SF doesn’t know which neighborhoods will be worst hit after a given storm, but they do know sea levels are rising, and that with climate change, those hurricanes off Mexico’s Pacific Coast could come north some day. They don’t know when or how severe, but we could get a 25 foot storm surge at some point.
In San Francisco (SF), where the waterfront has been a political battleground for decades, sea-level rise is too easy to ignore.
While SF is less vulnerable to rising sea levels than other parts of the Bay Area, portions of areas bordering the bay would be at risk.
The challenge is to accommodate the bay’s impending expansion as it rises because of our warming planet. And to accomplish that in a way that won’t put our human and environmental resources at risk. Read More
COP21: Rallies call for Paris climate change action
Will the negotiations in Paris lead to an international climate agreement? The question seems not to be whether the negotiations lead to an agreement but what bottom line, the results of the agreement will be.
Five questions about the climate issues. Read More
Berkeley Earth has just released analysis of land-surface temperature records going back 250 years, about 100 years further than previous studies. The analysis shows that the rise in average world land temperature globe is approximately 1.5 degrees C in the past 250 years, and about 0.9 degrees in the past 50 years.
With 195 participating countries and 3000 journalists we can expect a lot of news from Paris during the next days.
In advance, a summary of the top in figures. Read More
Businesses have a major role to play in driving low-carbon growth
Fear is a bad counselor, when it’s about terrorists and refugees. But it’s a welcome guest at the big climate summit that begins today in Paris. Global warming needs to be stopped, we are running running out of time.
The year 2014 went down as the warmest year since records began, but it is likely that 2015 will go beyond that level. Scientists believe that 2016 is ook shaping up as a very hot year and they expect that the one degree margin will become more firmly established in the coming years. “
Yesterday, The UK BBC reported that the world’s temperature has been risen over 1degree Celsius. If this is true, the world would be half way towards 2C, the gateway to dangerous warming.
The year 2015 continues the boundary of one degree away.
“This is the first time we’re set to reach the 1C marker and it’s clear that it is human influence driving our modern climate into uncharted territory,” said Professor Stephen Belcher from the Met Office.
It’s already a historic climate summit. Delegates from 196 countries have to reach an agreement on combating global warming after 2020. The last major climate summit, Copenhagen in 2009, failed because there should be a comprehensive agreement.
More than 150 countries have applied on the eve of the climate conference in Paris in late November with plans and initiatives to stop the global warming.
But all these plans will not be enough to stay below the safe 2 degrees Celsius.
However, they slow down the warm-up, and they make sure that the 2-degree-target in the near future will be feasible without large investments. Read More
In Japan, floods have caused devastations. Torrential rains are associated with former Tropical Storm Etau shifted north after dumping unprecedented rainfall on parts of eastern Japan, last Wednesday and Thursday.
More than a hundred thousand people had to flee because of the high water, which sometimes even carried houses along. Read More
Without engineers the world would be in big trouble
During a water conference in the Netherlands, Wu Jianmin, Vice-chairman of the Chinese Institute for Innovation and Development Strategy, mentioned the Dutch engineering sector as “Small country, big achievements.
And “Without engineers the world would be in big trouble.”
In his speech he forecasted 3 mega trends: Read More
October 11, 2014 – The governor of the Brazilian state of Sao Paulo has asked for emergency clearance to siphon the remaining water out of the main reservoir serving Sao Paulo city, which has almost run dry. After nine months of unprecedented drought, 95% of the water has gone
Florida has severe problems facing high tides issues
Southeast Florida has already begun experiencing the effects of the sea-level rising reality. With, or sometimes even without, severe downpours, sea-level rise — combined with ‘king tides’ — is already causing localized flooding in some areas of Miami-Dade, from Miami-Beach to Sweetwater.
Thames Barrier: A series of river gates, it was built in the 1970s to protect vulnerable London from storm surges. In 1990, the Thames Barrier closed once or twice a year on average, while in 2003 it closed 14 times. It is expected to be useful only for another 50 years because of sea level rise.
Melting ice from the poles could make sea levels rise by up to three feet by the end of the century, scientists claim.
The Thames Barrier would struggle to cope with predicted storm surges, experts say, leaving London at risk of ‘great floods’.
London’s ‘at risk’ list includes the Houses of Parliament, Canary Wharf, 86 railway and Tube stations, 16 hospitals and over half a million homes. And the iconic silver pods of the Thames Barrier can’t keep rising tides at bay forever.
