United Nations report warns of possible climate disaster by 2040

United Nations report warns of possible climate disaster by 2040

"One of the major issues is that there would be 420 million people less suffering because of climate change if we would be able to limit the warming to 1.5-degree level. Even the scientists were surprised to see how much science was already there, and how much they could really differentiate and how great are the benefits of limiting global warming at 1.5 compared to 2", IPCC vice chairwoman Thelma Krug said in an interview. Temperatures would be 1.5C higher between 2030 and 2052 if the world continued at its current pace, it warned.

The new report sets those levels much lower and measures devastating climate change effects much sooner.

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 report shows that we only have the slimmest of opportunities remaining to avoid unthinkable damage to the climate system that supports life as we know it", Amjad Abdulla, an IPCC board member and chief negotiator for the alliance of small island states, told Reuters news agency. Limiting global warming to less than 2ºC will hopefully allow ecosystems and animals to adapt to the gradually rising temperatures.

"Even at a little over 1.0°C warming, India is being battered by the worst climate extremes - it is clear that the situation at 1.5°C is going to worsen".

The IPCC warns, however, there is a stark difference between 1.5 and even 2 degrees Celsius of warming. Coral reefs would decline by 70-90 percent with global warming of 1.5 °C, whereas virtually all ( 99 percent) would be lost with 2 °C.

"It's a line in the sand and what it says to our species is that this is the moment and we must act now", Debra Roberts, cochair of a working group on the impacts of climate change, tells The Guardian.

This target was long considered the threshold for the most unsafe effects of climate change, including the mass destruction of coral reefs, widespread food shortages, destructive wildfires and coastal flooding.

"The government will take into account. the recommendations of the [council] and. the IPCC's special report to draw up Hong Kong's long-term decarbonisation strategy up to 2050 by the end of 2019 or early 2020", the spokesman said.

However, keeping global warming below this level will require "annual average investment needs in the energy system of around $2.4 trillion (around €20.8 trillion)" between 2016 and 2035, according to the report.

Countries will need to bring down their greenhouse gas to about half of 2010 levels by 2030 and to net zero by about 2050. "The latter would be used as part of a now nonexistent program to get power from trees or plants and then bury the resulting carbon dioxide emissions in the ground, leading to a net subtraction of the gas from the air - bioenergy with carbon capture and storage, or BECCS".

"Limiting global warming to 1.5ºC would require rapid, far-reaching and unprecedented changes in all aspects of society", an IPCC press release reads. "'It's a good reminder that no one experiences the global average temperature'".

The effectiveness of such techniques are unproven at large scale and some may carry significant risks for sustainable development, the report notes.

Still, Cleetus says that we have most of the technology we need to make the change. According to a new stark United Nations report, though, the world is running out of time and only has about 11 years until shit really starts to go down.

The EU is agreeing its position on climate change ahead of COP24.

Working Group I assesses the physical science basis of climate change; Working Group II addresses impacts, adaptation and vulnerability; and Working Group III deals with the mitigation of climate change.

Commitments to cutting down carbon dioxide (CO2) emissions, submitted by 195 nations under the Paris agreement, will fail to keep the rise in global temperatures under 1.5°C of pre-industrial age levels, says the report released in South Korea's Incheon on Monday.
