Sentences with phrase «background temperatures rise»

Not exact matches

Even with a long - term background trend of rising temperatures, other climate factors contribute to yearly ups and downs.

Such signatures tell us that during the PETM, temperatures rose rapidly over approximately 6,000 years, and then gradually cooled to near - background levels over the next 150,000 — 200,000 years.

It is certainly not the cause of the temperature rise, which you yourself attribute to background radiation.

This pattern masked (my conjecture) a «background» rise in global temperatures over that period, instead making it look like there was a rise circa 2000 - 2001 rather than 1995 - 2001.

An increase in CO2 from current levels causes a rise in global temperatures that is so small that it can not be detected against the background of natural noise.

Jim Cripwell writes: «An increase in CO2 from current levels causes a rise in global temperatures that is so small that it can not be detected against the background of natural noise.»

«The Australian National University announced the discovery on Sunday, claiming evidence shows human - caused greenhouse gas emission during the past 45 years has increased the rate of temperature rise to 1.7 degree Celsius per century, «dwarfing the natural background rate,» according to Will Steffen, a climate change expert and ANU professor.»

Because if their hypothesis were merely that an increase in CO2 would cause only a negligible rise in temperature, which is so very tiny that it can not be detected from the background noise, or from the planet's natural emergence from the last Ice Age, then no one would pay any attention to them at all, and the $ Billions in annual grant money to study the «problem» would quickly evaporate.

Bleaching should have been ongoing for millions of years, as background temperatures have risen and fallen.
