Can Machine Learning Help Tackle Climate Change?

There has been plenty of discussion and debate within the scientific community on the efficiency and effectiveness of machine learning methods to enhance our understanding of global and local environment. Machine learning can allow for the use of probabilistic calculations and predictive models to be carried out and are great instruments for evaluating the advantages and the costs of our actions at present. It’s helpful for people involved in research on climate change to be aware of the strengths and weaknesses of current techniques for machine learning which leads to greater understanding and critique of published research findings and conclusions.

What is Machine Learning?

Machine learning is a part of the larger concept of Artificial Intelligence (AI), which is described in the 2004 research paperas “the science and technology of developing intelligent machines, specifically sophisticated computer software”. The exact nature of “intelligence is a subject of debate and, to be precise it is artificial in the sense that computer models are utilized for interpreting large data sets. Models are typically designed to support research that isn’t feasible or too laborious to conduct using conventional analysis.

The below diagram shows the way that popular machine learning terms are linked:

It is also crucial to comprehend the five key terms that follow:

  • The term “algorithm” refers to algorithmis an instruction set (in this instance, provided to computers) that converts input data into output data. For instance, it calculates your carbon footprint for an enterprise by analyzing variables such as the consumption of energy or fuel as well as manufacturing processes and offset efforts.
  • Models modelis the representation of algorithms of an entire complex system (such like climate, or economy). A model typically consists of many algorithms to tackle a complicated problem.
  • Structured Datais data that has been labeled and whose nature is already known such as temperature data. Classical machine learning typically utilizes structured data.
  • Unstructured datais data that is presented in raw form like images. Deep learning models are able to use both unstructured and structured data to develop natural visual recognition and language processing systems. But, they require higher capacities computational power than traditional machine learning techniques.
  • neural networksare among the top significant algorithms for machine learning. It is the program or model made up of several connected nodes. The nodes as well as the connections are crucial. Below is a basic sketch of how neural networks may be organized.

Each network receives inputs from the previous nodes or from data as well as one or more hidden layers (algorithms which can alter the input) as well as an output. If the algorithm of a node produces an output that is greater than the specified threshold and the output is activated. Every connection is assigned a weight in order to show how effective it is in predicting a general outcome. The connections that prove to be more reliable in predicting outcomes are given a greater weight. The less effective connections receive less weight, or even be removed.

Thus, through the repeated presentation of data and the comparison of predicted outputs the neural network is able to depict the system being modelled more precisely. If confidence is present of the models, they could use it on new data in which the answers aren’t clear and to hypothetical databases that could be created in the near future.

Methodologies for machine learning can be classified into three types of learning which are: Supervised, unsupervised, and reinforcement learning. They are summarized below and are categorized according to the kind of data utilized and the output desired:

  • The use of supervised educationis suitable in cases where the data are as well-studied (usually structured data) however the connection between them is not clear such as, for instance economic modeling.
  • Unsupervised Learningis used to extract insights from non-structured data that are that are not directly connected to the problem to be solved for example, images or sounds.
  • Reinforcement Learningis utilized to improve algorithms that are based on trial and error by the repeated presentation of data. The algorithms that can most effectively determine the correct answer are the most preferred.

What are the Data Requirements for Machine Learning Techniques?

The data requirements for various methods of machine learning differ depending on the needs of the model. The data set must be large enough to allow for the division into testing and training subsets. Training datasets are used in order to build the model while the testing dataset is used to evaluate the effectiveness that the algorithm has. Certain research may require a second validation data set. In general, data are split in a ratio of 70/30 between the testing and training sets. This can be performed in a variety of ways. It could be divided in a spatial manner (for instance, by region) as well as temporally (over various time intervals) or even classified by the various variables, such as the land cover.

3 Ways in Which Machine Learning Techniques Help Address Climate Change

1. Improved Data Analysis

Machine learning is a way to tackle climate change by analyzing data to identify pattern and patterns that aren’t visible to the naked eye or aren’t feasible for humans to track. In particular machines that learn enable the continuous and automatic monitoring of images of the world to spot the presence of landslides, wildfires and other visible signs by using image and pattern recognition. Reinforcement learning allows models to improve their accuracy in recognizing changes and dangers. They can be determined and assessed by an expert before being referred to the authority responsible to mitigate.

Other applications blend disparate data to make new discoveries or provide important information. For instance, deforestation and bleaching data from coral could be paired with meteorological data to better understand how they affect each other.

An even more abstract use is the analysis of preparedness and sentiment. This aims at understanding our thoughts and emotions about climate change as well as attitudes towards mitigation efforts. The data is typically taken from crowdsourcing strategies or social media.

When assessing the general sentiments and beliefs of communities in combating climate change, organizations and government agencies can improve services, such as disaster preparedness programs as well as locally-focused initiativesto enhance the living standards. Through comparing the views of various demographic groups the ability is to pinpoint areas of need for education, information and strategies for tackling the spread of misinformation.

2. Optimising Systems and Solutions

Machine learning can help tackle climate change by either improving or adapting systems that maximize resources, in accordance with the context of information provided by the machine. For instance, automated electricity gridsoptimise energy production by monitoring and forecasting the demand for energy and supply. Machine learning could make use of data from traffic patterns to predict the demand for electric cars that will charge next night. This could also be used to support local initiatives, like looking to minimize the heat island effect in urban areas by applying machine learning to improve urban planning by taking into account aspects like the infrastructure and the vegetation cover.

Another model is carbon sequestration modeling. This method assesses the amount of carbon is stored in various forms around the world. Machine learning models can be utilized to model carbon sequestration and the impact it has over time . This information can be used to create more efficient carbon-capturing systems.

3. Scenario Modelling and Planning

Another use for machine learning in the fight against climate change is prediction and simulation of future scenarios arising from anthropogenically-induced climate change. The most pressing applications of this is to model the frequency and the severity of extreme weather incidents. These include droughts, wildfires excessive rain, flooding, and landslides. This is accomplished by combining variables (for instance, temperature or rainfall) with the likelihood of a particular hazard to predict the intensity or frequency of that risk could alter depending on the scenarios of the future. Predictive models is also a way to evaluate the impact of various scenarios on ecosystems in terms of species-population modeling and also to consider the long-term effects of processes like how fast algae bleaching could change under different conditions of the environment.

What are the Benefits of Using Machine Learning to Tackle Climate Change?

The main benefit of using machine learning lies in the way that it permits us to simplify, categorize and formulate predictions using highly complex datasets. It is possible to analyse data on greater temporal and spatial scales to observe intricate processes, allowing global monitoring and mobilization. With regard to the future of development machine learning is an increasingly feasible method for data analysis, as the price in processing capacity and storage of data is reduced, due to the efficiency that cloud computing provides. In addition, the massive increase in the availability of data due to various resources like the Internet of Thingsand crowdsourcing techniquesallows for the expansion of machine learning methods to combat climate change.

What are the Limitations and Risks of Machine Learning?

The four limitations to machine-learning need to be recognized to ensure the accuracy of outputs from models:

1. Lack of Data

Machine learning is best when models are trained using many different scenarios, so that the impact of every variable can be assessed, that includes extreme and edge scenarios. Since high-quality satellite data is only available for a little less than sixty years, environmental machine-learning models are restricted to the last few decades. There aren’t any datasets from major interglacial periods that can be used to understand what the environmental changes could be in more extreme circumstances. Therefore, there is an opportunity that models trained on machine learning will fail to detect interactions and feedback loops in circumstances that aren’t the ones for which they have been trained.

This renders a number of machine-learning techniques based on the current data sources ineffective for making long-term predictions. If you are looking at the long-term effects of environmental change, it is important to consider that changes should be considered over a long period of time regardless of whether the media is focused on the immediate issues of the next 50 to 75 years. There are other situations in which the data are not available. For instance, as of 2022, only 25 percent of the ocean floor are global maps. Once this is achieved, the completed mapping could help improve management of fisheries as well as the conservation effort.

2. Errors, Bias and Incomplete Data

Although data collection methods are getting more precise and reliable due to the increase in automation and better quality measuring equipment However, there’s an number of mistakes that could occur. If they aren’t addressed these errors can undermine the conclusions made by machine learning models. Although this is possible to mitigate through comparisons with previous datasets or long-term averages, the chance of error isn’t completely preventable.

A different issue is the chance from the inherent bias in the method of data collection or the selection of the data used to train the model , or the environment in which data was gathered. In simple terms, machines only learn from the data they are provided and any other factors that are not part of those data sets will not be included in any model that is trained. While this isn’t always an issue but it is essential to incorporate this into any analysis of the data. One example is to highlight the effect of the Covid-19 pandemic the reduction in carbon dioxide emissions by 2020.

3. Comprehensibility

Machine learning can create extremely accurate models that are able to adapt to various data inputs and situations, however it may not provide equations or connections that can be viewed to be verified by an independent party. One of the concerns frequently voiced by researchers is the danger of using “black box” models of machine learningthat humans can’t comprehend.

Neural networks self-adapt abstract of reality that is driven by data Inputs and outputs are visible, but there might not be any inherent reasoning behind the neural network that could be examined critically. It is essentially accumulated knowledge gained through repeated observations. In this context is the case, is the model able to be reliable in the near future simply because it has proven to be correct before? Of course, this critique is aimed at many theories of science that are founded on analysis and not founded on fundamental concepts However, these theories typically have a simple logic that can be attributed a level of certainty or even risk could be given.

In the process, it becomes a regular demand that models of machine learning are easily interpreted. This creates an ethical, but limited model that relies on a restricted amount of variants. Understanding the advantages and drawbacks of black box models lets us compare and evaluate different algorithms for machine learning in a more proactive manner.

4. Energy Consumption

The final aspect to consider when applying machine learning methods to fight climate change is whether the outcomes eliminate any greenhouse gasesproduced from the analysis and storage of these massive datasets. As storage of data and computing power get optimized and the availability of renewable power grows, this will become less of a problem.

Will Machine Learning Help Tackle Climate Change?

The general consensus among earth and climate experts is that models based on machine learning are effective instruments. When used properly machine learning has the possibility of making climate science more widely accessible and more applicable through industrialised study of the data. In addition, as machines possess no inherent biases particularly deep learning can provide conclusions that do not exist in other kinds of research. This could be due to the fact that the data isn’t suitable for traditional analysis , or because the conclusions are unexpected.

However, the majority black-box models do not work to provide us with accurate projections that are not within the range of data used to build the model. They can only be trained to produce outputs within the parameters of inputs utilized for training. Therefore they are often not equipped with information about errors or other elements that might be relevant. Thus, it is acknowledged that researchers are not able to describe the exact process by which neural networks arrive at their conclusions. This makes it risky to trust the network alone to make critical choices.

The resultant demand for more accessibility and transparency has resulted in an increasing publication of machine-learning models and code scripts, along with the data utilized. As the technology improves It is vital to base climate models upon the fundamental scientific processes that drive the earth’s natural cycles and systems. The models that are large-scale could include algorithms for machine learning, but they are likely to be an element of a bigger solution.

In a commercial sense one of the most promising platforms for combating climate change through machines learning, Microsoft’s AI for EarthProgramme. The program was introduced in 2017. is aiming to award 200 grant grants for research (totalling 50 million) to projects that use artificial intelligence to tackle the environmental impact. With Microsoft’s platforms and interface scientists and researchers can exchange results, data and findings directly providing greater visibility and quantifiable analysis. The aim is to establish an open space for collaboration to minimize the effects of climate change via connecting scientists. Others initiatives comprise Climate Change AI and the Climate Science for Service Partnership China and the Climate Science for Service Partnership China, both of which are collaborations in science that involve research institutions.
