Global Warming

Major forces impacting global producers in trading include shifts in market demand, geopolitical instability, currency fluctuations, trade policies, and technological advancements. These factors can affect production costs, competitiveness, market access, and overall business performance for global producers like Electra.

Water vapor is the most abundant greenhouse gas in the atmosphere, accounting for somewhere between 1/2 and 2/3 of the total effect. CO2 is the next most abundant.

By definition, global warming can not be "in north America". Global means "world-wide" and America is but part of the world. However, the United States can and will experience the impact of global warming. During the Winter Olympic Games, Canada was in the embarrassing position of having to truck in snow from hundreds of kilometres away: that is the public face of global warming.

Some will scoff, but global warming can result in the US experiencing localised episodes of extreme cold, simply because of changing wind patterns from the Arctic region. Some also scoff when told that the recent extremes of hurricane and tornado activity could well be the result of global warming.

We do know that the average global temperature is increasing. Average temperatures in the United States will also inevitably increase. However, those are averages and there will be occasional localised extremes of either heat or cold.

Carbon dioxide

mechanical energy

Most nations have played some part in global warming and climate change. But, all nations with modern societies with automobiles and that use fossil fuel for heat or transportation contribute to climate change and are responsible for it to some degree. Whether they're responsible for it or not they'll suffer from it.

The warm temperature inside the greenhouse can cause the air molecules inside the balloon to expand, increasing the pressure inside. This can lead to the balloon either expanding in size or potentially bursting.

• Carbon dioxide (CO2) is called a "well-mixed" gas. It gradually spreads out all round the world, largely because it remains in the atmosphere for a long time.
• It adds to the growing levels of greenhouse gases (CO2 and methane) that are causing the enhanced greenhouse effect.
• It traps infrared heat rising from the surface of the earth (which has been warmed by ultraviolet radiation from the sun).
• It causes global warming, which is causing climate change.

If we define short-term climate change as limited to around one year, then El Nino and La Nina are the factors that affect (and effect) it.

Long-term climate change happens over thousands of years, because of many factors like the strength of the sun, the tilt of our planet, the movement of the earth's orbit.

Long-term climate change is also happening very quickly now because of global warming, but the effects will last a long time.

Natural climate variability, such as El Niño and La Niña events, volcanic eruptions releasing aerosols into the atmosphere, and fluctuations in solar radiation can cause the average global surface temperature to rise and fall from year to year. Additionally, human activities, such as greenhouse gas emissions and land-use changes, can contribute to long-term warming trends.

The earth has natural carbon and water cycles that support the greenhouse effect in the atmosphere. The earth's surface it heated by radiation from the sun, in normal conditions these radiations are reflected back. Carbon dioxide and other greenhouse gases trap this radiation and prevent much of it from escaping into space. This the natural greenhouse effect which keeps the earth comfortably warm for us. It is as old as life itself.

Two hundred years ago man started burning fossil fuels for industry, transport and generating electricity. This coal and oil contained carbon that had laid underground for millions of years. Burning it released all the extra carbon dioxide to add to the greenhouse gases in the atmosphere.

At the same time we also began seriously cutting down our great forests. Forests absorb carbon from the atmosphere and store it in the wood. About half the weight of a tree is carbon.

Both these things mean there is more carbon dioxide in the atmosphere. This CO2 is trapping more of the sun's heat, and thus there is a rise in temperature of the earth and we call it global warning.

Ice caps remain frozen throughout the year at latitudes above 60 degrees north and south, particularly within the Arctic and Antarctic circles. These regions experience extreme cold temperatures that prevent thawing of the ice caps.

Carbon dioxide (and other gases) creates a "blanket" around the earth trapping heat in the atmosphere. If these "greenhouse" gases were not there some of the heat would escape from the earth's atmosphere

Carbon dioxide is transparent to visible light but opaque to infrared light (i.e. heat).

When sunlight passes through the atmosphere and heats the surface of the earth the earth radiates infrared light. At low levels of carbon dioxide most of this infrared escapes to space, cooling the earth; but at high levels of carbon dioxide most of this infrared is reflected back down to the surface of the earth, keeping it hot.

Human activities, such as burning fossil fuels and deforestation, release greenhouse gases into the atmosphere, which contribute to climate change by trapping heat and causing global temperatures to rise. These activities also result in other pollutants that can alter weather patterns and impact climate systems.

Growing vegetation, like trees, plants and crops, removes carbon dioxide from the atmosphere. The other natural method is the carbon cycle, which moves carbon in and out of the atmosphere, in and out of the oceans, and in and out of the land.

Carbon dioxide levels increased by approximately 15-20 parts per million (ppm) from 1980 to 2000. This is based on data from the Mauna Loa Observatory, one of the longest-running sites measuring atmospheric CO2 concentrations.

Modernization has affected global religions by challenging traditional practices and beliefs, leading to changes in religious interpretations and expressions to adapt to evolving societal norms. It has also facilitated the spread of religious ideas, beliefs, and practices through technology and global communication networks, making religion more accessible to a wider audience. Additionally, modernization has influenced the way religious institutions are organized and operate, leading to shifts in power dynamics and hierarchies within religious communities.

• The sun's heat (ultraviolet radiation) warms the surface of the earth.
• Heat rises (infrared radiation) rises from the warm earth.
• Much of this heat is captured by greenhouse gases which become warm.
• This warmth makes the surrounding atmosphere warm.
• It also warms the surface of the earth even further.

No. Hurricanes can cause storm surges, especially if combined with high tides, which can overwhelm levees and flood coastal areas temporarily. They do not raise global sea levels. The melting of ice caps and glaciers and the expansion of the warming oceans will raise sea levels.

When an animal's habitat changes, then the animal has to adapt to the new habitat, or move to a more suitable living place. This applies to all animals, including humans.

In the northern hemisphere mosquitoes are moving south following warmer weather. Polar bears are spending more time on land.

In Africa famines and crop failures are forcing people to move. In the South Pacific the President of the low-lying islands of Kiribati has bought land in Fiji as the rising sea levels threaten his country.

There may be many climate refugees, seeking refuge.

The term "ozone layer" can be misleading because it implies that ozone exists in a distinct, separate layer in the atmosphere. In reality, ozone is present throughout the stratosphere in varying concentrations. So, it's more accurate to think of the ozone layer as a region of the stratosphere with higher concentrations of ozone rather than a single, uniform layer.
