Lobsters
Lobsters or Lobste.rs is a social news website mainly focused on computer engineering articles. It is based broadly on the threaded "upvote/downvote" functionality of other sites like Reddit and Hacker News. A number of the site's features are intended to prevent the site from becoming similar to other large social news aggregators: the site is invite-only, makes use of content tags, and requires a user to write an explanation each time they "downvote" a piece of content.

History
In 2012, Joshua Stein was shadow banned from Hacker News by its administrator, Paul Graham. Stein decided to build an alternative website focused on moderation transparency. Lobsters has an official transparency policy concerning moderator actions that makes all moderator actions public and prohibits shadow banning.

In October 2017, Stein retired from administrating the site. Ownership was transferred to Peter Bhat Harkins, known on Lobsters as pushcx. As of October 2019, Bhat Harkins remains the administrator of the site.

In February 2018, Lobsters helped to sponsor the lobster emoji (🦞) with the Unicode Consortium.

Invite tree
A feature distinguishing Lobsters from other news aggregator websites is that Lobsters requires users to receive an invitation before registering on the website. The website makes use of an invitation tree, where each new user is invited by an existing user, becoming a branch off of the existing user in the tree. The full invitation tree can be viewed on the website. The goal of using an invitation system is to both prevent spam and slow the rate of new users beneath the acculturation rate, preventing an Eternal September.

Hats
Hats are a feature where users who belong to a company, project, or organization may choose to wear a "hat", indicating that they are speaking on behalf of the organization. This allows users to fluidly move between commenting as just another user, to commenting in an official capacity, to commenting as themselves, without changing accounts. Specially colored red hats are worn by members of the Lobsters community that upkeep the site, marked as "Sysop".

Downvote explanations
Downvote explanations are a way of ensuring that all downvotes are accompanied by feedback that is then shown to the user receiving the downvote. The explanations are intended to discourage users from complaining about downvotes or editing their posts to ask why they were downvoted.

There are several possible justifications that can be given in a downvote explanation: "Off-topic", "Incorrect", "Me-too", "Troll", "Spam".

"Off-topic" downvotes may be given to any post or comment that is viewed by the downvoter as irrelevant to the topic at hand. "Incorrect" downvotes are given for stating information that is incorrect, and cannot be given out for matters of opinion. "Me-too" downvotes are used "when a comment signals agreement to a parent comment or submission without adding significantly to the conversation". "Troll" downvotes are used when the downvoter believes that the downvoted commenter is failing to engage in an honest dialogue, particularly when the comment is intended to provoke or aggravate another user. "Spam" downvotes are used whenever a post or comment is obvious spam.

Moderation log
Lobsters keeps a moderation log, that reports all moderation actions taken by the community or by specific moderators. The log keeps a record of any user actions that change the features of an account, such as a username change, any actions made by moderators, such as post title changes or bans, and changes made by community vote.

Category tags
Lobsters has a number of category tags, that are applied to any post that they are relevant to. This allows users to quickly sort out topics that they are especially interested in, or don't want to see, without fragmenting the community between different boards.

Infrastructure
Lobsters is hosted on a custom open-source software stack built with Ruby On Rails. Originally, Lobsters ran on top of OpenBSD, but during October 2017, it was migrated from OpenBSD to Linux during the handoff to Bhat Harkins. The code is hosted on GitHub and is licensed under a permissive license.

Noordwijk Climate conference
Noordwijk Ministerial conference on climate change

The Ministerial Conference on Atmospheric Pollution and Climate Change was the first major climate conference that took place on the 6th and 7th November of 1989 at the Grand Hotel Huis ter Duin in Noordwijk.

Attendees included ministers of

The science advisor of George H.W. Bush, D. Allan Bromley was pressured by White House Chief of Staff John Sununu to convince the other attendees to abandon the commitment to freeze emissions.

Other countries wanted to decide later at what level CO2 should be stabilized in 2000.

In 2019, the conference attracted interest due to a publication in New York Times Magazine by Nathaniel Rich, who subsequently wrote the book Losing Earth as an extension of the article.
