Climate emergency: world ‘may have crossed tipping points’

Warning of ‘existential threat to civilisation’ as impacts lead to cascade of unstoppable events

The world may already have crossed a series of climate tipping points, according to a stark warning from scientists. This risk is “an existential threat to civilisation”, they say, meaning “we are in a state of planetary emergency”.

Tipping points are reached when particular impacts of global heating become unstoppable, such as the runaway loss of ice sheets or forests. In the past, extreme heating of 5C was thought necessary to pass tipping points, but the latest evidence suggests this could happen between 1C and 2C.

The planet has already heated by 1C and the temperature is certain to rise further, due to past emissions and because greenhouse gas levels are still rising. The scientists further warn that one tipping point, such as the release of methane from thawing permafrost, may fuel others, leading to a cascade.

The researchers, writing in a commentary article in the journal Nature, acknowledge that the complex science of tipping points means great uncertainty remains. But they say the potential damage from the tipping points is so big and the time to act so short, that “to err on the side of danger is not a responsible option”. They call for urgent international action.

Statement on the Climate Crisis: Revised

Spread the love

The Earth’s climate is in crisis, it is an emergency. There is no doubt about it – scientists are in near unanimous agreement that humans are causing severe damage to Earth’s climate. This is our home and we have to care for it. I particularly feel for future generations – our children and their children – who we have failed. I propose that the appropriate response is that we do whatever is necessary and that we have already delayed too much.

[Revision 28/11/19

There is a clear Left vs. Right political orientation divide on the need for urgent action to address the climate crisis. It is within right-wing politicians that – despite the absolute deluge of evidence – deniers of human-caused climate change are found, figures such as Donald Trump and Nigel Lawson in the UK. It is within right-wing political parties – in the UK the Conservative, Brexit, UKIP and the Neo-Liberal Liberal Democrats parties – that there is little appetite for emergency action to reduce damage to the climate from human actions.

We need to prevent Climate change deniers and those most resistant to climate action i.e. the right-wing, from getting elected and being in positions of power.]

While I am no expert there are plenty of experts and we should listen to them.

This post is to be revised and elaborated.

World Scientists’ Warning of a Climate Emergency

Scientists have a moral obligation to clearly warn humanity of any catastrophic threat and to “tell it like it is.” On the basis of this obligation and the graphical indicators presented below, we declare, with more than 11,000 scientist signatories from around the world, clearly and unequivocally that planet Earth is facing a climate emergency.

Mitigating and adapting to climate change while honoring the diversity of humans entails major transformations in the ways our global society functions and interacts with natural ecosystems. We are encouraged by a recent surge of concern. Governmental bodies are making climate emergency declarations. Schoolchildren are striking. Ecocide lawsuits are proceeding in the courts. Grassroots citizen movements are demanding change, and many countries, states and provinces, cities, and businesses are responding.

As the Alliance of World Scientists, we stand ready to assist decision-makers in a just transition to a sustainable and equitable future. We urge widespread use of vital signs, which will better allow policymakers, the private sector, and the public to understand the magnitude of this crisis, track progress, and realign priorities for alleviating climate change. The good news is that such transformative change, with social and economic justice for all, promises far greater human well-being than does business as usual. We believe that the prospects will be greatest if decision-makers and all of humanity promptly respond to this warning and declaration of a climate emergency and act to sustain life on planet Earth, our only home.]

Jeremy Corbyn to announce Labour manifesto

Spread the love

UK’s Labour party leader Jeremy Corbyn is announcing the Labour manifesto today.

While I am not and have never been a Labour member, I strongly support the current Labour party and their policies. Jeremy Corbyn and the Labour party are presenting a real alternative. Instead of sucking up to the rich and powerful they are going to represent ordinary people.

How on earth is democracy so perverted that the rich increase their obscene wealth while we have so many people freezing to death homeless on the streets and so many of the working poor relying on food banks? (The Tories’ Universal Credit has no doubt hugely contributed to that actually.)

I am concerned with delay in addressing the climate crisis. Knowledgeable scientist are virtually unanimously agreed that action needs to be taken immediately.
