These headlines on the latest @WWF@ZSLScience Living Planet Index are completely wrong and misrepresent the reports findings.
Here's a short thread on what the report actually show🧵
Before I begin, let me be completely clear: The destruction of nature is a massive threat, equal to that of the climate crisis.
It is vital that we reverse the losses to biodiversity, & that will require systems wide transformation to our economies! 2/n theguardian.com/commentisfree/…
The @LPI_Science is is a measure of the state of the world's #biodiversity based on population trends of monitored vertebrate species globally.
The index shows a staggering and alarming decline since 1970 3/n
@LPI_Science It is important to understand that the index is a composite that shows the *average* decline in sub-populations of the species that are being monitored.
"the number of species which have positive and negative trends are more or less equal, this means that the magnitude of the declining trends exceeds that of the increasing trends in order to result in an average decline for the global LPI."
This is also what we see at the population level...
So you can see that claims that "70% of animal populations have been wiped out" or that "we have wiped out 70% of animals" are not at all accurate interpretations of this index shows us 7/n
The continued decline of the index is bleak news, but if we know that many populations are increasing we can learn what works from that.
Given the continued #AttackOnNature I believe we need to go much further; its not just protecting the environment & conserving species, ultimately its about our survival on this planet!
In light of their decision to invite two notorious climate deniers to speak at their conference, I have decided I must withdraw from participating in the CC Forum "Investment in Sustainable Development" event in London next week london.cc-forum.com
🧵1/8
Given the immense stakes & need for immediate climate action, I cannot in good conscience lend legitimacy to an event that would profile grifters who knowingly shill for fossil fuel polluters, even as millions have their lives & livelihoods destroyed by climate impacts 2/8
I was initially excited to speak at the event, billing itself as a “conference which is 100% dedicated to investment in sustainability”. But was horrified to subsequently discover Monckton & Morano added to the agenda. Both are infamous for spreading climate disinformation 3/8
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
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
