Sentences with phrase «then estimates of global temperature»

Not exact matches

Some studies have attempted to estimate the statistical relationship between temperature and global sea level seen in the period for which tide gauge records exist (the last 2 - 3 centuries) and then, using geological reconstructions of past temperature changes, extrapolate backward («hindcast») past sea - level changes.

It's incredibly hypocritical of global warming denialists to whine that compilations of global temperature anomaly like GISTEMP have large distances between recording stations and this makes them an inaccurate estimate of global anomaly and then we have a global warming denialist extraordinaire, Roberts, claim that a SINGLE locality, Central England, can provide an adequate estimate of global anomaly.

If the GHG - temperature link is on the low end of the range of estimates (1.5 C to 4.5 C per doubling), then global warming will not be a significant problem.

The SkyShares model enables users to relate a target limit for temperature change to a global emissions ceiling; to allocate this emissions budget across countries using different policy rules; and then uses estimated marginal abatement costs to calculate the costs faced by each country of decarbonising to meet its emissions budget, with the costs for each country depending in part on whether and how much carbon trading is allowed.

If a substantial fraction of all the weather stations from around the world have been affected by urbanization bias, then this could have introduced an artificial warming trend into the «global temperature trend» estimates.

We then used this new estimate of unforced variability to aid in our interpretation of observed global mean temperature variability since 1900.

So, they didn't actually simulate sea level changes, but instead estimated how much sea level rise they would expect from man - made global warming, and then used computer model predictions of temperature changes, to predict that sea levels will have risen by 0.8 - 2 metres by 2100.

Then, it might be possible to make some meaningful estimates of long - term global temperature trends from the weather records.

The principal work of climate modeling is to take a complete census of all of these factors, estimate the sizes and trajectories of their various effects, and then add them up to estimate future global temperatures.

Then using an estimate of 14.0 C for the global temperature average of the 20th century, 12 - month absolute temperatures were calculated from the calculated 12 - month average anomalies.

The effects of this uneven sampling are being investigated and quantified in several ways, for example by estimating «true» global - mean temperatures from the complete fields generated by satellite observations, blends of satellite and in situ data, or climate models, and then sampling these fields using the actual (incomplete) observed data coverage (see chapter 9).

The physics of the climate system are input into very detailed climate models, which can then estimate how the global temperature will respond to various forcings.

Since then, a growing number of surface temperature measurement stations worldwide, coupled with improved methods for correcting for biases induced through urban heat island effects and other station siting and operational issues, have allowed for the development of accurate global temperature estimates.

Since then, significant improvements in methodology, a vast increase in the available stations, and the inclusion of marine data have greatly improved estimates of global temperatures.

Each group then uses its chosen subset to create estimates of how global temperatures have changed over time and how they may change in the future.

So I estimate that if we followed IEO2011 / RCP8.5 out to 2035, and then stabilized our forcing, we would eventually arrive at an average global temperature increase of 2.4 ºC.

The Sun was then about 0.25 percent dimmer, and the reduction in solar brightness produced an estimated drop of about 0.5 degrees Celsius (0.9 degrees Fahrenheit) in the global mean temperature.
