Ex-EPA chief says burning coal is worst thing for climate change

Key points in the report include maintaining the current global temperature at 1.5ºC.

Where Has The Warning Come From?

The US president was visiting Florida, a state particularly vulnerable to sea level rise and now in the path of Hurricane Michael, when the UN Intergovernmental Panel on Climate Change report warned on Monday that "unprecedented" changes were needed to stave off dire impacts if the world warms 1.5C beyond the pre-industrial period.

"When it comes to coal, Australia is the world's biggest drug dealer." he said.

Very - the report calls for "rapid, far-reaching and unprecedented changes in all aspects of society".

The report is based on an analysis of more than 6,000 scientific papers, reviewed by climate scientists from 40 countries. "The further we go the more explosions we are likely to set off: 1.5C is safer than 2C, 2C is safer than 2.5C, 2.5C is safer than 3C, and so on", he said.

A landmark United Nations report paints a dire picture of the catastrophic consequences the world will face if immediate action is not taken to limit the global warming to 1.5°C, warning that at 2°C, the world could see 10 cm more global sea level rise, loss of all coral-reefs and worsening food shortages.

"Scientists might want to write in capital letters, 'ACT NOW IDIOTS, ' but they need to say that with facts and numbers, and they have", said Greenpeace climate activist Kaisa Kosonen, who was an observer at recent IPCC meetings.

"Every extra bit of warming matters, especially since warming of 1.5 C or higher increases the risk associated with long-lasting or irreversible changes, such as the loss of some ecosystems", said Hans-Otto Pörtner, co-chair of one of the IPCC groups, in a news release.

How Can Cuts Be Achieved?

Human-produced Carbon dioxide emissions would have to drop by 45 percent from 2010 levels by 2030, reaching "net zero" by 2050, according to the report. Any additional emissions would require removing Carbon dioxide from the air.

"We need the political leadership and the decisive action".

"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.

Experts estimate that cutting down on SLCPs could reduce global warming by as much as 0.5 degrees C. That would not be enough to avoid the worst effects of climate change if we continue to burn fossil fuels, but it could buy humanity some much-needed time while carbon emissions are brought under better control. By 2100, we're on track to see more than 3 C above pre-industrial levels.

Global temperature is now rising 0.2C with each decade, and it is estimated we will reach 1.5C by 2040. Even at the current level of 1°C warming, it is painful.

Sea levels, for example, would be 10cm lower in a 1.5 degree scenario than a 2 degree scenario, and there would be substantially fewer heatwaves and droughts.

Deep in the report, scientists say less than 2 percent of 529 of their calculated possible future scenarios kept warming below the 1.5 goal without the temperature going above that and somehow coming back down in the future.

Health benefits will also be experienced as we will see lower levels of air pollution and the alleviation of poverty in the developing world. "From a climate perspective, nothing is worse than burning coal", former EPA Administrator Gina McCarthy told a Financial Times climate finance summit in London. We can't find any historical analogies for it. "In the near term, taking fast, ambitious action to reduce SLCPs is particularly vital to keeping temperature rise below 1.5 C", the authors said.

"We need to extend this kind of progress on renewables to other areas".

Taking excess carbon from the atmosphere requires measures such as planting new forests or, more controversially, burning plant material for energy and capturing the carbon to store underground, which is known as "BECCS". Emissions of other greenhouse gases, such as methane, also will have to drop.
