Beginning in the 14th century, the North Atlantic region Patient experienced a cooling that lasted until the mid-19th century Duration . [ RAPPORTPENTAGONE 0 MCLH 07/02/2014 ]

Although many regions of the world Patient experienced cooling during the period 1450 to 1890 A.D., with average surface temperatures in many regions at least 1°C lower than those of today, its use has been criticised because it has not conclusively been considered to be an event of global significance. [ ENCY 0 MCLH 07/02/2014 ]

The spatial pattern of the increase also did not show some of the areas of surface Patient cooling evident in climate observations. [ 1CANADACCD 0 MCLH 07/02/2014 ]

Alternatively, the cooling of the Northern Hemisphere Patient may lead to increased warmth, precipitation, and storms in the south, as the heat normally transported away from equatorial regions by the ocean currents becomes trapped and as greenhouse gas warming continues to accelerate. [ RAPPORTPENTAGONE 0 MCLH 07/02/2014 ]

Yet it appears to continue to grow, undoubtedly as a result of the cooling of the stratosphere Patient , and possibly due to the increase in greenhouse gases. [ CHANG JACLET 0 MCLH 07/02/2014 ]

Drier soils can also add to the intensity of daytime temperatures by reducing cooling from surface evaporation Cause . [ 1CANADACCD 0 MCLH 06/06/2018 ]

These natural factors Cause should have caused a cooling, and hence cannot explain the recent warming trend (Figure 3.3a). [ 5CANADAICC 0 MCLH 06/06/2018 ]

There is evidence that accompanying controls on CH4 emissions would offset some of this sulphate-induced warming, although the cooling from CH4 mitigation Cause will emerge more slowly than the warming from sulphate mitigation due to the different time scales over which atmospheric concentrations of these substances decrease in response to decreases in emissions. [ WG1AR5AM 0 MCLH 07/06/2018 ]

The drop in atmospheric CO2 around year 1600 could also be caused by a cooling from increased volcanic eruptions Cause [ WG1AR5FF 0 MCLH 07/06/2018 ]

These aerosols, which are predominantly composed of sulphates Cause , are highly effective reflectors of incoming sunlight, and, during peak concentrations following such eruptions, can cause a net Descriptor surface Patient cooling of up to 0.5 ° C Value . [ 3CANADAENVIRON 0 MCLH 07/06/2018 ]

The increase in the concentration of greenhouse gases should add to the surface Patient warming, a similar warming at low altitude, followed by a cooling of the stratosphere. [ JACLET 0 MCLH 06/06/2018 ]
