Climate change is possibly one of the most serious environmental threats facing the world today. Global temperature increase is likely to trigger serious consequences for humanity and other life forms.
What is climate change?
In the past 100 years the earth has warmed by 0.7°C. The last decade was the hottest one ever recorded, according to the latest report published by NASA. The result of this is that mountain glaciers are retreating, coral reefs are disappearing, the permafrost in some areas is melting - the list of impacts is long and well publicised. An upward trend in temperatures is visible from Coventry's own local weather station over just the course of the past 30 years.
There is now strong evidence that climate change is happening and that man-made emissions, due to our high use of fossil fuels, are the cause. As this problem is largely man-made, it is our responsibility to act now before it's too late.
What is the greenhouse effect?
Greenhouse gases emitted naturally from trees and animals help make the planet a warm and habitable place. They act like the outside covering of a greenhouse, trapping inside the heat from the sun.
Earth's climate is warming as increasing greenhouse gas emissions trap more heat.
Greenhouse emissions are mainly due to human development activities such as:
- fossil fuel burning (coal, natural gas and petrol) for energy production
- landfills releasing methane
- industrial production processes
- agriculture and livestock
What is global warming?
Most scientists agree global warming is changing the world's climate. Even if greenhouse emissions were significantly reduced immediately, the warming effect would continue for 30 - 50 years as these gases remain in the atmosphere for a long time.
At the current emissions rate, the global temperature could be expected to increase 0.5ºC by 2050. However, while emissions continue to accelerate, scientists predict a 2ºC - 5ºC increase by 2050. Emissions would have to be reduced quickly to lessen this.
What does climate change mean for Coventry?
For Coventry, climate change means warmer, drier summers (more heatwaves and periods of water shortages), milder wetter winters and more frequent and intense storms (increased flooding).
The Coventry City Council has a key role to play in tackling climate change by reducing our carbon footprint from our council own buildings and the services we provide and making sure that we can cope with the impacts of climate change. We also have a community leadership role, in supporting and working in partnership with organisations and individuals to reduce their emissions and adapt to the changing climate. As a city we are working on a new Climate Change Strategy which will be launched in 2020.
