Tremendous energy cascading through powerful earth sub-systems terra et aqua table d gaskets

To understand the multiply coupled Earth system requires tracing the flow of energy through the relevant physical mechanisms. Over decadal to millennial scales much climate variability emerges from polar regions in changing patterns of meridional (north/south) and zonal (east/west) wind fields that are related to polar surface pressure. gas vs diesel cars Process level models suggest that it is the result in part of solar UV/ozone chemistry in the upper atmosphere translating through atmospheric pathways into surface pressure changes at the poles ( Ineson et al 2015). Observations suggest that more meridional patterns are associated with low solar activity ( Lockwood et al 2010). 1 electricity unit is equal to how many kwh There is a further more speculative suggestion that the 20 to 30 year periodicity of the Earth system is caused by the ~22 year Hale cycle of solar magnetic reversal. The next climate shift is due in the next decade if it is not happening now. electricity schoolhouse rock With a dimming sun – it may be to a yet cooler state in both hemispheres.

Multi-decadal variability in the Pacific is defined as the Interdecadal Pacific Oscillation (e.g. Folland et al,2002, Meinke et al, 2005, Parker et al, 2007, Power et al, 1999) – a proliferation of oscillations it seems. gas bubble retinal detachment The latest Pacific Ocean climate shift in 1998/2001 is linked to increased flow in the north ( Di Lorenzo et al, 2008) and the south (Roemmich et al, 2007, Qiu, Bo et al 2006)Pacific Ocean gyres. Roemmich et al (2007) suggest that mid-latitude gyres in all of the oceans are influenced by decadal variability in the Southern and Northern Annular Modes (SAM and NAM respectively) as wind driven currents in baroclinic oceans ( Sverdrup, 1947). The Pacific state shifts abruptly in 20 to 30 year regimes that sum to millennial variability.

Increased flow in the Peruvian and Californian Currents lead to enhanced cold and nutrient rich upwelling on the eastern margin of the Pacific – and feedbacks across the Pacific in wind, currents and cloud that have global impacts on climate, hydrology and biology. cheapest gas in texas Cloud convection cells persist for longer over cool ocean surfaces than warmer before raining out from the center to let in the sun ( Koren et al 2017). gas quality Satellite and surface observation suggest that this was the dominant source of warming in the last decades of the 20th century ( Clement et al 2009).

In a practical sense whatever science says makes no difference to rational responses to either intrinsic climate variability or greenhouse gas emissions – which is to build prosperous and resilient communities. Technological innovation exponentially accelerates and a fossil fuel crunch point is likely within decades as alternatives become cheaper and fossil fuels meet a supply and demand crisis. In the interim HELE coal technology is cost competitive and non polluting. In the land use sector returning some of the 500 GtC – some 40% more than all fossil fuel emissions since 1750 – lost from soils and vegetation since the advent of agriculture has food security, environmental and flood and drought mitigation benefits worth doing for these reasons alone. It is the most promising project to emerge from the Paris climate accord. 56 countries have signed on – but success depends on bottom up action by farmers and indigenous land owners. Millions of those have signed on.
