The Prisoner's Dilemma in Real Life

The Prisoner's Dilemma is a game theory scenario created by Merrill Flood and Melvin Dresher in 1950. Two criminals are imprisoned in isolation and taken to court. There is only enough evidence to convict them on a 1 year charge, however they both have evidence that will result in greater charges. If they both remain silent, they both serve 1 year in prison. If they both betray eachother, they both serve 2 years in prison.

Ireland #2 Good Country

Ireland has been ranked number two on the Good Country index, which collates what a country contributes to global society and what it takes away relative to its size. While we rank highly for International Peace & Security (4th), Prosperity & Equality (6th) and Culture (9th) contributions, our Planet & Climate (27th) and Science & Technology (46th) contributions need work.

Immediate Fossil Fuel Phaseout Needed

A study from the University of Leeds says that there is a 66% chance of keeping temperature increase below a 1.5 degree increase if a fossil fuel phaseout begins immediately. The research assumes a lifespan for powerplants of 40 years, cars 15 years and planes 26 years. It also assumes a rapid end to beef and dairy consumption. If the phaseout doesn't being until 2030, the chances reduce to 33%.

Book Review: 21 Lessons for the 21st Century - Yuval Noah Harari

Yuval Noah Harari's third book 21 Lessons for the 21st Century is an interesting look at 21 topics where we humans can improve. The lessons are grouped into 5 categories; The Technology Challenge, The Political Challenge, Despair and Hope, Truth, and Resilience. The subject matter for the first part of the book is tough reading. Harari takes a cold and calculating look at the societal organisations and structures that humans have created, from religion all the way up to modern day terrorism, before looking at how the species can be resilient in the face of these challenges.

Ireland Underwater in 80 years

Environmental write John Gibbons was interviewed by Mario Rosenstock on TodayFM this week about climate change. The 11 minute interview is worth listening to and includes some hard hitting scenarios about how bad the effects of climate change could be, depending on whether we act now or not. The above illustration shows the devastating effect a 3m+ rise in sea levels would have on Ireland.

Tá / Yes

On a positive note, among the many wonderful things that happened in 2018, one of my favourite was when 66.4% of Ireland voted to repeal the 8th amendment to the constitution on May 26, 2018, and has since been passed into law. I could not have been more proud to be Irish this year.
