That chart is missing 5 years of data. Please link to the actual data: http://data.giss.nasa.gov/gistemp/graphs_v3/ http://data.giss.nasa.gov/gistemp/graphs_v3/ Before you see the data for 2009-2013, maybe you should make a prediction of their values.
- anon1385 12y ago>maybe you should make a prediction of their values. 4 years is a really tiny meaningless sample in terms of climate. However, here is what you asked for up to 1998, with a continuation of the linear trend in red, and a 'pause' in blue (I only have a 'before' graph for HADCRUT4 rather than GISS, but there isn't much difference - GISS and other temp records can be seen at the link). http://tamino.files.wordpress.com/2014/01/hadcrut4_98.jpg http://tamino.files.wordpress.com/2014/01/hadcrut4_98.jpg Maybe you would like to make a prediction?

- sparkie 12y ago25 years is also a really tiny meaningless sample in terms of climate. Are we forgetting that we have a solar cycle of 22 years? We can't tell shit from such small periods.
- anon1385 12y agoYes I agree. I do find the obsession with plotting linear regressions of temperature data fairly strange, since surely even the most ardent climate skeptic accepts the existence of solar cycles (and volcanism etc). Once you accept that there are external drivers of the climate system, I don't know why you would ignore what they have been doing. Anyway, I'm not the one trying to claim that there is suddenly no longer an energy imbalance in the climate system because of a decade of (incomplete) surface temperature data. I do think it's worth pointing out how cherry picked the 'pause' argument is though, even on its own terms.
- pyre 12y agoI thought that I remember the solar cycle being claimed as 11 years. Is this new?
- lutusp 12y agoThe OP might be trying to say that 25 years conflicts with two solar cycles. Because it is in fact an 11-year cycle.
- oxalo 12y agoDid anyone notice in those graphs that the temperature anomaly for the southern latitudes/ hemisphere seemed lower than for the northern latitudes/ hemisphere? Anyone know why that would be?
- happyscrappy 12y agoMore ocean.
- DennisP 12y agoIf you want to say it leveled off in the past five years, fine, but there are several other such periods earlier in your graph, and the overall warming trend is still glaringly obvious. Cherrypicking one unusually hot year in the 90s as the standard of comparison isn't valid. (Relying solely on air temperature isn't really valid either. Heat is also absorbed by the ocean and by melting ice.)
- DennisP 12y agoAnd to that last point, the Greenland and Antarctic ice sheets are melting twice as fast as they were five years ago. http://www.huffingtonpost.com/2014/08/21/antarctica-greenland-melting-ice_n_5697998.html http://www.huffingtonpost.com/2014/08/21/antarctica-greenlan...
