Scientists say the human race will have to adapt to rising CO2 levels in order to prevent the world from being “unequally divided” into “carbon-free” and “carbon free” countries.

The World Bank and other international bodies have warned that a warmer world would be “inevitable” by the end of the century, with potentially catastrophic consequences for global agriculture and food production.

But scientists are concerned about the potential impact on our food security, which has been threatened by climate change.

They warn that a rise in CO2 concentrations would mean that “farming and food-processing systems will be affected”.

They also warn that the “polarisation” of the planet could be even more severe than previously thought, with parts of the world potentially facing severe weather, floods, droughts and other “climate-related threats”.

The researchers, from the World Bank, and others, published a paper in Nature on Tuesday that says: “Climate change poses an existential threat to global agriculture, and we need to be on the front lines of tackling it.”

The scientists warn that warming temperatures will mean: The risk of increased crop losses; A loss of the ability to grow crops such as wheat and rice, the major staple crops for the developing world, because of the heat.

They say: “In addition to food security concerns, CO2 increases are likely to have impacts on other key aspects of food security.”

The researchers also warn of a “massive and persistent” reduction in crop yields that could affect people’s livelihoods and the sustainability of farming.

The researchers say: The warming of the climate and the growing frequency of droughms could cause a huge shift in food production patterns.

This could make it harder to produce enough food to meet global demands for both food and energy, as well as the social and political impacts of food shortages.

They also say the increased risk of crop loss could cause “extreme disruptions” to global trade.

The scientists say that “even without mitigation measures, the CO2 increase will have an enormous impact on food security”.

They warn: “This is a global challenge and a global security challenge.

The world has to make a strong decision now.”

“If we do not act, we risk the world being unequally divided into carbon-free and carbon free countries,” they said.

“In other words, it is very likely that the world will be in the carbon-neutral zone for the foreseeable future.”

“We do not yet know how the climate will respond to a CO2 rise of around 3-4% [and] the risks are not yet fully quantified,” they added.

“However, if we do have a situation of increasing CO2, it could be a very significant threat to the survival of the human population.”

The paper’s co-author, Joost van den Berghe, a senior researcher at the World Resources Institute, said: “The ‘peregrine crisis’ is already here.

We can’t wait for another ‘peretrain’ to come and we’re already seeing that with the rapid spread of CO 2 .”

The researchers wrote: “We need to get the climate under control as quickly as possible and avoid further CO2 amplification.

In addition to the human welfare, the planet’s resources and food security are at stake.”

They added: “A large CO2 spike would mean significant impacts on food production and consumption, economic and political crises in countries, and the possibility of global famines.”

The World Resources Council said the researchers had a “deeply nuanced understanding” of climate science, adding: “They provide the most rigorous, in-depth and detailed analysis to date of the global CO2 cycle.”

It said the scientists had already found “significantly increased” CO2 in the atmosphere, but the researchers “dramatically underestimate” the amount of CO3 in the Earth’s atmosphere.

“These estimates are based on an assumption that CO2 remains at levels in the past, but this assumption has significant uncertainties, particularly in the case of future CO2,” it added.

‘Climate change is irreversible’ The World Wildlife Fund (WWF) warned that the risks of rising atmospheric CO2 were already clear.

Climate scientists have already predicted that the climate is becoming more extreme, and they are also warning that there is an inevitable link between rising CO² and warmer weather.
