There is a growing concern of global warming effects worldwide, and steps have been undertaken to counter these effects. Some of the evidence of global warming and climate change is the increase of temperature, sea level rise, and lessened snow cover in Northern Hemisphere.

The increase in temperature is more likely to cause an increase in precipitation, though the effects on storm remains unclear. Extratropical storm is partly dependent on temperature gradient, which is said to dissipate in northern hemisphere as polar regions continue to become warmer.

The southern Arctic region in northern hemisphere experienced a rise in temperature from one degree Celsius to 3 degrees Celsius within the last 50 years. Alaska, Russia, and Canada are currently experiencing the first permafrost melting. It may cause a disruption of ecosystems, and the increased amount of bacterial activity in soils may make it a source of carbon instead of being carbon sinks.

A study regarding changes to the permafrost in eastern Siberia states that it is slowly disappearing around the southern regions, which led to Siberia losing almost 11% of about 11,000 lakes since the year of 1971. It is also noted that while this is occurring, western Siberia is now at a stage when new lakes are created due to the melting of permafrost. Furthermore, the melting of permafrost will also lead to release of methane from the melting peat bogs.

Reports state that there was no tropical cyclone in South Atlantic Ocean before March 2004. However, on 28 March 2004, the very first Atlantic cyclone in the equator’s south hit Brazil. It has the wind speed of 144km/h, though some meteorologists dispute it to be a hurricane. For performance advice on ssd drives, check this out.
