A thread about #whales🐳 in the latest @IPCC_CH report on climate.
1) We are already seeing, with a high level of confidence, reproductive failures and declining abundances due to warmer polar oceans and reduced sea ice.
2) North Atlantic Right and Gray whales are the two most vulnerable marine mammal species, both of whom are already critically endangered. #NARW
3) The extinction of the these #whale species (and reduction in others) will disproportionately eliminate unique and important evolutionary lineages as well as functional diversity, with consequent impacts THROUGHOUT THE ENTIRE MARINE ECOSYSTEM.

Yo les kheys ! Apparemment c'est la saison des tops, donc à moi de vous proposer le mien. Voici les 13 #Crypto sur lesquelles je vais compter en 2022 avec mes réflexions perso et triées en 4 catégories de risque. Let's go 🧵

Avant de commencer, je rappelle quelques règles basiques 👇

✅ Ce n'est pas parce que je mise sur ces tokens que vous devez en faire de même, faites vos devoirs !

✅ Je peux parfaitement me planter, certains tokens peuvent partir au placard, donc gestion du risque !

✅ Inutile de venir me chercher parce que votre token favori est absent, c'est mon wallet et il ne bougera pas sauf quand je l'aurai décidé.

✅ Mes choix sont faits après des analyses techniques et fondamentales. Je ferai au mieux pour détailler ma démarche.

Yo les kheys ! Nous y voilà, dernier jour d'une année 2021 qui aura été exceptionnelle à tous les niveaux. Je profite de cette occasion pour vous proposer mon bilan de l'année, mes échecs, mes réussites et mes objectifs pour 2022. Let's go 🧵
Pour ceux qui ne le savent pas, je suis arrivé relativement tard sur le marché crypto (fin Janvier 2021). Avant cela, j'étais surtout sur de l'investissement traditionnel (ETFs et assurance vie notamment) comme tout boomer qui se respecte (j'aurai 30 ans en Janvier).
J'avais déjà quelques connaissances sur la technologie de la blockchain, ayant rapidement travaillé sur le sujet lorsque j'étais chez Ubisoft, mais je ne m'étais jamais intéressé à l'aspect spéculatif de la chose.

The 24 Gurus in our life....a #Thread

In general, humans work hard to nurture religion, economic progress, sense satisfaction, and spiritual knowledge, with the goal of extending their lives, gaining reputation, and enjoying material riches.

#Web3 Nedir?
'İnternet Kültüründe bir değişimdir! Tek cümle ile internetin bir sonra ki çağı. Web3, demokratikleştirilmiş ve Merkeziyetsizleştirilmiş bir İnternete doğru bir paradigma kaymasıdır'

Web3 hizmet eden Projeler⬇️
1-)Web3 teknolojisini algılayabilmek için öncelikle daha önceki sürümleri Web-1 sonrasında Web-2 teknolojilerini hakim olmak gerekir.
2-)Web-1 İnternetin ilk aşaması ve kullanıcıların başlangıçta web ile etkileşime girme şekli ile karakterize edilebilir. Web 1.0’da çoğu kullanıcı, içeriğin pasif tüketicileriydi. Bir başka deyişle, Web 1.0 yazmakla değil; okumakla ilgiliydi. Dinamik değil, statikti.

Models project that #ocean #phytoplankton will become increasingly starved of #nitrogen as #climatechange progresses.

If realised, this has implications for #fisheries.

But how can we monitor this change in the real ocean?

Nitrogen isotopes!
What are nitrogen (N) isotopes?

There is a heavy isotope (15-N) and a light isotope (14-N).

Some processes prefer to use 14-N more than 15-N. When phytoplankton use nitrogen, they prefer 14-N.

This increases the ratio of 15-N to 14-N in seawater.
But when N is scarce, phytoplankton have less preference.

Like if there was only one kind of pizza at a party, you don't have the option of being picky (you have to have the pineapple).

In this case, phytoplankton no longer increase the ratio of 15-N to 14-N in seawater.

This tiny crab trapped in 100-million-year-old amber is the most complete fossil crab ever discovered! But how did a crab get trapped in amber in the first place? Here we tell you the story… #Science #Evolution #SciComm 1/n Image
Transitions from marine to non-marine environments (e.g., land, brackish & freshwater) are an infrequent even in most animal groups. And yet, true crabs, or #Brachyura, have done it independently over a dozen times! #ocean #freshwater #evolution 2/n Mangrove tree crab, Aratus ...
Amber is like a time capsule that preserves organisms like frozen in time. While most fossils in amber are land-dwelling animals—principally insects—, aquatic organisms such as crabs are extremely rare! #amber #jurassicpark #Cretaceous #Crabs Photo by @LidaXing1982 3/n Image

1. Both predators and prey animals use camouflage to their advantage.

Prey animals blend in with the background, so hungry predators pass right by them.

🧵 Start of a thread with some amazing videos on #Camouflage.

I like this one. 🙂

#cats #pets

2. But predators use camouflage too.

The striated frogfish (Antennarius striatus) walks the seafloor right up to its unsuspecting prey.

It has a prognathous mouth that launches an attack on prey in as fast as 6 milliseconds.

Hi everyone, I’m Dr. Boisvert! Today I want to talk to you about the parts of the #ocean that freeze over, like this sea ice just outside of Thule, Greenland in the Arctic taken during an Operation #IceBridge campaign in 2016. 🧊🧊🧊🧊#WorldOceansDay
The seas in the mid-Atlantic and the Arctic are very different, but they’re part of the same global ocean! Here’s me ‘floating’ on sea ice off the coast of Greenland in 2016 and me again floating on Ocean City Beach in Maryland last weekend. 🧊🧊🧊🌊🌊🌊#WorldOceansDay
In the Arctic the ocean is cold enough (-1.8ºC🥶) to freeze saltwater and create sea ice. But here in the mid-Atlantic, the ocean is much warmer thanks to a massive current known as the Gulf Stream, which transports heat from the tropics.🌴🌎🌴 #WorldOceansDay

#Whales & #dolphins are facing many manmade existential threats: depletion of food by overfishing, drop in birthrates due to industrial pollution, killing by discarded fishnets & plastics etc
#Watch #Seaspiracy. It’s #seas #piracy. It’s #conspirasea
Over 300,000 #whales and #dolphins are killed as bycatch in #fishnets every year. People eating #seafood is the reason that fishing trawlers go to sea & cause these deaths of whales & dolphins. #Boycott #seafood. It’s #seas #piracy

Every year at least 50 million #sharks are killed as #bycatch in commercial #fishing. 90% of sharks have been lost in the last few decades. Eating seafood contributes to the bykill of sharks and other #sealife.

A thread (Part 1)

The Law of the Lord Is Perfect (Ps. 19:1-5 ESV)

To the choirmaster. A Psalm of David.
The heavens declare the glory of God,
and the sky above proclaims his handiwork.
Day to day pours out speech,
and night to night reveals knowledge.
There is no speech, nor are there words,
whose voice is not heard.
Their voice goes out through all the earth,
and their words to the end of the world.
In them he has set a tent for the sun,
which comes out like a bridegroom leaving his chamber,

In the #LongFoodMovement report, we're reminded that the world’s 30 million artisanal #fishers and workers provide nearly half of the #fish we eat (@IPBES, 2019).

But with #climatechange & island/ocean grabbing, small-scale fishers & their communities are in peril.

🧵Thread 👇🏾
Island/#ocean grabbing is likely to intensify as countries seek to solidify their influence, their #food supply chains, & their global sourcing and distribution networks. For example, in the #RedSea region, conflicts over fish & other marine resources threaten rich #biodiversity.
Meanwhile, in the South China Sea, said to
