How climate data can help address the climate challenge

Climate change has already altered the weather we experience and the magnitude of impacts from extreme temperatures and rainfall. These impacts manifest locally and can cause human causalities and damage to infrastructure and natural systems. In future, some further climate change is now inevitable, but the rate and magnitude of change will depend on global greenhouse gas emissions. New data and tools to use the data are available to help plot a path through the climate and weather challenges, enabling organisations at all scales to adapt to the changing conditions.

How climate data can help address the climate challenge

  1. 1. How climate data can help address the climate challenge Professor JasonA. Lowe, OBE
  2. 2. CoP27 Egypt – November 2022 Global carbon emissions and sinks Adaptation Green finance Loss and damage
  3. 3. Global temperatures have risen by ~1.1°C
  4. 4. Global temperatures have risen by ~1.1°C
  5. 5. Extreme weather is causing impacts in Wales (and the rest of the UK) High temperature: July 2022 Flooding Breaking records: • Welsh Maximum temperature record broken: 37.1°C (previously 35.2°C) • Welsh Minimum temperature record broken: 24.5°C (previously 22.2°C) • Overall 8th hottest summer on record for Wales Not just heat • Summer rainfall in Wales was just 54% of the seasonal average. • Pembrokeshire saw a hosepipe ban enforced from 19th August until the 25th October. View of Bute Park and Cardiff Castle after Storm Dennis (Image: Jonathan Lawrance/WalesOnline The Storm Dennis aftermath (Getty Images) Examples from Storm Dennis (Feb 2020) when rivers in south and east Wales reached record levels, after a months rain was recorded in 24 hours. Initial estimates of £175m-£225m worth of damage to homes and businesses (PwC).
  6. 6. Carbon dioxide emissions The amount of future global warming depends on future emissions
  7. 7. The current national pledges of emission reductions when added together do not limit peak global warming below 1.5°C This means society will also need to adapt But we don’t know precisely how much! Current emission pledges
  8. 8. Working together on UK Climate Projections UKCP18 is new set of climate projections produced for UK stakeholders to use to investigate their physical climate risks
  9. 9. a greater chance of warmer, wetter winters and hotter, drier summers
  10. 10. Temperature changes Future UK annual and seasonal changes
  11. 11. Precipitation changes Summer 2061-2070 Winter 2061-2070 Future UK annual and seasonal changes
  12. 12. Periods with 2 consecutive days with temperature above 30°C could become around 16 times more likely The rainfall associated with a 2-year return period increases by 29% by 2070s First national climate scenarios at convection-permitting scale to simulate improved extreme weather UKCP Local (2.2km) projections
  13. 13. Sea-level rise Future UK coastal changes (by 2100 relative to 1981-2000)
  14. 14. The Met Office launched the climate data portal in May 2022 The aim is to help with two challenges: Making climate data, observations and models easier to access Making it easier to bring together climate data with information relevant to users – exposure and vulnerability
  15. 15. Some other Wales specific examples: landslip onto railway lines Future January precipitation projections Overlay onto terrain, then look at gradient Bring in the railway line locations
  16. 16. Some other Wales specific examples: landslip onto railway lines Construct a simple landslide risk index This could be refined further: • Look at soil type • Look at local drainage information • Look at climate extremes
  17. 17. Some other Wales specific examples: overheating in care homes
  18. 18. What are people saying about the climate portal? 'it becomes possible to service a much larger number of customers, and to provide them with a better service though saving millions of minutes of time.’ Carbon accounting business. 'The really big benefit is that we can quite quickly take a look spatially at the data to get an idea of if this is actually going to be useful for our purposes’. A national nature based charity. ‘We hope to use this information to better understand what extreme climate we can expect in certain places in the future (e.g. extreme rainfall events) and so we can take early adaptation action in these specific places to mitigate potential impacts - evidence based land management decision making! A Government agency in Scotland ‘If I could say this is going to happen and it is backed by science then I’d have a stronger case... get the powers that be to take things seriously’ - Cardiff City Council
  19. 19. Optimise the energy from renewable sources Meet regulatory reporting requirements Formulate climate-aware land management plans How can you use the data? Developing resilient transportation networks Understanding the health implications of climate change Adapting cities, urban spaces and housing
