Xiaohan, as the fifth solar term of winter, usually marks the arrival of the coldest period of the year. However, this year's Xiaohan seems to be different from previous years, and its early arrival is a wake-up call for us to change the tide.
According to meteorological records, this year's Xiaohan came a few days earlier than usual, breaking the usual weather pattern. This phenomenon is not accidental, but a concrete manifestation of global climate change. The continued rise in global temperatures, the melting of polar glaciers, and the frequency of extreme weather events provide us with clear evidence of climate change.
"It's a little cold and a big cold, frozen into a ball. ": The small cold and the big cold are the coldest solar terms in winter, when the temperature is extremely low and the earth is frozen, and people need to take measures to protect themselves from the cold.
"Xiaohan for three or nine days, take good anti-freeze. It is the coldest time of the year, and people need to pay special attention to cold and keep warm to prevent frostbite.
"It doesn't snow in the small cold and big cold, and the fields crack in the small summer and big summer. This agricultural proverb shows that if there is no snow during the Xiaohan and Dahan solar terms, then the weather will be dry and rainless during the Xiaoxia and Da Xia solar terms, resulting in a lack of water and reduced crop yields.
"Xiaohan and Dahan killed pigs for the New Year. ": During the small cold and the big cold, some places have the Xi of killing pigs to prepare for the New Year. This is because the temperature is lower at this time, and the pork is not perishable and can be stored for a longer time.
"The little cold and the big cold turn into ice. ": Xiaohan and Dahan are the coldest solar terms in winter, when the temperature is extremely low and the water surface is frozen, and people can skate and play.
These agricultural proverbs are the summary of people's long-term production practice experience and the crystallization of wisdom. They have important reference value for guiding people in agricultural production, disaster prevention and mitigation, and weather prediction. At the same time, these agricultural proverbs are also an important part of traditional culture, reflecting people's cognition and exploration of the laws of nature.
For our region, the cold and warmth of the small cold season are intertwined, creating a unique climatic phenomenon. Although there are occasional brief periods of warm weather, the cold is still dominant during this period overall. Such a climate pattern makes it necessary to pay special attention to the changes in the weather and prepare for the cold and warmth in advance.
At the same time, this interweaving of cold and warm seasons also presents an important warning that future climate change trends may be more complex and difficult to predict. In the context of global warming, the frequency and intensity of extreme weather events are likely to increase, which brings unprecedented challenges to many areas such as agricultural production, transportation, urban planning and public health.
In the face of this challenge, we need to take a series of measures to combat climate change. The government should increase investment in climate change research to improve the accuracy of climate predictions, and enterprises and individuals should also improve their own climate adaptability and make their own contributions to mitigating global warming by taking measures such as energy conservation, emission reduction, and green travel.
In general, "Xiaohan came early, Jiujiu wears single clothes", this year's Xiaohan is indeed unusual. It not only indicates that we will face more complex climate challenges, but also reminds us that we must prepare early to jointly address the challenges of global climate change. Only through global cooperation and efforts can we better adapt to future climate change and create a better future.
