The Earth’s temperature for 2021 will likely be between 0.91C and 1.15C above what they were in the years from 1850 to 1900 with a central estimate of 1.03C. Scientists expect next year to be slightly cooler than the last couple of years, but still one of the six warmest years on record. WHY? The reason is La Niña.
A phenomenon called La Niña in the tropical Pacific Ocean will result in a slight drop in temperature. La Niña occurs when strong winds carry surface Pacific Ocean water from South America towards the Philippines and are replaced at the surface by colder water from deeper in the ocean.
According to experts, it is expected to reduce sea-surface temperatures by 1–2C and will likely do enough to prevent 2021 from setting a new high mark.
The global temperature for 2021 is unlikely to be a record year due to the influence of the current La Niña, but it will be far warmer than other past La Niña years such as 2011 and 2000 due to global warming.
Researchers say the impact of a natural cooling event like La Niña, while important, is hugely overshadowed by the warming driven by greenhouse gases in the atmosphere.
There was a strong La Niña in the year 1999–2000, but global temperatures have gone up by 0.4C in the years since then.
2016 remains the warmest year on record with 2020 vying for second place with 2019. The year 2021 is expected to edge out 2018 for sixth place.
Will the year be really cooler? Let’s see, but in any case, if we really want to reduce greenhouse gas emissions, the automotive industry’s transition to electric mobility must be accelerated.
Many sceptics will say, but electric cars need electricity, which will still be sourced from coal/nuclear power plants.
And they will be right, but only partly. Why? Because in many countries, strategies have already been defined to shut down coal/nuclear power plants, impose CO2 taxes, etc.
And the auto industry is trying to do almost everything on its own.
