Two Samoas hit with extreme temperatures

American Samoa and the Independent State of Samoa are both experiencing historically high number of ‘hot days’ this decade according to the latest report by the Pacific Islands Climate Regional Assessment team.
The Scientists found that for American Samoa the number of hot days has increased from 9 in the 1960s to 22 days per year in 2020.
Hot days are described in the report as 90°F and above. The meteorological station in Apia in the Independent State of Samoa records that maximum temperatures have increased more in the wet seasons in November-April than in drier seasons in May to October. “Surface air temperature is expected to continue to increase this century,” the report states.
An expected rise to 1.3°C degrees Fahrenheit by 2050 is noted in the report.
In the records of cool nights, the report highlights that cool nights have decreased from 85 nights to just 4 nights per year in American Samoa. The impacts of climate change haven’t been spread evenly around our planet and they won’t be in the future, either. Temperatures increase at different speeds everywhere, with warming generally higher over land areas than oceans. 

According to the Intergovernmental Panel on Climate Change extreme temperatures on land are projected to warm more than the global average surface temperature, with substantial differences from place to place. The IPCC notes that most land regions will see more hot days, especially in the tropics. At 1.5 degrees Celsius warming, about 14 percent of Earth’s population will be exposed to severe heatwaves at least once every five years, while at 2 degrees warming that number jumps to 37 percent. Extreme heatwaves will become widespread at 1.5 degrees Celsius warming.
