What is the main effect of climate change in the Mekong Delta Vietnam?

Across the LMB, the effects of climate change are obvious. Rising temperatures and changes in the intensity of rainfall, river flow, floods, and droughts are destroying homes, infrastructure, crops and fisheries. As a result, vulnerable communities are faced with food shortages and diminished livelihoods.

What are 4 ways the Earth is being affected by climate change?

Increased heat, drought and insect outbreaks, all linked to climate change, have increased wildfires. Declining water supplies, reduced agricultural yields, health impacts in cities due to heat, and flooding and erosion in coastal areas are additional concerns.

How does the sea level tell us that the climate is getting warmer?

More glaciers are melting into the ocean, and the global sea level is rising. Sea level rise is another clue that tells us Earth’s climate is getting warmer. As the ocean gets warmer, the water actually expands! Scientists have observed that the sea level has risen 7 inches in the last 100 years.

What is causing environmental issues along the Mekong River?

The Mekong River ecosystem is on the verge of irreversible collapse due to the accumulative effects of climate change and increased numbers of upstream dams as well as other human-made activities such as deforestation, sand mining, extensive irrigation for agriculture and wetland conversion.

How is the greenhouse effect caused?

greenhouse effect, a warming of Earth’s surface and troposphere (the lowest layer of the atmosphere) caused by the presence of water vapour, carbon dioxide, methane, and certain other gases in the air. Of those gases, known as greenhouse gases, water vapour has the largest effect.

How does climate change affect the sea?

As greenhouse gases trap more energy from the sun, the oceans are absorbing more heat, resulting in an increase in sea surface temperatures and rising sea level. Increased ocean acidity makes it more difficult for certain organisms, such as corals and shellfish, to build their skeletons and shells.

How has climate change affect sea levels?

A warming climate can cause seawater to expand and ice over land to melt, both of which can cause a rise in sea level. The second mechanism is the melting of ice over land, which then adds water to the ocean.

What kinds of things could decrease Earth’s temperature?

Clouds reflect sunlight and reduce the amount of energy that reaches the Earth’s surface to warm it. If the amount of solar warming decreases, then the temperature of the Earth would decrease. In that case, the effect of adding more water vapor would be cooling rather than warming.
