Climate Proof Cities

climate proof cities

A quarter of the planet will experience severe water shortages one month per year by 2030.

Cities ​are ​highly ​vulnerable to ​climatic risks. ​Think of heatwaves, water scarcity and extreme rainfall.

What can cities do to become resistant climate proof? Let’s give an overview. Read More

Threat to the climate? – Our brains!

Threat to the climate? - Our brains!

We install LED lights in our house and then we step with a clear conscience in the aircraft for a holiday in Thailand.

More rain, less snow on Arctic

More rain, less snow on Arctic

According to climate researchers, more rain than snow will fall in the Arctic. Moreover, oceans are getting hotter, and they’re also losing oxygen

According to climate researchers in the Netherlands, at the end of this century more rain than snow will fall in the Arctic. It was already known that, due to global warming, up to 60% more precipitation would fall in the Arctic.

The researchers now argue that it mainly involves rain, while scientists always presuppose the precipitation would be snow. Read More

Cape Town is running out of water

Cape Town is running out of water

Helicopters release water bombs to stop the wildfire but they are afraid to use salty sea water because that damages the vegetation.

Cape Town, South Africa is running out of water. The city has been struck by severe drought and there is enough water for just 100 days.

Just like Sao Paulo in 2015, citizens are asked to conserve and reduce their water supply. Kevin Winter, lecturer at the University of Cape Town Environmental and Geographical Sciences: 

“We can’t see any rain on the horizon. And right now, in terms of dam storage levels, we’re probably approaching the ‘100 days left of storage.

Reduce risks storming water

Flood, industry, risk management, climate change, stormwater, hurricanes

The US President has declared a federal disaster for the storms and floods that struck 8 counties of Iowa during late August 2016.

Storming Water costs lives and a lot of money. Last winter, more than 15,000 homes and businesses in just eight council areas in the USA were flooded, a survey has revealed.

In October, the US President has declared a federal disaster for storming water and floods that struck 8 countries during late August 2016

The research for the Local Government Association found that councils were still helping flood-hit homes recover.

Councils are encouraging people to check if they are at risk of flooding this year, to sign up to flood warnings and make sure their homes are prepared. Read More

20% of the world’s population will migrate by sea-level rise

Sea-level rising: populations at risk

Even if global warming is capped at 2C, 20% of the world’s population will have to migrate away from coasts swamped by rising oceans. 

Even if global warming is capped at governments’ target of 2C, 20% of the world’s population will be to migrate to higher area’s because of rising sea levels.

Countries like the Netherlands and Bangladesh and cities including New York, London, Rio de Janeiro, Cairo, Calcutta, Jakarta and Shanghai would all be submerged because of melting polar ice caps and sea-level rise. Read More

SF needs to speed up to climate change

SF needs to speed up to climate change

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

Porous concrete on roads means: less traffic noise and the end of splashing water and aquaplaning

In Europe we know this permeable or porous concrete saves may lives during the year. Why? Because the road stays dry, even with stormy weather. And we will face an increasing lot of storms the upcoming years.

A lot of countries don’t invest in permeable concrete. But maybe this system will change their minds.

Porous concrete on roads means: less traffic noise and the end of splashing water and aquaplaning

The average motorist appreciates the comfort of the porous coating. But there are also disadvantages:

  • higher costs for construction
  • less skid resistance of the road surface immediately after installation
  • reconcilable problems in combating snow and ice

From 1950 to 1980 the number of people living in favelas in Rio de Janeiro alone increased from about 170,000 to more than 600,000, and by the early 21st century it was estimated that there were as many as 1,000 favelas there.

Given the rate of change, our world will be a very different place by 2040. More and more people are moving to cities.

How will billions of city-dwellers access what they need without putting intolerable strains on the planet?

How can we plan now for more sustainable ways of life in a radically different world?
