Being fooled by climate change

Are you being fooled by climate change?
Should we blame Chicagoland meteorologists and the TV-radio weather-casters for misleading you on local weather and climate change?

Daily highs in the 70s and 80s are not normal for early October in the Upper Midwest.

Although the meteorologists acknowledge the latest warmer than usual temperatures when broadcasting their summaries, they follow their summaries with misleading comments about "back to reality" and "back to normal", based on their forecasts for cooler days ahead.

But reality is that the "days ahead" often are not as cool as they had figured and told you, especially the overnight low temperatures.

Why are meteorologists and TV weather-casters so "in the dark" about global warming?

The meteorologists and weather-casters are contributing to a "do nothing" approach on
global warming. They are misleading you into thinking that your weather has been just normal ups and downs, but obvious warming TRENDS are overlooked.

No, we are not experiencing just normal weather conditions. The climate is changing rapidly. We are experiencing enhanced global warming, mainly due to our emissions of greenhouse gases from our fossil fuel burning. CO2 is accumulating in the atmosphere at a dangerously rapid rate, which is likely to threaten the continuation of life on earth as we know it.

Sea Ice Decline Intensifies

For the fourth consecutive year, NSIDC and NASA scientists using satellite data have tracked a stunning reduction in arctic sea ice at the end of the northern summer. The persistence of near-record low extents leads the group to conclude that Arctic sea ice is likely on an accelerating, long-term decline. ...

Arctic sea ice extent, or the area of ocean that is covered by at least 15 percent ice, typically reaches its minimum in September, at the end of the summer melt season. On September 21, 2005, the five-day running mean sea ice extent dropped to 5.32 million square kilometers (2.05 million square miles), the lowest extent ever observed during the satellite record (Figures 2 and 3:
Five-day running mean). ...

Florence Fetterer, of NSIDC, explained how the situation has changed. “Even if sea ice retreated a lot one summer, it would make a comeback the following winter, when temperatures fall well below freezing,” she said. “But in the winter of 2004-2005, sea ice didn't approach the previous wintertime level.” This lack of recovery means that the sea ice is not building back up after a summer of melting—leaving it even more susceptible to warmer summer
temperatures. ...

This is a joint press release between the National Snow and Ice Data Center (NSIDC), a part of the Cooperative Institute for Research in Environmental Sciences at the University of Colorado, Boulder; NASA; and the University of Washington. ... see ref url.
