A team of researchers at the University of New South Wales has broken its own record for photovoltaic efficiency. This advance comes through use of what are called “multi-junction” solar cells that use prisms to split sunlight across its spectrum, to hit multiple receptors targeted at different wavelengths.
I recently came across an article titled “What will it take for people to care about climate change?“. There are a lot of articles like this, all of them focused on some disaster linked to climate change. This one touches on the current heat wave in India, which has seen the highest temperature ever recorded in that country. This is the second year in a row in which the country had a heat wave that caused roads to melt.
“What will it take?” is a fair question to ask, but I think it may be the wrong question, at least if asked by itself. I think if you polled the planet, most people would say they care about climate change. Even if you polled the United States – a country famous for its science denial, it seems a majority of people care about the issue, at least to some degree. The problem is what that actually means.

Over the last couple weeks I’ve had a combination of events that have kept me from being able to blog. Primarily, a health problem and a re-assessment of funding at work that means I’m now working half-time instead of full time.
The downside of all this is that I don’t currently have the funds to hire other writers for a series I had planned, so that’ll have to go on hold for a while. The upside is that I now have a lot more time for blogging and fiction writing. Starting Friday, I’ll be doing about one in-depth blog post about some aspect of climate change per week, plus a higher volume of less time-consuming posts, so this will become a more interesting place for all of us.
I’m also going to re-vamp my patreon page and put a link to that where it’ll be easier to find, so if you decide you like what I’m doing, and want me to do more of it, you will have the ability to make that happen! More on that later.
Anyway, I just wanted to drop a post to say I’m back in action, and stay tuned!
It’s starting to look like readers living in the ocean may need to develop the means to move onto land. More on why later, but for now, here’s how I recommend you arrive. Singing about deities is likely to put land-dwellers at ease, and this demonstrates some knowledge of some of our cultures.
Hillary Clinton recently tweeted a rejection of any perceived endorsement from Charles Koch, citing his climate denial, and his funding of misinformation efforts. I take it as a good sign that she’s being clear about that, but I find it a bit frustrating, given Clinton’s own stance on fossil fuels – namely the assumption that there’s a way to continue using them that’s “safe and responsible”:
There’s a lot to be said about the harm that climate change is doing and will do in the future, both to ecosystems and to humanity, but the current system would be horrible, dangerous, and inhumane even without the destabilization of our climate. Case in point: [Read more…]
I’ve previously mentioned my hobby of talking to/arguing with strangers on the internet, and a while back I decided to copy and paste one of the conversations onto my blog, since it seemed wortwhile. Since then I’ve periodically added to the series when something interesting and fun comes up. So, without further ado, here is the latest installment of Conversations with Strangers, taken from the comments thread of this Huffington Post article.
Stranger:
So if a change in ice mass at a pole can cause the earth to sway from its position, then isn’t it possible over time that population changes could do the same thing? It that is possible, then couldn’t China and other over populated areas produced the same “balance” issue? Now, if this is possible, that could mean that Chna is a leader in carbon emissions and “Population Sway”.
My last blog post covered a dramatic shift in the location of the North Pole, and a change in the direction in which Earth’s axis is migrating, and the wording of the original articles, and subsequent secondary and tertiary articles has been the source of some confusion.
The 75˚ shift refers to the change in direction of polar drift, NOT change in location of the pole. It’s a big change in direction, but nowhere near the kind of change we would see if Earth’s equator suddenly ran through the Arctic and Antarctic. We probably would have felt that.
No really though. It’s always been clear that the worldwide melting of glaciers and ice sheets was going to have some effect on Earth’s crust. Like some other impacts of climate change, it’s a pretty straightforward concept – the crust is a relatively thin layer of solid stuff on top of the molten goo that makes up most of the planet’s bulk, so massive chunks of ice press the layer down. Reduce the ice mass, and the crust rises up a bit.
From there it’s not much of a stretch to predict some change in seismic and volcanic activity as a result.
What had not occurred to me was that this redistribution of mass could actually result in changes in how the Earth moves through space. New research published in Science Advances (yay open access!) indicates that the loss of ice mass in Greenland and West Antarctica, coupled with a gain in ice mass in East Antarctica, has shifted the North Pole towards the UK in the last decade, a change from the direction it was moving for most of the 20th century.
This isn’t a big enough shift to cause problems, bit it is an indication of the scale of the changes that are occurring, thanks to human-caused climate change.
