Climate change will cause waves of migration into Britain that will make current levels seem like 'nothing', former head of MI5 warns

Climate change will trigger migration to the UK that will make current, conflict-driven levels seem like ‘nothing’, the former head of MI5 has warned.

This will be the result of migrants fleeing their homes as they become ‘uninhabitable’ from extreme weather.

Baroness Eliza Manningham-Buller, who was director general of the intelligence agency from 2002 to 2007, spoke at a National Farmers’ Union lecture on Monday.

She discussed how climate change directly threatens food security in Britain, and the potential migrant influx should be a ‘strong reason’ to address it.

She said: ‘The migration we have seen so far as a result of a conflict in some cases or economic migration will be as nothing compared to the migration which the northern countries in the hemisphere are going to see as people move away from areas that are uninhabitable.

‘And that is a very strong reason to address the climate issue. Because if we don’t address it fully and properly, this is going to happen.’

A report from the World Bank published last year predicted that 216 million people could be forced to migrate to other parts of their country by 2050 due to rising sea levels, water scarcity and declining crop productivity.

Worldwide, farmers are growing 20 percent less food than they would be if environmental conditions were the same as they were in the 1960s.

Yields of potatoes, onions, carrots and lettuce suffered due to this year’s record-breaking heat

While the government plans for the country to reach net-zero carbon emissions by 2050, Baroness Manningham-Buller is sceptical this will be achieved.

She said at the 2022 Henry Plumb Memorial Lecture that the world is becoming ‘so polarised’ that we won’t be able to come together as necessary to meet the targets.

In 2014, scientists warned how climate change could result in conflicts and wars breaking out as growing populations fight over dwindling resources and food prices fluctuate.

During her talk, Baroness Manningham-Buller said that the war in Ukraine demonstrates the importance of insulating Britain from shocks to the global food system.

Since Russia invaded Ukraine in February, food prices have been escalating as supplies are squeezed, including grain and fertilisers.

By the end of last month, nearly all bread and pasta items had risen in inflation

Baroness Manningham-Buller said: ‘I believe that food is part of our critical national security, including the essential workers that grow it and harvest it, the farmers that produce our crops, meat, vegetables, fruit and even wine.

‘British farmers are under immense pressure. The doubling of fertiliser prices, soaring energy costs, shortages of seasonal workers and apprehension about trade deals are all impacting the farmers that produce our food and we urgently need policy to address this.

‘Unless we pay serious and thorough attention to our food security, we risk being increasingly subject to global shocks.

‘We need to acknowledge that we should produce as much of our own food as possible and to be able to export what we can, both for growth in the UK economy and to help feed the world.’

NFU President Minette Batters added: ‘As British farmers we produce both climate-friendly food and renewable energy and we want to deliver more.

‘For this to happen, we need our government to honour the commitments made by Prime Minister Rishi Sunak to set a target for our nation’s food security, with a statutory duty to report on domestic food levels.’
