COP26 will not keep temperatures below 1.5°C and maybe not 2°C

The Glasgow Climate Conference of Parties, COP26, is almost certain to fall short of its first goal to “keep 1.5°C within reach”. Moreover, even if it achieved its other aim to “secure global net-zero by mid-century” there is still a high probability that global temperatures will exceed 2°C if this isn’t matched by increased short-term action as well. That’s the message coming from climate scientists from the ARC Centre of Excellence for Climate Extremes (CLEX).

Research brief: The path to a sustainable future using marine-based mitigation measures

In this paper, as part of the Future Seas project, the researchers built upon previous work by using a foresighting scenario analysis technique to envision two alternative possible futures for society by 2030, in the context of the challenge of climate change adaptation and mitigation.

Briefing note 16: What is left in the global carbon budget?

August 25, 2021 3:37 pm Published by Comments Off on Briefing note 16: What is left in the global carbon budget?

The Paris Agreement requires countries to commit to reducing their greenhouse gas emissions to ensure that the global average temperature remains well below 2°C above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5°C. But how likely are we to meet these targets?

Briefing note 15: Can we limit global warming to 1.5C°?

July 28, 2021 2:43 pm Published by Comments Off on Briefing note 15: Can we limit global warming to 1.5C°?

Irrespective of tipping points, climate change adaptation efforts will be less costly and disruptive to society – and will stand a better chance of success – if warming can be limited to 1.5°C rather than 2°C or higher. We therefore in no way advocate for policies that forgo pursuing the ambition to limit global warming to 1.5°C, regardless of whether that target remains feasible or not.

Research brief: If dimethyl sulfide emissions ceased, Earth would warm 0.5C in a decade

August 15, 2018 12:12 pm Published by Comments Off on Research brief: If dimethyl sulfide emissions ceased, Earth would warm 0.5C in a decade

The study finds important regional consequences for precipitation and clouds formation if large changes in dimethyl-sulfide emissions were to occur.  In a hypothetical case where all marine DMS emissions cease completely, we find the Earth would warm by approximately 0.5 degrees C over a ten-year period.
