UN Report: Climate Changes Overwhelming
iONiUM (530420) writes "'The impacts of global warming are likely to be "severe, pervasive and irreversible", a major report by the UN has warned.' A document was released by the IPCC outlining the current affects on climate change, and they are not good. For specific effects on humans: 'Food security is highlighted as an area of significant concern. Crop yields for maize, rice and wheat are all hit in the period up to 2050, with around a tenth of projections showing losses over 25%.'"
The observed temperatures are currently below the error bars of the most optimistic projection. What does this mean?
It means you are reading BS that does not reflect *reality*.

The combined average temperature over global land and ocean surfaces for February 2014 tied with 2001 as the 21st highest for February on record, at 0.41C (0.74F) above the 20th century average of 12.1C (53.9F).
The global land surface temperature was 0.31C (0.56F) above the 20th century average of 3.2C (37.8F), tying with 1943 as the 44th highest for February on record. For the ocean, the February global sea surface temperature was 0.45C (0.81F) above the 20th century average of 15.9C (60.6F), making it the seventh highest for February on record.
The combined global land and ocean average surface temperature for the Decemberâ"February period was 0.57C (1.03F) above the 20th century average of 12.1C (53.8F), making it the eighth warmest such period on record.
Here in Vermont, a few years back they redrew the flood maps, and a large number of people ended up being added to the flood areas. This cause a lot of outcry for people who suddenly had to buy flood insurance in order to keep their mortgages. Of course, they stopped whining after Hurricane Irene hit and caused a ton of flood damage and taking out a lot of houses that had just started being covered by flood insurance...
"The observed temperatures are currently below the error bars of the most optimistic projection. What does this mean?"
What it means is that as evidence of any actual greenhouse warming effect from CO2 grows thinner, and contrary science continues to build momentum, and evidence of -- shall we say -- "irresponsible" handling of data by climate alarmists is mounting... the cries of gloom and doom become ever more strident and shrill. That in itself is evidence that it is a scheme for more government control, rather than good science.
Worst thing is that it is a world wide scheme. All scientists and all the world's governments are in collusion on this. It is even worse than how they all try to brainwash our kids into thinking we are related to apes.
You can go to the bottom of the report page 38 for a chart and review the differences in the between a "low emission mitigation scenario" RCP 2.6 (one that we try to help the problem) and a high emission scenario (where we keep on keepin on.) RCP 8.5.
While temps go up for both, the mitigation scenario leads to a much more livable planet, closer to the one we live in today. the difference between scenarios is stark, an average of 3C difference by 2100. Children born today could easily live to see 2100, they would be 86 years old. So for me in Houston TX that means a hot summer day that was 100F will be 105.5F. The mitigation scenario could reverse the warming trend as early as 2050. You are correct that even the best case scenario doesn't allow for a return to current temperatures by 2100. In my mind the question is how long until we realize we our saving our own skins and make some hard decisions. Everybody want's a livable planet, but nobody want's to be the first to make the sacrifice.
TODO create witty sig.
2010 and 2011 were La Niña years, i.e., years where the sea surface temperature is 3-5 degrees celcius below normal. What you're seeing is weather, not climate.
Now, if it continues like that for another ten-fifteen years, our models were wrong and you'll see me running in the street, celebrating.
It may be colder than normal in some specific places (like the eastern part of the United States). In spite of that, worldwide temperatures are way above average (NASA released a report recently saying 2013 was one of the warmest years on record and every year in the top-10 was in the last 15 years).
