Because of the way the climate and ocean systems respond to heat-trapping emissions, sea levels will continue to rise even after air temperatures stabilize. So, even in a future scenario where the world achieves the stabilization of air temperatures, the Earths oceans and cryosphere (frozen regions like Antarctica ) will continue to adjust.
The year 2023 was by far the warmest in Earths recorded history, and perhaps in the past 100,000 years , shattering the previous record set in 2016 by 0.27C (0.49F). Over the last few decades, there has been an observed decrease in total planetary cloud cover , especially over the North Atlantic Ocean off the Northeast US coast.
First, it’s been obvious for months that 2023 would be a record year – in temperatures (at the surface, troposphere and in the ocean), in Antarctic sea ice, in the number of big climate disasters etc. Ongoing issues Last year at this time, I discussed ongoing work to understand trends in the Southern Ocean. Why oh why?
As you can see though, the size of the residual for 2023 was comparable to 2016 and 1998 (years that started with large El Nio events), and 2024 had the highest residual in decades despite the recent El Nio only being a moderate event. Allan, and C.J. 044002, 2025. Terhaar, F.A. Frlicher, and T.F.
It is easier to deal with the balance at the top of the atmosphere or use a simplified description that includes convection and radiation as discussed here previously on RealClimate and presented in Benestad (2016). 679-688, 2016. Focusing on the tropics easily gives too high values for water vapour if applied to the whole planet.
Maine which provides a nice front end to the NOAA NCEP CFS forecast system and reanalysis and shows absolute daily temperatures in early July clearly exceeding the highest pre-existing temperatures from August 2016. It’s an arresting graphic, and follows in from the record high ocean surface temperatures that were being reported a month ago.
These delightful beings can be found from the warm, shallow waters of the Indian Ocean (including the Red Sea) to the Pacific Ocean. diadema (2016), I. The post Meet the Idiomysis Shrimp, the Social Butterfly of the Ocean appeared first on Ocean Conservancy. That means they are less than one centimeter in length !
FIRO started in California and has since gone worldwide Once upon a time, there was (and still is) a megadrought in California that peaked in the acute drought of 2012 to 2016. In other words, FIRO avoids the fear of missing out (FOMO) on water that you could have stored if you had better forecasting.
Not in summer when the ocean is covered by a shallow surface mixed layer heated by the sun and highly dependent on weather conditions.) The argument has been made that the ‘cold blob’ might not be caused by an AMOC decline but by heat loss at the ocean surface. We argued in Caesar et al. The reanalysis data show the latter is the case.
I think in hindsight that my concerns from 2013 to some extent were supported by the fact that the IPCC organised an Expert Meeting on Communication, Oslo, Norway, 9–10 February 2016. Carbon dioxide (CO 2 ) is the most important greenhouse gas that we have added to the atmosphere, however, some of it has been absorbed by land and oceans.
Projections of (a) temperature (constrained), (b) Arctic sea ice area (raw CMIP6), (c) ocean pH (constrained), and sea level (d)to 2100, and (e) to 2300 (constrained). Since 2012, global surface temperature has warmed strongly, with the past five years (2016–2020) being the hottest five-year period between 1850 and 2020 ( high confidence ).
2016 ), a reduction of Saharan dust concentration since the 1970s ( Evan et al. 2016 ), could increase again in concentration. 2016 ), in addition to a long-term decline ( Caesar et al. 242-246, 2016. Bennartz, "The Role of Aerosols in the Evolution of Tropical North Atlantic Ocean Temperature Anomalies", Science , vol.
The radiative forcing from these changes in concentrations can be easily calculated using standard formulas (from Etminan et al, 2016 which supersede the slightly simpler ones from IPCC TAR), as about 2 W/m 2 for the CO 2 change and 0.65 W/m 2 for CH 4. In contrast, methane has a perturbation time-scale of about 12 years. Highwood, and K.P.
A particularly devastating bloom on the Chilean coast in 2016 killed an estimated 27 million farmed salmon and trout. He wants to incorporate layers of data on climate change, nutrient inputs from aquaculture and agriculture, and ocean dynamics. Anecdotal evidence suggests that these marine harmful algal blooms are on the rise.
The IPCC AR6 report used the most up-to-date estimates from Etminan et al (2016) which are similar but slightly more complicated than the simplified, oft-used formula for CO 2 : RF = 5.35 ln(CO 2 /CO 2 _orig) (seen in Table 6.2 in IPCC TAR). Step 6: Radiative forcing x climate sensitivity is a significant number. Highwood, and K.P.
The physics-based models describe how energy flows through the atmosphere and ocean, as well as how the forces from different air masses push against each other. See for instance Benestad (2016). Furthermore, the volume of the oceans increases from the melting of land ice. 679-688, 2016. References R.E.
In 2016, the Human Rights Council declared that damage to cultural heritage, both tangible and intangible, of any people, constitutes damage to the cultural heritage of humanity as a whole.
Though essential to ocean life, they produce plenty of drawbacks, too. A particularly devastating bloom on the Chilean coast in 2016 killed an estimated 27 million farmed salmon and trout. He wants to incorporate layers of data on climate change, nutrient inputs from aquaculture and agriculture, and ocean dynamics.
Lead author Adam Gold , a watershed researcher for the Environmental Defense Fund, said the wild uncertainty is because the court arbitrarily created a new standard for federal protection divorced from the science of how wetlands support larger streams, rivers, lakes and the ocean.
It works for progress on methane pollution, clean electricity, clean transportation, forests, fisheries and oceans, healthy communities, fuels and feedstocks, agriculture, water, food, carbon markets and other critical environmental challenges.
This blog was co-written by Susanna Goodell, Ocean Conservancy’s Communications intern for the Spring 2021 term and a member of the Dartmouth College Class of 2023, majoring in Environmental Studies. As we head into September, Ocean Conservancy is gearing up for this year’s International Coastal Cleanup (ICC) season.
But now, a side deal in Congress is threatening to sideline the public’s voice in decisions that will directly affect our ocean, our coasts and our communities. Prior to my time as CEO of Ocean Conservancy, I was a litigator defending ocean ecosystems and marine mammals, and NEPA was a critical tool in that defense.
On the back of the dark and sombre Intergovernmental Panel on Climate Change (IPCC) cli mate report released last week, the US government agency National Oceanic and Atmospheric Administration (NOAA) has confirmed that this July was the warmest month ever experienced on Earth. of a degree C higher than the 2016 record.
By Deborah Pirchner, Frontiers science writer Image: Rob Lachlan As ocean temperatures rise, corals can lose their color due to heat stress. One of the worst mass bleaching events occurred in 2016 and 2017 on the Great Barrier Reef, causing bleaching on 91% of the system’s reefs.
In 2016, I first traveled to the island nation of Vanuatu with a mission: to understand the real-life impacts of ghost gear (abandoned, lost or otherwise discarded fishing gear) on the local communities.

My entire childhood was spent with close proximity to the water and greatly inspired my love for our ocean and desire to begin working at an organization focused on protecting it. Here at Ocean Conservancy, we have been celebrating Pride all month long. Thanks for signing up for Ocean Conservancy emails. Love our content?
The island nation has always been at the mercy of climate patterns such as La Niña in the oceans that surround it. National Oceanic and Atmospheric Administration, highlighted new threats facing the Arctic: marine trash and noise pollution. Traffic from fishing, cargo, and military ships has increased by 58% between 2016 and 2019.
Wildfire in Canada , smoke in NYC , heat domes in Texas , massive heat in the Atlantic ocean are just some of this month’s news. At the top of that list is JPMorgan Chase, the largest funder of fossil fuels cumulatively since the Paris Agreement on climate change was signed in 2016, according to the report.
The 24-month study process begins with the Colorado Basin River Forecast Center, a team of scientists operating within the National Oceanic and Atmospheric Administration. Cody Moser, a senior hydrologist at the Center, told Circle of Blue that data from the years 2016 through 2020 will be added this fall. Click To Tweet.
Results from the first multi-institutional ghost gear removal program in the vaquita marina area launched in 2016, showed that more than 1,300 nets were removed from the Northern Gulf of California (Sea of Cortez) as of 2020.

The global scale of plastic production means that these tiny fragments of plastic are now ubiquitous, and scientists fear that ocean currents will cause plastic to accumulate in the Arctic, damaging ecosystems. It is even found in the polar oceans and the deepest ocean trenches.” and 10cm in size) for a different study.
In the past few years, physicists have begun to realize that it could have a major role in fluid dynamics – the Earth’s oceans, for example, or plasmas, or the biological cells in fluid-like “active” matter. Both von Klitzing and Thouless won the Nobel Prize for Physics for their contributions, in 1985 and 2016 , respectively.
In a new paper published in Frontiers in Earth Science , researchers investigated how tropical cyclones’ destructive power has changed over the eastern and southeastern regions of Asia between 1979 (hereafter) and 2016. Other research has also shown that heating oceans could intensify their strength.
During the year as a whole the record was not just broken, but broken by a great amount as 2023 was 0.17C hotter than 2016 – the previous hottest year. This warms the surface waters in the eastern Pacific Ocean and contributes to higher global temperatures.
Since 2016 the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) has been giving small funds to farmers who plant cover crops or switch to no-till farming. These practices can limit runoff, but they are expensive to implement.
I’ve had many black women as role models, but I didn’t see any in marine science until I started at Hampton University in 2016, which is a historically black university, where our department chair was a black woman. I asked whether she had any role models, in particular Black women, in marine science growing up.
Wild-caught seafood from our ocean is no exception. Climate change is making the ocean warmer, more acidic and lower in oxygen. Northern shrimp, found in the northeast, are highly vulnerable to climate change, according to a climate vulnerability assessment done by the National Oceanic and Atmospheric Administration (NOAA).
The researchers add that the clock might also aid Solar System exploration – making it possible, for example, to plot the gravitational field of Jupiter’s moon Europa to see if there might be an ocean under its icy crust. However, not everyone is convinced. 15 per day underwhelming. The research is reported in Nature.
Ocean ecosystems, Indigenous cultures, commercial and recreational fishing, and coastal livelihoods and economies—all of these rely on abundant fish populations. Since 2016, we’ve rebuilt 8 stocks, but in the five years before that, 18 stocks were rebuilt. . Thanks for signing up for Ocean Conservancy emails.
According to the respected International Energy Agency’s new report, global greenhouse gases emissions from energy remained flat in 2016 while the global economy grew by 3.1 Coal demand fell worldwide but the drop was particularly sharp in the United States, where demand was down 11% in 2016. Deforestation is one.
Therefore, it is hardly surprising that National Oceanic and Atmospheric Administration (NOAA) earlier this month confirmed that July was the warmest month ever measured since records began. It beat a five-year-long record that had stood been measured since 2016.
The sprawling Semitropic Water Storage District in Kern County wants Kings River flood water that it says current rights holders are letting flow to the ocean in heavy precipitation years. million in 2015 and 2016 and another 35,000 acre feet of river water for an undisclosed amount in 2019.
