Scientists issue most dire warning yet on climate change


'While it's technically possible, it's extremely improbable, absent a real sea change in the way we evaluate risk.

The 48th IPCC session in South Korea's western port city of Incheon brought together about 570 representatives from 135 countries and global organisations, Xinhua news agency reported.

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".

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

Slowing the rise to 1.5°C above pre-industrial levels would involve "rapid, far-reaching and unprecedented changes in all aspects of society", the report warns with socioeconomically disadvantaged areas likely to be disproportionately impacted.

The report, which was authored by 91 scientists and review editors from 40 countries, cites over 6,000 scientific references, and represents the work of thousands of experts and government employees.

'The faster governments phase out coal, embrace the renewable energy revolution and move to protect communities at risk, the more lives and livelihoods will be spared'.

The comments were his first regarding the report released Monday by the United Nations.

'Right now it's hard, but not impossible, to contain climate chaos, but the window of opportunity will close for good the longer we delay'.

Some environmental damage (like dead coral reefs) could be irreversible if the world heats up by more than 2 degrees Celsius.

"That is where I think the politicians need to really start taking notice in Australia".

Dr Stephen Cornelius, chief adviser on climate change at WWF, said the world was already seeing the loss of natural habitats and species, shrinking ice caps and rising sea levels. "These are impossible targets but will contribute to future discussions". WWF calls on leaders to accelerate climate action immediately'.

One of them, who didn't want to be identified, told The Hindu that the report gave a more comprehensive assessment of the differences in a 1.5C world and 2C world and quantified the carbon dioxide that would need to be removed from the atmosphere to achieve this. It calls for urgent action to get climate change under control and warns of dire consequences if we fail.

Researchers found that "human caused" C02 emissions need to be cut by almost half of 2010 levels by the 2030 to starve off the worts effects of climate change.

The landmark Paris Agreement adopted in December 2015 by 195 nations at the 21st Conference of the Parties to the UN Framework Convention on Climate Change (UNFCCC) included the aim of strengthening the global response to the threat of climate change by "holding the increase in the global average temperature to well below 2°C above preindustrial levels and pursuing efforts to limit the temperature increase to 1.5°C above pre-industrial levels".

The Nobel Prize-winning Intergovernmental Panel on Climate Change issued its gloomy report at a meeting in Incheon, South Korea.

While it is not said that it is impossible to limit global warming to 1.5℃, however, scientists have said that attaining it would be a very hard task.

- If the pace of warming continues, the temperature would reach 1.5C around 2040.

Scientists and climate researchers have long doubted that the 1.5-degree C goal was practical or economically feasible. We need to redouble our efforts to increase our level of ambition to lowering our greenhouse gas emissions in the next round of our national commitments which are due by 2020.
