1.1 The Urgency of Climate Change
Climate change is a global challenge that poses significant risks to the environment, economy, and society. It is primarily caused by the increased concentration of greenhouse gases (GHGs) in the atmosphere, which results from human activities such as burning fossil fuels, deforestation, and industrial processes. The consequences of climate change include more frequent and severe weather events, rising sea levels, loss of biodiversity, and negative impacts on human health.
Addressing climate change requires a multifaceted approach that includes reducing GHG emissions, adopting clean energy sources, and developing resilient infrastructure. AI has the potential to play a crucial role in each of these areas, offering innovative solutions and insights that can help accelerate the transition to a sustainable future.

The mathematical model for ARIMA is given by:
$$ yt = phi1y{t-1} + phi2y{t-2} + cdots + phipy{t-p} + heta1epsilon{t-1} + cdots + hetaqepsilon{t-q} + epsilont $$
where $yt$ is the dependent variable at time $t$, $phi1, phi2, ldots, phip$ are the autoregressive coefficients, $ heta1, heta2, ldots, hetaq$ are the moving average coefficients, and $epsilont$ is the error term at time $t$.
