The year 2023 was notable for setting several historic records. Greenhouse gas levels, global temperatures, sea level rise, and Antarctic sea ice melt have all reached unprecedented levels. It was the warmest year since global records began in 1850, with a temperature 1.18°C above the 20th-century average. Drastic changes in weather patterns, enhanced by global warming, have caused significant impacts on the environment, society, and the economy worldwide.
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.
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.
