Education and Climate Change PDF By:Fumiyo Kagawa,David Selby Published on 2009-11-12 by Routledge There is widespread consensus in the international scientific community that climate change is happening and that abrupt and irreversible impacts are already set in motion. What part does education have to play in helping alleviate rampant climate change and in mitigating its worst effects? In this volume, contributors review and reflect upon social learning from and within their fields of educational expertise in response to the concerns over climate change. They address the contributions the field is currently making to help preempt and mitigate the environmental and social impacts of climate change, as well as how it will continue to respond to the ever changing climate situation.

Most infectious diseases follow a seasonal cycle that allows germs to spread and infect humans. An abrupt climate change can promote

Scientific evidence indicates recent global climate trends which if remain unchanged or develop further could result in abrupt climate change. Abrupt climate change could result in serious environmental and social impacts. The most serious environmental impact would be the disruption of the natural processes which sustain, feed, and fuel people and nations. The disruption of these natural ecosystem processes could result in the scarcity and/or inaccessibility of vital natural resources like water, food, and energy supplies. Scarcity and/or inaccessibility of vital natural resources could create social and political turmoil and adversely impact regional stability and homeland security. As the US is the largest historical producer of carbon dioxide, the most prevalent of the greenhouse gases, it should reform and adopt policies to adapt to the effects and/or mitigate the onset of abrupt climate change. Failure to take action will leave the US vulnerable to the environmental, social, and political impacts of abrupt climate change and threaten national security and vital US interests.

In recent decades, the Arctic has warmed at over twice the global rate. This Perspective places these trends into the context of abrupt Dansgaard–Oeschger warming events in the palaeoclimate record, arguing that the contemporary Arctic is undergoing comparably abrupt climate change.

There was a period during the last ice age when temperatures in the Northern Hemisphere went on a rollercoaster ride, plummeting and then rising again every 1,500 years or so. Those abrupt climate changes wreaked havoc on ecosystems, but their cause has been something of a mystery. New evidence published this week in the leading journal Science shows for the first time that the ocean's overturning circulation slowed during every one of those temperature plunges - at times almost stopping.

Homestyle Magazine April/May 2023 MAKE PEACE — Curating comfort zones. Words from the editor Alice Lines; What brings you comfort when life changes quickly? I’ve been thinking about this a lot in the past few weeks as devastating back-to-back weather events have ravaged Te Ika-a-Māui/the North Island, robbing people of their loved ones, homes and livelihoods. Its been an abrupt reminder of the attention that desperately needs to be paid to the all-too-real issue of climate change.  When I’m in need of TLC, I sometimes undertake a sort of Q&A with myself – not so much to provide answers to the existential threat as to bolster my emotional preparedness for what life throws at us. For me recently, that’s meant asking myself what I can do to genuinely nurture myself, then actively pursuing those activities.  While editing the issue, I’ve also been uplifted by the creatives we’ve chosen to profile. There’s nothing quite like interviewing artists, designers and changemakers, and nodding along in agreement when they reveal what they’re passionate about. When designer Carina Webb candidly shared that the first collection from her newly established studio Frangere was informed by a tricky time in her life, I felt a surge of admiration for the way she moved herself forward. And when Kowtow creative director Marilou Dadat told me she wasn’t that fond of being in front of the camera by would “do it for Fairtrade cotton”, I knew this was woman who fiercely believes in making a difference.  Even when there’s a lot going on in the world, it’s essential that we try to find moments of peace and calm amongst it all. Perhaps making yourself comfortable and reading this magazine will be that for you.  Edited, designed, and published in New Zealand

Climate change could arrive with startling speed. New research has identified at least 37 "tipping points" that would serve as evidence that climate change has happened - and happened abruptly in one particular region.

Greenhouse gases are responsible for the greenhouse effect which causes abrupt climate change and all of its dire consequences.

“In a recently published paper, an @forestservice scientist and his partners conclude that strategies to increase social and ecological resilience are needed given the potential for abrupt (rather than gradual) climate change. https://t.co/a052qwcobZ”

Since we're in the midst of another abrupt climatic shift right now, it just might be the critical time to heed our planet's red flags.

Abrupt changes in ice core samples and other records indicate dramatic changes in climate occurred at certain points in the past.

About 14,000 years ago, the southwest United States was lush and green, home to saber-toothed cats and mammoths. Meanwhile, the Pacific Northwest was mostly grassland.

Ever since the fossil record began telling us about the mammoths, giant sloths, and other megafauna that walked the earth until about 11,000 years ago, scientists have been trying to solve the mystery of why they vanished.

The Falkland Islands are a South Atlantic refuge for some of the world's most important seabird species, including five species of penguins, Great Shearwaters, and White-chinned Petrels. In recent years, their breeding grounds in the coastal tussac (Poa flabellata) grasslands have come under increasing pressure from sheep grazing and erosion. And unlike other regions of the globe, there has been no long-term monitoring of the responses of these burrowing and ground nesting seabirds to climate change. A rookery of Southern rockhopper penguins (Eudyptes chrysocome chrysocome) nest between a rocky slope and a tussac grassland and bring in nutrients from the ocean directly to the grasses at the Kidney Island National Nature Reserve, Falkland Islands [Credit: Dulcinea Groff] A 14,000-year paleoecological reconstruction of the sub-Antarctic islands led by University of Maine researchers has found that seabird establishment occurred during a period of regional cooling 5,000 years ago. Their populations, in turn, shifted the Falkland Islands ecosystems through the deposit of high concentrations of guano that helped nourish tussac, produce peat and increase the incidence of fire. This terrestrial-marine link is critical to the islands' grasslands conservation efforts going forward, says Dulcinea Groff, who led the research as a UMaine Ph.D. student in ecology and environmental sciences, and part of a National Science Foundation-funded Interdisciplinary Graduate Education Research Traineeship (IGERT) in Adaptation to Abrupt Climate Change (A2C2). The connection of nutrients originating in the marine ecosystem that are transferred to the terrestrial ecosystem enrich the islands' nutrient-poor soil, thereby making the Falkland Islands sensitive to changes in climate and land use. The terrestrial-marine linkage in the Falkland Islands was the focus of Groff's dissertation in 2018. "Our work emphasizes just how important the nutrients in seabird poop are for the ongoing efforts to restore and conserve their grassland habitats. It also raises the question about where seabirds will go as the climate continues to warm," says Groff, who conducted the research in the Falkland Islands during expeditions in 2014 and 2016 led by Jacquelyn Gill, an associate professor of paleoecology and plant ecology in the UMaine Climate Change Institute. "Our 14,000-year record shows that seabirds established at Surf Bay during cooler climates. Seabird conservation efforts in the South Atlantic should be prepared for these species to move to new breeding grounds in a warmer world, and those locations may not be protected," says Groff, who is now a postdoctoral research scientist at the University of Wyoming. In the Falkland Islands, tussac grasslands that form deep peat deposits can be found eroding along some coastlines [Credit: Dulcinea Groff] The UMaine expedition team, which included Kit Hamley, then a master's student in Quaternary studies and a Climate Change Institute Fellow, collected a 476-centimeter peat column from Surf Bay, East Falkland. The 14,000-year record revealed in the undecomposed tussac leaves of the peat column "captures the development of a terrestrial-marine linkage that supports some of the most important breeding colonies of seabirds in the Southern Ocean today," according to the research team, which published its findings in the journal Science Advances. The absence of seabirds at the East Falklands site prior to 5,000 years ago suggests that seabirds may be sensitive to warmer mediated sea surface temperatures, which can impact their food supply, according to the research team. With a warming South Atlantic today, the question is whether the Falkland Islands, about 300 miles east of South America, will continue to be a seabird breeding "hot spot." "Our work suggests that as the Southern Ocean continues to warm in the coming decades, the Falkland Islands seabird communities may undergo abrupt turnover or collapse, which could happen on the order of decades," according to the research team, which, in addition to Groff, Hamley (now a UMaine doctoral student) and Gill, involved Trevor Lessard and Kayla Greenawalt of UMaine, Moriaki Yasuhara of the University of Hong Kong, and Paul Brickle of the South Atlantic Environmental Research Institute, all co-authors on the American Association for the Advancement of Science journal article. The Falkland Islands are at the boundary of a number of potential climate drivers, note the researchers. And P. flabellata peatlands have the world's highest accumulation rates, "providing an unusually high-resolution record capable of recording abrupt change" -- preserved charcoal, seabird guano and pollen data that can be used to analyze fire history, seabird population abundance and vegetation composition, respectively. A rookery of black-browed albatross (Thalassarche melanophris) nest at a windy, exposed tussac grassland on West Point Island, Falkland Islands [Credit: Dulcinea Groff] In the Falklands, where there are no native mammals or trees, settlers introduced sheep in the 17th century. Today, residents make their livelihoods from fishing, sheep farming and tourism. The 14,000-year record from East Falkland revealed that for 9,000 years before the arrival of seabirds, the region was dominated by low levels of grasses, a heathland of ferns and dwarf Ericaceous shrubs. About 5,000 years ago, the researchers say, an "abrupt transition" appears to occur. Concentrations in bio-elements such as phosphorus and zinc increase. Grass pollen accumulation rates skyrocket, indicating the establishment of tussac grasslands within 200 years of the establishment of seabird colonies on the island. Also found in the core: increased accumulation rates of peat and charcoal. It's clear that the addition of seabird populations bringing nutrients from the marine environment to the island drove changes in the terrestrial plant community structure, composition and function, according to the researchers, as well as increased fire activity and nutrient cycling. What remains unclear is what drove the abrupt ecosystem shift, says Gill, one of the world's leading authorities on paleo-ecosystems, including the impacts of climate change and extinction, and the geographical distribution of living things through space and time. At dusk, thousands of seabirds called sooty shearwaters (Ardenna grisea) return to their deep nesting burrows dug into the peat of the tussac grassland at the Kidney Island National Nature Reserve, Falkland Islands [Credit: Dulcinea Groff] "We know seabirds arrived at Surf Bay during a time when the climate was becoming cooler in the South Atlantic, though we still don't know for sure what it was they were tracking. We also don't know where these birds took refuge when climates were warmer, and that's concerning as the South Atlantic gets hotter into the future," says Gill, an NSF CAREER researcher who most recently was named a 2020 Friend of the Planet by the National Center for Science Education. "Our study is also a powerful reminder of why we need to understand how different ecosystems are connected as the world warms," says Gill. "We know that many seabirds in the South Atlantic rely on these unique coastal grasslands, but it turns out that the grasses also depend on the nutrients seabirds provide. Because they rely on ecosystems in the ocean and on land for their survival, seabirds are really good sentinels of global change. We just don't have good long-term monitoring data for most of these species, so we don't know enough about how sensitive they are to climate change. The fossil record can help us fill in the gaps."

In the Atlantic Ocean, a giant 'conveyor belt' carries warm waters from the tropics into the North Atlantic, where they cool and sink and then return southwards in the deep ocean. This circulation pattern is an important player in the global climate, regulating weather patterns in the Arctic, Europe, and around the world. Evidence increasingly suggests that this system is slowing down, and some scientists fear it could have major effects, such as causing temperatures to dive in Europe and warming the waters off the East coast of the United States, potentially harming fisheries and exacerbating hurricanes. (For an over-exaggeration of the potential effects, see the 2004 movie The Day After Tomorrow.)

Climate change may be responsible for the abrupt collapse of civilization on the fringes of the Tibetan Plateau around 2000 B.C. Barley cultivation in Jiuzhaigou National Park hasn't changed much in nearly 2,000 years. The park is located in the Min Shan mountain range, Northern Sichuan in South Western China [Credit: Washington State University] WSU archaeologist Jade D'Alpoim Guedes and an international team of researchers found that cooling global temperatures at the end of the Holocene Climatic Optimum, a 4,000 year period of warm weather, would have made it impossible for ancient people on the Tibetan Plateau to cultivate millet, their primary food source. Guedes' team's research recently was published online in the Proceedings of the National Academy of Sciences. Her results provide the first convincing explanation for why the area's original inhabitants either left or so abruptly changed their lifestyles. They also help explain the success of farmers who practiced wheat and barley agriculture in the region 300 years later. Unlike millet, wheat and barley have high frost tolerance and a low heat requirement, making them ideally suited for the high altitudes and cold weather of eastern Tibet. Guedes argues this made the two crops an important facet of subsistence immediately after their introduction around 1700 B.C. "Wheat and barley came in at the opportune moment, right when millets were losing their ability to be grown on the Tibetan Plateau," Guedes said. "It was a really exciting pattern to notice. The introduction of wheat and barley really enabled Tibetan culture to take the form it has today, and their unique growth patterns may have played a crucial rule in the spread of these crops as staples across the vast region of East Asia." One offshoot of the research: The ancient millet seeds that fell out of cultivation on the Tibetan Plateau as the climate got colder might soon be useful again as the climate warms up. "Right now, these millets have almost become forgotten crops," Guedes said. "But due to their heat tolerance and high nutritional value, they may be once again be useful resources for a warmer future." An archaeological enigma At Ashaonao, Haimenkou, and other archeological sites in the Tibetan highlands, researchers for years had noticed a growing trend. An abundance of ancient wheat and barley seeds found at the sites suggested the crops rapidly replaced millet as the staple food source of the region during the second millennium BCE. The findings were puzzling considering that the scientific consensus of the time was the region's climate would have actually favored millet, due to its shorter growing season, over wheat or barley. The conundrum intrigued Guedes so she dove into the agronomy literature to investigate. She found agronomists tended to use a different measurement than archaeologists to determine whether crops can grow in cold, high altitude environments like the Tibetan Plateau. They used total growing degree days or the accumulated amount of heat plants need over their lifetime rather than the length of a growing season. "My colleagues and I created a new model based off what we found in the literature," Guedes said. "It revealed that global cooling would have made it impossible to grow millet in the Eastern Tibetan Highlands at this time but would have been amenable to growing wheat and barley. Our work turned over previous assumptions and explained why millet is no longer a staple crop in the area after 2000 BCE." Guedes' work points to climate cooling as the culprit behind the collapse of early civilization on the Tibetan Plateau. Ironically, the region is today one of the areas experiencing the most rapid climate warming on the planet. There are some areas in the southeastern plateau where temperatures are 6 degrees Celsius higher than they were 200 years ago. Rapid temperature increase is making it difficult for the region's inhabitants to raise and breed yaks, a staple form of subsistence in the central Asian highlands, and grow cold weather crops, once again endangering their survival. "So now we have a complete reversal and climate warming is having a big impact on the livelihood of smaller farmers on the Tibetan Plateau," Guedes said.
