What is Southern Hemisphere and Northern Hemisphere? What is located in the northern hemisphere? Which countries are in northern hemisphere?

What is the most southern country in the world? Is Mexico in the Southern Hemisphere? That is to say, global sea ice is decreasing even as Antarctic sea ice is increasing slightly. Unlike the Arctic, where the downward trend is consistent in all sectors, in all months, and in all seasons, the Antarctic picture is more complex. Although sea ice cover expanded in most of the Southern Ocean between and , it decreased substantially in the Bellingshausen and Amundsen seas.

These two seas are close to the Antarctic Peninsula, a region that has warmed significantly in recent decades. The variability in Antarctic sea ice patterns in different sectors and from year to year makes it difficult to predict how Antarctic ice could change as greenhouse gases continue to warm the Earth. Climate models predict that Antarctic sea ice will respond more slowly than Arctic sea ice, but as temperatures continue to rise, a long-term decline is expected.

Why do the negative trends in Arctic sea ice seem to be more important to climate scientists than the increase in Antarctic ice? Part of the reason is that the size of the increase is much smaller and slightly less certain than the Arctic trend. Another reason is that the complete summertime disappearance of Northern Hemisphere ice would be a dramatic departure from what has occurred throughout the satellite record and likely throughout recorded history. In the Antarctic, however, sea ice already melts almost completely each summer.

One reason may be that other atmospheric changes are softening the influence of global warming on Antarctica. For example, the ozone hole that develops over Antarctica each spring actually intensifies a vortex of winds that circles the South Pole.

The stronger this vortex becomes, the more isolated the Antarctic atmosphere becomes from the rest of the planet. In addition, ocean circulation around Antarctica behaves differently than it does in the Arctic.

One concern related to Antarctic sea ice loss is how the relationship between land and sea ice will change. Ice shelves partly rest on land and partly float, and sea ice is thought to stabilize the edges of these shelves. Because the Southern Hemisphere has significantly more ocean and less land, climates tend to be milder than similar latitudes in the Northern Hemisphere.

This is because water heats up and cools more slowly than land. Regarding land, the Southern Hemisphere contains all or a portion of five continents , including:. Also called an alpha predator or top predator. The two sides never confronted each other directly. The Earth is the only place in the known universe that supports life.

Also called East Antarctica. Also called the energy balance. Also called West Antarctica. National Aeronautics and Space Administration the U. Also called thermohaline circulation. Sea level is determined by measurements taken over a year cycle.

It includes snow and ice on land, ice caps, glaciers, permafrost, and sea ice. As the world warms due to increasing greenhouse gases being added to the atmosphere by humans, the snow and ice are melting. At sea, this exposes more of the dark ocean below the ice, and on land, the dark vegetation below.

These dark surfaces then absorb the solar radiation causing more melting. This creates a positive feedback loop, which exacerbates the impacts of climate change.

Sometimes these align with a natural geographic feature like a river to form a border or barrier between nations. Occasionally, two countries may contest where a particular border is drawn. These disputes might arise due to a natural resource both groups want, like in the case of Sudan and South Sudan, or in an attempt to gain more political power, as in the case of Pakistan and India in the Kashmir region.

Use these resources to explore more about political boundaries. The northern hemisphere experiences summer during the months of June, July, and August because it is tilted toward the sun and receives the most direct sunlight.

Inversely, summer for the southern hemisphere takes place during the months of December, January, and February because that is when it receives the most direct sunlight.
