Is the world warming faster than expected?
Is the world warming faster than expected? There have been historically
high sea temperatures, worrying lows in Antarctic sea-ice, and extreme
weather events hitting every continent – the latest being an “unbearable”
heatwave in Brazil. It’s now “virtually certain” that 2023 will be the
hottest year on record. That’s something that no major climate science body
expected at the start of the year.
Scientists have long known that
temperatures will continue to rise as humans keep releasing record amounts
of planet-heating greenhouse gases like carbon dioxide, mainly through
burning fossil fuels. This is the main cause of global warming. While they
are struggling to fully explain 2023’s “gobsmacking” surge in temperatures,
here are four additional reasons that could be behind the increases. A
‘weird’ El Niño; Cutting aerosols; A large volcanic eruption; An Antarctic
‘radiator’?
