This is an outstanding time in the Metropolitan Office:

A groundbreaking study shows that by the end of the century, North Atlantic oscillations (NAOs) may reach unprecedentedly large scales, resulting in serious impacts such as increased flooding and storm damage in Northern and Northern Europe.
this Nao It is a large-scale atmospheric pressure saw in the North Atlantic and is the main driver of winter weather patterns in the UK, Western Europe and the eastern United States. It is measured by the gradient between the Azores high pressure and the Icelandic low pressure and controls the intensity of the prevailing wind.
ResearchLed by a team of climate scientists in the Metropolitan Office, climate water vapor is identified as an important factor in the differences in long-term fluctuations in NAOs in climate model simulations. Research shows that the way current climate models represent water vapor in the atmosphere lead to uncertainty in predicting future behavior of NAOs. Given these limitations, NAO responds greatly to volcanic eruptions and greenhouse gases.
The results show that at the end of the century, with high concentrations of greenhouse gases, NAO will increase to unprecedented levels, thus constituting a serious impact of extreme weather such as floods and storm damage. However, these effects can be mitigated through efforts to reduce greenhouse gas emissions.
Chief Writer Dr. Doug Smithunderscoring the urgency of the findings: “These findings have a significant impact on understanding and preparing for extreme weather events. Our research shows that model predictions at face value may prevent society from preparing for the upcoming extremes. Mitigation efforts are crucial to prevent unprecedented severe impacts from NAO.”
The main findings of the study include:
- Studies have shown that some differences between NAO model projections are due to climate water vapor limitations in the model.
- The study reveals a significant response of NAO to external forcing such as volcanic eruptions and greenhouse gases.
- The study also considers the “signal-to-noise paradox”, which suggests that climate models may underestimate the magnitude of NAO changes in the real world.
- The findings highlight the importance of mitigation measures to avoid an unprecedented increase in NAO.
- The study highlights the need for improved climate models to better predict future changes in regional climates.

Without our mandatory need for us to abandon fossil fuels, the intimidation story of no Metropolitan Office is complete:
“But efforts to reduce greenhouse gas emissions can mitigate these effects.”
You may also notice that stupid panic is based on Very high greenhouse gases. In other words, RCP 8.5 is generally considered impossible.
But back in the real world, NAO has not become more extreme despite “global warming.”

NAO has the greatest impact on winter weather, but we once again find the extremes claimed by the Metropolitan Office, which is certainly going to become apparent after 200 years of warming.

The latest nonsense is another example of how the Metropolitan Office lost its reputation on scientific excellence, abandoned on its political agenda.
Now is the time for them to face the same cuts Trump has wisely imposed on NOAA.
