More threats, more desperate refugees as climate warms: US

Washington DC: The Earth's warming and resulting natural disasters are creating a more dangerous world of desperate leaders and peoples, the Biden administration said Thursday in the federal government's starkest assessments yet of security and migration challenges facing the United States as the climate worsens.

The Defense Department for years has called climate change a threat to U.S. national security.

But Thursday's reports by the departments of Defense and Homeland Security, National Security Council and Director of National Intelligence provide one of the government's deepest looks yet at the vast rippling effects on the world's stability and resulting heightened threats to U.S. security, as well as its impact on migration.

They include the first assessment by intelligence agencies on the impact of climate change, identifying 11 countries of greatest concern from Haiti to Afghanistan.

Another report, the first by the government focusing at length on climate and migration, recommends a number of steps, including monitoring the flows of people forced to leave their homes because of natural disasters, and working with Congress on a groundbreaking plan that would add droughts, floods and wildfires and other climate-related reasons to be considered in granting refugee status.

The climate migration assessments urge the creation of a task force to coordinate U.S. management of climate change and migration across government, from climate scientists to aid and security officials.

Each year, storms, the failure of seasonal rains and other sudden natural disasters force an average of 21.5 million people from their homes around the world, the U.N. High Commissioner for Refugees says. Worsening climate from the burning of coal and gas already is intensifying a range of disasters, from wildfires overrunning towns in California, rising seas overtaking island nations and drought-aggravated conflict in some parts of the world.

Policy and programming efforts made today and in coming years will impact estimates of people moving due to climate-related factors, said the report, one of dozens of climate change assessments President Joe Biden ordered from federal agencies.

Tens of millions of people, however, are likely to be displaced over the next two to three decades due in large measure to climate change impacts.

The Biden administration is eager to show itself confronting the impacts of climate change ahead of a crucial U.N. climate conference in Glasgow, Scotland, that starts late this month. That's especially so as Biden struggles to get lawmakers to agree to multibillion-dollar measures to slow climate change, a key part of his domestic agenda.

As part of its push Thursday, the administration released the first-ever national intelligence estimate on climate change, a document intended to signal the importance placed on the issue. National intelligence estimates are benchmark documents created by U.S. intelligence agencies that are intended to inform decision-making and analysis across the government. Notably, U.S. intelligence agencies concluded it was probably already too late to keep the warming of the planet at or below the level laid out in the 2015 U.N. Paris climate accord.
