My Lords, it is true that the UK Government have been on the front foot on climate change and have commendably taken a lead internationally on the issue since the Paris agreement, but they still need reminding that the least developed countries are still suffering the worst effects and some—not just island states—face imminent threats from floods, drought and other disasters.

In 2018, we had some of the worst emergencies ever. We had some experience of it: the UK had unusual extremes of weather last year, and California’s autumn fires were catastrophic. But in the southern hemisphere, Kerala had its worst floods for more than 80 years last August, with more than 2.5 times the normal rainfall from the monsoon. More than 500 died and more than 1 million were forced from their homes, with 10,000 houses destroyed and roads damaged at a cost estimated at $3.5 billion. The warming of the atmosphere from greenhouse gas emissions is an obvious cause of such dramatic turns in the weather, and India is one of the countries that will suffer most.

South Africa, on the other hand, experienced three consecutive years of low rainfall, and Cape Town faced its worst drought ever a year ago. Taps ran dry in the city and residents were severely restricted. Again, scientists found that climate change made the drought three times more likely.

Argentina also ended its worst drought in 50 years last April, but the economic consequences for farmers were considerable. The soybean and corn harvests were down by 31% and 21%, and lost production cost Argentina $6 billion, plunging the country into recession. I am grateful to Christian Aid for providing those figures.

Very few people in Parliament or among the general public doubt that these major emergencies were linked to climate change, as has been reaffirmed at successive conferences. The Katowice conference in Poland made good progress last December towards implementing the Paris rulebook. In recent Westminster debates, the Government have sounded upbeat. One Minister has since even admitted that the UK will need to legislate for a net zero emissions target “at an appropriate point in the future”.

But the situation is urgent. According to Christian Aid, overall global emissions must reach zero—meaning that human activities absorb as much greenhouse gas as they release—by the middle of the century if the world is to limit warming to 1.5 degrees centigrade, the target set in the 2015 Paris agreement. Next year, there will be an interim meeting in Chile, but the real decisions will have to be made very soon in Europe.
