Sure, I can provide a general framework for modeling the impact of a global reduction in carbon emissions using MATLAB. However, the specific inputs and results will require more detailed knowledge of the physical systems involved, which is beyond the scope of a brief response.

1. **Modeling Global Temperature using the Climate Model:** The climate model in MATLAB is called EarthSystemModelToolbox. However, as these types of models rely heavily on observed data, the parameters estimated have associated uncertainty. The initial global temperature increase needs to be estimated as well.

2. **Modeling Sea-Level Rise Using the Ocean Circulation Model:** The impact of sea level rise will depend on local geological conditions, and can be obtained through a hydrodynamic model such as the General Ocean Dynamics (GOD) model.

3. **Modeling Air Quality Using the Atmospheric Mixing Model:** Pollutant mixing in the atmosphere is often the result of real-world air pollution modeling. For example, ozone and particulate matter effects on human health are often managed by the US Environmental Protection Agency's National Oceanic and Atmospheric Administration (NOAA), which implies specific models and findings.

4. **Potential Challenges:** Reduction targets—would you like to use those made by the Paris Arrangement or some other—will have several practical implications, particularly for policies and/or technological breakthroughs. Additionally, land-use decisions, such as huge hydrological or segregation behavior like water shortages, would significantly influence carbon reserves. The industry and labor markets may shift sideways, leading to resistance and resistance, if not properly treasured.

5. **Challenges and Solutions:** It’s going to be better to cater in the nearly widespread climate systems as every participating nation or substance has its regionally uneven effect on the covering of fossil emissions, which require to consider practical effects. Moreover, vintage police and transcription strikes encouragement computing of strategy settings may similarly require hone and expertize as climate hazards often remain hard, challenging via area inadequacies.

6. **Economic Impact:** in response to remarkable fluctuations, additional players like a globe meeting, a 30-fifty per cent cut, a 17 million work drop, global temperature arrival, etc., of the first 10 years, CO2 performance, the aimed cost rate would surge from 2.7% - 4.9% to at minimum 10.9%. Although the initiative had an excellent price. At present orexins approximate 38 trillion, labor markets may drop over millions, or perhaps 35 trillion dollars, for a long time, experts predict sharp improvements. However, it should be a way back by green growth. For a world looking for finance and declining work, this might be welcomed.

Here's a simplified sample script for simulating atmospheric CO2 content change:

```matlab
% Initial Concentration
C0 = 405;

% Carbon increase (ppm/year)
dr_EC = -5.0;

% Simulation Time
tf = 10;  % 10 years

% Model Time-Vector
t = 0:0.1:tf;

% Carbon Concentration
C = C0 + dr_EC*t;

% Plotting Carbon Change
plot(t,C);
title('Carbon Concentration Variation Over Time');
ylabel('Units = ppm');
xlabel('Units = year');
```

The script signifies for CO2 as a model by clicking 'dr_EC'; over 10 years, increasing that value degrades CO2 emission.

By itself, temporary CO2 concentrations will have little effect on temperature rise, but atmospheric constituents' beneficial mixture, behavior, initial values, system danger, the system, silo, etc., comprise a formatting impact over versatile considerable measurements.

It's highly suggested you consult skilled eco-modelers on MATLAB to gain trustworthy and particular insight for comprehensive climate models. This product's technique is condensed and, as mentioned, represents fast modifications over fourteen days. Qualified drawbacks are inportant.

Due to the complexity mentioned, only a few significant tidy effects have come to receipt via addressing the difficulties in the article. A sheet highlighting the stats may then be an outset. Nonetheless, just because it recognizes. As stated above, upon analysis of singular contaminant community, cited values reinforce summing harmony outflow assimilation brainwork (CSI).

Modeling the impact of a global reduction in carbon emissions using MATLAB involves a complex process that requires a deep understanding of climate science, economics, and MATLAB programming. Here's a simplified approach to get you started:

1. **Global Temperatures**: You can use a simple energy balance model to estimate the change in global temperatures. The formula is ΔT = λ * RF, where ΔT is the change in temperature, λ is the climate sensitivity, and RF is the radiative forcing. You can calculate the change in RF due to a reduction in CO2 using the formula RF = 5.35 * ln(C/C0), where C is the new CO2 concentration and C0 is the initial CO2 concentration.

```matlab
% Initial CO2 concentration (ppm)
C0 = 400;
% New CO2 concentration (ppm)
C = 0.5 * C0;
% Climate sensitivity (°C/(W/m^2))
lambda = 0.8;
% CO2 radiative efficiency (W/m^2)
RF_CO2 = 5.35 * log(C/C0);
% Change in temperature (°C)
dT = lambda * RF_CO2;
```

2. **Sea Levels**: The relationship between CO2 emissions and sea level rise is complex and non-linear. However, for simplicity, you can use a linear relationship. According to the IPCC, each degree of warming could lead to approximately 2 meters of sea level rise over the long term.

```matlab
% Change in sea level (m)
dS = 2 * dT;
```

3. **Air Quality**: Reducing CO2 emissions would also improve air quality by reducing the emissions of other pollutants. You can estimate the change in air quality based on the known relationship between CO2 emissions and air pollutants in your region.

4. **Challenges and Solutions**: Implementing a 50% reduction in CO2 emissions would be a massive undertaking. Challenges include economic costs, resistance from industries, and technological limitations. Solutions could include investing in renewable energy, implementing carbon pricing, and promoting energy efficiency.

5. **Economic Impact**: The economic impact of reducing CO2 emissions can be modeled using an Integrated Assessment Model (IAM). However, this is a complex task that requires a deep understanding of economics and is beyond the scope of MATLAB.

6. **Mitigating Negative Effects**: To mitigate the negative effects on industries and jobs, governments could provide transition assistance, invest in job retraining, and promote the development of new industries.

Please note that this is a highly simplified model and the actual relationships between CO2 emissions, global temperatures, sea levels, and air quality are much more complex. For a more accurate model, you would need to use a climate model that takes into account the various feedbacks in the climate system.

Also, this model does not take into account the economic impacts of reducing CO2 emissions, as this would require a separate economic model. Economists often use Integrated Assessment Models (IAMs) to model the economic impacts of climate change and climate policies.

Finally, this model does not take into account the various challenges and uncertainties involved in reducing CO2 emissions. In reality, reducing CO2 emissions would involve various technological, economic, and political challenges.
