Spring is the season of change. It is a transitional period between cold winter cold and summer heat.
But the spring itself also passes through a transformation of a kind. Like everything is affected by climate change, the spring is different from what it was. So, while we start another season of warming, emerging flowers and cooling rains, here is a look at how spring changes over the past century.
It started earlier
Of course, the official start of the seven in the calendar did not move, but the green spaces that we link to the season will soon arrive from what it was.
The climate change has disrupted the natural rhythms of the seasons. Although the effects differ from year to year, winter has become warmer and shorter. This means that the cold that prevents plants from prosperity is less dense and fades earlier.
Scientists at the Environmental Protection Agency have found a way to determine this change. Using life cycles records in honey and men factories from all over the country dating back to the mid -twentieth century, they have laid a mark when these plants begin to show liar signs of winter (what they call the first paper) and when they germinate in flowers (called the first flowering).
In most countries, First Leaf and First Bloom Speak earlier than today than they used to. How much spring early is a little different. In some parts of the West Coast and Central Plains, First Bloom will come for several weeks – or even a full month – earlier. On the other hand, the flowers later germinate in certain areas of the upper Middle West.
The most suitable conditions for plants also mean more challenges for allergic patients. On average, the plants begin to release the pollen about two weeks after they appear from their winter stillness. The previous start means that the spring sensitivity season has become “longer and more intense”, according to the Environmental Protection Agency.
It is getting hotter
Along with autumn, spring is often known as the “shoulder season” due to moderate temperatures for the winter and summer. Although this is still true – especially with the emergence of the maximum degrees of other seasons more intense – the spring is not moderate as it was for most of the country.
The average national temperature for every months of the spring has increased in several degrees since the middle of the last century. The weather varies from year to year, but the general trend is clear. The changes are particularly clear in the early stages of the season.
How hot the most hot things are different by site. Comparing the average spring temperatures from 1950 to 2024 shots the extent to which things change significantly. The most important shift in states such as Michigan and Minnesota has been found, as temperatures rise by more than 13 degrees. Only two states, California and Arizona, witnessed that their average temperatures decrease, and only with a slight amount.
It becomes more moisture
Warm spring rains are one of the wedding signing weddings. On the national level, climate change meant more bathing in the spring than in the past.
But those groups at the country level hardly tell the full story. The deepest diving in data shows that spring rains have become more concentrated in places that have already seen the most precipitation. Spring rains have decreased dramatically in the southwest of the United States and the Gulf states, making drought in the most severe arid in the country. These cuts are compensated, then some, by increasing rain in the Middle West and the Northwest Pacific.
Where the average of rain changes between the first half of the twentieth century and today.
The spring weather for this year is expected to fit with these patterns. The National Administration of Oceanic and Air Country released New expectations During the next three months on Thursday, which expect higher temperatures than abnormal for most of the country, along with lower rains in the southwest and more parts of the Middle West.
