Not well at all, according to the scientists. Actually it is a travesty of language to call Abbott’s position “science”. In this piece I’ll highlight the kind of thinking that unfortunately cannot be dismissed as an Abbott aberration, but has the Turnbull government in it’s thrall. Let’s start with David Rowe’s amazing cartoon from the AFR:
On Monday and Tuesday this week we are going to have the AFR national Energy Summit in Sydney with everyone there, including Josh, Jay, Bill, Andrew Vesey and a different Malcolm Roberts (Chief Executive, APPEA). Should be fun.
The Weekend AFR had about half a dozen articles, led off by an article by Ben Potter, Angela Macdonald-Smith and Mark Ludlow (no doubt pay-walled) which said our energy has become dirty, expensive and annoyingly unreliable. They reckon something has to be done, it’s just that:
the causes identified by Prime Minister Malcolm Turnbull – or unofficial backbench energy spokesman Tony Abbott – are not the same as the causes power industry experts and regulators highlight. Continue reading Climate clippings 117
For me the main point of George Monbiot’s article about Hurricane Harvey is that the course we are currently on to achieve 3.5 to 4°C of warming by the end of the century is equivalent in magnitude to the change between the last ice age and the balmy times of the Holocene. To talk about whether this or that extreme weather event was caused by anthropogenically induced climate change seems beside the point.
The short answer is that everything about the climate has changed, so we are experiencing a climate that is different from how it would have been, and it will change much more during the life spans of the next few generations. Generally speaking, as Climate Central’s Climate Extremes Index indicates, extreme weather events are on the increase: Continue reading Storms for our grandchildren
1. Trump’s climate vandalism continues
Trump has picked a Republican politician, Rep. Jim Bridenstine of Oklahoma to oversee NASA, a job that often goes to astronauts or scientists.
- Bridenstine, who is the former executive director of the Tulsa Air and Space Museum and Planetarium, said in a 2013 speech on the House floor: “Global temperatures stopped rising 10 years ago. Global temperature changes, when they exist, correlate with sun output and ocean cycles.”
Well, not everywhere, it’s dry here this winter, but definitely in Texas, and in India, Nepal, Bangladesh and now Pakistan. In fact, in the Indian subcontinent more than 1,400 people are dead since the recent rains started, and more than 45 million are directly affected, many having had their livelihoods destroyed. Mumbai, a city of some 20 million people, had a month’s rain in a single day. Two-thirds of Bangladesh was said to be under water. Here’s an early map from August 29:
We plant about 9 billion trees each year. Unfortunately we also clear about 15 billion, leaving a deficit of 6 billion.
A system of using drones is being developed which could plant trees at 10 times the rate of hand planting and at 20 per cent of the cost by firing germinated seeds into the ground. Continue reading Climate clippings 211
Quiggin says, yes we can.
I can’t comment on his blog, because the Askimet software has got me marked as a pest, and my comments go straight to spam. There is no facility for telling Askimet I’m OK, so there it is, I’m as good as banned. So I’ll make my comments here, which are in any case longer than is form for comments there.
For me the crux of the report is this, from a discussion piece at The Conversation:
- The report predicts that half of the world’s identified tipping points – such as the collapse of polar ice sheets and the drying out of the Amazon rainforest – would be crossed under 2C warming, compared with 20% of them at 1.5℃.
If we go to 2℃, we will have a very different climate and there is a good chance we won’t be able to stabilise there. The bad news is that if we just carry on we’ll reach 1.5C by 2024, and 2C by 2036. Continue reading Science shows the need for urgent climate action
Ootz’s recent comment raised the question:
should we be seriously looking at what the safe levels of CO2 in the atmosphere are for human beings?
That was in the context of an informed comment that we have not seen CO2 levels above 320 ppm for 27 million years, which predates hominid evolution. Studies indicate that 600 ppm globally, which is where we could be by 2050, might just render us extinct.
To jump to the chase, we don’t really know what the full effects of elevated CO2 will be, or indeed what they are now. However, indications are that as CO2 rises, our brains will work less well and we will become more limp and sluggish. A bit like a frog in a pot of water gradually being heated. Continue reading CO2 is scrambling our brains, but will it kill us all?
1. Adani proposal to get free coal for five years
The ABC has got wind of a story that Adani, if the Carmichael coal plant goes ahead, will pay only token royalties to the Queensland Government.
Whether true or not here is a big handshake:
As linked by zoot on the last CC, pathogens are emerging as the permafrost melts, some capable of becoming active after long periods of time, even millions of years. There has been one case of anthrax becoming active after being frozen in a dead reindeer for 75 years. Continue reading Climate clippings 206
