Sentences with phrase «warming signal»

Even amateur «scientists» have replicated the global rise in temperatures using as little as 10 % of the station data because there is a global warming signal in the data.

For example a paper on measuring the global warming signal in the instrumental temperature record may say nothing about the cause.

Warm records are set through the 1930s and 40s, with a long stretch of no records until the 1980s, when the global warming signal firmly emerges from the noise of natural variation.

That the noise of natural variability can temporarily be strong enough to make the underlying warming signal seem to «disappear» for short periods is nothing new.
