Can you find London?

This is well worth a play- what would the world look like if all of the ice melted? Toggle cities on for it to really hit home.

It is unclear from this if they’ve included the thermal expansion that would take place in the oceans if the earth was warm enough for all the ice to melt- sea levels also rise as the ocean warms so if this isn’t included the sea level rise in some areas would be significantly larger than this.

If the Larsen C ice shelf (the one I look at) collapsed it wouldn’t contribute to sea level rise directly, but the glaciers feeding it are likely to speed up and this will, and by how much is unclear.

Lego cake- a quick how to



IMG_20140419_183719227

I’ve called this a quick how to as it’s not a step by step guide- at the time I wasn’t sure how it would work so this is more how I did it and what I picked up along the way.

  • The key thing is it needs two layers of icing, if you try and stick the lego pieces straight to buttercream it’ll just creep up between the pieces and generally get sticky and messy. So first do one really thin layer of white (or marzipan), it doesn’t need to be neat and can even crack a bit, no-one will see. Then add lego and the main white icing layer. Stick the blocks using a pastry brush and a watery glace icing (icing sugar mixed with water), but in very very small amounts as the colours will run and spread everywhere.
  • It’s best to have a template (baking paper works fine) to mark out the area you want to be lego. Mark this gently into the base white layer, then add the lego blocks. Use the template to cut this area out of the main layer of white icing when you roll it out before it goes on the cake (but leave it attached in the centre so you can roll it up once it’s on the cake). If you try and cut this once it’s on the cake the edges get messy and it’ll stick to the lego blocks and probably get nice blue smudges.

  • The blocks are most easily done by rolling a flat sheet then cutting rectangles out of it. It’s much quicker than molding each one individually and if the edges are a bit rough they get joined together anyway. Same with the dots on top of the lego, it’s easier to make a long sausage and cut pieces off. The blocks on top will need individual molding though.
  • A note on icing: if you’re UK based Asda is best by far in terms of price and range. You can buy a small pack of a selection of coloured pieces (which will easily do this cake twice over) for just over £2, Tesco and Sainbury’s charge that for one block of one colour.
  • A square cake would have been easier…

An interesting thought on solar energy

So this one’s not technically ice related but as what I do is mot likely only relevant due to global warming then climate change and renewable energy may be things that feature occasionally. This image floats around the internet and appears from time to time but I think it’s such a good visual piece of information it’s worth promoting.

This image shows how much space would be needed for solar power plants to power the World. Now obviously we can’t just go bunging huge great solar panels all over the Algerian/Libyan desert- there are issues with storage and transportation before you even get on to the intermittent nature of solar energy. Solar is definitely not a complete solution, but the relative area here is certainly worth thinking about.

Countries like Germany are way ahead of us here in the UK in terms of solar and even though we may not be the best candidates for solar power plants there are plenty of places that are.
