La Niña heads for rare "triple dip," dampening global temperatures

La Niña, which is characterized by cooler than average sea surface temperatures in the equatorial Pacific Ocean, has repercussions for the Atlantic hurricane season.

The current La Niña began back in the late summer and early fall of 2020, and it has reached an intensity that ranks it "among the strongest springtime La Niñas in the historical record dating back to 1950,".

With each week that La Niña remains, the less likely it becomes that 2022 will set a new global temperature record. However, La Niña has still other consequences and is likely exacerbating the drought in the Southwest.

The environment and the covid 19 pandemic

he speed and effects of climate change create a crisis even more severe than the pandemic. The current trajectory of development has jeopardized the balance of the ecological system that supports it.

Due to the growing influence of humans on nature, biogeochemical cycles have been drastically altered and biodiversity has been reduced at a threatening rate. Causes include rising global temperatures. The Latin American and Caribbean region is mainly affected by climate change.

As a result of the pandemic, industrial activities, the number of flights and mass events have been reduced, resulting in positive but temporary impacts on the environment; however, there have also been other negative impacts such as the increased use of single-use plastics and the expansion of household and hospital waste.

The pandemic brings to the table the complex interaction between the systems of planet Earth and the current structure of social, economic and environmental policies.

What changed with the epidemic?

Since December 31, 2019 the world has gone from predictions of declining economic growth/recession to being faced with the first global economic contraction since the 1930s.

Never before in peacetime has a country closed its factories and not shipped its finished products. This time manufacturing and foreign trade were frozen in China. Nor had it ever been seen that all services in all countries, some more than others, closed simultaneously, except for the United States, Great Britain and Mexico which closed later or did not close at all.

The contemporary societal lesson will be to have new forms of human contact, new forms of life. Global value chains must be rethought and industrialization policies must be rethought. Public health as a public good must return.
