Sea levels are currently rising about 3 mm a year. In 20 years sea levels have risen about 60 mm, which is 6 cm (2.36 inches).
0.8 degrees Celsius, since 1850. 1850 was a known low temp referred to as the mini ice age. The total warming started roughly 10,200 years ago and is, in total, about 11 degrees C. 0.6 of the current warming occurred before World War 2. The temperature dropped for a few decades in the 1970's despite increasing use of fuel. 2010 tied with 2005 as the warmest years on record. The ten hottest years have all happened since 1998.
Earths core temperature is sustained by fissile materials slowly breaking down over time. This energy is dissipated to space and will eventually run out. Much like Mars, Earths core and mantle will become solid and Earth will lose its magnetic field. Earths surface temperature is a function of many variables. Among those variables are; The previously mentioned magnetic field limits solar radiation to the thermosphere, Greenhouse affects of diffuse materials in the atmosphere reflect heat back to the surface, And convective currents circulate heat between regions of different temperatures.

Since 1930 Ireland's average temperature has risen by 0.7° Celsius.Of the 15 warmest years in Ireland, ten have occurred since 1990.There is a trend of increased rainfall along the north and west coasts.
Sea levels are currently rising about 3 mm a year. In 20 years sea levels have risen about 60 mm, which is 6 cm (2.36 inches).
the external remparture of the earth is much lower than the temperature far beneath the earths surface
Mars. With an average surface temperature of -63 degrees Celsius, it is much colder than Earths average of +14 degrees Celsius - but it is the closest to it.
