An AMOC weakening by 15 % thus cools the region at a rate of 0.15 x 10 14 W and according to model simulations can fully explain the observed cooling trend (2). Here we start by taking the Greenland mass loss rate into the ocean, times the temperature difference between the meltwater and the water it replaces.
Of the 24 CMIP6 models, a full 23 underestimate the sea surface cooling in the ‘cold blob’ And most of the CMIP6 models even show a strengthening of the AMOC in the historic period, which past studies have shown to be linked to strong aerosol forcing in many of these models (e.g. So what is this whiplash about?
Its a great question, but the warming effect from heat-trapping gases far outweighs the cooling effect from industrial aerosols. 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.
More than 8,000 years ago, as the planet thawed following the end of the last ice age, Northern Europe abruptly cooled. New research reveals that Arctic ice melt weakened a critical ocean current, leaving Europe in the cold, a finding with important implications for future climate change. Read more on E360 →
Unlike in years past, there is no longer any serious discrepancy between the records – which use multiple approaches for the ocean temperatures, the homogenization of the weather stations records, and interpolation. Southern Ocean trends. The least visited part of the ocean are the waters around Antarctica.
The Atlantic meridional overturning circulation (AMOC) is a large-scale overturning motion of the entire Atlantic, from the Southern Ocean to the high north. Graph by Ruijian Gou. The AMOC is a big deal for climate. It moves around 15 million cubic meters of water per second (i.e. 15 Sverdrup). Take the IPCC reports.
However, for our ocean and the planet, the real fright comes from plastic waste. Plastic candy wrappers, plastic decorations and other plastic waste have serious impacts on our ocean and marine life. Love ocean content? Our ocean is counting on us to take a stand, and together—we can make a difference. We are too.
The paper results from a major computational effort, based on running a state-of-the-art climate model (the CESM model with horizontal resolution 1° for the ocean/sea ice and 2° for the atmosphere/land component) for 4,400 model years. Figure adapted from Caesar et al., Nature 2018.

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?
Thanks for signing up for Ocean Conservancy emails. Ocean Conservancy: Can you give us an overview of your current research? It’s a cool field to study because there are so many facets and rabbit holes that you can go down to get a holistic picture of how evolutionary forces produce skull shape. Every fish is cool.
The primary cause of accelerating sea level rise is human activity As people burn fossil fuels and emit heat-trapping gases like carbon dioxide, our atmosphere and our oceans warm up. As the ocean warms, it expands. That adds water to the oceans, which raises their level. Cool, right?)
If the AMOC weakens, this region will cool. And in fact it is cooling – it’s the only region on Earth which has cooled since preindustrial times. Not in summer when the ocean is covered by a shallow surface mixed layer heated by the sun and highly dependent on weather conditions.) From Rahmstorf and Ganopolski 1999.

Up to this point, the ocean has been our greatest guardian against extreme heat and catastrophic climate changes.
Two decades ago, in an interview with science journalist Richard Kerr for the journal Science, I coined the term the “Atlantic Multidecadal Oscillation” (AMO) to describe an internal oscillation in the climate system resulting from interactions between North Atlantic ocean currents and wind patterns. Background.
In an unchanging climate, the random fluctuations would lead to warming in some parts of the world and cooling in others. In a world with just random local fluctuations but no climate change, about half the weather stations would show a (more or less significant) warming, the other half a cooling. It’s not hard to understand.
There is no doubt that we have changed Earth’s climate through our activities on a broad range of aspects that includes consequences for the atmosphere, the oceans, snow, ice, Earth’s fauna and ecosystems. In addition, ozone depletion higher up in the stratosphere has caused a cooling high up in the atmosphere. mm increase every year.
What they showed are the distinct fingerprints of two kinds of forcing; increasing solar activity which warms all parts of the atmosphere, and carbon dioxide increases which warm the surface and troposphere, but cool the stratosphere and above. The basic issue stems from the different timescales of the ocean and atmosphere.
Think about what is involved – biological proxies from extinct species, plate tectonic movement, disappearance in subduction zones of vast amounts of ocean sediment, interpolating sparse data in space and time, degradation of samples over such vast amounts of time. All of which adds to the uncertainty.
The mix of warming and cooling effects and different timescales for each, makes calculating the impact hard. a net cooling!). W/m 2 over the ocean (which translates to 0.14 2024) Looked at the impact of Chinese aerosol emission decreases from 2010 to 2020 and saw increases in North Pacific ocean temperatures.
Jump on in and take a trip down to Bikini Bottom with us and meet some of the real ocean animals behind this world-renowned cartoon cast! But, for the sake of this blog (and the fact that the series’ creator was a marine science teacher and thought sea sponges were super cool and underrepresented animals), let’s say he’s a sea sponge.
These are needed at global, regional and ‘thematic’ levels – given the diverse scales of tipping elements in oceans, forests and the cryosphere, for example. This means redoubling efforts to cut emissions, and reliably constrain temperature rises, not gambling on speculative technological interventions to cool the planet.
After months of delay, the cool La Nia climate pattern has emerged in the eastern tropical Pacific Ocean, which increases the risk of drought in parts of the Americas
From religion major to glass blower to leader in global ocean conservation, Lizzie McLeod’s career path has been anything but conventional. The post Meet Lizzie McLeod, TNC’s Global Oceans Director appeared first on Cool Green Science.
I recently represented Ocean Conservancy at the National Working Waterfronts Network Conference in San Diego. As an engineer, former mariner and ocean conservationist I know that decarbonizing our ports requires cross-sector partnerships. Now is the time to turn conversations into action.

The La Niña weather pattern, driven by normal cooling cycles in the eastern Pacific, has always caused dry spells in East Africa. But as global greenhouse gas emissions rapidly warm the western Pacific Ocean, the La Niña is becoming more frequent and severe. Scientists say the pattern is yet another effect of global climate change.
They could cool the Earth on average but not precisely undo the patterns of disruption from GHGs. (I touch on this in a new paper at the Annual Review of Environment and Resources with my co-author David Keith. More on this paper in coming blog posts.) These interventions would not precisely offset greenhouse-gas-driven climate change.
These eight-legged oddballs of the ocean have always had a dedicated fanclub, and the recent documentary My Octopus Teacher helped millions more people fall in love with them.

As ocean waters warm , more water evaporates into the air, which then results in more intense and frequent rain or snow.
Meanwhile, note that the factors listed above involve the whole Earth system: the oceans, the cryosphere, the atmosphere, the solid earth and lithosphere, and a full range of scales, from the city block and shoreline, to ice dynamics that change over kilometers, to GRD footprints, to the whole global ocean. 2020) or Sadai et al.
The surface of Venus may have remained extremely hot since its formation, meaning that water in the atmosphere never had a chance to fall to the surface

It wasn’t long after dawn—still the cool of the day—but I could feel the weight of summer bearing down. I was probably the largest creature walking around these quiet woods, and it would soon be too hot for me to think about anything except reaching the ocean on a vacation still a few weeks in the future.

New research finds coral refugia, where reefs are protected from global warming by cool local currents, are disappearing faster than expected. By Bob Berwyn In the race to save at least some remnants of the world’s coral reefs, a new study shows only one thing really matters—capping global warming at 1.5 degrees Celsius.
‘Despite decades of warnings, we are still heading in the wrong direction’ By Bob Berwyn Research released this week raises new questions about how much more Earth may warm, or cool, if and when human carbon dioxide emissions zero out.
Clouds of dust blown from the Sahara desert generally have a cooling effect on the North Atlantic, but the winds that blow the dust are weaker than usual, possibly due to El Niño
