megadams march on

Open Archive Day

A year ago, I reported how the inflationary spread of megadam projects in tropical countries may do the environment more harm than good. The thing is that submerged vegetation in large reservoirs in the tropics can release enough greenhouse gases to wipe out the climate benefits from the hydroelectric plant in comparison to a modern gas-fired power station.

However, the megadam mania has marched on regardless. Earlier this year, for instance, the Guardian asked:

Why is Latin America so obsessed with mega dams?

and concluded that other renewable energies may be preferable in many cases. Some projects have in fact been stopped by protests and environmental concerns, but in many places, the mania continues.

galician news

It looks like I have inherited the admin side of Oxford's Galician session, after the founder and all-round musical genius Mano has left town. At the same time I realised that I had a WordPress account that I haven't used in 10 years, so I will now advertise the sessions and generally rave about Galician music there as well as in the Facebook Group which I've just set up.

So, you choose:

Galician Session Oxford (WordPress blog)

Galician Session Oxford (Facebook group)

Oh, and I'm also running an email list, but that will only involve one mail per month, just the reminder I'll send one week ahead of the session. Drop me a note if you want to get on that list.

The sessions will continue to happen at the James Street Tavern, last Wednesday of every month, 8:30pm.



I will never get bored of the illustrations from the Cantigas de Santa Maria.

becoming a plant

Today's issue of Current Biology has a special section called

The making of a plant


with lots of fascinating stuff on everything plant related from cell biology to agriculture.

My contribution is a feature rounding up various ways in which mimicking plants can be useful for us, from architecture through to ecology and behaviour of pollinators:

a flood of floods

Open Archive Day

With the recent "unprecedented" floods in Texas and India, we have gained further examples demonstrating what catastrophic climate change will look like on a regular basis. For most people a warmer climate will not mean relaxing by the pool, but fleeing floods and other disasters.

The connection is quite simple really. Warmer sea surface water allows storms to pick up more water vapour and more energy, both of which make them more devastating. I've discussed all this in a feature published early last year, which is now on open access:
