++ THREAD ++

On Monday, the #IPCC published its 6th #ClimateReport.

Carbon Brief pored over more than 3,000 pages to produce this in-depth Q&A.

It unpacks the key findings of the report and explains the developments since the previous assessment.
Headlines 📰 this week from around the world have focused on the report’s main findings.

“Starkest warning yet”
“Code red for humanity”

@Josh_Gabbatiss @AyeshaTandon & @GAViglione pulled together the key reactions from newspapers in an interactive table

When is the world 🌎 expected to pass 1.5C and 2C of warming?

@hausfath explores the updated estimates here ⬇️

One of the key developments is the link between human-caused warming and increasingly severe #ExtremeWeather, which is now “an established fact”.

@rtmcswee unpicks what the reports says about:

🔥 Heat
☔️ Rainfall
🌊 Flooding
🌵 Drought
🌀 Cyclones

AR6 pulls together the findings from more than 14,000 peer-reviewed studies.

Carbon Brief spoke to 16 #climate scientists, many of whom were co-authors on the report, to ask them to pick out the most important insights.

@rtmcswee has compiled the key statements from the ‘Summary For Policymakers’ and compared them to the IPCC’s previous assessment and recent special reports. Image

NEW | Limiting warming to 1.5C would ‘halve’ land-ice contribution to sea level rise by 2100 | @ayeshatandon j.mp/3ePH0AM

NEW | Guest post: Overshooting 2C risks rapid and unstoppable sea level rise from Antarctica j.mp/3ejoK3C

(1/7)
Today, we bring you coverage of two @nature papers.

1. Projects 25cm of sea level rise from land ice melt by 2100 under current emission pledges.

2. Projects greater mass loss from Antarctica, warning of an “abrupt jump” in Antarctic ice melt if warming exceeds 2C.

(2/7)
The first study brings together 84 authors from 62 institutions.

The authors look at six scenarios for 21st century temperature rise.

Limiting warming to 1.5C instead of following current pledges could halve the sea level rise from melting land half ice, they find.

As 2020 draws to a close, here is a taster of the range of content and topics that Carbon Brief has covered over the past 12 months… 🗓️

THREAD
The year has been dominated, of course, by Covid-19. In April, @DrSimEvans estimated that widespread lockdowns could knock 5.5% off global CO2 emissions in 2020: bit.ly/3axKirQ

📉 This month, @gcarbonproject said it will likely clock in at 7%: bit.ly/3h7Sznz
📈 But analysis we published in May explained that levels of CO2 in the atmosphere will still rise this year ➡️ bit.ly/3pfC77s

And @Josh_Gabbatiss covered a study showing the dip in emissions would only prevent around 0.01C of warming ➡️

NEW | Interactive: What is the climate impact of eating meat and dairy? @daisydunnesci @tomoprater @joegoodman94

This is the first article in Carbon Brief’s week-long series on food and climate change…

j.mp/2Fx9vFu

THREAD 1/7
It explores the science of how eating animal products drives emissions…

2/7
Emissions from beef production vary across different farms and countries. This chart shows the spread of emissions produced in the making of various foods.

While meat causes the highest emissions, the production of some foods, including certain nuts, can help to reduce CO2.

Several #Arctic locations recorded land surface temperatures hitting 45C on 19 June, according to initial data from the @esa satellite Sentinel-3.

Here is what you need to know... (THREAD 1/7)
Also widely reported is a potential new Arctic temperature record of 38C in Verkhoyansk – a town in #Siberia, Russia – on 20 June

See @CarbonBrief’s Daily Briefing: carbonbrief.org/daily-brief/uk…

So why is 38C potentially a new record, but not 45C?

2/7
The 45C reading is land surface temp – how hot the surface is to the touch – which is commonly measured by satellites.

The 38C reading is surface air temp – how warm the air is just above the ground. This is what is you usually see in weather forecasts and climate data.

+++BREAKING+++

Great Britain has been running for a record TWO WEEKS without using coal to generate electricity – the first time this has happened since 1882.

The country’s grid has been coal-free for 45% of hours in 2019 so far.

carbonbrief.org/countdown-to-2…
Great Britain has already been running for 1,637 hours without coal in 2019, the equivalent of 68 days out of 150.
During the two-week run without coal, Great Britain has been powered by:

41% gas
21% nuclear
12% wind
11% imports
8% biomass
7% solar

Great Britain has just gone a whole week without using coal to generate electricity | @drsimevans @tomoprater bit.ly/304amDj
@DrSimEvans @tomoprater In 2019 to date, Great Britain has had 1,139 hours without coal-fired electricity.

That's the equivalent of 47 days – or one third of all hours in the year so far.
@DrSimEvans @tomoprater The amount of electricity generated from coal is down 90% in five years.

Coal now supplies less than 5% of the electricity generated in the UK.

It was 40% as recently as 2012.
