The surface of the ocean is now so hot it’s broken every record since satellite measurements began

By Stephanie Pappas 14 April 2023 (Live Science) – Ocean surface temperatures have hit an all-time high this month, breaking every record since satellite measurements began in the 1980s. Temperatures reached a global average of 69.98 Fahrenheit (21.1 degrees Celsius) in the first days of April. The previous record of 69.9 F (21 degrees C) […]

Record-breaking algae bloom takes aim at Florida beaches – “This year could be the biggest year yet”

By Dinah Voyles Pulver 14 March 2023 (USA TODAY) – Beachgoers in Florida and the Caribbean could be greeted by heavy blankets of smelly seaweed in the weeks ahead as a 5,000-mile swath of sargassum drifts westward and piles onto white sandy beaches. Sargassum, a naturally occurring type of macroalgae, has grown at an alarming rate this winter. The […]

Estimated ocean parasite populations in the Puget Sound, 1880-2019. The count per host of ocean parasites that obligately require three or more hosts declined through time, while that of two- and one-host parasites remained stable. Shown are model predictions between the years 1880 and 2019 from phase 1 analysis. Predictions are for the “average” parasite species within each group (i.e., within 1-host parasites, 2-host parasites, and 3+-host parasites) where average is defined as “the parasite species with the abundance that is closest to the average abundance of all parasite species.” Graphic: Wood, et al., 2023 / PNAS

Warming oceans have decimated marine parasites, and that’s not a good thing – “If this can happen unnoticed in an ecosystem as well studied as this one, where else might it be happening?”

By Hannah Hickey 9 January 2023 (UW News) – More than a century of preserved fish specimens offer a rare glimpse into long-term trends in parasite populations. New research from the University of Washington shows that fish parasites plummeted from 1880 to 2019, a 140-year stretch when Puget Sound — their habitat and the second […]

Arctic annual air surface temperatures from October 2021 to September 2022 were the sixth warmest dating back to 1900. The image on the left depicts the departure from the average near-surface temperature across the Arctic during this period, with redder colors showing areas of greater than average warmth. The graphic on the right shows how the rate of Arctic air temperature warming has outpaced the rate of global warming. Data: ERA5 and NASA. Graphic: NOAA / Climate.gov

NOAA: Human-caused climate change fuels warmer, wetter, stormier Arctic

13 December 2022 (NOAA) – A typhoon, smoke from wildfires, and increasing rain are not what most imagine when thinking of the Arctic. Yet these are some of the climate-driven events included in NOAA’s 2022 Arctic Report Card, which provides a detailed picture of how warming is reshaping the once reliably frozen, snow-covered region which […]

Manatee relative, 700 new species now facing extinction

By Patrick Whittle 10 December 2022 (AP) – Populations of a vulnerable species of marine mammal, numerous species of abalone and a type of Caribbean coral are now threatened with extinction, an international conservation organization said Friday. The International Union for Conservation of Nature announced the update during the United Nations Convention on Biological Diversity, or COP15, […]

Hoof prints left by Camargue bulls mark a section of pasture encrusted with salt on the Raynaud ranch in Camargue, southern France, 23 September 2022. As soil salt levels rise due to drought and reduced river flow from the Rhone River, the land traditionally used by bull breeders like the Raynaud family is becoming more and more difficult to maintain as a suitable pace to raise animals.

In southern France, drought, rising seas threaten traditions – “The sea level rises on our coast and takes more and more of our land”

By Daniel Cole 30 October 2022 SAINTES-MARIE DE LA MER, France (AP) – In a makeshift arena in the French coastal village Aigues-Mortes, young men in dazzling collared shirts come face-to-face with a raging bull. Surrounded by the city’s medieval walls, the men dodge and duck the animal’s charges while spectators let out collective gasps. […]

Russia: Mass seal death likely due to oxygen deprivation

MOSCOW, 5 December 2022 (AP) – A top Russian environmental official said Monday that the thousands of dead seals that washed up on Russia’s Caspian Sea coast likely died from oxygen deprivation. Officials in the republic of Dagestan, which has a long coastline on the world’s largest inland body of water, said this week that […]

Tens of thousands of dead dolphins among environmental casualties of Ukraine war – “When the Black Sea was being bombed, we could feel it too”

By Stuart Greer 3 December 2022 (RFE/RL) – A Ukrainian marine biologist estimates that at least 50,000 Black Sea dolphins have been killed as a result of Russia’s ongoing invasion of Ukraine. Ivan Rusev says he’s shocked by the number of dolphin carcasses that have washed up on the shores of his nature reserve in […]

Aerial view of apparent red tide and other phytoplankton species in the water near Naples and Sanibel, Florida on 13 November 2022. According to the Florida Fish and Wildlife Conservation Commission, beaches from Sarasota to Port Charlotte varied between low, medium, and high levels of red tide. Because Hurricane Ian brought so much rain to Florida in October, scientists on the coast closely monitored water quality to see if the storm had any impacts.

Photos show toxic algae blooms plaguing southwest Florida waters – Runoff from Hurricane Ian suspected

By Dylan Abad 14 November 2022 TAMPA, Florida (WFLA) – Aerial photos revealed massive plumes of red tide stretching along much of southwest Florida’s coast days after Tropical Storm Nicole passed over the state. Photos released by Calusa Waterkeeper showed a deep reddish-brown discoloration of the water near Naples and Sanibel due to the presence […]

Components of the global carbon budget and their uncertainties, 1960-2021 and projected to 2022. Components are presented individually for (a) fossil CO2 and cement carbonation emissions (EFOS), (b) growth rate in atmospheric CO2 concentration (GATM), (c) emissions from land-use change (ELUC), (d) the land CO2 sink (SLAND), (e) the ocean CO2 sink (SOCEAN), and (f) the budget imbalance that is not accounted for by the other terms. Positive values of SLAND and SOCEAN represent a flux from the atmosphere to land or the ocean. All data are in GtC yr−1 with the uncertainty bounds representing ±1 standard deviation in shaded colour. Data sources are as in Fig. 3. The red dots indicate our projections for the year 2022, and the red error bars the uncertainty in the projections. Graphic: Friedlingstein, et al., 2022 / Earth System Science Data

Global Carbon Budget 2022: Global carbon emissions in 2022 remain at record levels – No sign of decrease in global CO2 emissions – “This year we see yet another rise in global fossil CO2 emissions, when we need a rapid decline”

11 November 2022 (Global Carbon Project) – Global carbon emissions in 2022 remain at record levels – with no sign of the decrease that is urgently needed to limit warming to 1.5°C, according to the Global Carbon Project science team (Global Carbon Budget 2022). If current emissions levels persist, there is now a 50% chance […]
