Alarmist’s change theories like underwear.

Good to see alarmists are at it again. First, its permanent droughts. Then catstrophic hotspots. Then record breaking heatwaves.

None of those things are happening. So, then it was freezing caused by warming. Floods caused by warming oceans.

Whatever happens, Climate Change caused it.

The Arctic has now reached a record low extent since satellites started measuring the extent in 1979.

However, the Antarctic has now reached a record for gains in extent, and the net balance is that the ice is normal.

The alarmist do not mention this, nor do they mention the fact that the main area of warmth was supposed to be in Antarctica.

Maybe they have lost the publication of the IPCC AR4 report? Or has alzheimers’ clicked in?

Whatever the reason, the models are a joke.

Here is a small snippet showing that Antarctic Ice is expected to decrease, when in fact its increasing.

In 20th- and 21st-century simulations, antarctic sea ice cover is projected to decrease more slowly than in the Arctic (Figures 10.13c,d and 10.14), particularly in the vicinity of the Ross Sea where most models predict a local minimum in surface warming. This is commensurate with the region with the greatest reduction in ocean heat loss, which results from reduced vertical mixing in the ocean (Gregory, 2000). The ocean stores much of its increased heat below 1 km depth in the Southern Ocean. In contrast, horizontal heat transport poleward of about 60°N increases in many models (Holland and Bitz, 2003), but much of this heat remains in the upper 1 km of the northern subpolar seas and Arctic Ocean (Gregory, 2000; Bitz et al., 2006). Bitz et al. (2006) argue that these differences in the depth where heat is accumulating in the high-latitude oceans have consequences for the relative rates of sea ice decay in the Arctic and Antarctic.

Figure 10.14. Multi-model mean sea ice concentration (%) for January to March (JFM) and June to September (JAS), in the Arctic (top) and Antarctic (bottom) for the periods (a) 1980 to 2000 and b) 2080 to 2100 for the SRES A1B scenario. The dashed white line indicates the present-day 15% average sea ice concentration limit. Modified from Flato et al. (2004).
