btw I often manage to find full versions of papers without an institution login by searching on the paper's title

That's certainly not light reading! Interesting though,

 

"This study underscores the need for a coordinated
stewardship of the northern land sink as part of the climate policy
agenda, with the objective to maintain land sinks through favourable
land use and enhance them whenever possible."

 

So maybe FH is wrong, and we do need to concentrate up north, or do both. It's certainly not as clear cut as it may appear, who knew this stuff was so complicated! If climate change over the past few decades is part of the driver of the shift in the sinks how does that factor in? if the North gets warmer and the carbon sink increases maybe that will help offset the warming and we will reach an equilibrium. (here's hoping).

we need to exterminate all humans.

Wouldn't that release carbon?

This link concludes its better overall to preserve exisitng forests even though new trees absorn more carbon.

Make that - we need to fatten up all humans

this could have big implications....

 

might take the govt to court for this sh*tty weather ruining my spring.

Wow, that's a crazy judgement, Switzerland is a tiny country, global warming is, well, global, even if Switzerland had implemented all these measures sooner it would have made no difference to the weather in Switzerland. Totally political judgement, no logic to it.

Only two years...sh*t man, better make the most of it.

The whole interview is worth watching. There's more than just bashing the Tories

[steviewevie]

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

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.."
