Our planet’s history includes episodes of cold so extreme that glaciers reached sea level in equatorial regions.
Por una gran mayoría, los científicos del clima están de acuerdo en que la temperatura global promedio hoy en día es más cálida que en la época preindustrial, y que la actividad humana es el principal factor contribuyente.
Unusually big blooms of tiny ocean plants occurred in the Arctic this past summer, linked to early summer retreat of sea ice.
Despite a few cold spots, it was the the second-warmest year on record Arctic wide. Since 2000, Arctic temperatures have been more than twice as far above average as the planet as a whole.
Between September 2019 and August 2020, the rate of ice loss from the Greenland Ice Sheet was much lower that the record set the previous 12-month period, but but still above the 2002–2020 average. Overall, Greenland continues to lose ice.
The 15th installment of NOAA's Arctic Report Card NOAA's 15th Arctic Report Card catalogs the numerous ways that climate change continues to disrupt the polar region.
Warmer conditions will pose new challenges for producers of Americans’ favorite side dish but advance knowledge and innovation will help potato growers prepare.
Arctic sea ice extent likely reached its annual minimum for 2020 on September 15. For the second time in the satellite record, sea ice extent dipped below 1.5 million square miles (4 million square kilometers).
In 2015, NOAA's Climate Program Office (CPO) invited grant proposals from sea ice and climate scientists looking to better understand and predict Arctic sea ice behavior, on timescales ranging from days to decades. This is our second story on some of the resulting research.
