Newcastle residents celebrate ParisAgreement entry into force forming a 2100 sealevelrise high tide mark

On November 4, residents of Newcastle in the Hunter region of New South Wales celebrated the entry into force of the Paris Agreement. Hundreds of people woke up early and formed a high water tide mark line to indicate where sea level rise may reach by 2100.

"Hundreds of people have come together in Newcastle this morning in response to the governments failure to ratify the Paris Climate Agreement, which comes into force today. The group formed a blue line signifying the predicted high tide for Newcastle in 2100 and are calling on the federal government to ratify the agreement and start phasing out fossil fuels as a matter of urgency." said the group in a Facebook posting by the Hunter Community Environment Centre.

The Paris climate agreement set a “safe” global warming limit of below 2℃, aiming below 1.5℃ by 2100. The world has already warmed about a degree since the Industrial Revolution, and on our current emissions trajectory we will likely breach these limits within decades.

However, we could still come back from the brink with a massive effort.
