Climate and us

In the Trulock Bay area of Pine Bluff, Arkansas, June 6,2019. Areas along the Arkansas River saw record-setting flooding caused by heavy rain. As global temperatures continue to rise Arkansas is expected to experience more frequent and intense flooding.

The increase in global greenhouse gas emissions, which traps heat in the atmosphere, is causing temperature to rise. With higher temperatures, more water evaporates from sea and land and the atmosphere holds more water vapor. This in turn increases the chance of more intense rainstorms and the chance of flooding.

How does climate change lead to flooding? Below is the references.

1.Heavier Precipitation

A warmer atmosphere holds and subsequently dumps more water. Due to climate change, the probability of rainfall is at least 40% higher and the intensity is at least 10% higher. Of course, heavier rainfall does not automatically lead to floods, but it increases the potential for them. And even moderate amounts of rainfall can cause serious damage, particularly in places where urban flooding is on the rise.

2.More-Frequent Hurricanes
Climate change is increasing the frequency of our strongest storms. In the Atlantic basin, an 80 percent increase in the frequency of category 4 and 5 hurricanes (the most destructive) is expected over the next 80 years. And stronger storms bring greater rains.

Observation:

Date-December 18, 2019

Air temperature-2 degree

Wind direction- North East

Wind speed-4.74 knots

Precipitation-drizzle

Dew point –  6 degree

Cloud type- Nimbostratus

Cloud cover-full

Lower air pressure

 

 

 

 

 

Map 1: There is lot of low pressure circling around which means that there will be lots of precipitation and clouds forming.

Map 4:More low pressure so there is more rain that is heading towards us.

 

Prediction:

From the data collected on the meteorological map, we see a swirling weather pattern centered on the low-pressure area. We think this will cause more clouds to form over us and cause precipitation, and the cold front in the vortex may lower the temperature a little bit.

First, we noticed that the climate seemed to be increasing, but they were not increasing dramatically. It was observed that the climate in the tropical seemed to be increasing during the time period shown, with precipitation fluctuating but seems to remain near the same starting average.

During the time period shown, I noticed that the climate in the dry regions was fluctuating and precipitation was decreasing. The climate in the mild temperate zone is increasing, and precipitation is also increasing. Although they are not drastic changes.

Looking at the snow region the temperature is increasing, and precipitation is also greatly increasing. Finally, observing the polar region, averages seem to have a pattern to them through each period of time, the precipitation is increasing and within the last two time periods it has significantly increased.

Conclusion:From our observations we notice more climate change in the colder regions, as well as, the regions with precipitation increased.  Precipitation is usually increased in the snow and polar regions more significantly then the other regions. Therefore, the low temperature zones will experience more rainfall due to the increasing temperature. However, the high temperature zones stay around the average temperature, but the rain is increasing.

Weather Reading Day 4

Observation:

Date-December 17, 2019

Air pressure-1018.0 mb

Air temperature-2 degree

Wind direction- North

Wind speed-10 knots

Precipitation-rain shower

Dew point – -6 degree

Cloud type- Nimbostratus

Cloud cover-full

Lower air preesure

 

 

 

 

 

 

 

We predict that the cold regions in our south will cool down tomorrow. And continue the amount of precipitation and clouds we see, wind will be bigger tomorrow.

We predict that there will be a more rain, and more wind tomorrow and because there is a high pressure zone moving up which will cause rain.

Weather Reading Day2

Observation:

Date-December 13, 2019

Air pressure-1017.0 mb

Air temperature-12 degree

Wind direction- East south

Wind speed-3.7 knots

Precipitation-drizzle

Dew point – 6 degree

Cloud type-Nimbostratus

Cloud cover-full

Higher air pressure than yesterday

 

 

 

 

 

 

 

We predict that there will be a cloudy day because the low pressure zone isn’t getting close enough to cause rain,and little wind tomorrow.

Fishing

species:Sockeye Salmon

According to information I got from Ocean Wise, Sockeye Salmon is mostly wild, and we should avoid catching Gillnet, Purse Seine and Troll varieties in the US, Washington, Oregon and California regions. In these areas, hatchery fish are mixed with wild salmon populations and are likely to capture natural salmon that are classified as endangered species. Therefore, in order to prevent the extinction of endangered species in the area, these fish should be resisted.

When fish are farmed, the fish is very dense, so the growth environment is not good and the fish is prone to illness. And because of the limited space available, excreta does not disperse in time, so nearly a quarter of fish can quickly spread fish disease. These fish are cultured in the process of interacting with wild fish, spreading the disease to wild species, infecting most of the wild fish and killing them. If this continues, it may kill all our fish: farmed and wild, so I think farmed fish are not sustainable.

The advantage of farmed fish is that it provides a guaranteed “harvest” for fish farmers and they can control the variety and yield obtained, thus reducing the price of fish. I think that the way to make the aquaculture sustainable is to raise the fish to the young age and then stock it in nature so that the fish can be more dispersed, the likelihood of disease is greatly reduced, and it will be more natural. When the fish is back, the fishermen can catch them with the big net, so that we can put more fish back into the ecosystem, which can effectively avoid the occurrence and spread of fish diseases.

How sustainable is BC’s Forestry Industry?

Benefits:

Clear Cutting
– Efficient for harvesting and replanting trees
– Financially sound
– Increased water flow
– Increased farm land
Silviculture
– Less expensive
– Easy and efficient operations
– Avoided damage to regeneration
Selective Logging
– Allows ecosystems to support more wildlife than clear cutting
– Allows forests to retain resistance to disease and pests.
– Reduced ecological damage

Drawbacks:

Clear Cutting
– Negative impacts on nature, wildlife, habitats and plant loss.
– Loss of 1000 year old forests.

Silviculture
– Exposure to erosion
– Takes away habitats for many animals
Selective Logging
– Takes away strong trees in the forest leaving the weaker trees.
– Difficult regrowth
– Harmful to other trees

Clearcutting is financially efficient, giving consistent and high rates of return for companies, provides more farmland for it cuts down all trees in an area, giving farmers more job opportunities. Although this practice has a significant and harmful effect on plants and wildlife in a region. The most significant impact is the destruction of plant life and animal habitat. Impacts on the food chain can cause loss of species and threats to ecosystems. The forest sector has long been a cornerstone of economic activity and continues to be the foundation of B.C.′s economy. Although its significance has declined as the economy has matured and diversified over the past few decades, the forest remains important. In 2018, the forest sector was responsible for 32% ($14.9 billion) of B.C.’s total exports; the sector is the primary employer in many parts of the province. Forestry-related activities directly support over 7,000 businesses and employ more than 50,000 people. That data proves that the BC forestry industry is relatively sustainable. However, sustainability for the forestry industry would mean ‘balance’, to balance out the economy and the environment. If we try to maintain the environment and the economy, it will be difficult to balance. Economic sustainability can mean destroyed forests, but the sustainability of ecosystems will affect manufacturers and trade with different countries.

I think the forestry industry in BC is sustainable. The government is also deforesting and rebuilding trees. Although it takes time, it can ensure a certain balance. If we accelerate the deforestation, the reconstruction and regeneration of trees cannot keep up with the rate of deforestation, then it is likely that the forestry industry will become unsustainable.
