What is your prediction? For example, while it’s just a guess Salvatore Del Prete (3-Mar-2011) believes temperatures may be, 2F to 3F colder than they are now by the end of this decade.
He points out that the solar/volcanic activity and natural oscillations have, ‘all been phasing from a cold mode to warm mode, overall, starting around 1700 AD or so.’ And, Del Prete says it was, ‘late 2005 when the trends started to reverse.’
‘Last century,’ according to Del Prete, ‘we had record high solar activity, limited volcanic activity, SOI oscillation mostly negative, AO/NAO mostly positive, and PDO/AMO mostly in a warm phase… [accounting] for the overall temperature rise.’
‘In contrast,’ however, he says that, ‘this decade will more than likely, continue to see low solar activity, more volcanic activity, SOI oscillation being more positive, AO/NAO circulations being more negative, and PDO/AMO being mostly in a cold phase. The result will be colder temperatures.’
A key assumption in his prediction is that, ‘solar activity remains low,’ and by low he means, ‘an average solar flux reading of between 70 and 100.’ And what do other scientists believe concerning future solar activity? Del Prete noted a study on the climaterealist web-site showing that, 80.6% of the largest earthquakes/most volcanic activity correlates with low solar activity.
‘Right now,’ Del Prete says that according to ‘the best solar scientist that I follow, they are expecting the sun to remain in a Dalton Minimum type period, which should last to 2035 or so. If correct that will mean colder temperatures overall, up to at least 2035.’
