Paula Dupraz-Dobias at New Humanitarian: “Localised data can help governments project climate forecasts, prepare for disasters as early as possible, and create long-term policies for adapting to climate change.

Wealthier countries tend to have better access to new technology that allows for more accurate predictions, such as networks of temperature, wind, and atmospheric pressure sensors.

But roughly half the world’s countries do not have multi-hazard early warning systems, according to the UN’s World Meteorological Organization. Some 60 percent lack basic water information services designed to gather and analyse data on surface, ground, and atmospheric water, which could help reduce flooding and better manage water. Some 43 percent do not communicate or interact adequately with other countries to share potentially life-saving information.

The black holes in weather data around the globe

WMO/ECMWFUS reports weather observations every three hours, as opposed to the every hour required by World Meteorological Organization regulations. It says it will comply with these from 2023.

“Right now, we can analyse weather; in other words, what happens today, tomorrow, and the day after,” said Ena Jaimes Espinoza, a weather expert at CENEPRED, Peru’s national centre for disaster monitoring, prevention, and risk reduction. “For climate data, where you need years of data, there is still a dearth [of information].”

Without this information, she said, it’s difficult to establish accurate trends in different areas of the country – trends that could help forecasters better predict conditions in Tarucani, for example, or help policymakers to plan responses.

Inadequate funding, poor data-sharing between countries, and conflict, at least in some parts of the world, contribute to the data shortfalls. Climate experts warn that some of the world’s most disaster-vulnerable countries risk being left behind as this information gap widens…(More)”.

Article by Chris Mooney, Juliet Eilperin, Desmond Butler, John Muyskens, Anu Narayanswamy, and Naema Ahmed: “Across the world, many countries underreporttheir greenhouse gas emissions in their reports to the United Nations, a Washington Post investigation has found. An examination of 196 country reports reveals a giant gap between what nations declare their emissions to be versus the greenhouse gases they are sending into the atmosphere. The gap ranges from at least 8.5 billion to as high as 13.3 billion tons a year of underreported emissions — big enough to move the needle on how much the Earth will warm.

The plan to save the world from the worst of climate change is built on data. But the data the world is relying on is inaccurate.

“If we don’t know the state of emissions today, we don’t know whether we’re cutting emissions meaningfully and substantially,” said Rob Jackson, a professor at Stanford University and chair of the Global Carbon Project, a collaboration of hundreds of researchers. “The atmosphere ultimately is the truth. The atmosphere is what we care about. The concentration of methane and other greenhouse gases in the atmosphere is what’s affecting climate.”

At the low end, the gap is larger than the yearly emissions of the United States. At the high end, it approaches the emissions of China and comprises 23 percent of humanity’s total contribution to the planet’s warming, The Post found…

A new generation of sophisticated satellites that can measure greenhouse gases are now orbiting Earth, and they can detect massive methane leaks. Data from the International Energy Agency (IEA) lists Russia as the world’s top oil and gas methane emitter, but that’s not what Russia reports to the United Nations. Its official numbers fall millions of tons shy of what independent scientific analyses show, a Post investigation found. Many oil and gas producers in the Persian Gulf region, such as the United Arab Emirates and Qatar, also report very small levels of oil and gas methane emission that don’t line up with other scientific data sets.

“It’s hard to imagine how policymakers are going to pursue ambitious climate actions if they’re not getting the right data from national governments on how big the problem is,” said Glenn Hurowitz, chief executive of Mighty Earth, an environmental advocacy group….(More)”.
