Summer is coming. In the north. For real. Unless we take significant steps to save the planet from climate change. A new study suggests that by the year 2100, the impact of climate change could be such that summers could last about six months in the Northern Hemisphere. This could have a significant impact on the environment, as well as the living conditions for humans and other animals.
The paper, now published in the Geophysical Research Letters journal, studied everyday climate data from 1952 to 2011. They sought to measure changes in the onset and duration of the four seasons in the northern hemisphere. Established climate change models were used to determine how seasons may shift in the future.
The study found that between the years 1952 to 2011, summer grew and winters shrank. On average, the former went from 78 to 95 days in a year, whereas winter days were down from 76 to 73 days. The most impacted regions were the Tibetan plateau and the Mediterranean.
Despite being so cold, February 2021 was still 0.06°C above the 1991-2020 global average and 0.26°C above the 1981-2010 global average.
If climate change continues to accelerate without any mitigation efforts, over the next 50 years, the planet may experience winters less than two months, and even shorter springs and autumns. Monsoon and rainfall patterns are set to be affected as well.
We are currently experiencing various events around the world that point towards this future. Unseasonal rainfall, flooding, snowstorms, and such are phenomenons that would only become more commonly occurring in a future created by climate change. “A hotter and longer summer will suffer more frequent and intensified high-temperature events – heatwaves and wildfires,” said Congwen Zhu, a monsoon researcher at the State Key Laboratory of Severe Weather and Institute of Climate System, Chinese Academy of Meteorological Sciences, Beijing. He was not involved in this study.
Changes in temperatures, seasons, and overall weather conditions also heavily impact agriculture and vegetation. It is set to heavily disrupt ecological communities.
I am a simple writer who wishes to use her skill to create more awareness about the planet that offers us life.
