New research estimates that a worldwide planting programme could remove two-thirds of all the emissions that have been pumped into the atmosphere by human activities, a figure the scientists describe as “mind-blowing”.

This is the kind of geoengineering, if any, I would be comfortable with. It seems achievable too, and for a reasonably affordable amount of money.
There are some, however, who believe that these dirty monoliths of the oil age can instead be rehabilitated – they want to transform them into sources of clean, renewable energy. Engineers believe it is possible to use the vast hull of oil tankers to create floating power stations that can convert the ocean swell into electricity. This is the ambitious plan to create the world’s first “waveships”.

Really interesting article about the future repurposing of oil tankers as mobile power stations which could act as large battery banks to plug into shore, desalinate water, liquify gasses or even function as factories mid voyage.

The UK already has a 2050 target – to reduce emissions by 80%. That was agreed by MPs under the Climate Change Act in 2008, but will now be amended to the new, much tougher, goal.
The actual terminology used by the government is “net zero” greenhouse gases by 2050.

One million animal and plant species are now threatened with extinction.
Nature everywhere is declining at a speed never previously seen and our need for ever more food and energy are the main drivers.
These trends can be halted, the study says, but it will take “transformative change” in every aspect of how humans interact with nature.

If you haven’t watched yet, I urge you to do so.
It’s not often that a viral hashtag on social media goes, well, beyond social media.
But an online challenge encouraging users to clean up places has seen tens of thousands of people doing just that.
In the Trashtag Challenge, users pick a place filled with litter, clean it up, and post before and after pictures.
Volunteers have made beaches, parks and roads trash-free while also raising awareness of the quantity of plastic litter we produce.

Made from recycled PET, the bottle has a plastic cap, making recycling easier. It takes up 40% less space and is 87% lighter than conventional bottles.
The company’s carton for 10 flat bottles, being launched at a packaging conference in Birmingham on Wednesday, would hold only four glass bottles of the same 75cl volume.

Some impressive savings from some innovative thinking – so much so that the wine industry have to put traditional glass bottles aside and look at this soon.
Swifts are incredible birds, spending most of their lives on the wing and only landing when it’s time to nest. After flying its nest for the first time, a young swift may spend two or three years in the air, eating, drinking, sleeping, bathing and even mating! The swifts that nest in the UK arrive here in late April – May and may spend just 3 months with us; soaring and swooping over rooftops catching insects to eat.
But they’re in serious trouble here, with numbers down to less than half of what they were just twenty years ago. Modern buildings lack the nooks and crannies they need, and swifts are struggling to find homes.
Fortunately there are ways to help these birds. There are special swift nestboxes available, and if you’re having a building constructed or renovated, there’s also the option of the ‘swift brick’. This replaces a standard house brick and can easily be installed by a builder. Swift boxes and swift bricks can work especially well when put up in groups, as these birds like to be near other swifts.

Buying organic food is among the actions people can take to curb the global decline in insects, according to leading scientists. Urging political action to slash pesticide use on conventional farms is another, say environmentalists.
Intensive agriculture and heavy pesticide use are a major cause of plummeting insect populations, according to the first global review, revealed by the Guardian on Monday. The vanishing of insects threatens a “catastrophic collapse of nature’s ecosystems”, the review concluded, because of their fundamental importance in the food chain, pollination and soil health.
