The Heat Was On: Atmospheric CO2 Triggered a Global Warming Event 40 Million Years AgoMike Orcutt
Deep Earth degassing is a critical forcing factor for atmospheric CO2variations and palaeoclimate changes in Earth’s history. For the Cenozoic, the key driving mechanism of atmospheric CO2variations remains controversial. Here we analyse three stages of collision-related magmatism in Tibet, which corres...
Kenya, the host of the climate summit, is one of the few countries in Africa seen as having a relatively well-developed weather service, along with South Africa and Morocco. Kenya has allocated about $12 million this year for its meteorological service, according...
This increased from 50 megatons of fertilizer per year in the early 1950s to over 300 megatons by 1990 [1]. The Haber-Bosch process to produce ammonia from atmospheric nitrogen (N) allowed for this mammoth increase in fertilizer production, but it also resulted in surplus N (NOx and NHx...
The 11 years of long-term seasonal shipboard monitoring revealed that Muskegon Lake has had at least a decade long history of mild and severe hypoxia during the summer (Fig. 7). Both types of hypoxia have been detected in at least 0–4 of the 6 sites every year since 2003. We did ...
year of 202326. It may be permanently breached as early as 2027, exhausting the entire “carbon budget” remaining to have a 50% chance to stay at 1.5°27. Moreover, evidence is mounting that current long-term climate models mayunderestimatekey parameters28: the actual rate of warming; the...
Ocean Hg0 evasion is a large source of present-day atmospheric Hg (approximately 2900 Mg/year; range 1900–4200 Mg/year). Enhanced seawater Hg0 levels suggest enhanced Hg0 ocean evasion in the intertropical convergence zone, which may be linked to high HgII deposition. Estimates of gaseous ...
