More than half of the world’s population lives in cities, and that share is growing. Rapid climate change could make many cities unlivable in the coming decades without major investments to adapt.

Hot, humid population centers are becoming epicenters of heat risk as climate changes worsens. It’s calling into question the conventional wisdom that urbanization uniformly reduces poverty.
Cities are among the harshest habitats on Earth. But when planned properly, private gardens can help improve their liveability.
Cities occupy just 3% of the Earth’s surface, yet more than half the world’s population live in urban environments. We need nation-wide plans to keep our cities cool so no one gets left behind.
Parts of Nairobi are already dealing with temperature increases and reduction in humidity. These conditions are associated with increases in mortality, especially in children and the elderly.
Absolute temperatures are expected to rise more slowly in the tropics than in higher latitudes and polar regions, but the combination of heat and rising humidity will make life more challenging.
Poverty and inequality affect the likelihood of your home overheating during heatwaves.
Buildings soak up the sun’s heat, but research shows that white roofs and surfaces can reduce temperatures inside, particularly during heat waves.
Half-a-dozen strategies are effective for cooling urban areas. Used in combination, these strategies can drop the temperature even more.
The world’s fastest-growing cities are in the tropics. They are highly exposed to climate change, especially as urban heat island effects and humidity magnify the impacts of increasing heatwaves.
South Africa needs to develop low-cost housing solutions that are inherently comfortable and environmentally sustainable. Green roofs could be part of these solutions.
Not all of the solutions to the climate and ecological crisis have to be painful.
Taking this step may improve the quality of life for vulnerable people and reduce the amount of air conditioning they use, making their neighborhoods less prone to power outages.
How to move beyond the warm words about tackling urban heat islands to doing something about them.
The urban heat island and summertime blackouts

Today, we're asking why some of the most disadvantaged parts of our cities cop the worst of a heatwave and how you -- yes, you! -- can do your bit to reduce the risk of a summer time blackout.
Climate change is making heat waves more frequent and intense around the world. Cities are hotter than surrounding areas, so urban dwellers – especially minorities and the poor – are at greatest risk.
International problems and local policies are integrally interwoven, whether the nationalists in Washington like it or not.
Our cities are getting hotter. Luckily, as a built environment, we can actually do something about it.
Do you ever feel that the weather is worse on the weekend? Well you might be right!
Recently published research has found that the concentration of poorer people in hotter places is a real problem for cities’ capacity to cope with climate change.
