Sentences with phrase «effect on the global temperature record»

While these adjustments don't have a big effect on the global temperature record, they are needed to obtain consistent local records from equipment which has changed over time.

Not exact matches

With an El Niño expected to develop late this summer or in the fall, there is a chance that 2014 could move into the spot as the warmest year on record, though the climate phenomenon's effects are generally most pronounced in the colder months, so the boost it gives to global temperatures could be reserved for 2015.

To contribute to an understanding of the underlying causes of these changes we compile various environmental records (and model - based interpretations of some of them) in order to calculate the direct effect of various processes on Earth's radiative budget and, thus, on global annual mean surface temperature over the last 800,000 years.

Finally the knock - on effects wore off and a return to a particularly strong El Nino culminated in the record global temperatures of 1998.

«Our results show that temperature records of at least 17 years in length are required for identifying human effects on global - mean tropospheric temperature.»

Thompson et al. do not provide a time series estimate on the effects of the bias on the global temperature record, but Steve McIntyre, who is building an impressive track record of analyses outside the peer - review system, discussed this topic on his weblog

Hawkins and Jones (2013) focused on one small aspect of Callendar's work: his compilation of World Weather Records station temperature data into zonal and global temperature anomalies, in effect, delimiting Callendar, whose contribution was much more diverse, as a sort of John the Baptist of temperature accountancy, merely preparing the way for Phil Jones.

If increase in CO2 concentration had effect on the global mean temperature, why is its trend constant since record begun in 1850 as shown?

If this is accepted as a reasonable looking proxy for ocean heat content which matches the instrumental OHC record pretty well, then no «lag» is needed to explain the solar effect on OHC and thus global surface temperature.

He rewrote Wikipedia's articles on global warming, on the greenhouse effect, on the instrumental temperature record, on the urban heat island, on climate models, on global cooling.

@Mike Edwards: There are lots of studies — hundreds, at least — of the urban heat island effect, and quite a lot of effort has gone into identifying, quantifying, modelling, and adjusting for the effect of UHI on global temperature records.

Ben Santer in a 2011 paper «Our results show that temperature records of at least 17 years in length are required for identifying human effects on global - mean tropospheric temperature.»

Santer et al. argue that «Our results show that temperature records of at least 17 years in length are required for identifying human effects on global - mean tropospheric temperature.»

One must define down «global mean temperature» to focus on surface temps (not effected by the greenhouse effect) and a few other narrow things, and to make up just the right combination of ways of extrapolating from what are actually a relative dearth of samples, in order to come up with this «record - breaking» system.

So if stations with discontinuous records in GHCN tend to have a colder absolute temperature than stations with continuous records, it will have no real effect on the global anomaly as long as the the change in temps over time is unrelated to the baseline temp.

It should be noted that whilst BEST claim no discernible effect of UHI on their record the UK Met Office acknowledges corrections of up to 1.5 C for this, largely to the minimum temperatures where most global warming is found.

E.g., research assumes greenhouse gas emissions cause warming without explicitly stating humans are the cause»... carbon sequestration in soil is important for mitigating global climate change» (4a) No position Does not address or mention the cause of global warming (4b) Uncertain Expresses position that human's role on recent global warming is uncertain / undefined «While the extent of human - induced global warming is inconclusive...» (5) Implicit rejection Implies humans have had a minimal impact on global warming without saying so explicitly E.g., proposing a natural mechanism is the main cause of global warming»... anywhere from a major portion to all of the warming of the 20th century could plausibly result from natural causes according to these results» (6) Explicit rejection without quantification Explicitly minimizes or rejects that humans are causing global warming»... the global temperature record provides little support for the catastrophic view of the greenhouse effect» (7) Explicit rejection with quantification Explicitly states that humans are causing less than half of global warming «The human contribution to the CO2 content in the atmosphere and the increase in temperature is negligible in comparison with other sources of carbon dioxide emission»»

On the basis of our results, a 1 °C rise in environmental temperature would account for over 100 000 new diabetes cases per year in the USA alone, given a population of nearly 322 million people in 2015.38 These findings emphasize the importance of future research into the effects of environmental temperature on glucose metabolism and the onset of diabetes, especially in view of the global rise in temperatures with a new record set for the warmest winter in the USA last year.On the basis of our results, a 1 °C rise in environmental temperature would account for over 100 000 new diabetes cases per year in the USA alone, given a population of nearly 322 million people in 2015.38 These findings emphasize the importance of future research into the effects of environmental temperature on glucose metabolism and the onset of diabetes, especially in view of the global rise in temperatures with a new record set for the warmest winter in the USA last year.on glucose metabolism and the onset of diabetes, especially in view of the global rise in temperatures with a new record set for the warmest winter in the USA last year.39

Michaels also suggests that temperatures in 2015, while still being «the highest average surface temperature in the 160 - year global history since reliable records started being available,» had a «de minimis» effect on the global economy.

Old positive feedback examples in climate change... «Feedback Loops In Global Climate Change Point To A Very Hot 21st Century Using deuterium - corrected temperature records for the ice cores, which yield hemispheric rather than local temperature conditions, GCM climate sensitivity, and a mathematical formula for quantifying feedback effects, Torn and Harte calculated the magnitude of the greenhouse gas - temperature feedback on temperature.»

These methods include inference of surface temperature change from vertical temperature profiles in the ground (bore holes) at many sites around the world, rate of glacier retreat at many locations, and studies by several groups of the effect of urban and other local human influences on the global temperature record.

Via Discovery, New Scientist More Beer & Alcohol Top Green Beer Drinking Tips The Worst Effect of Global Warming So Far... 8 College - Town Breweries Producing Great, Green Beer More on Global Warming Science Global Ocean Temperatures Warmest Since Records Began in 1880 (129 Years Ago!)

The overall effect on global temperature is small, however (Figure 2.7 c) The five warmest global optimally averaged years since the beginning of the record in 1861 all occurred in the 1990s with 1998 having the warmest anomaly (0.55 °C).
