Alaskan Glaciers are Melting and Adding to Sea Level Rise

In Alaska unprecedented heat is melting glaciers and causing sea levels to rise. According to a new study the amount of water from melting glaciers could cover the entire state of Alaska in a foot of water every seven years. This is the finding of the authors of a study called "Surface melt dominates Alaska glacier mass balance," published in the peer-reviewed Geophysical Research Letters, a journal of the American Geophysical Union.

Video - Arctic Emergency: Scientists on Melting Arctic Ice



In this video climate scientists address how rising temperatures in the Arctic are contributing the melting sea ice, thawing permafrost, and destabilization of a system that has been called "Earth's Air Conditioner". They make the point that global warming is here and is impacting weather patterns, natural systems, and human life around the world - and the Arctic is central to these impacts.

Event - The Sustainability of Delta Cities (Debate)

A debate on the ‘Sustainability of Delta Cities’ will take place on June 4,2014 in Rotterdam, The Netherlands. The debate will look at how we can better exploit what we know about land subsidence in urban areas. The speakers will examine the links between planning, design and construction in delta cities using Jakarta, New Orleans and the Green Heart of the Netherlands as examples.

Delta cities are facing long-term problems such as land subsidence, climate change and rapid rises in the population. Jakarta, New Orleans or Gouda: they can all look forward to major challenges.Land subsidence is a slow and lengthy process that today’s cities are not built to cope with.It is a problem that has not been adequately understood by urban planners, landscapers and architects. For these groups, Deltares will organise a debate on Wednesday 4th June, in the Kunsthal in Rotterdam.

Balken Flooding and the Costs of Climate Change

Much of the former Yugoslavia (Serbia, Bosnia and Croatia) is under water and hundreds of thousands of buildings are inundated across the region. Some of the worst flooding ever experienced in the area has killed almost 50 people and triggered more than three thousand landslides.

Hundreds of thousands of people have been evacuated and millions of people are affected. People all across the region are cut off with no water, food, power or communications. The floods are exposing some of the more than one hundred thousand mines and driving the biggest mass migration in the Balkans since the war in the 1990s.

Antarctic Glaciers Pass the Point of No Return

A recent report concludes that Antarctica's ice sheet has reached a tipping point from which it will not be able to recover. Scientists predict that the glaciers in the western part of Antarctica will melt and raise sea levels by four feet or 1.2 meters. These sea level rises will displace tens of millions of people from coastal areas around the world.

As explained by NASA glaciologist Eric Rignot, the glacial retreat "appears unstoppable." Rignot is the lead author of a joint NASA-University of California Irvine paper that used 40 years of satellite data and aircraft studies to come to the conclusion that Antarctic glaciers are now "past the point of no return."

The rate at which the area's ice is melting has increased 77 percent since 1973. According to researchers the melting is being precipitated by warmer ocean currents which have begun a chain reaction. Although first observed around glaciers in the Amundsen Sea-area, the effect is expected to spread to other Antarctic glaciers.

Implications of Arctic Heat: Less Ice and More Global Warming

The Arctic continues to warm and ocean sea ice continues to retreat at an alarming pace. This has dramatic implications that are both global and local. Arctic ice has been both retreating and thinning in volume for four decades.

As reported in the Ecologist, the latest study by Stroeve et al. from the University College London, was published in Geophysical Research Letters. This study shows that the ice-free period is increasing by 5 days every decade. In some regions of the Arctic, the autumn freeze is now up to 11 days later every decade.

The research examined satellite imagery of the Arctic for the last 30 years. They found that the ice is melting and the increasing exposure to sunlight means that greater quantities of energy are being absorbed by the Earth.

Alaska's Record Breaking Heat in January Offers More Evidence for a Dramatically Warmer Arctic

While the continental US was being slammed with a succession of cold spells and winter storms in January, Alaska was experiencing some of the hottest temperatures ever recorded for the month. Temperatures were as much as 40°F (22°C) above normal. The all-time warmest January temperature ever observed in Alaska was tied on January 27 when the temperature peaked at 62°F (16.7°C) in Port Alsworth.

The NASA map (above left) shows the temperature anomalies in Alaska for January 23–30, 2014. Those areas which experienced higher than average temperatures compared to the 2001–2010 average for the same week are highlighted in red. The map is based on data from Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite.

Save the Arctic from a "Death Spiral"

In last 30 years, we’ve lost as much as three-quarters of the floating sea ice cover at the top of the world. Satellite images reveal that the volume of that summer sea ice in the Arctic has shrunk so fast that scientists say it’s now in a ‘death spiral’. Due to human activities, primarily the burning of fossil fuels, the Arctic may soon be ice free in the summer for the first time in over 800,000 years.

This will be devastating for polar bears, narwhals, walruses and other species that live there. It will also have profoundly destructive consequences for people all around the world as the Arctic helps to regulate global weather patterns and as a consequence has a powerful impact on global agriculture.

Video - Watch the Disintegration of the Largest Glacier Ever Recorded on Film



Glaciers are melting at an ever expanding rate all around the world and this video documents the disintegration of the largest glacier ever recorded on film. This glacier has ice spires that are two or three times taller than the tallest buildings in New York City. In the last ten years it has retreated more than in the previous century.

Kitchener/Waterloo's Climate Change Action Plan

Late in November, 2013, Kitchener city council unanimously endorsed Waterloo Region's first-ever climate change action plan. The plan will reduce greenhouse gas (GHG) emissions by six percent from our 2010 levels by 2020. Waterloo and Cambridge Councils did the same earlier this month.

The Costs of Flood Damage will Rise Along with Sea Levels

Flooding is a very expensive corollary of global warming. While we cannot connect individual weather events directly to global warming, the storm that hit Europe in early December is nonetheless a powerful reminder of what the future will look like as the world continues to warm. Much of the billion dollars worth of damage caused by Xaver is due to flooding caused by storm surges.

As global warming continues and ice keeps melting, sea levels will keep rising which will increase the damage caused by storm surges. A warmer planet not only increases the volume of sea water, it is also expected to increase precipitation in places that need it least. As reported by 350.org, global warming has already raised global sea level about 20 cm since 1880, and the rate of rise is accelerating. Scientists expect roughly 60 to 210 more cm of sea level rise this century, depending on whether or not we can limit greenhouse gas emissions (GHGs).

Flooding is a very costly phenomenon. A 2013 study in Nature concluded that flooding could cost the world’s cities $60 billion a year, even with major investments in flood protection. If we don’t make those investments, the cost could be up to $1 trillion a year.

Video - Richard Branson on the Need to Protect the Arctic


In this video, Richard Branson, explains why we all have to do everything within our power to protect the Arctic.

Video - The Arctic is Under Threat from Shell and Gazprom


The fossil fuel companies Shell and Gazprom have ambitious plans to exploit the Arctic's oil and gas reserves. Scientists have made it clear that to avoid the worst impacts of a hot planet (ie 6 degree temperature increase) we must leave the vast majority of carbon reserves underground. Arctic drilling increases global warming and imperils Arctic ecology. We know that drilling for oil and gas inevitably leads to spills. To make matters worse Gazprom's old and outdated drilling equipment present an elevated level of risk. Drilling in the Arctic will devastate the region's fragile ecosystem which is already suffering from a warming world.
