“…According to Blasing (Blasing, 2010(Blasing, , 2016Forster et al, 2007), the increase in the GHG CH 4 since 1750 has induced a radiative forcing of about +0.5 W m −2 . The research results of Wittmer et al (2015aWittmer et al ( , b, 2016 Zetzsch (2016) demonstrated the possibility of significantly reducing the CH 4 lifetime by the ISA method significantly.…”

Abstract. Power stations, ships and air traffic are among the most potent greenhouse gas emitters and are primarily responsible for global warming. Iron salt aerosols (ISAs), composed partly of iron and chloride, exert a cooling effect on climate in several ways. This article aims firstly to examine all direct and indirect natural climate cooling mechanisms driven by ISA tropospheric aerosol particles, showing their cooperation and interaction within the different environmental compartments. Secondly, it looks at a proposal to enhance the cooling effects of ISA in order to reach the optimistic target of the Paris climate agreement to limit the global temperature increase between 1.5 and 2 • C.Mineral dust played an important role during the glacial periods; by using mineral dust as a natural analogue tool and by mimicking the same method used in nature, the proposed ISA method might be able to reduce and stop climate warming. The first estimations made in this article show that by doubling the current natural iron emissions by ISA into the troposphere, i.e., by about 0.3 Tg Fe yr −1 , artificial ISA would enable the prevention or even reversal of global warming. The ISA method proposed integrates technical and economically feasible tools.

“…Gulf (1973Gulf ( -2012 The increase of carbon dioxide (from 280 to 390 ppm; Blasing, 2013) and other greenhouse gases due to the burning of fossil fuels since the industrial revolution (1750) has led to a pronounced increase in global temperature (Preining, 1992) of 0.4-0.8 ∘ C during the past century (EPA, 2012). Our analysis suggests that the temperature in the N Gulf has increased by 0.8 ∘ C just in the past 40 years and may continue to increase at a rate of 0.02 ∘ C year -1 (0.01, 0.04) if we assume a similar trend of increase in air temperature (Figure 4(a)).…”

This paper presents key results from analysis of surface meteorological observations collected in the Northern Arabian/Persian Gulf (N Gulf; Kuwait, Bahrain, and NE Saudi Arabia), which spans a 40-years period . The first part of this study analyzes climate variability in the N Gulf, and relates them to teleconnection patterns (North Atlantic Oscillation, El Nino Southern Oscillation, and Indian Ocean Dipole). Results of the analysis indicate that during the study period the climate in the region experienced a general trend of increase in temperature (0.8 ∘ C), decrease in barometric pressure (1 mbar), reduction in humidity (6%), and decrease in visibility (9%). Significant correlations were found between the three teleconnection patterns and the meteorological conditions suggesting that seasonal variabilities in air temperature, barometric pressure, and precipitation are closely related to the teleconnection patterns. The second part of this study examines the 40-year variability of Shamal events (strong NW winds that commonly generate significant dust storms). The data suggests that on average Shamal events occur at a rate of 10 events year -1 with 85% of the events occurring during the summer and winter. The number of these events has increased in the past 14 years of the study period. These events resulted in abrupt changes in meteorological conditions: an increase in wind speed of 2.7 m s -1 , a decrease in visibility of 1.7 km, and reduction in humidity of 4.3%. Seasonal variations in temperature (an increase in temperature during summer of 0.8 ∘ C, and a decrease of 1.5 ∘ C during winter) and barometric pressure (a decrease in barometric pressure during summer of 0.6 mbar and an increase of 7.8 mbar during winter) were observed during Shamal events.
