Someone had to say it.
On Monday, the chief scientist from the Met Office confirmed what lots of people suspected: "all the evidence suggests" that the storms and flooding we've seen across the UK are linked to climate change.
Normally, we like to focus on the practical stuff - the things you can say 'yes' to, and the carbon cutting progress being made all over the world.
We know from talking to you that taking action feels good. It's satisfying to solve a problem or cement a good habit, but that also means it's easy to lose sight of the big picture.
But when the reality of climate change starts coming up through the floorboards, it's worth pausing to remember why we do this, and why it's so important.
Ladies and gentlemen, prepare for the Energy Bill Revolution!
Ok, it's less incendiary than it sounds – more selfies in scarves than manning the barricades.
But the EBR campaign is tackling a serious problem, and they're not afraid to think big.
Britain's houses are some of the least insulated in Europe, which means we waste loads of energy heating the air outside. If you're rich, that's pretty annoying – you get a giant carbon footprint and nothing to show for it.
But if you're poor, it can be deadly. When people are having to chooose between heating and eating, you know there's got to be a better way.
LED lights have come a long way.
This is a technology whose time has come, but making the switch at home isn't always that straightforward. With so many options, a new way of measuring brightness and massive differences in quality and price, this can be confusing territory.
So we've enlisted LED expert Simon Brammer to answer your questions. A programme manager at Ashden by day, Simon successfully LEDified his home a while back, and has been advising friends and family on the subject ever since.
There's three ways to ask a question:
We'll publish all the questions and answers here in the next couple of weeks – watch this space!
A lot has changed in 40 years. Disco is now retro, flares are set off at football matches, and the Good Life is a vague aspiration, rather than a TV show. All this you already knew.
But did you also know that carbon dioxide emissions from heating, lighting, and electrifying an average UK house have almost halved in that time?
