In an effort to discover what caused the Great Permian extinction about 252 million years ago, scientists at the University of Washington have conducted a new study. .

Up to 96% of all marine species and 70% of land animals were killed off during the Great Permian extinction, an event that is considered the worst mass extinction in the history of our planet.  It is thought that during the Permian extinction, volcanoes in Siberia released so much carbon dioxide into the atmosphere that Earth's temperature went up by about 10 degrees Celsius. .

This new study suggests the Great Permian extinction was caused primarily by rapidly increasing temperatures.  The researchers made their conclusion after examining marine fossil records and using a climate model with Earth’s configuration during the Permian  to recreate the effects of rising temperatures 252 million years ago. .

New SOCCOM research published this week in Nature is the first to show how the melting of the Antarctic ice sheet will affect future climate. The study finds that as Antarctic ice sheets melt, atmospheric warming will slow, while speeding up sea level rise.⠀
⠀
Observations show that the Antarctic ice sheet has been melting faster in recent years. The SOCCOM team found that by the year 2100, sea level could rise as much as 10 inches more than the previous estimate of approximately 30 inches by 2100. In addition to slowing warming and increasing sea level, the melting of the Antarctic ice sheet will change precipitation regimes because the tropical rain belt will shift north. ⠀
⠀
Another SOCCOM team has deployed robotic floats throughout the Southern Ocean that are gathering temperature, salinity, and biological and chemical information about the ocean. Senior author Joellen Russell of University of Arizona said her next steps are evaluating climate models against the observations from the SOCCOM floats to see what else the models might be missing.⠀

While it is really fun to be in the #lab where I can use different #chemical techniques to infer past climate changes, data collected from the lab requires interpretation so that I can put my results into a climate context. The second part (with Baylor Fox-Kemper) of my "lab" work focuses on using observation and climate models to help interpret data collected from the field and lab so that we can understand how and why the climate has changed in the past!

As the SOCCOM profiling floats bob around in the Southern Ocean, researchers also take direct measurements of oceanographic conditions. On this expedition, the CTD rosette was deployed from the Baltic Room on the R/V Palmer. ⠀
⠀
A CTD measures conductivity (which helps determine salinity), temperature, and depth. This instrument runs profiles of the water column and along the way, collects discrete water samples (at specific predetermined depths) using the rosette of niskin bottles. Each bottle can collect a water sample. With float data and ship data, researchers are attempting the fill in the gaps of data in the vast Southern Ocean. ⠀

The SOCCOM program operates profiling floats in the Southern Ocean as part of a global fleet of floats known as the Argo array. The profiling floats drift freely, taking measurements from two kilometers depth to the surface every 10 days over a lifetime of five to seven years. Profiling floats have allowed scientists to collect oceanographic measurements year-round. Here, a float is deployed from the R/V Palmer during the 2016-2017 cruise to the Southern Ocean. ⠀

SOCCOM research has found that freshwater plays the most powerful role in changing water density in the Southern Ocean. The change in density drives circulation and the melting of wind-blown sea ice contributes 10 times more freshwater than melting of land-based glaciers. ⠀

Overturning circulation brings deep water and nutrients up to the surface, carries surface water down, and distributes heat and helps store carbon dioxide as it flows through the world’s oceans, making it an important force in the global climate system. Photo by Hannah Zanowski.

Who says the Southern Ocean is inaccessible? Anyone who's ever taken the long journey there on an icebreaker! Learn more about the Southern Ocean and the how scientists are unlocking its mysteries on the @SOCCOMproject. . . . 
Despite its importance to the Earth’s climate, its rough winds and inaccessibility have kept the biogeochemical dynamics of the Southern Ocean essentially an enigma to scientists. SOCCOM, aims to collect as much information as possible about the Southern Ocean and its connection to the climate. Using 200 autonomous floats, SOCCOM has been taking measuements on the Southern Ocean’s oxygen, nitrate, and carbon content in order to investigate its role in the global carbon cycle. It’s clear that the Southern Ocean absorbs enormous amounts of anthropogenic carbon dioxide, but as it continues to be flushed with carbon dioxide, the absorption power of the Southern Ocean will begin to wane, and Southern Ocean sponge may only be able to hold back the effects of climate change for so long. The data records from SOCCOM can help predict how it will change over time depending on how the world’s carbon output changes.

Understanding the processes that change the water retention properties of large river basins and their influence on runoff is essential for those working on earth system models. A new paper from an international team of climate modellers looks at the issue. Pictured is the #Yukon river, #Canada, one of 33 large-scale catchments analysed in the study out now in Environmental Research Letters.

Two leopard seals rest on a large chunk of sea ice. ⠀

Antarctic sea ice is constantly on the move as powerful winds blow it away from the coast and out toward the open ocean. SOCCOM scientists used a computer model to synthesize millions of ocean and ice observations collected over six years near Antarctica and estimated the influence of sea ice, glacier ice, precipitation and heating on ocean overturning circulation. Overturning circulation brings deep water and nutrients up to the surface, carries surface water down, and distributes heat and helps store carbon dioxide as it flows through the world’s oceans, making it an important force in the global climate system. The scientists found that freshwater played the most powerful role in changing water density, which drives circulation, and that melting of wind-blown sea ice contributed 10 times more freshwater than melting of land-based glaciers did.

What is ‘hothouse earth’ or ‘runaway climate change’? ‘Hothouse earth’ is a possible consequence of climate change identified by scientists, whereby the climate could stabilise at global temperatures 4-5 degrees C higher than pre-industrial temperatures (i.e leaving many places uninhabitable). This COULD start happening when temperatures reach 2 degrees C higher (we’re already at 1) due to altering ‘feedback loops’ which normally help cool the earth - to instead cause warming. An example is if large amounts of arctic ice melts this will vastly reduce the amount of sunlight reflected back to space, another is if the permafrost in the Northern hemisphere thaws this will release large amounts of greenhouse gases. Obviously these things are based on studies and models and difficult to prove completely, but why oh why would we not try and prevent it anyway??

🔮Climate models are generated by very powerful supercomputers that predict averages or statistical ranges of climate conditions in future seasons and decades. They include the effects of a changing ocean and atmospheric chemistry, which don’t have an impact on the atmosphere over the span of a few days. Short term weather forecasts are highly accurate and have improved in the last decade. Weather forecasts are based on statistical relationships between current conditions and atmospheric conditions for the next few months.

#FreshHotScience ~ Though it looks like a fire itself, this is actually a map of the carbon emitted from forest fires in the Northwest Territories (NWT) of Canada during the mega fire year of 2014, in which 94 million tons of carbon went up in smoke. That’s equivalent to taking all the oil spilled during the Deepwater Horizon disaster, multiplying what you’ve got by 200x, and then burning every last drop. These mega fires were so big they burned off half the carbon that all of Canada’s forests and soils absorb in one year. In other words, you cannot think about using land to mitigate climate change without accounting for wildfires, and right now fires are not integrated into any climate mitigation plans. Here, red indicates higher emissions per square meter (the grey splotches are lakes). This work was published recently by a team at @nauflagstaff and WHRC scientist Dr. Brendan Rogers. 🖇 in bio. // Map & analysis by Rogers // #ScienceForTheWorld

Best day of the week is Friday! Not because it is time for a well-deserved weekend, but because we at #CentreforIceandClimate #Nielsbohrinstitute have a joined lunch with an invited speaker treating us with some of the most novel results within #icecore research and #paleoclimate afterwards. And this almost every Friday!
.
Today Ayako Abe-Ouchi from the university of Tokyo gave an exciting talk on modelling the last #deglaciation with Global Climate model #GCM developed in Japan. During the last glacial period, the North Atlantic region experienced a series of Dansgaard–Oeschger cycles in which climate abruptly alternated between warm and cold periods (15 degree changes in Greenland within decades!!). The reason for these abrupt climate changes is still debated.
.
Ayako Abe-Ouchi and co-workers investigated the Atlantic meridional overturning circulation #AMOC and found large self-sustained oscillations resulting in high latitude temperature change similar to Dansgaard-Oeschger cycles only under a limited range of CO2 and #freshwater forcing, helping constraining the potential mechanisms.

Everything is frozen in time in the northeast. Trees stopped budding. Grass isn't growing. Birds aren't chirping. It quiet, its lonely, it's like January. It should be cold for a few days in April, not for weeks with a snow storm. Mother nature is not happy, climate change is breaking us, and our home down

Hit the slopes with PNAS! Pictured is a mountain snowpack in Park City, Utah. Sarah B. Kapnick et al. used global climate models and climate data to predict seasonal snowpack in the western U.S. The models predicted seasonal snowpack for March using climate conditions from July 1 of the previous year, and outperformed statistical predictions of March snowpack. According to the authors, models for predicting seasonal snowpack might aid water resource management. See the article by Sarah B. Kapnick et al. at www.pnas.org.

The fires of climate change can quickly turn rainforest into savannah. When you lose forests, you lose the carbon they store, the water they cycle, and the species that live there. We are using our large-scale fire experiment in Mato Grosso, Brazil, to predict how climate change will impact the entire Amazon Basin and the global climate. // Photo by @pbrando // #LIT #experiment #climatechange #brazil #elnino #drought #climatescience #matogrosso #amazon #brazil #remotesensing #forestfire #climateadaptation #climate #carbon #forest #rainforest #tanguro #soybean #feedtheworld #restoretheworld #conservetheworld #earth #climatemodel #satelliteimagery #ecosystem #carbon #fieldwork #brazil #matogrosso

Climate models are at the heart of climate change science. Over time they have increased in complexity, since the first basic models were created during the 50s and 60s. Today, the vast computing power required for simulating the weather and climate means that the models are run on massive supercomputers.

PNAS is here! Pictured is a supraglacial river on the Greenland ice sheet. Laurence C. Smith et al. measured meltwater discharge in a supraglacial river for 72 hours in July 2015 while mapping its upstream catchment using high-resolution satellite and drone images. The data were used to calibrate a hydrological model that yielded more accurate estimates of the volume and timing of runoff compared with climate models, suggesting that supraglacial river catchment size and shape influence the timing and volume of meltwater entering moulins and the ice sheet bed.

This DIVA model shows solar thermal gain on the floor surfaces of an existing home, built in the 1780s - it's part of one of our research projects here at Runcible. We're pretty curious around here, and we love using digital tools to help us understand how buildings work. Here, we're using this model to explore and uncover vernacular builders' techniques for climate mediation. We have a lot to learn from those who came before us, and digital tools can help us do that!

Climate Modeling? 😂 The best part of having the lab to myself is that I can take punny photos for #scienceathon without being judged! I'm very sorry for this 😂 Don't worry, I'm still doing actual work (see photo 2) #dayofscience #climate #model #climatemodel #womeninscience #stem #scicomm
Stephen Schneider helped show that humans are active contributors to changes in the climate system. He was a key figure in the success of the Intergovernmental Panel on Climate Change and an adviser to eight U.S. administrations. He embraced the power of climate modeling and, after finding fault with his own 1971 climate cooling hypothesis due to more data and better models years later, he published what his mistakes had been. In 2007, he shared the Nobel Peace Prize with former Vice President Al Gore “for their efforts to build up and disseminate greater knowledge about man-made climate change”. bit.ly/NASschneider

Easter Island is one of a number of island nations that will increasingly lose access to fresh water over the course of the century. A study looking at 80 groups of small islands found that 73% of them will become more dry. They have previously been overlooked in climate models because of their size.

Aerial footage captured by a drone shows the permafrost in northern Norway beginning to thaw, forming small lakes. The image was taken by a team of scientists who are studying the affect that the melting of this frozen soil can have on the climate. As the permafrost thaws it unlocks large amounts of the greenhouse gases carbon dioxide and methane.
...
Their research suggests that allowing global temperatures to rise to 2C, rather than capping warming at 1.5C, could cost us an area of permafrost the size of Mexico.

In this modeled scenario, carbon dioxide levels rise to 936 parts per million. For reference, we are at 405 ppm currently. As you can see in this movie, this increase has a dramatic impact on the temperature. Areas that are red are warmer than the 20th century average and blue areas are cooler.  #noaa #scienceonasphere #carbondioxide #climatechange #climatemodel #ipcc #rcp8.5 #science
This is a very interesting Instagram post from NASA (a repost from @nasaclimatechange)! According to NASA scientists know today that half of the greenhouse gases that are released by human activites are absorbed by the Earth's ecosystems and that the rest stays in the atmosphere. Of those 50% of the greenhouse gases that are absorbed 25% are absorbed by the vegitation on land and 25% by the ecosystems in the oceans. These facts shows how big the problem is and that it is possible to stop the Global Warming by cutting down hour greenhouse gas emissions. This gives at least some hope for the future. 🌍🤓
