The main factors contributing to sea level rise from climate change are the thermal expansion of seawater and the melting of land-based ice, such as glaciers and ice sheets. When the ocean absorbs heat from the atmosphere, the water molecules move faster and spread out, increasing the overall volume of the ocean. This thermal expansion is a significant contributor to sea level rise. Simultaneously, as glaciers and ice sheets melt due to rising global temperatures, the added water flows into the oceans, further increasing sea levels. Other contributing factors, though less significant than thermal expansion and ice melt, include changes in groundwater storage (where water is extracted from aquifers for human use, and this water eventually flows into the ocean), and changes in land water storage (such as reservoirs). The relative contribution of each factor varies regionally, but thermal expansion and ice melt are consistently the dominant drivers of global sea level rise.
Yo, so basically, the Earth's gettin' hotter, right? That makes the oceans expand 'cause warmer water takes up more space. Plus, all that ice meltin' adds more water to the mix. Boom, higher sea levels.

Understanding Confidence Levels in Statistics
A confidence level in statistics represents the probability that a population parameter falls within a calculated confidence interval. It's crucial for understanding the reliability of your estimations. Let's break down how to find it:
Define Your Confidence Interval: This interval estimates the range within which a population parameter (like the mean or proportion) likely lies. It's typically expressed as a percentage (e.g., 95%, 99%). The choice of confidence level depends on the context of your research and the desired level of certainty.
Determine Your Sample Data: You need a representative sample from the population you're studying. The larger the sample size, generally, the more accurate and narrower your confidence interval will be.
Calculate Your Sample Statistics: Calculate relevant statistics from your sample data. This often involves calculating the sample mean (average) and the standard deviation (a measure of data spread). For proportions, you calculate the sample proportion.
Select Your Significance Level (alpha): The significance level (alpha) is related to the confidence level. It's the probability of rejecting a true null hypothesis (a statement of no effect). It's calculated as 1 - confidence level. For example, a 95% confidence level has a 0.05 significance level (1 - 0.95 = 0.05).
Find the Critical Value: The critical value depends on your chosen confidence level, the type of test (one-tailed or two-tailed), and the degrees of freedom (related to sample size). You can usually look this up in a statistical table (like a t-table or z-table) or use statistical software.
Calculate the Margin of Error: The margin of error quantifies the uncertainty in your estimate. It's calculated by multiplying the critical value by the standard error (standard deviation/√sample size).
Construct Your Confidence Interval: Finally, construct your confidence interval by adding and subtracting the margin of error to your sample statistic. For example, for a mean, it's: Sample Mean ± Margin of Error.
Example: Let's say you have a 95% confidence interval for the average height of students. After calculations, you find your confidence interval to be (65 inches, 70 inches). This means you are 95% confident that the true average height of all students falls between 65 and 70 inches.
In summary, finding a confidence level is an iterative process involving selecting a desired level, collecting data, calculating statistics, determining critical values, and constructing a confidence interval. Statistical software can significantly simplify these calculations.
Simple Answer: The confidence level is the probability that your sample accurately reflects the true population parameter. It's usually expressed as a percentage (e.g., 95%). It's calculated using statistical methods involving sample data, standard deviation, critical values and margin of error.
