Climate change impacts are becoming increasingly visible worldwide, including record temperatures, drought, crop losses and wildfires in the United Kingdom, while some political debate remains focused on the cost of implementing climate policies. A BBC Radio 4 discussion examined whether it is already too late to address the crisis.

Guardian columnist Joe Williams said there is still no reason to lose hope and argued that collective action is needed regardless of how much global temperatures rise. Participants also said some climate-related losses may already be irreversible, citing concerns over the survival of birch trees in southern and eastern England.

Williams criticized comments by Conservative MP Nigel Huddleston, saying it conflicts with reality to emphasize the expense of cutting carbon emissions and reaching net zero amid visible climate impacts. He also rejected the argument that the UK should avoid responsibility because it accounts for about 1 percent of global carbon emissions, warning that waiting for countries including China to act would deepen the crisis. The article says political statements should align with the reality of climate change as time to respond rapidly narrows.
