Commonly with excessive incubation humidity the chicks will die having broken through the shell in one place (âpippedâ) either through weakness because of the lack of air to breathe in the shell or because of lack of space to turn and cut around the shell with their bill.
the tropics meanwhile are seeing extra sea level rise thanks to a strange gravitational effect as high latitude ice melts there is less mass at the poles to pull ocean water towards them instead the water slopes more towards the equator no matter which way you look at it the result is cause for concern
Over the past 5000 years the average rate of sea level rise was much less than 1 meter per millennium (1 mm/year), as shown by geologic markers on coastlines. In the past century tide gauges at coastal cities reveal a larger rate of sea level rise. The second chart below shows that sea level rose about 2 mm/year during 1920-2000. Satellites began to measure sea level precisely in 1993. Since then sea level has been rising about 3.2 mm/year. This rate is equal to just over one foot per century. The impact of such sea level change is substantial, yet the concern is that far greater sea level rise will occur this century if the major ice sheets disintegrate.
