Will predicted sea rise inundation and flooding affect property values in Coffs Harbour NSW?

Coffs Harbour 7m rise. Click to enlarge.

As many homes in Coffs Harbour  are flooded because of an intense rain depression we need also to examine the affect of sea rise. 

 

We also must stop building in flood affected areas. Councils must stop approving development in flood affected areas. It is ridiculous to see new buildings flooded to their roofs. Insurance companies may pay for a while but not without future higher payment rates. In the end every taxpayer pays.

 

• We are looking more and more unlikely to prevent severe global heating.

• Scientists are predicting the melting of the ice covering Greenland with a subsequent sea level rise of 7m.

• This rise does not factor in sea rise from the melting of Antarctica and other ice.

• Already many properties are likely to flood when a high tide is combined with high local rainfall. What were a hundred year rainfall events are now ten year events.

• The frequency of high rainfall events will increase with global heating and more and more severe hurricanes are predicted because of warmer seas.

• Low coastal areas will be subjected to severe storm surges.

• Would you buy a property likely to be inundated in twenty years, fifty years, a hundred years? Many wouldn't. Even the perception of possible inundation will greatly affect property values.

• When certain properties are in less demand their value falls.

• Would you buy a property with a value likely to fall?

•  The view of Coffs Harbour above shows areas likely to be inundated by a 7m sea level rise.

• Property above a 10m rise will become highly sought after and will greatly rise in value.

A record hurricane season (excerpt): New York Times

 

Satellite image of the Atlantic on November 10th, 2020. Image: NOAA "Subtropical Storm Theta, which formed in the open waters of the Atlantic this week, became the 29th named storm of this year’s hurricane season, surpassing the total count from 2005. Scientists can’t say for sure whether global warming is causing more hurricanes, but they are confident that it’s changing the way storms behave. Here’s how.

Higher winds. There’s a solid scientific consensus that hurricanes are becoming more powerful. Hurricanes are complex, but one of the key factors that determines how strong a given storm ultimately becomes is ocean surface temperature, because warmer water provides more of the energy that fuels storms.

More rain. Warming also increases the amount of water vapor that the atmosphere can hold. In fact, every degree Celsius of warming allows the air to hold about 7 percent more water. That means we can expect future storms to unleash larger amounts of rainfall.

Slower storms. Researchers do not yet know why storms are moving more slowly, but they are. Slower, wetter storms worsen flooding.

Wider-ranging storms. Because warmer water helps fuel hurricanes, climate change is enlarging the zone where hurricanes can form. That could mean more storms making landfall in higher latitudes, like in the United States or Japan.

More volatility. As the climate warms, researchers also say they expect storms to intensify more rapidly. Researchers are still unsure why it’s happening, but the trend appears to be clear."

Climate Change will bring more severe storms.

"Although scientists are uncertain whether climate change will lead to an increase in the number of hurricanes, warmer ocean temperatures and higher sea levels are expected to intensify their impacts."

How can we prepare for more severe storms? 

"How to Build Resilience

Reducing greenhouse gas emissions is one way to reduce the risk of the strongest storms in the future. Communities can also bolster their resilience to the impacts of hurricanes by:

• Preserving coastal wetlands, dunes, and reefs to absorb storm surges.
• Replenishing beaches and improve infrastructure that affords coastal protection, such as seawalls.
• Elevating vulnerable buildings to reduce flood damage.
• Designing structures to be resilient to high winds and flying debris.
• Enacting policies that discourage development in vulnerable areas.
• Preparing prior to a storm’s arrival by boarding windows, clearing property of potential flying debris, and having an evacuation plan."    https://www.c2es.org/content/hurricanes-and-climate-change/

For Government::

• strengthen regulations to prevent further development and new infrastructure on susceptible coastlines

• ensure emergency services are well prepared and supported financially

• support people in developing emergency plans

• ensure the vulnerable can access support

• financially support smaller nations unable to prepare sufficiently for storms

With Climate Losses Rising, Central Banks Push Greener Finance: Bloomberg

Weather related catastrophes are increasing

"The measures are aimed at building awareness about the potential losses as global temperatures increase, making storms more powerful and weather less predictable. It’s also seeking to encourage funding for greener projects that would reduce emissions and make renewables more affordable.

“If some companies and industries fail to adjust to this new world, they will fail to exist,” Carney and Villeroy said in a Guardian newspaper article on Wednesday. They warned that a “massive” reallocation of capital was necessary to prevent global warming, with the banking system playing a pivotal role."

A record share of Australians say humans cause climate change: poll: SMH

More Australians than ever believe human activity is entirely or mainly responsible for climate change, new polling shows.

But only 13 per cent say the Morrison government is doing a good job tackling climate change.

A survey by social research firm Ipsos shows 46 per cent of Australians now agree climate change is “entirely or mainly” caused by human activity. That is the highest share since Ipsos began asking the question in an annual survey of Australians’ attitudes to climate change in 2010.

How affected will Macksville NSW be by a 7m sea rise? Quite affected.

• Would you buy a property likely to be inundated in twenty years, fifty years, a hundred years? Many wouldn't. Even the perception of possible inundation will greatly affect property values. Insurers are already reluctant to insure many properties that were once only likely to flood every 100 years.

• When certain properties are in less demand their value falls.

• Would you buy a property with a value likely to fall?

•  The view of Macksville above shows areas likely to be inundated by even a 7m sea level rise. Note the flooding of infrastructure and roads. Water supply will be affected. How could levees hold back such an onslaught?

• Property above a 10m rise will become highly sought after and will greatly rise in value. Property able to be accessed by road will increase in value but properties isolated by sea rise will lose value. New, costly road routes above the Nambucca River floodplain will be required. Will NSW be able to afford to update all its infrastructure?

IPD Article: The Criminal Dimension of Climate Change

A new book titled Unprecedented Crime: Climate Science Denial and Game Changers for Survival, by Dr. Peter Carter and Dr. Elizabeth Woodworth, with a forward by the leading climate scientist Professor James Hansen outlines the criminality of those who actively promote the continuing emission of carbon gases into the atmosphere with full knowledge of the consequences, including the breakdown of the large ice sheets, sea level rise and intensification of extreme weather events such as hurricanes, floods and fires around the world.

The book highlights the collusion of a large part of the media with climate change denial and cover ups, stating: “There is no benign explanation for a full media blackout of a significant global development that was heralded by the United Nations Secretary-General. This blackout goes far beyond ignorance or negligence. It is a willful obstruction of public knowledge of the extraordinary extent of global efforts to combat the greatest existential threat of all time by changing business-as-usual. We define this willful, methodical blocking of vital survival information as an unprecedented crime against life on the planet.”
