CO₂ vs temperature from Antarctic ice cores

# data[].attributes.body
Why is there a correlation?

There is a correlation in the graph, as the CO2 levels increase, the temperature of the ice cores also rises. Although the graph does not show the same changes in CO2 levels over the years, there is an evident correlation between CO2 and the temperature of Antarctic ice cores.

Why doesn’t this prove causation?

It doesn't prove causation since the changes in CO2 did not directly affect the Antarctic ice core temperatures; we can only see a relationship associated with the increase in CO2 and the increase in Antarctic ice core temperatures, which is a correlation.

Distinguish: Because through the causations, we can identify a direct threat in nature, while with correlation, we can identify a trend for the changes in nature.

Emissions provoked by humans contribute to the greenhouse effect. The major anthropogenic greenhouse gases are:

CO2

Methane

Nitrous Oxide

Varios synthetic chemicals

# data[].attributes.body
CO2 is caused primarily by burning fossil fuels, cement production and deforestation

# data[].attributes.body
If these anthropogenic greenhouse gases continue, the planet will keep warming up, which will lead to glaciers melting. This harms the whole world.

A positive feedback cycle occurs when a change in the body triggers an even greater change in the same direction. It drives a process to keep going instead of stopping. Positive feedback is less common than negative feedback and usually ends when the goal is reached.

During childbirth, pressure from the baby’s head causes the release of oxytocin, which makes contractions stronger. This leads to even more oxytocin being released until the baby is born.

A positive feedback cycle occurs in the body in damaging way, it could lead to a serious problem in the way the body already has been affectd.

A critical threshold in the climate system where a small change could lead to a greater change in all the boreal forest ecosystems.

# data[].attributes.body
In alaska there were many wildfires which were caused due to warmer temperatures in the zone. The forest are turning into grassland due to the fires, which means they cant go back to how they originally were.

# data[].attributes.body
We need to be conscious of how everything is connected. Due to the warmer temperatures, the effect of global warming, many forests are changing and being damaged, which does not allow them to go back to how they were affecting the ecosystem had once.

Due to the risng temperatures and increasing solar radiation, sea and landfast ice melt which leads to a decline in both he thickness and extent of ice.

# data[].attributes.body
In the Arctic, warmer weather is melting sea and landfast ice. This hurts animals like polar bears and affects hunting. It also causes coastal erosion and stronger waves. Less ice makes the Arctic heat up even faster.

# data[].attributes.body
If we don't do anything to prevent or diminish global warming, ice will continue melting and it will cause sea levels to rise, which affects coast cities and low lying areas.

Ocean currents are continuous directional movements of ocean water driven by gravity, wind and differences in water density. Upwelling is a type of ocean currents that bring cold nutrient-rich water from the deep of the ocean to the surface.

# data[].attributes.body
A real-world example of ocean currents and upwelling is along the coast of Peru. Cold water rises from the deep ocean, bringing nutrients to the surface. This helps fish like anchovies grow in large numbers. When upwelling slows down, fish numbers drop, hurting local fishing communities.

# data[].attributes.body
Ocean currents specially upwelling, have a significant impact on marine ecosystems and the global climate. Since the movement of cold, nutrients reach deep water to the surface and support thriving ecosystems and fisheries.

Range shifts of species happen when animals or plants move to new areas because their old habitats become too hot, cold, dry, or otherwise unsuitable—often due to climate change. They usually move toward the poles or higher up mountains where conditions are better.

# data[].attributes.body
A real-world example of a range shift is the butterfly species Edith’s checkerspot. It has been moving north and to higher elevations in North America because rising temperatures made its old habitats too warm for survival.

# data[].attributes.body
The butterfly’s range shift shows how climate change forces animals to move to survive. It reminds me how important it is to protect nature before more species are lost.

Coral reef collapse happens when corals die off in large numbers, usually due to rising ocean temperatures, pollution, or acidification. This destroys the reef ecosystem and harms the many species that depend on it.

# data[].attributes.body
A real-world example is the Great Barrier Reef in Australia. Large parts of it have suffered from coral bleaching and collapse due to rising sea temperatures and climate change.

# data[].attributes.body
The collapse of the Great Barrier Reef shows how climate change harms even the most beautiful ecosystems. It reminds me how urgent it is to protect our planet before more are lost.

Carbon sequestration is the process of storing carbon to reduce climate change. Natural ways include rewilding, where forests are restored to absorb CO₂, and protecting peatlands, which trap carbon in wet soil for years.

# data[].attributes.body
A real-world example is the restoration of peatlands in the UK. By rewetting drained peatlands, they store more carbon and help fight climate change.

# data[].attributes.body
Restoring peatlands shows how nature can help fight climate change if we protect it. It makes me hope we can use more natural solutions to keep our planet healthy.
