Cities are also one of the most vulnerable parts of the human society to the effects of climate change, [3] and likely one of the most important solutions for reducing the environmental impact of humans. [4] [2] [3] The UN projects that 68% of the world population will live in urban areas by 2050. [5]
With 21% of global methane emissions, cattle are a major driver of global warming. [ 225 ] : 6 When rainforests are cut and the land is converted for grazing, the impact is even higher. In Brazil, producing 1 kg of beef can result in the emission of up to 335 kg CO 2 -eq. [ 226 ] Other livestock, manure management and rice cultivation also emit ...
It is also possible to reduce vulnerability in towns and cities with green garden spaces. These can reduce heat stress and food insecurity for low-income neighbourhoods. [25]: 800 Ecosystem-based adaptation is one way to reduce vulnerability to climate hazards. For instance, mangroves can dampen storm energy. So they can help prevent flooding.
Drivers, processes, and impacts of sinking cities [1]. Sinking cities are urban environments that are in danger of disappearing due to their rapidly changing landscapes.The largest contributors to these cities becoming unlivable are the combined effects of climate change (manifested through sea level rise, intensifying storms, and storm surge), land subsidence, and accelerated urbanization.

As cities update building codes for energy efficiency, they can aim to reduce collisions too. For instance, they can require new constructions and major renovations to use bird-safe glass, which ...
This is a list of climate change initiatives of international, national, regional, and local political initiatives to take action on climate change (global warming). A Climate Action Plan (CAP) is a set of strategies intended to guide efforts for climate change mitigation. [1]
This can be done by using reflective paints or materials where appropriate, or white and light colored paints. Glazing can also be added to windows to reduce the amount of heat that buildings or roofs generate and store. [40] Green roofs also help reduce the urban heat island effect and improve the resilience to urban flooding.
Afforestation can also improve the local climate through increased rainfall and by being a barrier against high winds. The additional trees can also prevent or reduce topsoil erosion (from water and wind), floods and landslides. Finally, additional trees can be a habitat for wildlife, and provide employment and wood products. [2]
