Every year countries pledge to cut their greenhouse gas emissions to curb the impacts of climate change. But still temperatures keep rising. Last month scientists announced that the average rise in global temperatures would likely pass the 1.5C threshold in the next five years. With temperatures rising we will see more heatwaves, wildfires and floods. From 5 to 15 June countries’ leaders are meeting at the Bonn climate conference to discuss, among other things, local communities and indigenous peoples, pre-2020 ambition and implementation, science, and oceans. They will review their pledges as they look ahead to November’s COP28. Even a small increase in average temperatures makes a big difference as the whole distribution of daily temperatures shifts to warmer levels, making hotter days more likely and more extreme. See
