Ed Miliband: climate crisis puts national security of all countries at risk

Ed Miliband, the United Kingdom’s foreign secretary, is set to address world leaders at the Cop31 UN climate summit in Turkey, emphasizing that the climate crisis represents a critical national security concern for countries globally. Miliband plans to argue that environmental degradation directly threatens national security through cascading impacts including food shortages, infrastructure damage, involuntary migration, and potential conflict between nations.

The foreign secretary’s remarks come as part of the fortnight-long Cop31 talks, which began earlier in the week. The leaders’ summit segment is scheduled for Wednesday and Thursday in Antalya, with various world officials in attendance. Several major world leaders have opted not to attend, including representatives from China, India, France, and Germany, though the European Commission president and leaders from Australia, Brazil, and Ethiopia are expected to participate.

Miliband will highlight the consequences of three decades of insufficient carbon emission reductions. He will note that the planet has already exceeded the critical 1.5 degrees Celsius warming threshold above pre-industrial levels for two consecutive years, with temperatures unlikely to decline significantly in the near term. This overshoot, according to Miliband, necessitates stronger policies to prevent accelerated heating and to develop strategies for returning global temperatures to safer levels over coming decades.

The foreign secretary will also address the economic destabilization caused by fossil fuel price volatility. Recent energy price shocks, including oil price increases following geopolitical conflicts, have contributed to inflation and prompted central bank interest rate increases worldwide. Miliband contends that such fossil fuel-related economic disruptions will persist as a persistent threat requiring urgent transition to clean energy sources.

Miliband’s government is simultaneously facing domestic criticism from climate advocates who contend that recent policy decisions undermine the nation’s net zero emissions target for 2050. These decisions include modifications to electric vehicle manufacturing mandates and approvals for new fossil fuel extraction projects in UK waters.
