  1. Berkeley Earth has just released analysis of land-surface temperature records going back 250 years, about 100 years further than previous studies. The analysis shows that the rise in average world land temperature globe is approximately 1.5 degrees C in the past 250 years, and about 0.9 degrees in the past 50 years. http://berkeleyearth.org/summary-of-findings?/results-summary/
  2. I'm not so sure the ENS is quite so optimistic SS. Mind shouldn't pin much on it yet anyway.
  3. Australia leads the way.......................................................... Is Maurice Newman telling Tony Abbott he should fire him?http://blog.hotwhopper.com/2014/04/is-maurice-newman-telling-tony-abbott.html
  4. Not only that those annoying scientists (surely not experts?) are perpetuating this iconic propaganda. It really is beyond the pale. http://www.reuters.com/article/2008/04/11/us-sweden-tree-idUSL1190625120080411
  5. The GFS is still going for unsettled weather for the weekend and into next week with low pressure controlling the scene with temps becoming below average next week. The upper air shows cold air over the UK at the weekend and by Wednesday this has intensified over the north North Sea with a trough extending to the south west approaches translating on the surface to a low situated SW of Cornwall with the UK in a mainly easterly flow and below average temps. The ECM ens is not dissimilar although the more intense upper cold air is displaced further east. At this stage the weather looks to remain unsettled with some negative anomaly temps although after that way out so completely unreliable at the moment the GFS has a strong build up of heights over the UK.
  6. With ref. to Reef's post above just a touch of whimsy.
  7. A 9,950-year-old Norway spruce.The mass of branches near the ground grew the same way for roughly 9,500 years, but the new, spindly trunk in the center is only 50 or so years old, caused by warming at the top of this mountain plateau in Western Sweden.

  8. A wet night with moderate rain but ceased at the moment with the front lying across the south west. Temp 11C Wind southerly light.
  9. Remember this, Arctic Sea Ice Downfall and Godwin's Law.(Warning some bad language)
  10. As we have been looking at winter.A picture is worth more than 1,000 words or 140 charts: http://data.giss.nasa.gov/cgi-bin/gistemp/nmaps.cgi?sat=4&sst=3&type=anoms&mean_gen=1203&year1=2014&year2=2014&base1=1951&base2=1980&radius=1200&pol=rob …
  11. I think you will find that BOM refuted that slander with a very in depth reply that was produced on here. In fact I remember being surprised the original comment was allowed to remain for legal reasons.
  12. The ECM ens upper air still much the same with colder dominating into the near future and still a lousy weekend. A hint on the GFS of a more stable upper pattern into lulu land.
  13. An in depth look............................. How the world failed on climate changehttp://www.vox.com/2014/4/22/5551004/two-degrees
  14. http://forum.netweather.tv/topic/76448-scepticism-of-man-made-climate-change/page-61#entry2959646 Really. The 33rd coldest winter since 1895. Source NCDC. I suggest you look at the source of the other chart. EDIT Sorry Dev. didn't see your post.
  15. http://forum.netweather.tv/topic/76448-scepticism-of-man-made-climate-change/page-61#entry2959627 Even more interesting. The 32nd coldest six months since 1895. Source NCDC.

  18. http://forum.netweather.tv/topic/76448-scepticism-of-man-made-climate-change/page-61#entry2959582 If this was in paper form rather than digital the article could take pride of place in the smallest room in the house.

  20. I'm just guessing what you are getting at but primarily don't get obsessive about CO2 alone. The earth was a different place then. Perhaps to start. http://www.skepticalscience.com/co2-higher-in-past.htm And this may help more. http://www.wunderground.com/blog/JeffMasters/article.html?entrynum=1453
  21. Yes the Holocene is an interesting study. Of course one mustn't forget that the loony lefties wrote the papers. The climatic changes that occurred at high latitudes during the Holocene were a result of the combined effects of several different forcing factors operating on different timescales, coupled with feedbacks within the Earth system itself. On the longest, millennia! and multimillennial timescale changes took place in the orbital characteristics of the Earth (eccentricity, precession and obliquity; ) relative to the Sun, resulting in variations in the seasonal and latitudinal receipt of solar radiation, although there was virtually no change in the total amount of radiation received by the Earth over the course of the year as a whole. However, changes in the solar radiation emitted by the Sun had an impact on the amount of energy received at the top of the atmosphere. Although this was felt proportionately across the whole of the Earth, the impact on surface conditions varied across the globe because offeedbacks involving cloud, ice and other elements of the Earth system. Variations in the Earth's orbit around the Sun have the potential to force major changes in the climate system and work by the Cooperative Holocene Mapping Project (COHMAP) (COHMAP members, 1988) suggested that orbital changes could explain in broad terms the climatic variations since the LGM at about 18 kyr BP. Short-term climate events, which can be extremely important on a regional scale, were not considered. During part of the Early Holocene, over 11-9 kyr BP, summer insolation in the Northern Hemisphere was about 8% greater than today due to a difference in orbital precession that aligned the boreal summer solstice with the perihelion (the closest approach of the Earth to the Sun). This gave greater levels of summer insolation at all latitudes of the Northern Hemisphere, with locations at 60° N receiving about 40° W m-2 more radiation than today (Bradley, 2003). Conversely, January insolation was 8% less than today. During the course of the first half of the Holocene the orbital conditions changed so that the present situation of perihelion occurring close to the winter solstice was reached by the Mid Holocene. In the Early Holocene insolation anomalies in the Southern Hemisphere summer were smaller than in the north and they mainly occurred at lower latitudes. The fact that the greatest change in the Early Holocene occurred in the summer was especially important in the Arctic, when the ice-albedo feedback mechanism is most effective and changes in irradiance can be amplified and result in broadscale loss of sea ice. Although there is a good understanding of how the changes in orbital characteristics resulted in variations in the solar radiation received at the top of the atmosphere during the Holocene, it is less clear how such changes to the solar input translated into modifications to the climatic parameters at high latitudes. There are no simple relationships between incoming solar radiation and parameters such as cloud cover or temperature since feedback mechanisms will play an important role, especially in the polar regions. In addition, model simulations have suggested that on the margins of the Arctic, vegetation feedbacks could have played a role in modifYing the changes in solar forcing (TEMPO, 1996).
  22. Today's Antarctic region once as hot as California, Florida http://www.sciencecodex.com/todays_antarctic_region_once_as_hot_as_california_florida-132150
  23. The ECM ens paints a picture of unsettled weather. Certainly this week with the MSL anomaly not good at the weekend. Then after that the upper pattern is predominately colder air via the Atlantic so remaining unsettled.

  25. The 00z GFS still going for unsettled week culminating with a depression 996hPa in the Channel at 12z midday Sunday.
