A new temperature dataset extending back to 1781 suggests the Earth may have warmed more than previously thought before 1850, indicating that human influence on climate could be slightly greater than earlier estimates, but the implications for current climate goals remain complex.
Earth's average temperature reached an unofficial record high of 17.18 degrees Celsius (62.9 degrees Fahrenheit) on Wednesday, matching the previous day's record, according to the University of Maine's Climate Reanalyzer. While not an official government record, the figures indicate the unprecedented territory of climate change. High-temperature records were also broken in Quebec and Peru this week. The exceptionally mild winter in the Antarctic contributed to the records, with parts of the continent and nearby ocean experiencing temperatures 10-20 degrees Celsius (18-36 degrees Fahrenheit) warmer than average. Scientists warn that global warming is pushing us into a hotter future, with more frequent and intense heat waves disrupting life worldwide.
Central Florida experienced its hottest days of the year on Monday and Tuesday, with temperatures reaching 62.9°F (17.18°C), breaking the previous record set the day before. This two-day heatwave is part of a global trend of rising temperatures, exacerbated by a strengthening El Niño. Central Florida has also seen its warmest first half of the year ever recorded. As the summer continues, it is important to be aware of the signs and symptoms of heat-related illnesses.
Solar storms are causing Earth's thermosphere to experience a significant temperature increase, the highest it's been in two decades, and this warming trend may continue over the next few years as the sun's activity intensifies. This could have potentially negative implications for Earth-orbiting satellites, as the thermosphere expands as it warms, resulting in increased aerodynamic drag on all satellites and on space debris. Developing strategies to predict space weather more accurately and implementing contingency plans for satellite repositioning is essential for safeguarding valuable space assets.
The ozone layer in the Earth's upper atmosphere is critical for blocking ultraviolet radiation from the Sun and has a warming effect on our surface temperatures, on average increasing the surface temperature of the Earth by about 3.5 Kelvin. If the ozone layer were to disappear, whether through human or some other means, this would have a catastrophic effect on our climate, including a cooling of the upper stratosphere, destabilization of the atmosphere, and drastic consequences for seasonal weather patterns at all latitudes.
