Retired General: 'Our Bases and Stations on the Coast Are Going Underwater'

Tangier Island's coast, with rising waters

This past July, in a Congressional hearing on “The Status and Outlook for U.S. and North American Energy and Resource Security,” retired Marine Brigadier General Stephen A. Cheney offered a dire warning for many current military bases in coastal locations.  

From the tactical side our bases and stations on the coast are going underwater. Norfolk [in Virginia] is the prime example. It’s closed dozens of times a year now because of flooding both from rain and sea level rise,” Cheney explained. “We’re going to have to talk about relocation of our bases and stations that are on the coast.”

Cheney also made it clear that he believes in climate change.

Curbing Climate Change: Why It's so Hard to Act in Time

Climate change action sign in front of Capitol at March for Science

This summer I worked on the Greenland ice sheet, part of a scientific experiment to study surface melting and its contribution to Greenland’s accelerating ice losses. By virtue of its size, elevation and currently frozen state, Greenland has the potential to cause large and rapid increases to sea level as it melts.

When I returned, a nonscientist friend asked me what the research showed about future sea level rise. He was disappointed that I couldn’t say anything definite, since it will take several years to analyze the data. This kind of time lag is common in science, but it can make communicating the issues difficult. That’s especially true for climate change, where decades of data collection may be required to see trends.

A recent draft report on climate change by federal scientists exploits data captured over many decades to assess recent changes, and warns of a dire future if we don’t change our ways. Yet few countries are aggressively reducing their emissions in a way scientists say are needed to avoid the dangers of climate change.

While this lack of progress dismays people, it’s actually understandable.

New Hampshire Climate Denier’s Work Has Powerful New Audience: His Brother, the Governor

Left, Michael Sununu. Right, Chris Sununu

Michael Sununu, a lobbyist, consultant, and businessman from New Hampshire, has for years been voicing doubt about the science behind human-induced climate change. Just last November, for instance, he claimed in an op-ed for a major New Hampshire newspaper that climate scientists “fudge the data for their agenda” as “Mother Nature is still driving climate change.”

With clients in the energy and utility sectors, it would perhaps be easy to dismiss Sununu’s views as interest-based and financially motivated. In the past he even led an energy start-up based on coal. 

But this vocal climate science denier is suddenly in a unique position to influence public policy. His brother, Chris Sununu, now occupies New Hampshire’s highest office — governor. 

PHOTOS: Louisiana’s Oil and Gas Industry Continues Growing Along the Coast It’s Helping Shrink

Strips of coastal Louisiana land eroding into the sea.

The Louisiana coast loses a football field’s worth of land every 38 minutes. This staggering rate of land loss has been brought on by climate change and coastal erosion accelerated by human activities, including water diversion projects and damage done by the oil and gas industry. 

It is also a problem that is best seen from the sky. Thanks to the nonprofit conservation organization SouthWings, I was able to photograph the state’s troubled coast for DeSmog during a flight on November 15, 2016. 

Sea-level Rise Has Claimed Five Whole Islands in the Pacific: First Scientific Evidence

Sea-level rise, erosion and coastal flooding are some of the greatest challenges facing humanity from climate change.

Recently at least five reef islands in the remote Solomon Islands have been lost completely to sea-level rise and coastal erosion, and a further six islands have been severely eroded.

Glaciers in Canadian Rockies Could Shrink By 95% by 2100, Study Finds

Athabasca Glacier

This blog originally appeared on Carbon Brief.

The Canadian Rockies, which sit as a backdrop to many a stunning vista, could be almost entirely devoid of glaciers by the end of the century, a new study suggests.

Researchers modelled the impact of rising temperatures on glaciers across western Canada.

The results show widespread ice loss by 2050, and ice all but vanishing a few decades later.

Around 27,000 square kilometers of Western Canada is covered by glaciers, an area similar in size to the amount of ice in the Himalayas or the whole of South America.

Social Cost Of Carbon Drastically Underestimated: Report

The U.S. government could be drastically underestimating how much climate change is going to cost us, according to a study published by Stanford researchers in the journal Nature Climate Change.

The researchers concluded that the Obama Administration is using a Social Cost of Carbon estimate that may be just one-sixth of the true cost—and that the true cost is high enough to justify aggressive measures for lowering emissions enough to limit global temperature rise to the 2 degrees Celsius that scientists tell us is the threshold for averting catastrophic climate change.

The Social Cost of Carbon is an official estimate of how much economic damage will be caused per metric ton of carbon emitted into our atmosphere—damages like lower crop yields and higher healthcare costs. It is used by the EPA and other federal agencies to calculate the benefits of policies intended to improve energy efficiency, lower emissions, and combat climate change. It is also often used to justify not taking action if the proposed action would cost more than the damage it is intended to mitigate.

The Obama Administration raised its official estimate of the economic cost of a metric ton of CO2 from $21 to $37 in November 2013. Even back then, however, many experts challenged that estimate as far too low.

According to the team at Stanford, that estimate was way too low—they calculate the true Social Cost of Carbon as $220 per metric ton.

New Report: Who Will Pay for the Costs and Damages of Climate Change?

Canadian oil and gas companies could be liable for billions of dollars of damages per year for their contribution to climate change caused by toxic greenhouse gas emissions, according to a study published Thursday.

The study looked at five oil and gas companies currently trading on the Toronto Stock Exchange — Encana, Suncor, Canadian Natural Resources, Talisman, and Husky — and found they could presently be incurring a global liability as high as $2.4 billion annually.

Climate change is increasingly discussed not as some far-off threat but in terms of current realities,” said the 62-page study — Payback Time? What the internationalization of climate litigation could mean for Canadian oil and gas companies.

Published by the Canadian Centre for Policy Alternatives and West Coast Environmental Law (WCEL), the study found data showing the global financial cost of private and public property and other damage associated with climate change in 2010 has been estimated at $591 billion, rising to $4.2 trillion in 2030.

Australia Sea Level Rise Will Rack Up $200 Billion Bill by 2100

Major coastal cities in Australia, that vast southern continent of perpetual surf, sun and endless barbeques, are facing a climate change bill of more than $203 billion in commercial, industrial and residential assets by the end of this century.

A new report by the Climate Council of Australia, Counting the Costs: Climate Change and Coastal Flooding, has found that coastal flooding and erosion caused by global warming will become a significantly larger problem with a projected sea level rise of 1.1 metres by 2100.

The report found that Australia is highly vulnerable to increasing coastal flooding because its cities, towns and critical infrastructure are mainly located on the coast.

Australia’s infrastructure has been built for the climate of the 20th century, the report said, and is unprepared for rising sea level.

Coastal flooding is a sleeping giant,” the report said, “If the threat of sea level rise is ignored, the projected increases in economic damage caused by coastal flooding are massive.”

Climate Change Could Force Thousands From Small Islands in Less Than a Decade: UN

In less than a decade, climate change-induced sea level rise could force thousands of people to migrate from some small island developing states (SIDS), according to the executive director of the United Nations Environment Program.

The world’s 52 small island developing states (SIDS) increasingly share sea level rise and other escalating environmental threats that are further aggravated by economic insecurities, Achim Steiner added.

What makes this situation even more grievous is that the climate change threats facing many SIDS are by-and-large not of their own making,” Steiner wrote in The Guardian. “Their total combined annual carbon dioxide output, although rising, accounts for less than 1% of global emissions.”
