What is climate change?
There is clear scientific evidence to show the climate is changing because of emissions of greenhouse gases resulting from human activity.
The bulk of emissions derive from demand for energy (heat, power, transport). The largest contributor is carbon dioxide (CO2), emitted when fossil fuels are burnt to meet those demands. There are also other emissions attached to industrial processes and agriculture.
The basics of the Green House effect are addressed by many including the Royal Society which has a one minute video. Our greenhouse gas emissions have already created a warmer planet; we are already experiencing the impacts of a changing climate, including increased flooding, rising sea levels and extreme weather events.
Solutions exist, by improving our energy efficiency, switching to renewable energy to power and heat our buildings and transport and restoring carbon sinks; we can create a safer climate, save lives, livelihoods and improve wellbeing.
Why is this important?
- Climate Change is an existential threat, it relates to the existence of life. We are already experiencing dangerous climate change. It requires bold action to address.
- The World Wildlife Fund (WWF) has created some infographics on the impacts of Climate Change. This information highlights the difference between 1.5 degrees and 2 degrees warming, summarising information from the IPCCs SR1.5. Some low-lying islands are already being evacuated due to sea-level rise, predicted climate change will increase flooding, heatwaves, sea level rise and more. Our actions now can save lives and livelihoods.
