The World Meteorological Organization (WMO) has reported that the world experienced its hottest week ever recorded, entering into “uncharted territory.” Preliminary data shows that the global mean temperature between July 3 and July 9 reached 17.18°C, surpassing the previous record set in 2016. Additionally, data from Japan, though yet to be confirmed by the WMO, indicates that July 7 was the hottest day on record, with a global average temperature of 17.24°C.
The WMO attributes these record-breaking temperatures partly to the onset of El Niño, which is expected to contribute to further heatwaves and extreme weather events. Professor Christopher Hewitt, the WMO director of climate services, warns that we should expect more records to fall as El Niño develops, with these impacts extending well into 2024. The WMO spokesperson, Clare Nullis, emphasizes that this news is concerning for the planet.
Global temperature averages are determined by combining satellite observations with computer model simulations, as explained by the WMO. The record temperatures in July follow the previous month of June, which exceeded the 1991-2020 average by approximately 0.5°C. This report from the European Union’s Copernicus Climate Change Service notes that June 2023 surpassed the previous June record set in 2019.
Canada is also experiencing above-normal temperatures, with records being broken in various regions. Global News chief meteorologist Anthony Farnell confirms that the Northwest Territories saw temperatures of 37.9°C, the farthest north ever recorded. These extreme temperatures can have adverse effects on the permafrost and vegetation, leading to sinkholes and the release of trapped methane in the ground.
Heat warnings were in place in six provinces and two territories in Canada on July 9, with temperatures reaching around 30°C in most areas. British Columbia experienced the breaking of six temperature records on that day. Heat domes and the displacement of heat have contributed to these persistent high temperatures, leading to extreme weather conditions in certain areas.
The high temperatures have also resulted in an increase in wildfires this year, resulting in smoky and hazy conditions in North American cities. Environment Canada warns of the health risks associated with extreme heat, including heat stroke and exhaustion. Dr. Andrew Park, the president of the Ontario Medical Association, raises concerns about the impact on low-income and vulnerable populations who lack access to cooling centers or air conditioning.
Furthermore, there is a projection of more hot days in Canada over the next 30 years, which will put additional strain on the healthcare system. Dr. Park predicts a rise in heat-related illnesses and tick-borne diseases such as Lyme disease. Meteorologist Anthony Farnell believes that more heat records will be broken throughout the summer, although the frequency might not be as extreme as the current trend.
In conclusion, the world is facing unprecedented heatwaves, with record-breaking temperatures occurring globally. These extreme weather events, influenced by factors such as El Niño, have significant implications for the environment, human health, and the healthcare system. Efforts to combat climate change and adapt to rising temperatures are crucial to mitigate these alarming trends.
