A collection of state government representatives and environmental groups criticised the US Environmental Protection Agency's (EPA) proposed Affordable Clean Energy (ACE) rule at its lone public hearing on Monday, saying the regulation would backtrack on climate change mitigation in the power sector and be a detriment to public health.

Today, many Australian urbanites see rivers as little more than picturesque places for a paddle. But in the colonial era, rivers served as highways, drinking sources, sewers, and routes to discovery.

As a wealthy, warm country, the US would benefit from implementing a carbon tax to slow global warming

The social cost of carbon is a measure of the economic damages caused (via climate change) by each ton of carbon pollution that we produce today.  It’s difficult to estimate because of physical, economic, and ethical uncertainties.  For example, it’s difficult to predict exactly when various climate tipping points will be triggered, how much their damages will cost, and there’s also a question about how much we value the welfare of future generations (which is incorporated in the choice of ‘discount rate’).

In 2013, the Obama administration set the federal social cost of carbon estimate at $37 per ton of carbon dioxide (up from the previous estimate of $22).  That was a conservative estimate – in recent years, research has pegged the value closer to $200 because recent research has shown that global warming slows economic growth, which makes it quite expensive.  A majority of economists in a 2015 survey believed the federal estimate was too low, but Republicans have recently been trying to dramatically lower it anyway.

PM says he and Mathias Cormann were responsible for awarding the money to foundation in one year

Scott Morrison has said he and the finance minister, Mathias Cormann, were responsible for the government’s decision to give $444m to the Great Barrier Reef Foundation in one year.

At a doorstop in Perth on Monday the prime minister said that the pair, as the Coalition’s economic team before the 2018 budget, had worked out “the best way to do [the grant] financially”, and argued it was the right decision because it helped the reef without “blowing the budget”.
