Researchers from TU Delft and 18 other partners receive the Horizon Europe grant for their project called ...

Offering a foretaste of what’s to come once it is fully commissioned, ESA’s EarthCARE satellite has returned the first images from its broadband radiometer instrument. These initial images offer a tantalising glimpse into the intricacies of our planet’s energy balance – a delicate balance that governs our climate. Earth’s energy balance accounts the amount of ...

As the planet continues to warm due to human-driven climate change, accurate computer climate models will be key in helping illuminate exactly how the climate will continue to be altered in the years ahead. In a study published in the Journal of Geophysical Research: Atmospheres, a team led by researchers from the UC Irvine Department ...

The Earth’s spin axis is not constant. It moves slowly over time relative to the Earth’s crust. This is caused by various processes on the surface and inside the Earth, such as the melting of ice masses or the uplift of land masses, as well as mass shifts in the Earth’s viscous mantle and core. ...

The impacts of climate change are being felt all over the world, but how will it impact how your hometown feels?

In the late 2000s, Scott Saleska observed an unusual phenomenon in the Amazon rainforest. A severe drought in 2005 led to increased green growth in vast areas of the Amazon, contrary to field researchers’ observations of browning plants and some dying due to the drought. Recent research published in Nature by Shuli Chen, a doctoral ...

A research initiative, funded by NASA and the Army Corps of Engineers, is underway to study permafrost thaw in Alaska and its significant impacts on the environment. This project aims to understand the landforms created by thawing permafrost, how it affects methane emissions and whether the rate of permafrost thaw is accelerating. Leading this research ...

Scientists have built a highly accurate digital simulation of planet Earth to provide reliable information about extreme weather and climate change. This AI-powered “digital twin” virtually simulates the interaction between natural phenomena and human activities to predict their effect on things like water, food and energy systems. In the past, climate and weather predictions have ...

The TRISHNA (Thermal Infra-Red Imaging Satellite for High-resolution Natural Resource Assessment) mission, a collaborative endeavor between ISRO and CNES, is engineered to deliver high spatial and high temporal resolution monitoring of Earth’s surface temperature, emissivity, biophysical and radiation variables for surface energy budgeting at regional to global scale. This mission addresses critical water and food ...

The movement of carbon between the atmosphere, oceans and continents — the carbon cycle — is a fundamental process that regulates Earth’s climate. Some factors, like volcanic eruptions or human activity, emit carbon dioxide into the atmosphere. Others, such as forests and oceans, absorb that CO2. In a well-regulated system, the right amount of CO2 ...

Information from the PREFIRE mission will illuminate how clouds and water vapor in the Arctic and Antarctic influence the amount of heat the poles radiate into space. A pair of new shoebox-size NASA satellites will help unravel an atmospheric mystery that’s bedeviled scientists for years: how the behavior of clouds and water vapor at Earth’s ...

ESA’s EarthCARE satellite, poised to revolutionise our understanding of how clouds and aerosols affect our climate, has been launched. This extraordinary satellite embarked on its journey into space on 29 May at 00:20 CEST (28 May, 15:20 local time) aboard a Falcon 9 rocket from the Vandenberg Space Force Base in California, US. Just 10 ...

Climate change stands as one of the most pressing challenges confronting global ecosystems and human livelihoods. The agriculture sector of Anuradhapura district, Sri Lanka, well renowned for its pivotal role in the nation’s food production, faces an increasing threat from the changing climate. A recent study by Millennium City aims to incorporate the indicator system ...

To accelerate efforts to combat the $140 billion in economic losses due to extreme weather brought on by climate change, NVIDIA today announced its Earth-2 climate digital twin cloud platform for simulating and visualizing weather and climate at unprecedented scale. Part of the NVIDIA CUDA-X™ microservices, announced separately today, Earth-2’s new cloud APIs on NVIDIA ...

Climate change intensifies disasters, which drives displacement. That can, among many impacts, push internally displaced people from rural areas into urban slums. That in turn raises the risks of forced evictions and secondary urban displacement, as well as increased risks of public health crises, and so on, in a dispiriting causal chain. Knowing, in detail, ...

The Climate Council’s Heat Map of Australia is an interactive tool that shows how cutting climate pollution will limit extreme heat in our neighbourhoods. It projects the average number of hot and very hot days, as well as very hot nights, for each suburb by 2050 and 2090, and across three scenarios: no action, continuing ...

Google and environmental group Environmental Defense Fund on Wednesday unveiled a partnership to expose sources of climate-warming emissions from oil and gas operations that will be detected from space by a new satellite. MethaneSAT will launch next month, one of several satellites that are being deployed to monitor methane emissions across the globe to pinpoint ...

Arrivano dai dati satellitari gli strumenti per mappare il fenomeno dell’isola di calore urbana e capire come la struttura fisica della città e l’uso del suolo influiscano sul microclima urbano. Se ne parla al convegno che si terrà venerdì 23 febbraio presso il complesso monumentale dell’Acquario Romano, sede dell’Ordine degli Architetti di Roma e Provincia. ...

ESA and the Commission’s Directorate-General for Climate Action (CLIMA) are, therefore, seizing the opportunity to harness their combined expertise and resources to bring about transformative change, not least in the context of the EU’s Copernicus space programme and ESA’s Space for a Green Future Accelerator. ESA and CLIMA are reinforcing their cooperation by working together ...

If you’ve been wondering what climate change means for your neighborhood, you’re in luck. The most detailed interactive map yet of the United States’ vulnerability to dangers such as fire, flooding, and pollution was released in early October by the Environmental Defense Fund and Texas A&M University. The fine-grained analysis spans more than 70,000 census ...

As the impacts of climate change increase and intensify around the world, one aspect that has become clear is the geographic nature of the issue. The ability to tackle such a wide-reaching geographic challenge requires technology that gives context, which location intelligence provides. To support the individuals working toward this goal, Esri, the global leader ...

Methane is a powerful greenhouse gas and is the second-largest contributor to climate warming after carbon dioxide. A tonne of methane, despite its shorter lifespan of about 10 years in the atmosphere, can retain an astounding 30 times more heat than a tonne of carbon dioxide over the course of a century. This means that ...
