Read the given passage and answer the following questions based on it.

Emissions of carbon dioxide and other greenhouse gases plunged 4.6 percent in 2020, as lockdowns in the first half of the year restricted global mobility and hampered economic activity. Many hoped that this would mark the beginning of a more permanent shift downwards in emissions. Emissions from the manufacturing and the energy sectors contributed the most to recent global increases based on updated information from the IMF’s Climate Change Indicators Dashboard —a joint effort among national and international statistical organizations to provide timely data to help monitor the transition to lower carbon use.

As greenhouse gas emissions from human activities increase, they build up in the atmosphere and warm the climate, leading to many other changes around the world —in the atmosphere, on land, and in the oceans. While total emissions have climbed significantly above pre-pandemic levels, increases from transportation and households were more muted last year as the pandemic weighed on global mobility. This was particularly evident with the emergence of the omicron variant in the fourth quarter of last year. The public health policy measures in many countries drove down the emissions of households and of the electricity sector.

It will be important to monitor the emissions of both of these sectors as economies fully reopen in the context of historically high fossil fuel-based energy prices. The Intergovernmental Panel on Climate Change has said that, in the scenarios they assessed, limiting atmospheric warming to the key level of around 1.5 degrees Celsius requires global greenhouse gas emissions to peak by 2025 at the latest, emphasizing that achieving this milestone is a crucial step towards controlling the severity of climate change. The new data from the climate dashboard underscore what some scientists have warned: time is running out, and we must urgently bend the emissions curve to achieve the necessary reductions to limit atmospheric warming.

What is the overarching message conveyed by the passage regarding greenhouse gas emissions and climate change?

The correct answer is: "Urgent action is needed to reduce emissions and limit atmospheric warming."

To arrive at this answer, let us carefully analyze the passage paragraph by paragraph and identify the central theme the author is building towards.

Step 1 – Understanding the Opening Context
The passage begins by noting that greenhouse gas emissions dropped by 4.6% in 2020 due to pandemic-related lockdowns. Many saw this as a hopeful sign — a potential turning point toward lower emissions. However, this hope is immediately contextualized: the drop was temporary, not structural. Emissions from manufacturing and energy sectors continued to be the primary drivers of global increases. This sets up a contrast between short-term relief and long-term danger.

Step 2 – Identifying the Core Problem
The second paragraph explains that as human activities increase greenhouse gas emissions, these gases accumulate in the atmosphere, warming the climate and triggering widespread changes — in the atmosphere, on land, and in the oceans. Crucially, the passage states that "total emissions have climbed significantly above pre-pandemic levels." This confirms that the temporary dip during the pandemic did not represent a lasting change. The situation has worsened again.

Step 3 – Recognizing the Scientific Warning
The third paragraph introduces the Intergovernmental Panel on Climate Change (IPCC), which states clearly that limiting warming to 1.5 degrees Celsius requires global greenhouse gas emissions to peak by 2025 at the latest. This is a firm deadline, and the passage emphasizes it as a "crucial step towards controlling the severity of climate change."

Step 4 – The Concluding Urgency
The passage ends with its most powerful message: "time is running out, and we must urgently bend the emissions curve to achieve the necessary reductions to limit atmospheric warming." The word "urgently" is the author's deliberate signal — this is not a distant problem but an immediate crisis requiring rapid response.

Step 5 – Evaluating the Options
Now let us check why the other options are incorrect:

• "The world is on track to achieve the necessary reductions" — Incorrect. The passage explicitly warns the opposite: emissions are rising above pre-pandemic levels, and time is running out.

• "The Climate Change Indicators Dashboard is the sole solution" — Incorrect. The dashboard is described as a data-monitoring tool, not a solution in itself.

• "Greenhouse gas emissions have no significant impact on climate" — Incorrect. The entire passage is built around the enormous impact emissions have on climate change.

• "Economic growth is more important than addressing climate change" — Incorrect. The passage does not make this claim; instead, it treats climate action as paramount.

Conclusion
Every paragraph of the passage builds toward a single, unified message: despite some temporary reductions during the pandemic, greenhouse gas emissions are back on the rise, scientific bodies have set a critical 2025 deadline, and we are running out of time. The overarching message is therefore unmistakably clear — urgent action is needed to reduce emissions and limit atmospheric warming.
