2019 may go down in history as Year Zero of the climate apocalypse. The tsunami of extreme events has been so relentless that each is quickly forgotten in favour of its successor. So before the year ends we should pause, remember just how extraordinary it was, and reflect on what this might mean for our future. The year started with a record-breaking heatwave in southern Australia with temperatures in the mid-40s, in some areas for 40 days in a row. Then followed the immolation of vast areas of moist Tasmanian forests, forests that date back to the last ice age.

Approximately 3% of the state burned as a long-term trend of less rainfall and more evaporation was capped off by the driest January on record. On the mainland, who could forget those horrifying images of the Menindee fish kills?

1. Leadership is REALLY important

COP25 in Madrid only happened because the Chilean government, faced with mounting civil disorder, decided to cancel the meeting in Santiago. Spain stepped in and in three weeks organised a well-resourced and well-run event. However, the fact that it was being run by one government, while hosted by another, gave rise to severe difficulties.

Delegates were highly critical of the fact that when it came to the key text about ambition, the Chileans presented the lowest common denominator language first, resulting in a huge number of objections from countries eager to see more ambition on carbon cuts. Experienced COP watchers said they should have started with high ambition and negotiated down to a compromise.

Insiders say that agreement was only found becaus...

What happened in week one?

The COP25 climate talks in Madrid may have officially opened on Monday 2 December, but they only really started on Friday evening. That was when Greta Thunberg arrived to join a 500,000-strong march through the centre of Madrid, demanding that world leaders listen.

The young activist said that she, and the millions who have marched and protested around the world in the last two years, had “achieved nothing” because greenhouse gas emissions have continued to rise...

The world’s oceans are gasping for breath, a report issued Saturday at the annual global climate talks in Madrid has concluded. The report represents the combined efforts of 67 scientists from 17 countries and was released by the International Union for Conservation of Nature. It found that oxygen levels in the world’s oceans declined by roughly 2 percent between 1960 and 2010. The decline, called deoxygenation, is largely attributed to climate change, although other human activities are contributing to the problem. One example is so-called nutrient runoff, when too many nutrients from fertilizers used on farms and lawns wash into waterways.

The decline might not seem significant because, “we’re sort of sitting surrounded by plenty of oxygen and we don’t think small losses of oxygen a...

The world’s leading climate science organizations have joined forces to produce a landmark new report for the United Nations Climate Action Summit, underlining the glaring – and growing gaps – between agreed targets to tackle global warming and the actual reality.

The report, United in Science, includes details on the state of the climate and presents trends in the emissions and atmospheric concentrations of main greenhouse gases. It highlights the urgency of fundamental socio-economic transformation in key sectors such as land use and energy in order to avert dangerous global temperature increase with potentially irreversible impacts. It also examines tools to support both mitigation and adaptation.

“The Report provides a unified assessment of the state of our Earth system under the...
