A carbon paw-print. Read more. Battling Arctic invaders may sound like a game, but it's one of the biggest threats to our environment. Efforts to control invasive species face a list of significant issues over the next two decades, say ecologists.
“Environmental, biotechnological, and sociopolitical trends are transforming risks of invasion worldwide. We have identified some potential game-changers,” says McGill University professor Anthony Ricciardi, who led the study in Trends in Ecology and Evolution. Here are five of the major risks the group identified: 1. Arctic invaders Until now, the Arctic has been among the least accessible regions on the planet, escaping extensive and devastating alien species invasions like those that have struck temperate and tropical areas of the world. But the rapid loss of sea ice is opening the region to shipping, oil, and mineral extraction, fishing, tourism, and shoreline development—all of which facilitate introductions of alien species. 2.

By Max Fisher By Max Fisher October 9, 2013 Climate scientists sometimes talk about something called "climate departure" as a way of measuring when climate change has really changed things.
It's the moment when average temperatures, either in a specific location or worldwide, become so impacted by climate change that the old climate is left behind. It's a sort of tipping point. And a lot of cities are scheduled to hit one very soon. Sundaland: Coastlines of the Ice Age. This map shows how the terrain may have appeared during the Last Glacial Maximum, around 21,000 years ago, when sea levels were approximately 125 meters (410 feet) below present.
This map does not include any lakes of this time period. *****Bioluminescence: Tasmania's coastline glows in the dark as plankton turn blue. The waters along Tasmania’s north-west coastline have taken on a bizarre, glowing appearance in recent days.
Photographs taken off Preservation Bay and Rocky Cape showcase bioluminescent waters caused by Noctiluca scintillans (AKA sea sparkle), tiny plankton emitting blue light in self-defence. The phenomenon, which is best seen in calm, warm seas, is foreboding. *****SEA-LEVEL RISE: Gentrification fears grow as high ground becomes hot property. MIAMI — One of the first sea-level rise maps Broadway Harewood saw was a few years back, when climate activists gathered in his neighborhood to talk about how global warming would affect people in less-affluent South Florida communities.
Harewood had a realization, one that he illustrates with his hands. One hand represents the city of Miami Beach. The opposite hand, moving like the incoming tide, demonstrates how the seas will eventually rise, potentially bringing the coastline of South Florida closer to Miami's historically black neighborhoods — properties like his investments in Liberty City that sit on comparatively higher ground. *****Failure at seed vault not too bad.

The Antarctic Peninsula is not only getting warmer, it's getting dramatically greener with a sharp increase in plant growth over the past 50 years.
Key points Antarctica Key points The Antarctic Peninsula is one of the most rapidly warming places on EarthUK scientists studied moss cores from sites along the Antarctic PeninsulaThey found a sharp increase in plant growth and microbial activity since the 1950sFindings indicate major changes in the biology and landscape will occur with future warming. Irreversible ocean warming threatens the Filchner-Ronne Ice Shelf. By the second half of this century, rising air temperatures above the Weddell Sea could set off a self-amplifying meltwater feedback cycle under the Filchner-Ronne Ice Shelf, ultimately causing the second-largest ice shelf in the Antarctic to shrink dramatically.
*****Gorgeous #infographic shows how sea level rise might impact cities around the globe (climate change) 'Our country will vanish': Pacific islanders bring desperate message to Australia. “Like a drop of water in a bucket, on its own is small, but if there are many, many drops, soon it is overflowing.”
Erietera Aram’s water analogy is apposite. His country faces being lost under the waves of the Pacific Ocean. The i-Kiribati man is in Australia delivering his message about the reality of climate change in his country, and of its immediacy. Each discussion, he says, is like a drop of water, adding to the one before it, slowly building understanding of the existential threat to his people and place.

US Glacier national park losing its glaciers with just 26 of 150 left. It’s now “inevitable” that the contiguous United States will lose all of its glaciers within a matter of decades, according to scientists who have revealed the precipitous shrinkage of dozens of glaciers in Montana. Warming temperatures have rapidly reduced the size of 39 named glaciers in Montana since 1966, according to comparisons released by the US Geological Survey (USGS) and Portland State University.
The Doomsday Glacier - Rolling Stone. In the farthest reaches of Antarctica, a nightmare scenario of crumbling ice – and rapidly rising seas – could spell disaster for a warming planet. Thwaites Glacier in West Antarctica is so remote that only 28 human beings have ever set foot on it. Knut Christianson, a 33-year-old glaciologist at the University of Washington, has been there twice.
A few years ago, Christianson and a team of seven scientists traveled more than 1,000 miles from McMurdo Station, the main research base in Antarctica, to spend six weeks on Thwaites, traversing along the flat, featureless prairie of snow and ice in six snowmobiles and two Tucker Sno-Cats. "You feel very alone out there," Christianson says.

RHS Gardening in a Changing Climate report. *****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. If we continue adding carbon to the atmosphere, we’ll very likely create an ice-free planet, with an average temperature of perhaps 80 degrees Fahrenheit instead of the current 58.
North America. Life on Earth is getting a major redistribution, and the consequences are serious. Last year in Paris, for the very first time, English sparkling wine beat champagne in a blind tasting event. Well established French Champagne houses have started buying fields in Britain to grow grapes, and even the royal family is investing in this new venture. At the same time, coffee-growing regions are shrinking and shifting. Farmers are being forced to move to higher altitudes, as the band in which to grow tasty coffee moves up the mountain. *****Increased hail, wind damage, tornadoes: Severe weather reports tally 5,000+ so far in 2017, more than double the average to date. As coral on Great Barrier Reef bleaches for second year in a row, a reminder of sea temperature trends in the region. Huge fleet of icebergs hits North Atlantic shipping lanes. More than 400 icebergs have drifted into the North Atlantic shipping lanes over the past week in an unusually large swarm for this early in the season, forcing vessels to slow to a crawl or take detours of hundreds of kilometres.
Experts are attributing it to uncommonly strong counter-clockwise winds that are drawing the icebergs south, and perhaps also global warming, which is accelerating the process by which chunks of the Greenland ice sheet break off and float away. As of Monday, there were about 450 icebergs near the Grand Banks of Newfoundland, up from 37 a week earlier, according to the US Coast Guard’s international ice patrol in New London, Connecticut. Those kinds of numbers are usually not seen until late May or early June. *****Cartoma - Map Design & Spatial Analysis. *****#Map visualises scenario were all sea ice melted and #Europe was flooded dramatically.

Shoppers afflicted by the “courgette crisis” are facing further privation, as supermarket chains Morrisons and Tesco imposed restrictions on the number of lettuces that can be bought by each customer. Tesco has introduced a three-lettuce limit on icebergs while rival Morrisons has imposed a two-lettuce limit and banned shoppers from buying more than three heads of broccoli. The UK’s largest retailer posted signs on its salad sections which stated: “Due to continued weather problems in Spain, there is a shortage on iceberg lettuce. To protect the availability for all our customers, we are limiting bulk purchases to three per person. Antarctic bottom waters freshening at unexpected rate: Shift could disturb ocean circulation and hasten sea level rise, researchers say. Can #climatechange be noticed locally?

When the Soviet Union collapsed, this city – by far the world’s largest settlement within the Arctic Circle – went into steep decline, its population tumbling from nearly half a million to barely 300,000.
Ignoring climate scientists' forecasts about sea level rise could prove 'disastrous', experts warn. Ignoring climate models which predict sea levels could rise by an average of more than two metres by 2100 could prove “disastrous”, two leading US scientists have warned. Writing in the prestigious journal Science, Professor Michael Oppenheimer, of Princeton University, and Professor Richard Alley, of Pennsylvania State University, said building flood defences could take decades so there was a need to prepare.
