The World Meteorological Organization identifies the current spell of extreme heat as a new climate baseline, a development they call the new normal. This framing came in a formal statement on the organization’s site, reflecting a shift that experts expect to persist across years to come.
Meteorologists point out that the July to August period in 2023 featured heat and drying conditions well beyond typical patterns, yet they are not surprising in the context of recent climate data. The consensus is clear: the heat is intensifying and extending in time, signaling a long term trend rather than a short term anomaly.
Climate scientists emphasize a strong link between rising extreme temperatures and human driven climate change. A prominent expert, Alvaro Silva, notes there is a high degree of confidence that human activities are the main driver behind the increased frequency and severity of heat waves and heavy rainfall events.
Data from July 2023 shows it dominating long term heat records. Simultaneously, multiple meteorological services across parts of Europe reported a pronounced heat wave during the third week of August, underscoring a continental scale shift in temperature patterns.
The WMO called on authorities and communities to listen to warnings from meteorological and hydrological services, using available forecasts and early warning systems to plan and protect lives, property, and food security. The message is clear: adaptive planning, preparedness, and shared data are essential steps as conditions continue to evolve.
In related discussions about weather and climate, forecasts of cooler periods sometimes emerge, sparking headlines about relief from heat. Analysts remind the public that such shifts can be temporary within a broader trend that remains skewed toward higher baseline temperatures and more intense extremes in coming years.
Experts also stress that understanding heat waves goes beyond daily highs. They involve humidity levels, soil moisture, and regional influences such as urban heat islands, which can amplify perceived heat. Preparedness includes strengthening infrastructure, ensuring access to cooling, and supporting vulnerable communities as part of a comprehensive climate adaptation strategy. Ongoing observations and research continue to refine projections and inform policy decisions for the North American region and beyond. [WMO attribution]
