Simon Donner (Associate professor of climatology at the University of British Columbia) has asked this important question: Can Canada reconcile its climate policy and the temperature targets in the Paris agreement?
In NATURE GEOSCIENCE, Kevin Anderson (Tyndall Centre for Climate Change Research, University of Manchester) has estimated that cement, deforestation and energy are the major sources of carbon emission. He has calculated that the remaining carbon budget for energy-only emissions over the period 2015–2100, for a ‘likely’ chance of staying below 2 °C, is about 650 Gt of CO2. This represents approximately 65% of the original carbon budget of 1,000 GtCO2.
Kevin Anderson writes that "To avoid exceeding 650 Gt, global mitigation rates must rapidly ratchet up to around 10% per year by 2025, continuing at such a rate towards the virtual elimination of CO2 from the energy system by 2050." That is to achieve a 66% chance of staying below 2 °C which most scientist have stated will inflict significant damage.
We have included a number of YouTube videos of Kevin Anderson in the Media section.
According to Richard Heede, "a total of 914 billion tonnes of CO2-equivalent (GtCO2e) has been traced to 90 international entities based on analysis of historic production records dating from 1854 to 2010."
Heede’s analysis, states that half of the estimated emissions from the 90 firms studied was released in the past 25 years – past the date when most companies would have been aware that their emissions were affecting the environment.
