On Friday, I passed my PhD viva @UniofOxford with minor corrections! Thanks to Neil Hart (Oxford) and Wilfried Pokam (Yaounde I, Cameroon) for examining! @oxfordgeography @NERCscience @OxfordEnvRes @RMS_Oxford @SimonDadson @Wash_Oxford

Interesting that the joint 13th hottest day on record didn’t even warrant an amber extreme heat warning… I know that the criteria for an extreme heat warning includes several other factors, but I’d really like to understand the thought process better.

📰 Seen some curious online headlines around summer rain?

Here's our #FactCheck on the reports 👇

Roy Hodgson has stepped down from his post as first-team manager.

We thank Roy for his outstanding service, in which he managed 200 games across six seasons.

[Ed Hawkins @ed_hawkins]

Would you like to help climate scientists?

If so, today we launch our latest #WeatherRescue project.

Join other volunteers to transcribe lost weather observations. The mission is to recover pressure measurements taken in Oxford between 1828-1860.

Newest @WWAttribution rapid analysis out, showing that Libya floods may have been made up to 50 times more likely due to our burning of fossil fuels!

Yet, important to note that the level of regional vulnerability is as extreme as the event itself.

[Dr David Crowhurst @crowdave]

@mattletiss7 Weather forecasts depend on a highly accurate initial state, and small differences with reality quickly diverge with time to generate errors. Climate predictions focus on slowly varying boundary conditions instead, such as CO2 and radiation, leading to more reliable predictions!

WHY ARE ENERGY STANDING CHARGES SO HIGH?
The high energy standing (daily) charges are a moral hazard and should be reduced. It is outrageous that people have to pay £300/yr just for the facility of having gas & electricity even if they use none.

While energy price cap & bills drop an avg 17% this Sat, that ISN'T equal for all:-

- Standing charges remain unchanged
- Elec unit rate is dropping roughly 10%
- Gas unit rate is dropping roughly 25%

So higher users, especially with gas will see a bigger than 17% drop. Lower users, especially electricity only, will see a lower than 17% drop.

Keeping the standing charge high means lower users can save proportionately less and less by reducing usage - that disempowers them.

I have long campaigned for lower standing charges. MSE is submitting a consultation on this about shifting some of the cost the the unit rates.

The reason Ofgem mandates firms to have high standing charges in the price cap is because they use it to pay for the 'fixed costs' of energy (distribution, transmission etc) - which it believes should be mostly shared equally.

It is especially loaded onto the electricity standing charge as that is 'more universal'.

I think a more progressive split would be better, by putting a bigger proportion of the cost on the unit rate. And in past polls I've done on here the huge majority agree.

One stumbling block is the argument from Citizens Advice, an organisation I have great respect for. Its concern is that if you shift the burden, some vulnerable people with disabilities and medical issues that make them high users will suffer.

Of course the correct solution to that is lower the standing charge but give them separate support. Yet that would involve an energy market that wasn't broken and the regulator and government to operate in concert.

So we're in a chicken and egg situation. Still on balance I think the fair thing to do is lower the standing charge (and campaign for help for the high using vulnerable at the same time). Yet I wanted to bash this out quickly as I saw much debate on it after my earlier tweets, and I wanted to explain some of the bigger picture.

This really is no joke. People act like toxic environments in research is the price we have to pay for genius to succeed. But have we considered that there might be more success in positive work environments where everyone feels properly supported? /1

Nuneham viaduct update: I’m hearing no trains will run until early June, after which a temporary structure will allow at least limited low speed services. After that, a permanent repair to the existing structure is proposed.

Snowfall Outlook - today

[UPDATE 3] This is the last update for today's significant snow event. Significant snowfall totals expected across N/NE England into Midlands with further significant snow south of the M4. Some spots may see 30-40cm by the end of the day.

How wet has March been where you are? ☔

With a day in the figures still to be added, it will be in the top 10 wettest Marches on record for England, Wales and Northern Ireland.

NERD ALERT...the atmospheric heights will be SO LOW tonight, anyone living above 4,000 ft or so (hello top of Mount Washington) will be in a different atmospheric layer entirely, the stratosphere! This layer is typically 4-12 miles up, but tonight it will be less than a mile!

In spectacular fashion the GFS has folded.

GFS ticket holders are reminded that tickets are non-refundable, a taxi will collect you from the end of the garden path shortly.
