Weather of Arabia - Despite the geographical distributions and political divisions, we share one land. Our weather, climate, and water cycle on Earth know no international or political borders. This philosophy has prompted the meteorological community in the world to provide global services and unify data that support weather and climate predictions for current and future generations. This will be the slogan of the year on World Meteorological Day.
This year marks the 150th anniversary of the founding of the World Meteorological Organization, and on World Meteorological Day (23-3-2023) the organization highlights the past achievements, current progress and future potential of the meteorological community, beginning with the use of the telegraph in the late nineteenth century, Down to supercomputers and supporting space technology, this advance tells a fascinating story of scientific vision, technological development, and collaboration to serve society.
The anniversary is also a reminder of our changing climate, since the founding of the International Meteorological Organization in 1873 when pollution from industrial and human activities was in its infancy.
Now, as a result of greenhouse gases that trap heat, the average global temperature is more than 1°C higher than it was 150 years ago . Earth's weather is more extreme, oceans are warmer and more acidic, and sea levels are rising as a result of melting glaciers and sea ice. And because the rate of change is accelerating, the world needs to take urgent action to reduce emissions to protect current and future generations.
According to the World Meteorological Organization, rapid scientific and technological progress (including machine learning and artificial intelligence) has improved the accuracy of weather forecasts and early warnings to a large extent, as big data is shared more freely between societies, which will support the decision-making process.
According to what the world is witnessing, it is expected that the demand for forecast information related to weather, climate and water will increase rapidly in the coming years in support of decision-making. After, smart mobile devices, continuous scientific progress, international cooperation and participation between the public and private sectors.
The Intergovernmental Panel on Climate Change expects climate changes to increase in the coming decades in all regions, including:
Climate change intensifies the water cycle, bringing more heavy rains and floods to some areas, and severe droughts to others.
Hence the need for urgent and integrated water and climate action and improved water monitoring and management to ensure that water is part of the climate solution and not just a problem.
And if you don't take immediate action to reduce greenhouse gas emissions, limiting global warming to 1.5°C is out of reach, according to the latest report of the Intergovernmental Panel on Climate Change.
The global temperature will stabilize when carbon dioxide emissions reach net zero, for 1.5°C this would mean achieving net global carbon dioxide emissions in the early 2050s.
Among the measures that contribute to reducing emissions, a continuous decrease since 2010 of up to 85% in the costs of solar and wind energy, and a growing set of policies and laws have led to enhancing energy efficiency, reducing deforestation rates, and accelerating the deployment of renewable energy, as the WMO community is working ) to improve weather and climate services in the field of renewable energy.
There are hopes for zero emissions as long as all generations unite to confront the climate change crisis, and with a conscious generation of young people at the forefront of climate action, we always remember that our work today will shape the future of the planet.
