| A study estimates that "relocating current croplands to [environmentally] optimal locations, whilst allowing ecosystems in then-abandoned areas to regenerate, could simultaneously decrease the current carbon, biodiversity, and irrigation water footprint of global crop production by 71%, 87%, and 100%", with relocation only within national borders also having substantial potential.[{{cite news |title=Relocating farmland could turn back clock twenty years on carbon emissions, say scientists |url=https://phys.org/news/2022-03-relocating-farmland-clock-twenty-years.html |access-date=18 April 2022 |work=University of Cambridge |language=en}}][{{cite journal |last1=Beyer |first1=Robert M. |last2=Hua |first2=Fangyuan |last3=Martin |first3=Philip A. |last4=Manica |first4=Andrea |last5=Rademacher |first5=Tim |title=Relocating croplands could drastically reduce the environmental impacts of global food production |journal=Communications Earth & Environment |date=10 March 2022 |volume=3 |issue=1 |page=49 |doi=10.1038/s43247-022-00360-6 |bibcode=2022ComEE...3...49B |s2cid=247322845 |language=en |issn=2662-4435|doi-access=free |hdl=10810/61603 |hdl-access=free }}]

| Analysis, Observation
| Researchers report that over 80% of the growth of methane emissions during 2010–2019 was caused by tropical terrestrial emissions.[{{cite news |title=Tropical methane emissions contribute greatly to recent changes in global atmospheric methane growth rate |url=https://phys.org/news/2022-03-tropical-methane-emissions-contribute-greatly.html |access-date=19 April 2022 |work=Chinese Academy of Sciences |language=en}}][{{cite journal |last1=Feng |first1=Liang |last2=Palmer |first2=Paul I. |last3=Zhu |first3=Sihong |last4=Parker |first4=Robert J. |last5=Liu |first5=Yi |title=Tropical methane emissions explain large fraction of recent changes in global atmospheric methane growth rate |journal=Nature Communications |date=16 March 2022 |volume=13 |issue=1 |pages=1378 |doi=10.1038/s41467-022-28989-z |pmid=35297408 |pmc=8927109 |bibcode=2022NatCo..13.1378F |language=en |issn=2041-1723}}]

| Depletion of ozone in the stratosphere and, more importantly (60%), ozone increase in the troposphere is shown to be responsible for ~30% of upper Southern Ocean interior warming between 1955 and 2000.[{{cite news |title=Ozone may be heating the planet more than we realize |url=https://phys.org/news/2022-03-ozone-planet.html |access-date=19 April 2022 |work=University of Reading |language=en}}][{{cite journal |last1=Liu |first1=Wei |last2=Hegglin |first2=Michaela I. |last3=Checa-Garcia |first3=Ramiro |last4=Li |first4=Shouwei |last5=Gillett |first5=Nathan P. |last6=Lyu |first6=Kewei |last7=Zhang |first7=Xuebin |last8=Swart |first8=Neil C. |title=Stratospheric ozone depletion and tropospheric ozone increases drive Southern Ocean interior warming |journal=Nature Climate Change |date=April 2022 |volume=12 |issue=4 |pages=365–372 |doi=10.1038/s41558-022-01320-w |bibcode=2022NatCC..12..365L |s2cid=247844868 |url=https://www.researchgate.net/publication/359643522 |language=en |issn=1758-6798|url-access=subscription}}]
