due to a massive heat dome that has been affecting the country for weeks. Now this system has extended northwards into the south US, causing extreme heat across a large region.A heat dome is not a clearly defined scientific term but is used by many weather forecasters. The American Meteorological Societyas an “exceptionally hot air mass that develops when high pressure aloft prevents warm air below from rising”.
There is also some evidence that the intensity of heat domes is outpacing the warming trend, suggesting that warming is amplifying their intensity . “The intensities of hot extremes associated with… heat dome-like atmospheric circulations increase faster than background global warming in both historical change and future projection,” statesAnalysis finds the carbon footprint of cultivated meat is likely to be higher than beef if current production methods are scaled up because they are still highly energy-intensive
