We think of clouds as insubstantial. But they matter far beyond their weight or tangibility. In dry Western Australia where I live, rain-bringing clouds are eagerly anticipated. But the winter storms which bring most rain to the south-west are being pushed south<\/a>, depositing vital fresh water into the oceans<\/a>. More and more days pass under a hard, endless blue \u2013 beautiful, but also brutal in its vacancy. <\/p>\n Worldwide, cloud patterns are now changing in concerning ways. Scientists have found the expanse of Earth\u2019s highly reflective clouds is steadily shrinking<\/a>. With less heat reflected, the Earth is now trapping<\/a> more heat than expected<\/a>. <\/p>\n A quiet crisis above<\/p>\n When there are fewer and fewer clouds, it doesn\u2019t make headlines as floods or fires do. Their absence is quiet, cumulative and very worrying. <\/p>\n To be clear, clouds aren\u2019t going to disappear. They may increase in some areas. But the belts of shiny white clouds we need most are declining<\/a> between 1.5 and 3% per decade. <\/p>\n These clouds are the best at reflecting sunlight back to space, especially in the sunniest parts of the world close to the equator. By contrast, broken grey clouds reflect less heat, while less light hits polar regions, giving polar clouds less to reflect.<\/p>\n Clouds are often thought of as an ambient backdrop to climate action. But we\u2019re now learning this is a fundamental oversight. Clouds aren\u2019t d\u00e9cor \u2013 they\u2019re dynamic, distributed and deeply consequential infrastructure able to cool the planet and shape the rainfall patterns seeding life below. These masses of tiny water droplets or ice crystals represent climate protection accessible to all, regardless of nation, wealth or politics. <\/p>\n On average, clouds cover two-thirds<\/a> of the Earth\u2019s surface, clustering over the oceans. Of all solar radiation reflected back to space, clouds are responsible for about 70%. <\/p>\n Clouds mediate extremes, soften sunlight, ferry moisture and form invisible feedback loops<\/a> sustaining a stable climate. <\/p>\n Earth\u2019s expanse of white, reflective clouds is shrinking decade after decade. When loss is invisible<\/p>\n If clouds become rarer or leave, it\u2019s not just a loss to the climate system. It\u2019s a loss to how we perceive the world. <\/p>\n When glaciers melt, species die out or coral reefs bleach and die, traces are often left of what was there. But if cloud cover diminishes, it leaves only an emptiness that\u2019s hard to name and harder still to grieve. We have had to learn how to grieve other environmental losses. But we do not yet have a way to mourn the way skies used to be.<\/p>\n And yet we must. To confront loss on this scale, we must allow ourselves to mourn \u2013 not out of despair, but out of clarity. Grieving the atmosphere as it used to be is not weakness. It is planetary attention, a necessary pause that opens space for care and creative reimagination of how we live with \u2013 and within \u2013 the sky.<\/p>\n Seen from space, Earth is a planet swathed in cloud. Reading the clouds<\/p>\n For generations, Australia\u2019s First Nations have read the clouds and sky<\/a>, interpreting their forms to guide seasonal activities. The Emu in the Sky<\/a> (Gugurmin in Wiradjuri) can be seen in the Milky Way\u2019s dark dust. When the emu figure is high in the night sky, it\u2019s the right time to gather emu eggs. <\/p>\n The skies are changing faster than our systems of understanding can keep up<\/a>. <\/p>\n One solution is to reframe how we perceive weather phenomena such as clouds. As researchers in Japan have observed<\/a>, weather is a type of public good \u2013 a \u201cweather commons\u201d. If we see clouds not as leftovers from an unchanging past, but as invitations to imagine new futures for our planet, we might begin to learn how to live more wisely and attentively with the sky.<\/p>\n This might mean teaching people how to read the clouds<\/a> again \u2013 to notice their presence, their changes, their disappearances. We can learn to distinguish<\/a> between clouds which cool and those which drift, decorative but functionally inert. Our natural affinity to clouds makes them ideal for engaging citizens<\/a>. <\/p>\n To read clouds is to understand where they formed, what they carry and whether they might return tomorrow. From the ground, we can see whether clouds have begun a slow retreat from the places that need them most. <\/p>\n Learning to read the clouds can help us glimpse the changes above. Weather doesn\u2019t just happen<\/p>\n![\"single](\"https:\/\/www.europesays.com\/ie\/wp-content\/uploads\/2025\/12\/file-20251208-56-hkbxyf.jpg\")
