El Cid   213 #1 Posted July 30, 2015 Our climate affects all areas of life, directly or indirectly, and climate change will have wide-ranging impacts.  The temperature record shows rising temperatures from around 1910, with a dip in 1945, then on the rise again from the 1970s.  https://en.wikipedia.org/wiki/Temperature_record  I am guessing most of that rise has been beneficial, at what point does it start to be negative? 2014 was the hottest year on record, are certain countries now getting too hot; how about the UK, our climate has changed.

Could someone bother to inform whoever's running the weather of the fact?  I wouldn't mind some warming sometime soon, summer's been pretty miserable so far, and most of July downright 'orrible  Parents living near the Alsace have been enjoying 30+C every day (around 24C at night) for the past month and a bit, non-stop (wherein it eventually stops being so enjoyable...so I'm told ). Now, I can remember summers like that 30-odd years ago, and every now and then since. Share this post Link to post Share on other sites Share this content via...

Cyclone   10 #5 Posted July 30, 2015 It suggests that we are lucky that we're not plunging back into an ice age from the current inter-glacial, which has lasted longer than is normal and effectively allowed the civilisation we have to exist.

El Cid   213 #7 Posted July 30, 2015 Soil temperature at 0900 GMT (1915) 16.1 - at 30 cm depth, C 16.0 - at 2 feet depth, C  Soil temperature at 0900 GMT (2005) 17.5 - at 5 cm depth, C 16.0 - at 10 cm depth, C 16.0 - at 20 cm depth, C 16.9 - at 30 cm depth, C 17.0 - at 50 cm depth, C 16.2 - at 100 cm depth, C  http://www.met.reading.ac.uk/~brugge/reading_past_weather.html  Although its only a small difference between 1915 and 2005, that is roughly the difference on the first graph, in line with climate change. Is that correct? Where is your data from retep? Share this post Link to post Share on other sites Share this content via...

This is because the measurement was within uncertainties/errors of several other years. It's not exactly a lie, but it's unlikely to be true.  That's before we even get into the matter that the temperature records in question are routinely "adjusted".  Basic global warming science says that a doubling of the CO2 level should increase global temperatures by 1C. Climate modellers say that in their simulations this rises to 1.5-4.5C. When one states that one "believes in climate change" it is necessary to specify whether this is basic global warming science or the simulations and furthermore which simulations since the results vary by a factor of 3.

Without a proper explanation as to why they have been adjusted, and since the raw data are not made available; I find it highly dubious.

Cyclone   10 #12 Posted July 30, 2015 Urban heat islands would be a reason to adjust the data down, not up.  Highly dubious, ie sceptical of any hypothesis is the correct position to start from. You test the predictions with the intention of falsifying the hypothesis. Assuming that they actually make any testable predictions and actually qualify as a hypothesis.
