...global temperatures were at least as high, or higher than they are now, even though CO2 concentrations in the atmosphere were much lower then. The study also indicates that the sea level was changing rapidly around this time period, rising as much as 1 m the century before, as ice melted, and then falling afterward at around the same speed, as ice began to freeze once more. Rather than forming steadily and melting steadily, the process of glacier freezing and receding may be more more unstable, reflected in sudden rising and falling of the sea level. "It's fair...
...reason that sea levels may have been higher 81,000 years ago than today is that the Earth was receiving stronger solar radiation at that time. That would fit into what's known as the Milankovitch theory of ice-age cycles, which posits that the Earth's orbit around the sun and the planet's axial tilt wobble periodically, increasing or decreasing the amount of solar radiation hitting the planet's surface. "The sea-level high may be considered an exception to the 100,000-year cycle, in which high summer sunlight caused the ice sheets to melt," writes...
...course, Dorale's sea-level measurements are just one point of data that will need to be confirmed by other scientists - along with his own work, which will continue in Mallorca. And because the Earth itself changes shape over tens of thousands of years, responding to the shift of ice and water on its surface, it's impossible to infer the entire geological story from one location at one point of time...
...biggest gaps in climate science is our understanding of how the major ice sheets of Greenland and Antarctica will respond to warming temperatures. The science is so foggy that the Intergovernmental Panel on Climate Change - which recently came under attack for hyping the impacts of global warming - has refrained from estimating how fast those ice sheets could melt and contribute to sea level rise. Dorale's paper suggests the possibility that ice sheets may respond much more dynamically to changes in temperature, forming and melting at rates that are quicker than previously thought. "There might be a feedback with regards...
