What the World Would Look Like if All the Ice Melted

What the World Would Look Like if All the Ice Melted
This story appears in the September 2013 issue of National Geographic magazine. The maps here show the world as it is now, with only one difference: All the ice on land has melted and drained into the sea, raising it 216 feet and creating new shorelines for our continents and inland seas. There are more than five million cubic miles of ice on Earth, and some scientists say it would take more than 5,000 years to melt it all. North America The entire Atlantic seaboard would vanish, along with Florida and the Gulf Coast. South America The Amazon Basin in the north and the Paraguay River Basin in the south would become Atlantic inlets, wiping out Buenos Aires, coastal Uruguay, and most of Paraguay. Africa Compared with other continents, Africa would lose less of its land to the ultimate sea-level catastrophe, but Earth’s rising heat might make much of it uninhabitable. Europe London?

What the World Will Look Like 4°C Warmer Micronesia is gone – sunk beneath the waves. Pakistan and South India have been abandoned. And Europe is slowly turning into a desert. This is the world, 4°C warmer than it is now. But there is also good news: Western Antarctica is no longer icy and uninhabitable. This map, which shows some of the effects a 4°C rise in average temperature could have on the planet, is eight years old, but it seems to get more contemporary as it ages (and the planet warms). Few serious scientists doubt that climate change is happening, or that it is man-made. Those on the fact-based side of this argument should realise that continuously bombarding the opposition with doom and gloom is likely to reinforce their resistance to accepting the new paradigm. This map offers an alternative: lots of misery and disaster, but also plenty of hope and solutions. First, the bad news. Orange is not much better: 'Uninhabitable desert'. But there is a flipside.

Government 'tried to bury' its own alarming report on climate change | The Independent The Government has been accused of trying to bury a major report about the potential dangers of global warming to Britain – including the doubling of the deaths during heatwaves, a “significant risk” to supplies of food and the prospect of infrastructure damage from flooding. The UK Climate Change Risk Assessment Report, which by law has to be produced every five years, was published with little fanfare on the Department for Environment, Food and Rural Affairs’ (Defra) website on 18 January. But, despite its undoubted importance, Environment Secretary Andrea Leadsom made no speech and did not issue her own statement, and even the Defra Twitter account was silent. No mainstream media organisation covered the report. One leading climate expert accused the Government of “trying to sneak it out” without people noticing, saying he was “astonished” at the way its publication was handled. It said it largely agreed with experts’ warnings about the effects of climate change on the UK. Reuse content

Don’t Panic – How Humanity Might Survive the Next Million Years Our species is going to go extinct. We may have descendants – a new species, or some sort of post-human meld that we construct ourselves – but the long roll of lost creatures preserved in the fossil record leaves no doubt that extinction is inevitable. But just as the survival of the human lineage is only a vague possibility at this point, our eventual downfall also remains in the realm of the unknown. So far, there have been five absolutely devastating mass extinctions in the history of life on Earth (with a smattering of lesser, but still calamitous, events scattered through time). We’ve drastically altered the Earth’s climate and seas through greenhouse gas emissions, we are spreading invasive species around the world, and we’ve taken a horrifyingly active role in directly destroying a variety of species and ecosystems. Learning from prehistory is one way to outline possibilities of what the future might hold. Some of these examples in the middle section don’t entirely fire. Related

Abrupt glacier melt causes Canadian river to vanish in four days Updated A vast glacier-fed river which flowed from Canada's Yukon territory across Alaska to drain into the Bering Sea has disappeared in just four days, in what scientists believe is the first observed case of "river piracy". High average temperatures in the first three months of 2016 caused a dramatic spike in the amount of meltwater flowing from the Kaskawulsh glacier, carving a deep canyon in the ice and redirecting the flow toward the Alsek River in the south, rather than the north-flowing Slims River. That changed the Slims River from a three-metre-deep, raging torrent to a place where "massive afternoon dust storms occurred almost daily", according to a scientific paper published in the journal Nature Geoscience. "We were really surprised when we got there and there was basically no water in the river," lead author Daniel Shugar said of the Slims River. "We could walk across it and we wouldn't get our shirts wet."

Digitala kartor och källkritik Digitala kartor förändrar undervisningen Den digitala tekniken har fullständigt revolutionerat användningen av kartor, inte minst inom skolans undervisning. Tidigare var vi lärare hänvisade till de väggkartor som råkade finnas i klassrummet, de kartböcker skolan hade köpt in, de kartbilder som fanns i läroböckerna samt de köpta eller egenhändigt tillverkade overhead-bilder vi hade tillgång till. Genom internet och annan digital teknik har både lärare och elever tillgång till ett mycket stort antal kartor från i stort sett hela världen på ett sätt som var helt otänkbart tidigare. Kompletterar de tryckta kartorna Kartor i tryckta böcker (till exempel en skolatlas eller en lärobok) följer oftast en gemensam standard när det gäller layout, färger och symboler, något som underlättar förståelsen. För många lärare är digitala kartor därför ett oumbärligt och mycket berikande komplement till de fysiska kartböckerna, snarare än något som gör de traditionella kartböckerna överflödiga.

SEPA makes real-time rainfall data available online Real-time Scottish rainfall data is now available on SEPA’s website. The site provides rainfall information for over 270 locations across Scotland. This may be helpful for a wide range of uses such as flood forecasting, farming, angling and canoeing. Each gauge is represented by a dot on a map which can be clicked to reveal the gauge name and rainfall amounts in a range of hourly, daily, monthly and annual formats. There is also the ability to search by station name. In addition to running these intensity gauges linked by telemetry, SEPA also manages a network of manually read storage gauges operated by public volunteers. Richard Brown, SEPA’s Head of Hydrology, said: “We’re releasing this rainfall beta test site so people can look at the data, use it, and give us feedback on how useful it is and what we could do to improve it.

Sorry, Y’All—Humanity’s Nearing an Upgrade to Irrelevance Humanity has had astonishing success alleviating famine, disease, and war. (It might not always seem that way, but it’s true.) Now, Homo sapiens is on the brink of an upgrade—sort of. wired: In your book you predict the emergence of two completely new religions. Harari: Techno-humanism aims to amplify the power of humans, creating cyborgs and connecting humans to computers, but it still sees human interests and desires as the highest authority in the universe. Dataism is a new ethical system that says, yes, humans were special and important because up until now they were the most sophisticated data processing system in the universe, but this is no longer the case. How so? Take Google Maps or Waze. What does this mean for Homo sapiens? We become less important, perhaps irrelevant. Does the shift toward Dataism matter for politics? In the 20th century, politics was a battleground between grand visions about the future of humankind. Who can make sense of it? Can we opt out?

From recycled art projects to farming simulations, here’s how to roll out the green carpet in your classroom on Earth Day this year. 1. Your middle schoolers know that drinking plenty of H2O is good for them, but they may not realize the impact all those plastic water bottles have on the environment. In this project-based learning unit, they’ll design their own solutions for this issue by using engineering. Bonus: The lessons are aligned with the NGSS Engineering Design Standards. 2. In this art activity, students learn how to take their ideas from paper to reality. Through videos, activities, and lessons, students learn about the importance of recycling. 3. This lesson helps kids understand what could happen to plants and animals if they don’t adapt when their environment changes. 4. How much energy do we consume simply by living our daily lives?

Gis gör kartan konkret – Här ska det ligga en båtkrog. Folk ska kunna komma hit med båt och äta. Felix Wigström, Jonas Wachster och Sara Düsing pekar ut den vackra platsen på udden där deras restaurang ska ligga. Krogen ska vara öppen sommartid och leveranserna ska ske med båt. De undersöker väderstrecken, var kommer solen att vara? De måste också kolla vattenkvaliteten i viken innan de bestämmer sig definitivt. Det är ett liv och ett kiv i Vinterviken, denna soliga dag i början av maj. En flock paddor har också spritt ut sig över parken. – Anteckna hur det ser ut och hur ni känner, att ha som stöd. Den här eftermiddagen är han och kollegan Åsa Colliander Celik ute tillsammans med 7C och 7E. Platsen är känslig för översvämningar och ligger vid Mälaren, en vattentäkt med oviss framtid. – Det är dricksvatten, man vill inte ha in saltvatten, svarar en pojke. Hemma i klassrummet har eleverna tittat på digitala kartor och försökt se var det kan passa att bygga. Många gis visualiserar tidsperspektiv. Samarbetar.

Arctic stronghold of world’s seeds flooded after permafrost melts | Environment It was designed as an impregnable deep-freeze to protect the world’s most precious seeds from any global disaster and ensure humanity’s food supply forever. But the Global Seed Vault, buried in a mountain deep inside the Arctic circle, has been breached after global warming produced extraordinary temperatures over the winter, sending meltwater gushing into the entrance tunnel. The vault is on the Norwegian island of Spitsbergen and contains almost a million packets of seeds, each a variety of an important food crop. When it was opened in 2008, the deep permafrost through which the vault was sunk was expected to provide “failsafe” protection against “the challenge of natural or man-made disasters”. But soaring temperatures in the Arctic at the end of the world’s hottest ever recorded year led to melting and heavy rain, when light snow should have been falling. But the breach has questioned the ability of the vault to survive as a lifeline for humanity if catastrophe strikes.
