2020 was one of the two warmest years on record, tied only with 2016.
According to the European Union’s Copernicus Climate Change Service, in 2020, average temperatures globally were 2.7 degrees Fahrenheit (1.25 degrees Celsius) warmer than preindustrial levels — the point at which scientists agree that human activity, and particularly the burning of fossil fuels, began to accelerate global warming.
In nearly every way, 2020 was a record year for climate-related disasters.
The impacts of the record heat have been felt both around the globe and in the United States. Historic wildfires burned in California, Colorado, Australia, and the Amazonian rainforest. The Atlantic hurricane season produced a record 30 named storms.
Swarms of crop-destroying locusts invaded East Africa, causing devastation to a region already struggling with food insecurity. The Arctic, the area that is currently warming faster than any other place on the planet, saw record declines in ice cover as well as records for how late in the year the ice actually froze.
Even more troubling, 2020’s high temperatures occurred despite the absence of an El Niño event, which typically has the effect of warming the globe; 2016, the other warmest year on record, had an El Niño.
So 2020 being the warmest on record, without an El Niño event, indicates just how much human activity is changing the world around us.
Lockdowns due to the coronavirus pandemic and global traffic coming to a halt contributed to a 7 percent drop in emissions. However, the concentration of atmospheric carbon dioxide actually grew to record highs in May.
Recently released figures from NOAA found that more than 20 climate- or weather-related events costing $1 billion or more hit the United States last year — from a combined drought and heat wave in Colorado to hailstorms and heat waves that struck parts of Ohio.
According to figures from a report by Munich Re, environmental disasters cost the world $210 billion in 2020. The US alone accounted for $95 billion of that sum, nearly double the cost of damage in 2019.
Limiting warming to well below 2 degrees Celsius above preindustrial levels, the fundamental goal of the Paris climate agreement, will require countries worldwide to commit to making a rapid transition away from fossil fuel-intensive practices to renewable energy.
It’s time for the world to get more ambitious with its emissions targets
The Paris climate pact, which just had its fifth anniversary, contains a mechanism for countries to make even stronger commitments.
Yet while many countries in 2020 made headlines for announcing quicker timelines for moving to net-zero emissions, a recent analysis showed that just 45 parties (44 countries, plus the EU’s 27 member states, viewed as one…
