Sentences with phrase «with urban heat bias»

Not exact matches

And while some warming delusionists have tried to claim biases associated with urban heat islands (the most recent effort, led by Anthony Watts, was a total fizzle) an IPCC admission that the planet had only warmed half as much as we thought would be a big story indeed.

2) Some stations must be biased warm by urban heat islands, but their influence on the global trend can't be detected with any of the techniques available for separating urban and non-urban stations.

Having worked with many of the scientists in question, I can say with certainty that there is no grand conspiracy to artificially warm the earth; rather, scientists are doing their best to interpret large datasets with numerous biases such as station moves, instrument changes, time of observation changes, urban heat island biases, and other so - called inhomogenities that have occurred over the last 150 years.

When I said «There are also significant positive minimum temperature biases from urban heat islands that add a trend bias up to 0.2 C nationwide to raw readings», I should have said «There are also significant positive minimum temperature biases from urban heat islands, with urban stations warming up to 0.2 C faster than rural stations».

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.

This is called the urban heat bias, and as with solar effects, scientists tended to think the effect, while real, was relatively minor.
