The entire global water cycle is changing drastically!

The impact of human activities on the environment is undeniable, and in recent times, it's the global water cycle that's feeling the strain. We've seen some alarming shifts that have raised eyebrows among environmentally conscious individuals.

In 2022, an unusual trend was observed in the water cycle, marked by significant and unexpected changes. The year represented the third consecutive La Niña year, leading to excessive rainfall in Southeast Asia and Australia, while concurrently causing extreme dry spells in other areas of the Pacific.

These patterns, although predicted, leave us questioning the underlying cause of such drastic changes. It seems these events are not mere happenstances, but rather, harbingers of nature's distress signals. 

Let's delve deeper into the water cycle's transformation in 2022.

The Altering Water Cycle

The global water cycle is undeniably undergoing changes. The increasing heat and dryness of the worldwide climate lead to the rapid development of droughts and heightened risk of wildfires.

The Year 2022: A Synopsis 

The third consecutive La Niña year in 2022 greatly impacted global weather patterns. A La Niña, characterized by cooler-than-normal sea surface temperatures in the central and eastern tropical Pacific and warmer conditions in the western Pacific, influences trade winds to bring rainfall to Southeast Asia and Australia.

The conjunction of the La Niña phenomenon and warm waters in the northern Indian Ocean in 2022 resulted in extensive flooding across a broad swath from Iran to New Zealand. The impact was particularly devastating in Pakistan, where severe flooding displaced approximately 8 million people. Australia also witnessed numerous intense flood events throughout the year.

Contrastingly, the western United States and central South America were grappling with a multi-year drought, causing historically low lake levels. The ongoing drought also wreaked havoc on crops and escalated the humanitarian crisis in the Horn of Africa.

 Rainfall Patterns Undergoing Change

While global rainfall averages remain consistent, some regions are experiencing concerning trends. Monsoon regions from India to Northern Australia are getting wetter, while parts of the Americas and Africa are progressively drying up. 

Rainfall intensity over short periods is increasing in many areas, leading to disastrous flash floods and landslides, significantly impacting populated regions.

A Growingly Hotter and Drier World

Global air temperatures are on an upward trend. Heatwaves are becoming more severe and prolonged. These high temperatures, in addition to being disastrous in themselves, also affect the water cycle by causing "flash droughts". 

The air is not only getting warmer but also drier, almost universally. This increased aridity puts pressure on water resources as people, crops, and ecosystems require more water to thrive. 

A Glimpse into the Future

The influence of La Niña seems to be receding, with a possible switch to an El Niño later this year. This could bring relief to drought-affected regions but also potentially lead to heatwaves and bushfires in places like Australia.

It's uncertain whether the triple La Niña is a result of climate change or a statistical anomaly. If La Niña or El Niño becomes more prolonged in the future, we might encounter deeper droughts and more severe floods.

The reduction of greenhouse gas emissions by humanity will shape our planet's future. Until then, we can expect the breaking of new records in heatwaves, downpours, flash droughts, wildfires, and ice melts. It's a stark reminder for us to pay attention to these warning signs and prepare for a challenging future.
