  • Hottest March on Record: Earth’s Alarming Temperature Trend

    Hottest March on Record: Earth’s Alarming Temperature Trend

    March was the hottest month ever recorded, says the European Union’s Copernicus Climate Change Service (C3S). This is part of a worrying pattern where each of the last ten months has broken records for warmth compared to previous years.

    Hottest March on Record

    The world is heating up fast, and it’s causing big problems for our planet. The past year, ending in March, was the hottest 12 months ever recorded. This shows that global warming is happening faster than ever before.

    Samantha Burgess, from Copernicus Climate Change Service, says that March’s record-breaking temperature isn’t the only problem. Other months in the past year have also been much hotter than usual. This is a sign that our climate is changing quickly, and not for the better.

    The Earth’s temperature rising so fast is causing many problems around the world. There have been more wildfires in the Amazon rainforest because of droughts caused by climate change. In Southern Africa, crops are dying because of the heat, and millions of people are going hungry.

    Another big problem caused by rising temperatures is the bleaching of coral reefs in the Southern Hemisphere. This is happening because the oceans are getting warmer, and it’s a huge threat to marine life.

    The main reason the Earth is getting hotter is because of human activities, like burning fossil fuels. This releases greenhouse gases into the atmosphere, trapping heat and making the planet warmer. Even when natural events like El NiƱo, which warms the Pacific Ocean, happen, it’s not enough to stop the warming caused by humans.

  • Polar Vortex: Scientists Warn of Rapid Polar Temperature Changes

    Polar Vortex: Scientists Warn of Rapid Polar Temperature Changes

    Polar Vortex

    In 2019, extreme cold in the US Midwest claimed 21 lives. It was so cold that boiling water instantly froze when exposed to the outside air. America has faced similar cold periods in the past, like in 1977, 1982, 1985, 1989, and 2014.

    Scientists are using advanced technology like computer algorithms, satellites, and weather balloons to study the vortex in detail. During a cyclone, the weather can suddenly turn very cold, causing drastic changes in the atmosphere.

    These catastrophic events are linked to climate change and global warming. As the temperature gap between central and polar regions shrinks, polar air flows more towards the south. This can lead to extreme cold, snowstorms, and winter storms in unexpected places, posing risks to human life and disrupting transportation systems.

    Scientists worry that such events may not only affect America but also Europe and Canada. To prevent this, reducing arctic temperatures, increasing the use of renewable energy, and cutting greenhouse gas emissions are crucial steps. This will help lessen the occurrence of these dangerous weather patterns.

  • District Cooling: Singapore’s Green Approach to Temperature Control

    District Cooling: Singapore’s Green Approach to Temperature Control

    When one region’s temperature significantly rises above its surroundings, it stands out like an isolated island on a thermal map. In today’s world, urban areas are experiencing higher temperatures due to growing populations and climate change. As a result, people are suffering more during the summer.

    Singapore

    Singapore city, in particular, is witnessing a gradual increase in temperature. Being located near the equator, the city’s temperature can reach as high as 32 degrees Celsius during the day. Singapore is heavily urbanized, with numerous tall buildings, which contributes to this temperature rise.

    Nevertheless, the Singaporean government is taking stringent measures to control the heat. Extensive research is underway to combat rising temperatures. One notable effort is the creation of a 225-acre park on the bay’s shores known as ‘Gardens by the Bay.’ Within this park lies the Flower Dome, a greenhouse where you can experience a comfortable temperature of 24 degrees Celsius. Additionally, there are 24 cooling towers nearby.

    What makes this system unique is the large underground air-conditioning system that helps maintain a cool environment. This system circulates cooling water through pipes to various buildings in the central network. When needed, machines further cool the water before delivering it to places like shopping malls, residential buildings, hospitals, and private offices. This innovative approach is called the ‘District Cooling System’ and saves forty percent more electricity compared to traditional air conditioning.

    The Singaporean government has set an ambitious goal of planting 1 million trees by 2031 as part of its initiative to reduce the city’s heat. This move is crucial for mitigating the rising temperatures in urban areas. Singapore has a history of success with such strategies, and its efforts to create more comfortable and livable cities are commendable.

    The increasing temperatures in urban areas, like Singapore city, pose challenges to the well-being of residents. However, the Singaporean government’s proactive approach, such as the development of ‘Gardens by the Bay’ and the innovative ‘District Cooling System,’ shows their commitment to combatting this issue. By setting goals like planting 1 million trees, Singapore is taking significant steps to create a more comfortable and sustainable urban environment.

  • Insights into Early Universe: Mapping Temperature Changes in Ancient Galaxies

    Insights into Early Universe: Mapping Temperature Changes in Ancient Galaxies

    Astronomers used a powerful telescope called ALMA to create a temperature map of an old galaxy’s dust. This map showed differences in temperature between the central supermassive black hole and the cooler areas where stars form. The study helps us understand how galaxies and their black holes grow in the early Universe.

    Spiral-Galaxy

    The researchers found that the temperature of the dust in the galaxy can vary depending on where it is located. They were able to measure the temperature in different regions, which was challenging before because of limited instrument resolution. This new map provided clear evidence of temperature variations, suggesting two sources of heat: the black hole at the center of the galaxy and the heat from newly-formed stars in the surrounding rotating disk.

    Dr. Takafumi Tsukui from the Australian National University led the study. He explained that most distant galaxies’ dust temperatures were measured as a whole, but they wanted to measure temperature region by region to understand individual heat sources. Previous temperature mapping was mostly limited to nearby galaxies.

    The research revealed that the central region of the galaxy had warm dust, heated by the supermassive black hole. In contrast, the outer region had colder dust, likely heated by star formation. It’s common for galaxies to have a supermassive black hole in the center, and as the galaxy grows, the black hole also increases in mass. When gas accretes to the black hole, collisions with fast-moving particles heat it up, sometimes making it shine brighter than the rest of the galaxy.

    The heating energy from the black hole reveals how much gas is being fed into it and thus its growth rate. On the other hand, the heating energy from star formation indicates how many new stars are forming in the galaxy, reflecting the galaxy’s growth rate.

    This discovery gives us a clearer understanding of how galaxies and their central black holes form and grow in the early Universe.

    The researchers were able to conduct this study thanks to the ALMA telescope operated by the European Southern Observatory in Chile. ALMA is a powerful telescope for measuring millimeter and submillimeter radiation. It allowed them to look at a 12-billion-year-old galaxy and separate the image into two components: one with dust heated from the central supermassive hole and the other with dust from the underlying host galaxy.

    The detailed temperature map provided by ALMA helps scientists gain insights into the galaxy’s evolution. Prior to this study, they could only measure the temperature of distant galaxies in broad terms. Now, with this advanced technology, they can understand temperature variations in individual areas, which gives a better understanding of how galaxies evolve over time.
