of the year, and is in some ways comparable to the persistent system that caused the 2021 Pacific Northwest (PNW) Heatwave. The PNW event occurred later in the year, in June, with temperatures of up to 48.9℃ (120℉) causing hundreds of fatalities (BBC, 17 March 2026).

Increasingly severe rainstorms put people and structures built on floodplains at risk
Since 16 January, nine named storms have battered the western #Mediterranean, with #Spain, #Portugal and #Morocco hardest hit.
In Spain, #flooding and infrastructure damage from heavy winds forced over 12,400 evacuations, affected 115,000 people in 19 villages in the Sierra de Cádiz, and led the Spanish Government to commit more than €7 billion in aid, with an additional €1.78 billion from the #Andalusian regional government.
Portugal recorded six fatalities during #Storm Kristin, with winds up to 202 km/h leaving one million people without electricity and causing widespread structural damage, and the Portuguese Government has already committed to supporting the reconstruction with a package of €3.5 billion.
In northern Morocco, flooding caused 43 deaths, displaced 300,000 people and inundated 110,000 homes, prompting a €280 million recovery plan.
While the high winds were exceptional and caused part of the damages, the most severe impacts are due to the heavy rain accompanying each storm that led to flooding in various regions. Later in the season the increasingly saturated soils also contributed to the flooding.

Why is #ClimateChange causing ‘record-shattering’ extreme heat?
Amid the disaster, temperatures in #Lytton was smashing the previous record for the country by 4.6C.
Climate scientists studying the #heatwave were left stunned by the record-shattering temperatures.
“Within our knowledge, this [heatwave] is basically impossible,” the late pioneering #ExtremeWeather scientist, Dr Jan van Oldenborgh, told a press conference at the time...https://www.carbonbrief.org/explainer-why-is-climate-change-causing-record-shattering-extreme-heat/

Heavy rain that flooded northeast Aotearoa #NewZealand is now more common on warmer planet
Based on historical weather station data, the scientists found that heavy rainfall events, like those seen during #CycloneGabrielle, now produce around 30% more rain than before humans warmed the planet.
