North pole changes places

Climate change has many impacts on the planet, and researchers recently discovered another striking one: North Pole is moving. It’s not the ice masses in the Arctic, but acually the Northern pole of the earth’s magnetic field.

With help of satellite measurements, scientists figured out that the pole is shifting about 20 centimeters per year towards Greenland. Position of the magnetic field’s poles is determined by mass distribution around the planet. This mass distribution changes due to climate change: Accelerated melting of the poles account for 90 per cent of the movement, the study concludes.

You wonder about the remaining 10 per cent? Well, you might not have known yet (so did we) that the pole is constantly moving as earth’s mass distribution changes anyway seasonally/continuously by snow- or rainfall or continental drift. The movement due to melting ice sheets adds up on this trend. For scientists, this is more than just a “nice-to-know”-fact: the satellite measurements can help climate researchers to tell, where ice is lost and in consequence provide more detail to predict climate change impacts.

Coral collapse considered evitable

Normally, we mostly present you animals threatened by climate change – but this time, we have some good news for you: Researchers recently found out that there is a way corals might actually survive the multiple threats of humanity. We actually give these small creatures a very hard live:  pollution, overfishing and last but not least climate change. The latter influences the reefs by ocean acidification and rising sea temperatures.

For a long time it was thought that those cnidaria folks won’t cope with those impact. But the new study gives a glimpse of hope: If we manage to lower CO2 emission under the current level and stop overfishing, then all reefs with more than 20 per cent coral cover will survive. That’s the only chance, the researchers figured out.

For their work they took into account models for climate change, ecosystem dynamics, and carbonate processes. That way they could show that fish colonies are crucial for corals to survive, as they eat away straggling algae on the reefs resulting in more space for corals to grow.

Eat (more) insects!

(CC BY SA 2.0 unnormalized)

Ever wondered what you could do to fight climate change, but never came up with a proper solution? A quiet common way is to switch to a vegetarian diet, as meat production accounts for about 30 per cent of greenhouse gas emissions. If you can’t do without your daily portion of proteins (aka meat) – here might be a convenient idea: Eat more insects! This is not a suggestion of some weird person being anxious about animals with too many legs and wants them to go extinct. It’s a seriously meant proposal from the UN to feed the booming population all over the world.

If a simple recommendation is not good enough for you, but you need some convincing numbers- the New Scientist has put them down:

To produce 1 kilogram of beef, for example, you need 10 kg of feed, whereas 1 kg of crickets requires just 1.7 kg. What’s more, 80 per cent of a cricket is edible compared with just 40 per cent of a cow.

In consequence, much less land would be needed to grow food for our food (as insects could even grow on kinds of waste) – we would get more food from the same amount of grain and would thereby cut pollution.

This kind of diet is already familiar in some parts of the world, yet the most consumed are beetles, ants and bees. In total 1,900 insects have been identified to be suitable for human diet.

But for lots of people it is quite unthinkable to take a bite. What’s your opinion: Is the argument of sustainability strong enough to change people’s minds?

Jane Goodall: 300 days on the road for the cause

Meeting Jane Goodall, British primatologist and avid environmental activist, is an honour. Global Ideas took the opportunity to talk with the world’s foremost expert on chimpanzees during a film screening in Brussels. The documentary Love MEATender focuses on earth’s growing hunger for more meat and the price we already have to pay for the excessive consumption.

A lot of people are already aware of the situation we are in, Goodall says. But that does not automaticly change something:

One of today’s main problems is that earth’s population is growing fast and with it the number of people who want to consume meat, Goodall adds. As the middle classes in the developing world are rising up, they want to have the same standards of living as the industrialized countries have. “Which is of course understandable.” But the planet is not growing, so it won’t be able to support this lifestyle much longer.

For Jan Goodall the newest generations are the key to a solution. Her organization, the Jane Goodall Institute, runs an initiative called “Roots and Shoots program,” with the goal to “provide young people with the knowledge, tools and inspiration to improve the environment and the quality of life for people and animals,” as the program’s website says. “We need to train a new generation to be better stewards than we have been,” she adds. Otherwise there would be absolutly no point:

A Song, a Dance and Spots on the Fight Against Climate Change

Yesterday, the colossal efforts each and every one of us put in the project came to fruition as the pinnacle of our project, the 1st world youth sustainability summit, came to be.

The event, many of whose attendees were project managers and leading figures in their respective fields, were pleasantly surprised as the youthinkgreen teams that took part in the gala showed discipline, determination and that they were not to be discouraged by the sheer size and importance of the event at hand.

The program, whose highlights were the youthinkgreen rendition of the song ,,Mut zum Handeln” (courage to act), the various student-produced environmentally oriented spots, and the Indian dance showed the unique inter-cultural connection between the various members of the Youthinkgreen.

The excitement at the event rubbed off on each and every one of our guests, with many of them on the verge of euphoria. We were standing hand-in-hand with people whose success has come to be known on every continent of the planet and watched in amazement as they relaxed and spoke to us as peers, not as minors, as friends not as climate change fighters.

All in all, to simply call our summit a success would be an understatement. The Allianz Forum will forever in our hearts be remembered as the place where we graduated into adults, supported along our journey by the constant recognition we received throughout the process.
