«Most climate models that incorporate vegetation are built on short - term observations, for example of photosynthesis, but they are used to predict long - term events,» said Bond - Lamberty, who works at the Joint Global Change Research Institute, a collaboration between PNNL and the University of Maryland in College Park, Md. «We need to understand forests in the long term, but forests change slowly and researchers don't live that long.»

The study reveals the importance of long - term observations at key locations of the global ocean circulation.

Current studies include the exploration of Arctic deep - sea life under the ice, and the long - term observation of the effects of global warming on polar ecosystems as well as on hypoxic aquatic ecosystems.

Complementary ground - based observations can probe atmospheric global region remotely and can provide long - term coverage.

In the global mean, there isn't much of an issue for the mid-troposphere — the models and data track each other when you expect they would (the long term trends or after volcanoes, and don't where you expect them not to, such as during La Niña / El Niño events which occur at different times in models and observations).

What observations do you offer that would encourage this other than claiming the last 3 years (2005 hottest) or last twelve (’98 hottest) equal global cooling when they are all among the hottest years in the last 2 million (a fundamentally flawed assertion that shows 100 % ignorance, or willful disregard, of basic scientific principles, namely that a three — twelve year period is not a long - term trend, but is variability until proven otherwise.)

The only way the models can be wrong (in direction) is if they have grossly underestimated natural variability, and a global cooling trend is established in the long term observations.

We can write down a simple recipe for the GHE, but it is indeed challenging to reconcile a presence of a negative feedback with our observations, or explain the current observed global warming in any other terms.

Like I say, you see a richness of behaviour in the models including in some occasions behaviour that at first sight looks not dissimilar to that highlighted in the observations by the Thompson paper and this on top of the «external control» as we called it in our 2000 paper in Science of the external forcings in a particular model which drives much of the multi-decadal hemispheric response in these models and which, in terms of the overall global warming response, is dominated by greenhouse gases.

Near - term projections of global average temperature, updated with latest global temperature observations and forecasts.

Interpreting these observations further we do have more evidence of global warming by the first observation, but based on the second observation we do have evidence that the longer term trend is likely smaller than many thought based on data up to 2000.

So I asked Mr. Knappenberger to test the models» agreement with long - term observations using a new «third» scenario in which internal variability once again «enhances» the «externally forced trend» and global warming resumes at the 1984 - 1998 rate of 0.265 ºC / decade.

This finding is compatible with the observation that conservative think tanks use the term «global warming» more often than «climate change,» whereas liberal think tanks use «climate change» more often than «global warming.»

While the climate change signal is much clearer in the northern latitudes - where longer - term records show a relatively steady retreat of Arctic sea ice - evidence of global warming's impact around Antarctica is also showing up in the observations.

Vamborg then illustrated how observation data feeds into monitoring long - term change and gave a climate overview of 2017 at both a global and European level.

Global Warming Theory «Completely Disconnected From the Observations» Extensive analysis of temperature trends in the Arctic reveals that there has been no detectable long - term change since the beginning of the 20th century, and thus predictions of a sea ice - free Arctic in the coming decades due to dramatically rising temperatures are not rooted in observation.

The lack of an oscillatory model signal suggests that the inter-decadal global mean surface temperature signal derived from the observations and shown in Figs. 1A and 2B is indeed the signature of natural long - term climate variability.

Observations of recent global warming, short - term cooling after major volcanic eruptions, cooling at the Last Glacial Maximum and other periods in the historical record, and the seasonal variation in climate, all provide some information which helps to determine the value of climate sensitivity.

Around 90 % of all reasonably long - term observations show changes consistent with global warming and associated effects.

The team — led by Dole, Hoerling, and Judith Perlwitz from the Cooperative Institute for Research in Environmental Sciences at the University of Colorado in Boulder — sifted through long - term observations and results from 22 global climate models, looking for trends that might help explain the extraordinarily high temperatures in western Russia during the 2010 summer.

Southern hemisphere observations of a long - term decrease in F region altitude and thermospheric wind providing possible evidence for global thermospheric cooling

I work with various global data every day and I can't believe how little progress we made in the last 20 years in terms of Earth observations.

I suspect that none will take on this challenge: (a) You are not a PHOSTA and lack the background, knowledge and critical thinking skills it takes to understand the existing data and its implication in terms global geochemical systems; (b) You will be unable to find through literature research or create via experiment or observation the data needed to come to a self - consistent derivation and will thus ignore this challenge in the face of embarrassment; or (c) You will want to conveniently ignore the myriad of data presented by Bohm and others since these data contradict your theory and your working studiously to prove otherwise is, well, just inconvenient.
