    🌡 2021 was tied for the sixth-warmest year since at least 1880, when ’s record begins. We work together with to track Earth’s global temperature as part of our work monitoring our changing climate.

    The bloom—known as a red tide or harmful algal bloom (HAB) event—was unusually widespread and long-lived. The red tide event spanned more than 200 kilometers of the coastline and lasted more than eight weeks.

    Beachgoers in the state of Rio de Janeiro contended in late 2021 with unwelcome ocean-dwelling visitors. Starting in November, countless microscopic phytoplankton amassed along the coast, coloring the clear, blue waters a dark, reddish-brown.

    “We are able to track this in real time & understand why it’s changing, & get people to notice...that gives me hope. Because we’re not in the dark here. We’re not the dinosaurs...We can see the comet coming, & we can act.”-Dr. Gavin Schmidt,

    Around the globe, we saw record-setting fires, floods and droughts. Both the Pacific and Atlantic saw intense tropical cyclones, with another near-record Atlantic season. Storms like Hurricane Ida and Cyclone Tauktae rapidly intensified before landfall.

    We felt the effects of a warmer climate in 2021, with a record hot summer in the continental United States, reaching temperatures last seen during the Dust Bowl in 1936. Heat waves pushed areas of the Northwest and Southwest U.S. to all-time highs.

    The climate change we see is the result of human activities — primarily burning fossil fuels — adding greenhouse gases like carbon dioxide to the atmosphere, where they trap more heat. Since about 1850, humans have raised atmospheric CO2 by nearly 50%.

    Heat and the energy it carries drive our climate. 's temperature record is one way we track heat. Another way to measure the energy trapped from greenhouse gases is ocean heat content, which reached record highs in 2021.

    With glaciers receding and plants claiming new territory in the Himalayas, scientists are looking into what the changes mean for the region's water supplies. The stakes are high. Twenty % of Earth's population relies on water from this region.
