The reality is that the future of cities before the climate change is a headache for more of an urban planner who, being aware of the possible consequences pose challenges that go beyond the art of project architecture or cities .
More skeptics or less, a raise approach a couple of degrees in global temperature conditions a totally new urban landscape that must be analyzed and taken into account.
For those who the weather theme come a long way, two articles that we believe are of interest and they confirm a reality that many ignore; from the this portal with five graphs that demonstrate that the change climate change is here and this past Monday, the agency British meteorological Met Office announced that this year, the global average temperature at the surface of the Earth will be one degree Celsius higher than levels pre-industrial.

As a summary, we believe that the following table expresses clearly some possible weather effects both in homes and in the architecture of cities .
Foresee what will happen with a rise of 2 degrees of temperature in our city obviously it is difficult to clarify although from Proceedings of the National Academy of Sciences (PNAS) following the publication of a new study called “Mapping Choices. Carbon climate and rising seas our global legacy« shed some light on a more than important topic, the relationship between the rise in global temperature of the earth and the elevation of the sea level according to territories, cities or a country .
The report published by PNAS, in addition to its tool, analyzes the projections of sea level rise – on the ground – in function of greenhouse gas emissions greenhouse released into the atmosphere.
A scenario that examines what would happen if successful stop climate change by not exceeding more than two degrees. In addition, another hypothesis is considered if the four degrees.
In the following interactive map we can search and geolocate a city to see the changes of sea level according to the increase in temperature in two degrees or four degrees. The map can be accessed from HERE to see what is shown in the image next:
Roughly speaking. It is established that there are 20 countries with direct affectation and importance according to the maps established before the rise of the sea level in 4 ° C in global warming compared to 2°C, in relation to the percentage (%) of population.
How can you check on the graph, about 3% of the Spanish population would be affected before a rise in sea level due to the effects of two degrees more in global temperature .
Science fiction or not so much, the following images interactive urban landscapes made by Climate Central show an example of a “catastrophic” scenario in cities such as; London, Shanghai, Sydney or New York, how far sea level can reach if global measures are not taken to reduce emissions that cause climate change. (We can move the central cursor of the images to see a better perspective)
“It is not that sea level rise it will flood your house in your lifetime. It's about our legacy and threat to world heritage and world cities that will unfold over time, probably many centuries. But it will be defined by the decisions we make now” emphasized scientist Ben Strauss Author of the previous images.
In return, let's remember the article on building resilience in cities from a perspective aimed at reducing natural disasters in cities and their urbanism. A concept that requires attention where resilient cities are a weapon to survive before the climatic changes.
