Terrer, C.; et al. (2019): Nitrogen and phosphorus constrain the CO 2 fertilization of global plant biomass

Terrer, César; Jackson, Robert B.; Prentice, I. Colin; Keenan, Trevor F.; Kaiser, Christina; Vicca, Sara et al. (2019): Nitrogen and phosphorus constrain the CO 2 fertilization of global plant biomass. In Nat. Clim. Chang. 9 (9), pp. 684–689. DOI: 10.1038/s41558-019-0545-2.

"The global-scale response to eCO2 we derive from experiments is similar to past changes in greenness9 and biomass10with rising CO2, suggesting that CO2 will continue to stimulate plant biomass in the future despite the constraining effect of soil nutrients. Our research reconciles conflicting evidence on CO2 fertilization across scales and provides an empirical estimate of the biomass sensitivity to eCO2 that may help to constrain climate projections."

EPA: EPA Proposes Updates to Air Regulations for Oil and Gas to Remove Redundant Requirements and Reduce Burden

"The U.S. Environmental Protection Agency (EPA) proposed updates to the prior administration’s national standards for the oil and natural gas industry. The proposal would remove regulatory duplication and save the industry millions of dollars in compliance costs each year – while maintaining health and environmental regulations on oil and gas sources that the agency considers appropriate."

Report Launch Event: How to Talk About Carbon Removal: Critical Questions About Climate Change Futures

12. September 2019, Washington D.C. / US

"Join Northeastern University professor Matthew Nisbet and the Institute for Carbon Removal Law & Policy for a discussion on a report in preparation, The Carbon Removal Debate: Asking Critical Questions about Climate Change Futures. The report works towards a common climate justice framework that can inform how various stakeholders think about, talk about, and act on this potentially transformative—but as yet still unproven—technology."

Pierrehumbert, R. (2019): There is no Plan B for dealing with the climate crisis

Pierrehumbert, Raymond (2019): There is no Plan B for dealing with the climate crisis. In Bulletin of the Atomic Scientists 75 (5), pp. 215–221. DOI: 10.1080/00963402.2019.1654255.

"When first suggested, such albedo modification schemes were introduced as a “Plan B,” in case the world economy fails to decarbonize, and this scenario has dominated much of the public perception of albedo modification as a savior waiting in the wings to protect the world against massive climate change arising from a failure to decarbonize."

Scheffran, J. (2019): The entwined Cold War roots of missile defense and climate geoengineering

Scheffran, Jürgen (2019): The entwined Cold War roots of missile defense and climate geoengineering. In Bulletin of the Atomic Scientists 75 (5), pp. 222–228. DOI: 10.1080/00963402.2019.1654256.

"The first approach to the nuclear and climate threat focuses on arms control, non-proliferation and disarmament and on greenhouse gas emission reductions and mitigation. The second approach involves active defense: in the nuclear realm, missile defenses against nuclear-armed delivery systems; for climate change, geoengineering that removes carbon dioxide from the atmosphere or changes the Earth’s radiation balance."
