A new report from NOAA and the American Meteorological Society paints a clear picture of the state of the planet: The climate crisis is not a future threat, but one that's already here.
The annual State of the Climate report found that 2021 was among the hottest years as the world saw record-high greenhouse gas concentrations, ocean heat and sea level rise, indicating that the effects of climate change are just getting worse.
The report, based on research from more than 530 scientists in more than 60 countries, is the "most comprehensive update" on Earth's climate and environmental update, according to NOAA.
And their findings were daunting. As climate scientist Zack Labe, who contributed to the report, said, "unsurprising, it was another alarming year for extremes."
A graphic from the report shows the wide range of areas affected by the climate crisis in 2021: Canada hit a new record high of more than 121 degrees Fahrenheit; Brazil's Rio Negro River hit record-high levels with floods that surpassed the damage of the "once-in-a-century" flood that hit in 2012; New Zealand had its warmest year in its 113-year record; eastern Africa had its worst food security in decades amid ongoing drought; and sea ice struggled to maintain its size.
Record-high greenhouse gas concentrations
Carbon dioxide, methane and nitrous oxide are the three most notable greenhouse gases that, once emitted, create a sort of cloak over the atmosphere that traps the sun's radiation, warming the planet. Last year, the concentrations of each of those gases hit a record high.
Carbon dioxide, which accounts for the greatest amount of global warming associated with human activities, notably the burning of fossil fuels, had a concentration of 414.7 parts per million – the highest in at least the last million years based on paleoclimatic records. Methane saw an increase of 18 parts per billion as its concentrations continue their steep increase since 2014. And nitrous oxide saw its third-highest annual increase since 2001, at 1.3 parts per billion.
