We're experiencing lovely Spring weather here and trees are blossoming everywhere.

This relatively early burst of good weather - long may it last is likely an indication of the transition from La Niña to El Niño.
What are El Niño and La Niña?
Let's read what the experts say:
El Niño and La Niña are different phases of a climate pattern that repeatedly occurs in the tropical zone of the Pacific Ocean and is known as ENSO (El Niño-Southern Oscillation). El Niño is a warming phenomenon, while La Niña is a cooling phenomenon. The two factors follow one after the other, although there are often neutral conditions between them.
During El Niño events, the Pacific surface warms, surface winds weaken and rainfall increases in the southern and eastern part of the ocean. All this causes changes in air pressure at sea level, in temperature, in rainfall and in winds, not only in the tropics, but also in many other regions of the world.
La Niña events, however, have the effect of cooling the surface of the Pacific Ocean. The consequences, like those of El Niño, can be felt all over the planet. Since September 2020, the world has been under the effects of La Niña: it has been felt, for example, in the Horn of Africa and some regions of South America in the form of strong droughts, contrasting with heavy rainfall in Southeast Asia and Australasia.
After three consecutive years dominated by La Niña, the El Niño warming phenomenon could begin to gather momentum in the Pacific in the second half of 2023. According to the WMO, there is more than a 50% chance of this happening, although, as is often the case with meteorology, this is still fraught with uncertainty.

I hope all readers are experiencing pleasant Spring weather and have the opportunity to get out and smell the roses.

I can help you there. They're called trees.

What's your standing on fascism, anti-LGBQT rights and women's freedom of choice given that you're the pope and all?
It's all in The Bible.
