…The German oceanographer and climatologist Stefan Rahmstorf writes: “We have enough ice on Earth to raise sea levels by 65 metres – about the height of a 20-storey building – and, at the end of the last ice age, sea levels rose by 120 metres as a result of about 5C of warming.” Taken together, these figures give us a perspective on the powers we are dealing with. Sea-level rise will not remain a question of centimetres for very long.

..Saving the world is voluntary. You could certainly argue against that statement from a moral point of view, but the fact remains: there are no laws or restrictions in place that will force anyone to take the necessary steps towards safeguarding our future living conditions on planet Earth. This is troublesome from many perspectives, not least because – as much as I hate to admit it – Beyoncé was wrong. It is not girls who run the world. It is run by politicians, corporations and financial interests – mainly represented by white, privileged, middle-aged, straight cis men. And it turns out most of them are terribly ill suited for the job. This may not come as a big surprise. After all, the purpose of a company is not to save the world – it is to make a profit. Or, rather, it is to make as much profit as it possibly can in order to keep shareholders and market interests happy….

Humans are filling the world with trash, but not all of our waste is visible to the human eye.

While plastic litter on the beach is easy to spot, microplastics and ‘forever chemicals’ have leached far and wide without our barely noticing.Both forms of pollution are now so ubiquitous in the environment, they are falling with the rain. But while the potential threat of microplastics is a regular point of discussion, some researchers argue the spread of other persistent synthetic compounds is comparatively overlooked.

A team of scientists in Europe are now worried we have crossed a critical line. They argue the presence of forever chemicals in our hydrosphere at values that exceed key guidelines means we have entered an unsafe operating space from which there is practically no return.

The warning comes on the heels of another cautionary paper, which argues the world has breached the safe planetary limit for synthetic chemicals.

Climate-change-denying politicians love to attack the IPCC as alarmist. It pleases the fossil fuel barons who fund them. But if anything, the IPCC has likely underestimated the role climate change is playing in the increase in persistent weather extremes we’ve seen in recent summers.
One of us has collaborated on research investigating how the asymmetric pattern of the warming of Earth’s surface (wherein the polar regions have warmed more than the middle latitudes) alters the behavior of the summer jet stream. Specifically, it favors a tendency for high-amplitude meanders of the jet stream that remain locked in place, leading to highly persistent deep high and low-pressure centers associated, alternately, with extreme heat, drought, wildfire or extreme flooding.

The policies currently in place to tackle the climate crisis around the world will lead to “catastrophic” climate breakdown, as governments have failed to take the actions needed to fulfil their promises, three former UN climate leaders have warned.

There is a stark gap between what governments have promised to do to protect the climate, and the measures and policies needed to achieve the targets. At the Cop26 summit last November, countries agreed to bring forward plans to limit global heating to 1.5C above pre-industrial levels – the limit of safety, according to scientists. They have so far submitted pledges that would limit temperatures to under 2C.

But the policies and measures passed and implemented by governments would lead to far greater temperature rises, of at least 2.7C, well beyond the threshold of relative safety, and potentially as much as 3.6C. That would have “catastrophic” impacts, in the form of extreme weather, sea-level rises and irreversible changes to the global climate.

The war in Ukraine is also having ripple effects throughout the global system: food and fuel prices are soaring, leading to political destabilization in many countries around the world, European attitudes about defense spending have dramatically changed, war mongering in the US has once again reached an all-time, and even China is putting on display its global reach ambitions by delivering missiles to Serbia, a traditional Russian ally.

Last, but not least, the war in Ukraine is pushing climate action aside even though most countries are falling short on their climate goals.
