Cities, climate change, and urban emissions: stakeholders, impacts, and strategies

Notes

Stakeholders - people affected by decisions - government -> economic growth + public wellbeing - business -> profit + development - residents - good living conditions (housing, safety, low cost) - environmental groups -> protect nature + reduce pollution # Cities and climate change ## Climate - the average weather of a place over a long time. - weather → what is happening right now. ## Emissions - gases being released, into the air (like CO2) ## Milligation - reducing the causes of climate change ## Adaptation - adjusting to climate change (building shade, flood defences) ## Why cities matter - Cities cause alot of pollution - many people → more energy use, transport and waste. - this increases greenhouse gases ## Sources of emissions in cities ### Main sources: - Cars, buses, planes - burning petrol and diesel - homes (heating & electricity) - waste → transported + buried ## Effect of climate change in cities - heavier rain → flooding - higher temperature → heatwaves - worse air quality → health problem - water shortage - more energy use ## Urban heat island effect Cities are hotter than rural areas ## Why? - building trap heat - roads absorb heat - less heat less coo...
