According to fresh data released on Wednesday, April was the warmest on record worldwide, with record heat, rain, and flooding severely impairing regular living in several countries.
Sample this, the European Union’s climate agency Copernicus Climate Change Service asserts that it was also the 11th consecutive month of record-high temperatures and attributes combined influence of climate change caused by humans as well as the El Nino, which is weakening now.
With an average temperature of 15.03 degrees Celsius, April’s temperature was 1.58 degrees Celcius higher than that of the pre-industrial reference period, which runs from 1850 to 1900.
It was 0.14 degrees Celsius higher than the previous record set in April 2016 and 0.67 degrees Celsius higher than the average for April from 1991 to 2020.
“El Nino peaked at the beginning of the year, and the sea surface temperatures in the eastern tropical Pacific are now going back towards neutral conditions. However, while temperature variations associated with natural cycles like El Nino come and go, the extra energy trapped in the ocean and the atmosphere by increasing concentrations of greenhouse gases will keep pushing the global temperature towards new records,” Carlo Buontempo, Director of C3S, warns.

According to the climate agency, the average global temperature over the last 12 months is the highest on record, rising 1.61 degrees Celsius above the pre-industrial average of 1850-1900 and 0.73 degrees Celsius above the average of 1991-2020.
What Does C3S Indicate? (Environment News Updates in India)
C3S reports that in January, the average worldwide temperature crossed the 1.5 degree Celsius mark for the first time in a whole year.
However, long-term warming over several years is referred to as a permanent breach of the 1.5 degrees Celsius limit stated in the Paris Agreement.
Climate scientists advise nations to prevent the worst effects of climate change by keeping the rise in world average temperature to 1.5 degrees Celsius above pre-industrial levels.
Because greenhouse gases, mainly carbon dioxide and methane, are becoming more concentrated in the atmosphere, the average global surface temperature of Earth has already risen by around 1.15 degrees Celsius from 1850–1900.
Global records for drought, wildfires, and floods are attributed to this warming.
A recent study by researchers at Germany’s Potsdam Institute for Climate Impact Research estimates that by 2049, the effects of climate events could cost the world economy approximately USD 38 trillion annually, with the least responsible countries suffering the most and having the fewest resources to adapt to the effects.
At 1.45 degrees Celsius above the pre-industrial baseline, the average global temperature in 2023 was the highest in the 174-year observational period.
Since El Nino cyclical warming of the ocean surface in the central and eastern tropical Pacific Ocean usually has the biggest impact on global climate in the second year of its development, the warming may break all previous records in 2024, the scientists maintain.
According to C3S scientists, although El Nino kept waning and moving toward neutral conditions, maritime air temperatures in April generally continued to be abnormally high.
The world is currently experiencing extreme weather due to both human-caused climate change and the El Nino that is expected in 2023–2024.
Except for Indonesia, Malaysia, and Myanmar, a severe heatwave across Asia forced the temporary closure of schools in the Philippines and set new records for temperature in India, which is currently holding a 44-day general election.
The UAE experienced its heaviest rain in 75 years during the month.
Additionally, April marked the twelfth straight month with record-high ocean temperatures, according to C3S scientists.
The India Meteorological Department is one of the international weather institutions that predicts La Nina conditions by August or September.
La Nina conditions, which are the opposite of El Nino conditions, result in an abundance of rainfall during the monsoon season, while El Nino conditions are linked to weaker monsoon winds and drier conditions in India.
The IMD predicted in a mid-April bulletin that La Nina conditions will be the primary cause of India’s above-average cumulative rainfall during the 2024 monsoon season.
El Nino normally lasts nine to twelve months and happens every two to seven years on average.
November and January are when the current El Nino phenomenon, which began in June 2023, is at its peak. Environment news updates in India to brace up for the brutal heat.
It is linked to exceptionally dry and warm weather in Southeast Asia, Australia, and southern Africa, as well as enhanced rainfall in the Horn of Africa and the Southern US.
What exactly is “El Niño” and what consequences does it have?
El Niño, which means “the Christ Child” in Spanish, describes above-average sea surface temperatures in the central and eastern tropical Pacific Ocean, which cause the ocean to warm.
Normally travelling from east to west near the equator, the low-level surface winds are known as “easterly winds”.
However, in certain instances, these winds may start blowing in the other way, from west to east, and become weaker.
El Niño occurs sporadically, ranging from two years to ten years, and no two occurrences are quite the same.
El Niño occurrences have the potential to upset regular weather patterns both domestically and internationally.
