1 Toe spreaders that fit all of your toes are somewhat more helpful, as they re-align all of the toes in the foot. 2  They can provide relief for your sore foot in as little as 30 minutes. 3  If you can tolerate sleeping in them, theyâll relax the tendons in your foot and provide some comfort. This will provide some relief to the tendons in the upper mid-foot, which become sore form the stretching caused by the bunion. 2  Toe spreaders that fit all of your toes are somewhat more helpful, as they re-align all of the toes in the foot. 3  They can provide relief for your sore foot in as little as 30 minutes.
For at least the last 100 years, sea level has been rising at an average rate of about 1.8 mm (0.1 in) per year. Most of this rise can be attributed to the increase in temperature of the sea and the resulting slight thermal expansion of the upper 500 metres (1,640 feet) of sea water.recise determination of a mean sea level is a difficult problem because of the many factors that affect sea level. Sea level varies quite a lot on several scales of time and distance.
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.
