so can we start blaming this cold and wet spring on La Nina?

No

It has been said for more than a decade, doing little or nothing 'now' will cost far far more in future.

So politicians decide to do little or nothing now.

No we're still in el nino territory, forecast to transition to enso neutral in the next couple of months and then La Nina forming later in the year albeit with only 60% probability (certainty will improve over the next couple of months once the so called 'spring barrier' has passed)

 

Global av temp for April will almost certainly be another record breaker

[kerplunk]

Even when global av temps are smashing records it's always colder than average somwhere. Sometimes you can just look out the window but otherwise you can find out where the cold/hot anomaly is currently by looking at daily reanalysis data

 

Here's today's picture

Not happy about that blue bit stuck over us.

Global mean temps have  been quite astonishing since last year

 

Troposphere temps are likely peaking now though - the usual 3-4 month lag since peak El Nino in December.

 

How far temps will fall back in the coming year as El Nino melts away is the next interesting.

Gavin Schmidt of Nasa scratching his head:

"For the past nine months, mean land and sea surface temperatures have overshot previous records each month by up to 0.2 °C — a huge margin at the planetary scale. A general warming trend is expected because of rising greenhouse-gas emissions, but this sudden heat spike greatly exceeds predictions made by statistical climate models that rely on past observations. Many reasons for this discrepancy have been proposed but, as yet, no combination of them has been able to reconcile our theories with what has happened..

 

....If the anomaly does not stabilize by August — a reasonable expectation based on previous El Niño events — then the world will be in uncharted territory. It could imply that a warming planet is already fundamentally altering how the climate system operates, much sooner than scientists had anticipated. It could also mean that statistical inferences based on past events are less reliable than we thought, adding more uncertainty to seasonal predictions of droughts and rainfall patterns.."

As in Scotland, the targets were set to look good with no plan for achieving them. The targets will be changed because no one has prepared the voters for what is necessary.

Lots of news around this week. Some good some bad, some really bad......

Where to start.

Let's start here as it is 'just' one country:
Australia has announced it will ramp up its extraction and use of gas until "2050 and beyond", despite global calls to phase out fossil fuels.

This one is most certainly bad.....

 

Fuelled by climate change, the world's oceans have broken temperature records every single day over the past year, a BBC analysis finds.

Nearly 50 days have smashed existing highs for the time of year by the largest margin in the satellite era.

Planet-warming gases are mostly to blame, but the natural weather event El Niño has also helped warm the seas.

This one is good.................................. and with China 'leading the way' despite still opening new coal power stations which is very much not good hopefully the world will soon stop using China as a reason for inaction - but I doubt it.

 

Renewable power reaches record 30% of global electricity

Yet more growth in solar and wind last year, driven by countries like China and Brazil, marked a "milestone" in the world's switch to clean power, Ember said. There is now so much clean power that global fossil fuel power generation is about to fall, along with its emissions.

Given how their predictions have turned out to be pretty good so far this one is really bad.....

 

Hundreds of the world’s leading climate scientists expect global temperatures to rise to at least 2.5C (4.5F) above preindustrial levels this century, blasting past internationally agreed targets and causing catastrophic consequences for humanity and the planet, an exclusive Guardian survey has revealed.

Almost 80% of the respondents, all from the authoritative Intergovernmental Panel on Climate Change (IPCC), foresee at least 2.5C of global heating, while almost half anticipate at least 3C (5.4F). Only 6% thought the internationally agreed 1.5C (2.7F) limit would be met.

 

Many of the scientists envisage a “semi-dystopian” future, with famines, conflicts and mass migration, driven by heatwaves, wildfires, floods and storms of an intensity and frequency far beyond those that have already struck.

Schemes like this have huge potential to generate cheap green electricity but so far they are not part of central government plans despite there being loads of suitable mines and many are under highly populated areas.

Madder than tRump

 

As Florida copes with rising seas and record temperatures, lawmakers are going to exceptional lengths to delete many mentions of climate change from state laws in a new bill that Republican Gov. Ron DeSantis signed into law on Wednesday, according to his official X account.

The wide-ranging law makes several changes to the state’s energy policy – in some cases deleting entire sections of state law that talk about the importance of cutting planet-warming pollution. The bill would also give preferential treatment to natural gas and ban offshore wind energy, even though there are no wind farms planned off Florida’s coast.

The bill deletes the phrase ‘climate’ eight times – often in reference to reducing the impacts of global climate change through its energy policy or directing state agencies to buy ‘climate friendly’ products when they are cost-effective and available. The bill also gets rid of a requirement that state-purchased vehicles should be fuel efficient.
