  • temperatures were among the highest in the UK today here in Kew Gardens, a scorching 37.7 degrees.

  • So those who braved the sunshine came prepared, and climate scientists are now confident that he waves are more likely and more extreme because of climate change.

  • The fact that we've seen these temperature rises, the baseline temperature has increased by about one degree globally since pre industrial times, and it's that level that just means in normal conditions we would see heatwave conditions and temperatures around kind of just above average.

  • But you have the extra layer of heat on.

  • That's when we start to break those records and globally over the last century.

  • The trend is clear.

  • It has been heating up.

  • The last four years were the warmest ever recorded for the future.

  • The temperature increased depends on global carbon emissions.

  • Current targets that governments have signed up to to limit those emissions will see a rise of about 3.3 degrees by 2100 under the Paris climate agreement.

  • That's the more ambitious deal signed up to by almost 200 countries in 2016.

  • The aim is to keep that below 1.5 degrees.

  • Today of all days, we've come to the hottest glasshouse in Kew Gardens.

  • But this is where all the desert adapted plants live, and even for these plants, they've opened all of the windows to try and get some ventilation in here because, according to my thermometer is now more than 39 degrees in here, and these plants are adapted to the hottest, driest conditions on Earth.

  • It's those adaptations that scientists here of studying in order to work out how we might grow more drought resistant plants in the future.

  • While the collections here look exotic, they contain plants that could eventually become familiar food crops.

  • Days like today tell us that if we carry on doing exactly what we've done in the past, then that that's not going to work.

  • So we're going to have to adapt what we do and potentially adapt the crops we grow.

  • And so we need to be exploring.

  • We need to be researching room need to understanding our options so that we can change as as climate begins to bite with the gardens baking in the sun today, the preparation continues for a warmer, more uncertain climate in the future a scorching 37.7 degrees.

  • So those he braved, the sunshine came prepared.

  • And climate scientists are now confident that heat waves are more likely and more extreme because of climate change on globally over the last century.

  • The trend is clear.

  • It has been heating up.

  • It's those adaptations that scientists here studying in order to work out how we might grow more drought resistant plants in the future.

  • With the gardens baking in the sun today, the preparation continues for a warmer, more uncertain climate in the future.
