🔍 Main Idea: The ocean has layers. How these layers mix (or don&#39;t mix) is affected by climate change, which can impact marine life, ocean currents, and even global warming!

<ul>
	<li>Stratification is the layering of the ocean based on density.</li>
	<li>Think of a Stratified Fruit Salad 🍎🍌🍇
	<ul>
		<li>Top Layer: Warm, light, less salty water.</li>
		<li>Bottom Layer: Cold, dense, salty water.</li>
	</ul>
	</li>
</ul>

<ul>
	<li>The layers mix due to currents, winds, and tides.</li>
	<li>Imagine pouring cream into hot coffee ☕ -&nbsp;It swirls and eventually mixes.</li>
	<li>The greater the difference in density, the harder to mix.</li>
	<li>If there&#39;s reduced mixing, the ocean is more stable.</li>
</ul>

<ul>
	<li>A hotter climate = more stable ocean.</li>
	<li>Recipe for a Stable Ocean 📜
	<ul>
		<li>Warm the surface water - it expands!</li>
		<li>Melt some ice - freshwater pours in, reducing saltiness.</li>
	</ul>
	</li>
	<li>More stability = less heat, oxygen, and CO₂ transfer to the deep ocean.</li>
</ul>

<ul>
	<li>Stratification boosts global warming 🌡
	<ul>
		<li>Warmer surface water absorbs less CO₂.</li>
		<li>Less CO₂ absorption = hotter atmosphere and oceans!</li>
	</ul>
	</li>
	<li>Downside? Warmer water = less oxygen = sad marine life 🐟😢.</li>
	<li>Remember those pretty coral reefs? They can bleach from warm waters! 🐚💔</li>
</ul>

<ul>
	<li>Top 100m of the ocean = the ultimate ocean rave!</li>
	<li>Why? Sunlight can only crash this party for the first 100m!</li>
	<li>Photosynthesis here lets carbon enter the food chain.🌱➡️🐠</li>
	<li>Leftover food &amp; waste might drop and mix with deeper waters.</li>
</ul>

<ul>
	<li>Deep ocean currents act like elevators.</li>
	<li>When they approach continents, they&#39;re forced up, causing upwelling of nutrients - basically ocean vitamins!</li>
	<li>These vitamins fuel surface marine life.</li>
	<li>But, weird weather patterns like El Ni&ntilde;o can hit the &quot;stop button&quot; on these elevators.</li>
</ul>

Have you heard of the El Ni&ntilde;o? It&#39;s like that unpredictable guest at a party. When El Ni&ntilde;o shows up, it decreases upwelling events. This means fewer nutrients for surface marine life, which can affect everything from the tiny plankton to the massive whales!

🐋 Dive deeper, ask questions, and remember - Our oceans are a living entity, affected by everything around, even things happening miles above in the atmosphere! 🌬🌊🌍
