Evidence shows that our climate is already changing. Some changes are now inevitable and more extreme changes will become unavoidable unless we drastically reduce our carbon emissions. Climate projections show that London will experience warmer, wetter winters and hotter, drier summers.
As well as the gradual change in overall climate, we expect to see more frequent and intense episodes of extreme weather, meaning that we will need to consider adapting our buildings, communities and lifestyles to prepare for more frequent:
Dealing with the consequences of climate change is known as ‘adaptation’. This includes actions such as improving resilience to flooding, modifying our buildings so they remain cool during the hotter summers, and reducing our water use to tackle drought.
Adapting to climate change is a process. It needs to be built into our normal planning and risk management procedures, whether in business, government or service design.
Considering it in parallel with climate change mitigation will ensure that the balance is right and avoid making costly mistakes. An integrated approach to climate change
ensures that sustainable adaptation decisions can be made at the right time to maximise the benefits and minimise costs to services and people. Proactive adaptation is much cheaper than retrospective actions and disaster recovery.
We must ensure we are ready for our changing climate today and tomorrow.
Extreme weather isn’t just something that we need to build resilience to for the future: it’s something that affects us already. If we look back over just the last 13 years we can see extreme weather incidents affected us almost every year:
|2014||Winter storms, flooding|
|2013||Snow and ice, heatwave, strong winds, winter storms|
|2011||Unusually warm spring, Unusually warm autumn|
|2010||Snow and ice, flooding|
|2009||Snow and ice, flooding|
|2008||Snow and ice, flooding|
|2007||Snow and ice, flooding|

The impacts of extreme weather events are far-reaching, and they are felt particularly acutely in multicultural cities such as London, where many of our inhabitants originate from other parts of the world. LCCP recognises that global extreme weather events can impact on the wellbeing of Londoners and their families in a number of ways.
Extreme weather events and changes in climate around the world also have an impact on London’s financial wellbeing through impacts to supply chains and stock prices.
