'The real message from the UN Intergovernmental Panel on Climate Change (IPCC) is that capitalism has caused the deadly global warming crisis and is incapable of solving it', John Foster told the Communist Party's political committee on Wednesday evening.

Pointing out that burning oil and gas accounts for 50 per cent of global carbon emissions, he said the big corporations showed no intention of helping reach the Paris Agreement targets to limit global warming to 2°C, let alone 1.5°C.

'Oil is a hugely profitable business for which the major imperialist states and their allies are prepared to go to war', Mr Foster pointed out.

The latest IPCC report insists that failure to impose the 1.5°C limit by 2050 will greatly increase the economic damage, famine, disease and refugee crises caused by rising sea levels, droughts and storms. The thousand-plus scientists who composed or reviewed the report are calling for extraordinary transformations in industry, transportation, energy, land use and construction and the widespread application of carbon capture technology.

'Such an urgent, radical transformation is not possible without large-scale public ownership, investment and planning - which means a revolutionary advance to socialism', Mr Foster argued.

In particular, he insisted that neoliberal policies - including those enshrined in European Union treaties and directives - precluded the action necessary to combat climate change effectively.

The CP international secretary also set the challenge of global warming in a wider context of growing international economic and military conflict and the threat of a new economic and financial crisis.

'In Britain, we can best meet these challenges by stepping up local and national campaigning against austerity, racism, xenophobia and war. This will help create the conditions in which to elect a left-led Labour government free from the pro-big business shackles of the EU Single Market and Customs Union', he proposed.

The CP political committee condemned the imprisonment of three anti-fracking protestors at Preston Crown Court last week as a 'brutal example of how the state reacts when people dare to defend local communities and the environment against the exploiters and polluters'.

Britain's Communists also urged a big turn-out for the Stand Up to Racism national demonstration in London on November 17 against fascism and racism.
