What is the climate and ecological emergency?

In 2019 H&F Council declared a climate and ecological emergency. Find out more about what this is below and explore local impacts and risks.

  • What is the climate emergency?

    Climate change is being caused by human activity emitting greenhouse gases.

    The main causes of climate change are:

    • burning fossil fuels (like petrol, diesel and gas) for energy
    • deforestation
    • farming
    • the manufacture of cement, metals and chemicals


    Over the past 100 years greenhouse gases in the atmosphere have increased by 50%. This causes the ‘greenhouse effect’ which is heating the atmosphere, endangering people and the planet. 

    The world has already warmed by 1°C since records began.

    The UN reports that we must take radical action by 2030 to keep climate change within safe levels. Beyond this, catastrophic and irreversible change is expected.

    Yet as of 2019 the amount of greenhouse gases we are emitting continues to rise. The action planned in the UK to date is not enough to meet its climate commitments.

    That's why in 2019, H&F Council declared a climate emergency. We set an ambitious target to reach net zero carbon emissions by 2030 for our borough.

    These ‘warming stripe’ graphics are visual representations of the global average temperatures over the past 100+ years. Each vertical stripe represents one year. Blue shows a cooler average temperature. Pink and red show a warmer average temperature.

    This image shows that temperatures have increased rapidly over the past 10-15 years. The ten hottest years ever recorded in the UK all occurred since 2002.

  • What is the ecological emergency?

    Biodiversity is another world for "life on earth". The natural world provides food, health, wellbeing and solutions to climate change. You can think of biodiversity as the foundation for our entire economy. 

    Yet world-leading scientists worry that we are on the cusp of a sixth global mass extinction.  

    • 1 in 4 species are at risk of extinction
    • Species populations have decreased 60% since the mid-20th century

    We have known about this problem for some time and there have been previous attempts to conserve wildlife and restore nature. Yet even with these efforts we have not reached these global targets.

    As humans, we are responsible for this drastic decline in biodiversity. There are 5 main causes. These causes lie close to home and are explained below. 

    1. Habitat loss and degradation - Losing gardens and hedgerows is causing a swift decline in many iconic British species. We have lost 97% of hedgehogs in the UK since the 1960s.  

    2. Pollution - The Thames has some of the highest levels of microplastic pollution in the world.  

    3. Exploitation - Overexploitation of native oysters has led to a 95% decline in their population size. 

    4. Invasive species and disease - You may have seen parakeets in London. These were introduced by people and have a detrimental impact on many of our native birds.  

    5. Climate change - 48% of UK moth populations have declined as a result of changing weather patterns.  

    H&F Council are one of the only councils to declare an ecological emergency. It is not too late to restore biodiversity if we act now. 

  • Local impacts

    Investment in climate resilience today will help avoid costs from an extreme and changing climate.

    Flooding  

    Increasing rainfall levels are being recorded almost every year and risk local flooding. Flooding poses grave risks to life, homes, infrastructure, and mental health. Most of our borough is at risk from surface water flooding as heavy downpours become more likely.  

    Extreme heat   

    Hammersmith & Fulham is vulnerable to extreme heat. Our density of building creates an ‘urban heat island’ that can be to 10°C hotter than outside London. We can expect heatwaves like that of August 2020 every other year by mid-century.  

    During the heatwave in 2020 Hammersmith Bridge was closed to all traffic. The bridge fractures were aggravated by the extreme heat. 

    Heat-related deaths in the UK are projected to rise five times to over 12,000 per year by 2080. Vulnerable groups, like the very young and very old, are most at risk.   

    Drought 

    London is at risk from drought, with a shortfall of water supply projected to reach 400m litres per day by 2040. Droughts impact health, business, infrastructure and amenities; the cost to London of extreme drought is estimated at over £330m per day.
