It’s too hot! What is happening?
With many around the world feeling the effects of the heatwaves this summer, eyes are turned towards government initiatives that aim to understand and combat climate change.
When it comes to the heatwaves in the northern hemisphere, they are undoubtedly connected to global warming, according to scientists. For instance, Prof Myles Allen, a climate scientist at the University of Oxford stated that there’s no question human influence on climate is playing a significant role in this heatwave.
In addition to many events affecting humans, the rate and manner of the change also put entire ecosystems at risk, which results in fewer natural resources being available to humans. These include capturing the carbon dioxide desk, naturally purifying the water and air, providing resources such as wood and sources of food, and much more.
Fortunately, observations made from space offer unique information which significantly helps to build a strong understanding and management of climate change. It is increasingly evident that these observations are essential, but as of now, there is not a coordinated, sustained programme which will ensure they are available to all.
As a response to this need ESA has launched a new programme called, Global Monitoring of Essential Climate Variables (known for short as the ESA Climate Change Initiative) as a way to offer an adequate, comprehensive, and timely response to the incredibly challenging set of requirements for (highly stable) long-term satellite-based products for climate, that have been addressed to Space Agencies through the Global Climate Observing System (GCOS) and the Committee on Earth Observation Satellites (CEOS). It is exclusively focused on addressing the explicit needs of UNFCCC.
NASA also has their own programs underway. For example, their Atmospheric Tomography Mission, known as ATom, will examine the impact of human-produced air pollution on greenhouse gases and chemically reactive gases in the atmosphere. Reductions of atmospheric concentrations of methane (CH4), tropospheric ozone (O3) and black carbon (BC) aerosols are effective ways to slow global warming and to improve air quality.
However, government agencies aren’t the only ones working to combat the issue of climate change. Professor Ernest Chua of the National University of Singapore is studying how to keep us cool without doing so much damage to Earth. Traditional air conditioning technology is over 100 years old, he noted, but we still have not made breakthroughs in evolving air conditioning that is more environmentally friendly.
Thus, Chua’s solution is an air-cooling device that runs exclusively on water. Hot air is sucked into a machine in which a special membrane eliminates moisture. Then the dried air is blown over a layer of water, cooling it down much like a breeze cools our sweaty skin.
