Global fossil CO₂ emissions set to grow a slow 0.6% in 2019 [range: -0.2% to +1.5%] with robust growth in oil & natural gas, but a slight decline in coal.

1/
We project global coal, oil, & gas emissions for 2019
* Natural gas up 2.6% [+1.3% to +3.9%], driving >50% of growth since 2012
* Oil up 0.9% [+1.3% to +3.9%] continuing trends
* Coal down -0.9% [-2.0% to +0.2%] continuing its woes

2/
By region
* China +2.6% [+0.7% to +4.4%], GDP vs stimulus
* USA -1.7% [-3.7% to +0.3%], coal -10%
* EU28 -1.7% [-3.4% to +0.1%], coal -10%
* India +1.8% [+0.7% to +3.7%], big monsoon, weak economy
* Others +0.5% [-0.8% to +1.8%], weak economy

Thread: Blatant #ClimateDenial has lost. The new conflict is whether #ClimateChange is a crisis requiring urgent social and #economic transformation, or something we can adapt to incrementally while carrying on with business as usual. 1/40
2/ A recent opinion piece by Bjorn Lomborg in the @globeandmail is representative of the 'business as usual argument'. Let's deconstruct it to see how this gets passed off as the pragmatic point of view, and why it's false. theglobeandmail.com/opinion/articl…
3/ The basic tactic is this: provide a few common-sense truths to gain the air of pragmatism and then feed us the story we're desperate to hear: that everything will be fine, that growth will outpace #ClimateDamages and life can carry on as usual.

THREAD: In a new study in @nature we present a way to avoid the bias that burdens future generations and the risky strategies that current #climate change mitigation pathways suffer from.

A #climatetwitter explainer

Existing #ClimateChange scenarios focus on reaching a target in 2100

but by doing so weirdly suggest that the best way to achieve a #climate target is to delay action first, miss it over the next decades, and then to try to make up for it later

(2/n)
This puts put a disproportionate burden on future generations, who:
-will suffer higher #climate impacts in their lives
-are burdened with later cleaning up the mess by actively pulling #CO2 out of the air

This strategy is very risky and can be avoided

THREAD (Global Fossil CO₂ Emissions)

Global fossil CO₂ emissions are on track to rise more than 2% in 2018 (2.7%, range 1.8% to 3.7%). Emissions rose 1.6% in 2017 (leap-year adjusted) after a temporary slowdown from 2014 to 2016.

#CarbonBudget #COP24 globalcarbonproject.org/carbonbudget/i…
Countries that need to slowdown:
* China, up 4.7% [2.0–7.4%]
* India, up 6.3% [4.3–8.3%]
* Others (largely developing), up 1.8% [0.5–3.0%]

Countries that need faster reductions:
* USA, up 2.5% [0.5–4.5%]
* EU, down 0.7% [-2.6–1.3%]

#CarbonBudget #COP24 globalcarbonproject.org/carbonbudget/i…
There is a broad spread in CO₂ emissions per capita, but for a chance of 1.5°C or 2°C, countries with low per capita emissions also have to reduce emissions.

Yes, developed countries have to do more, but they can’t do it alone!

Steeling myself with a strong coffee to sit down and read major new report on avoiding dangerous #climatechange (@IPCC_CH #SR15, available here: ipcc.ch/report/sr15/). My takes to follow (1/n)
As always, the #peerreview effort by @IPCC_CH is Herculean. A couple hundred volunteer scientists read & cited 6,000+ studies to support conclusions w/ evidence. Responded to 42,001 comments in 3 rounds of review. The most robust process there is to establish scientific consensus
Now, this #SR15 report title is descriptive, but doesn't exactly roll off the tongue...
