I'd normally not bother wasting time on this nonsense from @benleo444, theres simply more important work than repeatedly putting to bed zombie climate denial talking points, but in solidarity with @JustStop_Oil protesters risking their liberty, here goes🧵
@benleo444@JustStop_Oil Q1. “Why was there a warming period in the Roman times over a couple of hundred years, it was exceptionally warm and then it got cold. There wasn’t any industrial revolution?” 2/n
A. There was no global warm period in Roman times, it was a regional fluctuation due to variability in the climate system 3/n
And we also know this warming is *entirely* due to greenhouse gas emissions from human activities, primarily burning fossil fuels - oil, coal and gas 6/n
Q2. “What do you think about the international declaration signed by 1,100 climate scientists, who said that there is no climate emergency?” 7/n
A. That document is produced by a climate denial think tank with ties to the fossil fuel industry. Most of the signatories on that declaration have no expertise in climate science 🤦♂️ 8/n
Leading Earth-system scientists writing in @Nature have this to say -
“In our view, the evidence from tipping points alone suggests that we are in a state of planetary emergency: both the risk and urgency of the situation are acute” 11/n
The need for #ClimateAction is now incredibly urgent, as the @IPCC_CH latest reports tell us we have a 'rapidly closing window to secure a liveable & sustainable future for all’ 12/n
@IPCC_CH And the science is clear that means no new fossil fuels projects can go ahead! 13/n
Q3. “How much data is the recent studies based on, a coupe of hundred of years? Do you know how many years your modeling is based of?” 14/n
A. This is a pretty meaningless & vague question, but depending on the exact question you are asking we have paleo-climate data going back hundreds of thousands & even tens of millions of years.
Important context left out however, if that we have only 0.85% of the world’s total population - so we’re still using more than our share per-capita, and that’s before we take into account any of our historical emissions! 17/n
This question is an example whataboutism. A classic discourse of delay.
Movements are a crucial to achieve social change, as it is not enough to just have evidence, or even to communicate it with compelling stories, you also need to build counter-power that can force change in the existing system 3/n
We all know #climate action is incredibly urgent, the @IPCC_CH reports tell us we have a 'rapidly closing window to secure a liveable & sustainable future for all’
Scientists have been issuing such warnings for years, but it's not leading to the necessary political action 2/15
We also know that a key reason insufficient action is being taken are power structures within society, particularly the influence of vested interests seeking to maintain the status quo.
So, Jamie Dimon the CEO of @jpmorgan thinks "it is not against #climate [change] for America to boost more oil & gas".
Which could not be more wrong!
Here's a🧵on some science he (& his colleagues in the banking sector) may want to try to pass through their cranium... 1/20
@jpmorgan Firstly, #climate action is incredibly urgent, the @IPCC_CH reports tell us we have a 'rapidly closing window to secure a livable & sustainable future for all!' 2/20
It is "Now or never" if we are to have a chance of meeting the 1.5C climate target agreed at Paris.
As Prof. Jim Skea, Co-Chair of @IPCC_CH WG3 explains, we need "deep emissions reductions across all sectors". Starting NOW! 3/20
We typically talk of global average temp rise - but shifts in the mean can have big impacts on the distribution of extremes as this @NASAClimate video shows.
Here's a short🧵on what this means for future extremes... 1/n
@NASAClimate As the average temperature increases we see a corresponding shift in the extremes, so that previously rare heat extremes become common.
These extremes are temperatures to which we are not well adapted and can stress our infrastructure to breaking point. 2/n
One way to class the severity of an extreme is by statistics of the probability of occurrence.
A 2 sigma event is experienced ~2% of the time (or 2% of the surface in any year) - or on average once per 50yrs.
A 3 sigma event has 0.1% chance or 1 in every thousand years! 3/n
First things first. I was asked to participate in this debate, as I'd been arrested taking part in this protest with @ScientistsX at @beisgovuk. Our demand was simple & science led, that the UK end all NEW oil and gas exploration.
The sociological imagination can help us answer "why climate change is happening, how we are being impacted, why we have failed to successfully respond so far, and how we might be able to effectively do so." says Kari Norgaard
