Generations United to Address Climate Change

To help prepare the next generation to lead climate change efforts at the local, national and international level, Virginia Wesleyan University and The Gunn Group held a half-day conference.  This event helped students and community leaders understand how climate change is altering our environment and what can be done today to mitigate or adapt to these changes. National and local climate change experts and activists shared their knowledge, experiences, and insights. Below is a short video highlighting the conference.

Climate change: Scientists to report on ocean ’emergency’ caused by warming

Melting in Greenland and Antarctica is contributing significantly to sea level rise

It will be the clearest declaration yet on how an overheating world is hammering our oceans and frozen regions. 

Scientists have been meeting in Monaco to finalise a report on the seas and the cryosphere. 

Released on Wednesday, it will show how the oceans have been a friend, helping us cope with rising temperatures. 

But it will warn that warming is turning the seas into a huge potential threat to humanity.

Researchers from the Intergovernmental Panel on Climate Change (IPCC) were encouraged by Prince Albert II and the Monaco government in 2015 to produce a special report on the oceans and cryosphere – the Earth’s surface where water is frozen solid.

For the past three years, the scientists have been reviewing hundreds of published papers on how climate change affects the seas, the poles and glaciers. 

Their report will track the flow of water from the frozen tops of mountains to the bottom of the seas, and how this is changing in a warmer world. 

In 1980, the minimum sea ice extent was 7.7 million square kilometres. This year it was at 4.7 million square kilometres.2012 was the lowest year on record, when it was down to 3.6 million square kilometres - less than half what it was in 1980.

Over the past few days, they have been trying to agree a short summary of their findings with government representatives that will be published on Wednesday. 

It will likely detail the growing threat from rising sea levels that could imperil hundreds of millions of people before the end of this century. 

It will also warn of the threat posed by the growing acidification of the seas, the threats to coral and fisheries and the possibility that warming might melt permafrost, releasing huge amounts of the CO2 gas that’s the key to rising temperatures. 

“At current emissions rates, we are effectively dumping one million tonnes of CO2 into the oceans every hour,” said Melissa Wang, a scientist with Greenpeace. 

“Unless we accelerate efforts to curb carbon emissions and take greater steps to protect our oceans, there will be devastating human, environmental and economic consequences.”

First things first, how are the oceans connected to the climate system?

The oceans are like the big sister that constantly has to bail out her careless younger sibling. Every year, the ocean waters soak up about a quarter of the carbon dioxide emissions that arise from human activities. 

The acceleration in melting of the ice sheet covering Greenland has shocked researchers

Glaciers are now melting all over the world

Since 1970, the oceans have absorbed more than 90% of the extra heat that’s come about through global warming. If they hadn’t taken in that warming, the surface of the planet would have been devastated by excess heating. 

All this absorption has come at a price, though. Our seas are now warmer, less salty and more acidic as a result.

“The reality is that we have been quietly reliant on the ocean to do these things, but there comes a point where the ocean changes because of the scale of what we are doing,” Prof Dan Laffoley, from the International Union to Conserve Nature, told BBC News. 

How is warming changing our relationship with the oceans and ice?

The heating of the world is having a profound impact on all things frozen. So the IPCC report will look at the loss of ice from the Greenland and Antarctic ice sheets as well as from glaciers on mountains around the planet. 

It will chart the rise of CO2 that is making the waters more acidic and more difficult for sea life. It will also link the warming to the rise of “superstorms”. 

One of the big changes has been in the impact of warming on the Greenland and Antarctic ice sheets, which has grown substantially in recent decades. 

These frozen regions are critically important for global sea levels, which impact flooding around the world. 

As documented by my colleague David Shukman, this year has been one of record melting on the gigantic frozen island of Greenland. 

In one day alone it lost 12.5 billion tonnes of ice.

Antarctica has also enormous capacity to raise the waters around the world. 

According to studies, the amount of ice lost from the vast frozen region increased six-fold per year between 1979-1990 and 2009-2017.

Will this report be all about sea level rise?

It is likely that much of the report will focus on the growing threat posed by rising sea waters. There is an expectation that some of the existing predictions for sea level will be revised upwards, with the threat posed to small island states and large cities increasing substantially by the middle of this century. 

“By the end of this century, and if current adaptation efforts are not substantially scaled up, we must expect high levels of risk on low coasts such as atoll islands like the Maldives, and some Arctic communities even in a low-emission scenario,” said Alexandre Magnan, a research fellow at the policy research institute IDDRI in Paris, and a co-author of the IPCC Ocean Report. Low-lying small island states will be badly hit by sea level rise

“In a higher-emission scenario, even wealthy megacities such as New York or Shanghai and large tropical agricultural deltas such as the Mekong will face high or very high risks.”

The estimations for the centuries beyond 2100 will be even more stark, with suggestions that sea level rise could be 100 times higher than today. The threat of flood damage is likely to accelerate over this century

“What happens with sea level rise is not disconnected with what happens with warming,” said Jane Lubchenco, former administrator of the US National Oceanic and Atmospheric Administration and a co-chair of the expert group of a High Level Panel for a Sustainable Ocean Economy.

“Because the ocean is warming we are getting more intense storms. Because the ocean is rising the impact of storm surge from those storms has much more potential.”

What other impacts on the seas will the report look at?

It will also look at the increase in marine heatwaves – these could increase by a factor of 50 by 2100. This will have big implications for ecosystems and will increase coral bleaching. 

“Extreme sea level events, such as surges from tropical cyclones, that are currently historically rare, for example today’s 100-year event, will become common by 2100 under all emissions scenarios,” said Jean-Pierre Gattuso, an IPCC author and a CNRS research scientist at Sorbonne University. 

“This will have major consequences for many low-lying megacities and small islands.”

However, the report will also look at ocean acidification and will show how climate change is changing the balance. 

There will also be sections on coral reefs and there will also be a focus on fishing and fish stock, which are likely to suffer dramatic declines. 

What about glaciers and frozen regions?

For people living in the Himalayas and the Hindu Kush, a warmer future means that at first they will get too much water from glaciers as they melt. Then there will be too little. The melting of permafrost could add billions of tonnes of CO2 to the atmosphere

report last year stated that two-thirds of these giant ice fields could disappear by the end of the century without rapid emissions cuts. This could have huge implications for the millions of people living in the region.

The IPCC report will also document the threat posed by warming to permafrost.

Some 30-99% of the Northern Hemisphere’s permanently frozen soils could melt by the end of the century, freeing up billions of tonnes of CO2 which could in turn accelerate warming to a new, ever more dangerous level. 

Surely there are some positives in this report?

Yes – the report will also show that the oceans could hold some important solutions to the threats posed by climate change. 

There is great scope for renewable energy systems based on the oceans, while cutting carbon from shipping would be a major step forward. Planting more mangroves and sea grass could remove huge amounts of CO2 from the atmosphere. 

Even the potential to switch diets to get more of our protein from the oceans would likely help cut carbon.

Thinking about Moving to Florida? Then you need to read this.

An Investment Expert Says Florida Homeowners Should Sell Property Now As Climate Impacts Worsen

By Jessica Weiss  May 24, 2019 

A biker in Miami.

An expert on the impact of climate change on financial markets has advice for anyone thinking of buying a home in Florida: don’t.

Spencer Glendon of the Woods Hole Research Center said Friday on the Florida Roundup that financial institutions are going to wreck Florida’s economy if they don’t confront the risk to coastal real estate and slow their lending. He warned that home buyers in the state should no longer be receiving 30-year mortgages.

“What maybe seemed like a long time horizon or something that’s far away actually isn’t far away,” Glendon said. “The longer we wait to start adjusting, the more painful it will be.”

Insurability is the main issue. Thirty-year mortgages come with the condition that a borrower have insurance, which is renewed annually. But insurers can choose to stop offering insurance at any time, or make prices prohibitively expensive, which would cause a homeowner to violate their debt. Eventually, lenders would be forced to stop lending, causing prices to plummet. 

In Florida, where many parts of the state are increasingly under risk of flooding and infrastructure erosion, both insurance companies and reinsurance companies have begun to sound the alarm and suggest they will not be working in Florida markets in the coming years.

“Things that are a 1 in 20 year event, or a 5 percent risk, are essentially uninsurable in most parts of world. That’s too often for an insurance company to want to intervene and have to want to deal with claims,” he said. “In most of coastal Florida, that threshold has already been breached.”

Meanwhile, thousands of people continue to move to Florida each week, many of them within 50 miles of the coast — where risk is highest for disaster from rising waters. The state is currently home to some 21 million people. 

Kevin McCarty, the chairman of the Florida Association for Insurance Reform and Florida’s former insurance commissioner, said on The Florida Roundup that banks aren’t likely to stop lending in Florida anytime soon — “unless something happens dramatically to shift the burden to [them] to actually have to pay.”

He compared the threat of sea-level rise in Florida to earthquakes in California.

“It’s interesting because there’s a huge number of homes in California that are provided mortgages that don’t have earthquake coverage … Millions and millions worth of mortgage property on fault lines that don’t have simple protection,” he said. “We know earthquakes are going to happen in California and when it happens it will be devastating. Yet the mortgage industry continues to provide.”

McCarty agreed that Florida has failed to sufficiently address sea-level rise and climate change.

“There have been some efforts made at the local level, particularly in southeast Florida,” he said. “But the state has not made a comprehensive effort to address that. We need to make communities more resilient and therefore more insurable.”

Glendon recommended a more dramatic approach, and encouraged people to start preparing now for the future, such as by paying down mortgages and/or selling.

He called for climate change and adaptation to be taken up on the local and state level and by Congress.

“If we start acknowledging some of the misplaced capital now and misplaced expectations now, the adjustment will be easier,” he said. 

Nevada key to advancing national security through clean energy | Gunn

I have the privilege of serving on CNA’s Military Advisory Board — more than 30 retired three- and four-star generals and admirals from the Army, Marine Corps, Navy, Air Force and Coast Guard who study pressing issues of the day to assess the impact of those issues on America’s national security. Energy is one of our top concerns.

Reliable electricity underpins every facet of American lives. Without it, our homes, our businesses and our national security engine would grind to a halt — especially when so much of this power is becoming “smart” and integrated. Yet the nation’s electrical generation and distribution infrastructure, commonly referred to as “the grid,” is showing its age and vulnerability — no wonder, since the grid was conceived more than a hundred years ago.

We’ve studied the risks to our grid and worked hard to identify policies that can mitigate them. Our key findings are found in our reports “National Security and Assured U.S. Electrical Power” and “Advanced Energy and U.S. National Security,” both available for free at

I recently had the opportunity to meet with a number of Nevada’s legislators and to present our key findings to the Assembly’s Growth and Infrastructure Committee. This was my fourth visit to Nevada over the last three years to speak with state agencies, legislators and other elected officials concerned with these issues. I’m pleased that Nevada has demonstrated leadership in enacting policies that diversify energy supply, expand the distributed generation of electricity and provide incentives for energy storage.

There’s more that needs to be done. Fortunately, your 2019 Legislature is also discussing forward-thinking actions on clean energy such as a stronger renewable energy portfolio standard and the electrification of transportation. These and other policies will increase Nevada’s leadership in clean, advanced energy in a way that benefits Nevadans and demonstrates a model for other states. Such policies enhance our national security.

More: Russians are hacking our electric grid. Where’s the urgency on this escalating threat?

More: All the selfish reasons we need an anti-oil foreign policy. It’s not just about climate.

We find ourselves at a unique point in history. On one hand, we have an aging grid with increasing vulnerabilities and determined adversaries. On the other hand, we have advancing technologies and proven, innovative sources that are much more capable of producing electrical power closer to the consumer. We have the technology to build a grid that is more resilient and much less of a strategic target for adversaries, and at the same time will be more flexible and able to accept future technological advances in energy production. Because our adversaries are determined and the threats to our electrical grid and national security are real and substantial, we believe that the time to fix the issues with our grid is now.

Nevada has already shown that it’s willing to be at the forefront of innovation and problem-solving. I urge Nevada’s policymakers to seize this challenge and opportunity. In 1864, Nevada became the “Battle Born” state with the development of its silver resources helping preserve our nation and advance freedom. Leadership in the 2019 legislative session that accelerates the development of Nevada’s clean energy resources has the potential to significantly improve our national system of generating, storing and delivering electrical energy while advancing the security of the United States and demonstrating American leadership to the world.

Lee invited to Nevada to discuss advanced energy technologies

Last week, Lee as a member of the Center for Naval Analysis Military Advisory Board was invited to speak to the National Security Forum of Northern Nevada. He also briefed the Nevada Legislature’s Senate Committee on Growth and Infrastructure on how the development of advance energy infrastructure and national security are connected.
