UN Appeals for 'Unprecedented' Steps to Avert Worst Effects of Global Warming

UN Appeals for 'Unprecedented' Steps to Avert Worst Effects of Global Warming

If 1.5 degrees of warming does occur, Southeast Asian countries like Indonesia, the Philippines, and Vietnam, including countries like Japan, China, Egypt, and the USA will experience increased flooding by 2040. Some HFCs have a global warming potential more than 11,000 times that of CO2.

There is a new report out from the Intergovernmental Panel on Climate Change (IPCC). The IPCC believes that this is achievable.

The United Nations Intergovernmental Panel on Climate Change says there will be irreversible changes and the entire loss of some ecosystems if the world doesn't take immediate and intensive action to cut greenhouse gas emissions far more than is occurring now.

Yet, to limit global warming to below 1.5°C, drastic action is needed in land, energy, industry, buildings, transport and city policy, the IPCC said.

The goal is to cap global warming at 1.5 Celsius (2.7 Fahrenheit) above pre-industrial levels, which the group said may prove almost impossible unless swift action is taken.

"Limiting global temperature increases to 1.5°C means significantly decreased levels of food insecurity, water shortages, destruction of infrastructure, and displacement from sea-level rise and other impacts".

The recent floods in Kerala displaced more than 700,000 people and caused close of 500 deaths.

If the IPCC report is anything to go by, India would be worst affected. By the year 2030, global human-caused emissions of Carbon dioxide would need to fall by roughly 45 percent relative to 2010 levels.

That was the Paris agreement's most ambitious target (a 2-degree C rise was established as a more practical goal).

"If we're serious about keeping global warming well below 2 degrees Celsius and striving for no more than 1.5 degrees, we can not afford further delay".


Limiting warming to 1.5°C is possible within the laws of chemistry and physics but doing so would require unprecedented changes, Co-Chair of IPCC Working Group III Jim Skea said.

They're calling for "rapid, far-reaching and unprecedented changes" across society to prevent world temperatures from rising by two degrees Celsius.

Temperatures are now about 1° C higher than preindustrial levels.

However, it does make clear the consequences of warming above that level: more heat waves, more severe rain and snow events, higher sea levels, damage to agriculture and displacement of millions of people.

The Arctic is likely to be ice-free in summer around once a century at 1.5C but at least once a decade if warming climbs to 2C.

This means that weaning off coal and fossil fuels could not only help reduce carbon emissions and help limit the global temperature rise but also result in economic benefits. "We hope that this report will encourage policymakers to embrace all low-carbon energy sources".

"We are still going to see many challenges at 1.5°C".

"That's what the scientists predicted, and it's what we're seeing play out now right in front of our eyes. We have a narrow window now to act if we are to protect God's creation for generations to come - as individuals, communities and as a global family".

The corresponding October 8, 2018 IPCC "Summary for Policymakers of IPCC Special Report on Global Warming of 1.5°C approved by governments" press release lays out report findings, perhaps the most important of which is: "Limiting global warming to 1.5°C would require rapid, far-reaching and unprecedented changes in all aspects of society, the IPCC said in a new assessment".

The impact of 1.5 degrees Celsius warming is greater than what was anticipated earlier while the impacts at two degrees Celsius are "catastrophic" for the poor and for developing nations such as India, the Centre for Science and Environment (CSE) said.
