In a scientific breakthrough, researchers have engineered a new strain of bacteria that consumes carbon dioxide for energy instead of compounds like sugar or other organic molecules. Published in the journal Cell, the study effectively reprogrammed the E. coli bacterium's diet over generations. The scientists said that 'teaching a gut bacterium to do tricks that plants are renowned for was a real long shot,' but this may prove to be very healthy for the planet.

The deepest point of land on Earth has just been discovered beneath Antarctic ice, under the Denman Glacier by researchers at the University of California. The trench stretches 11,500 ft below sea level and was discovered as a part of creating the most detailed map of the land beneath Antarctica. Called BedMachine, the map shows the ridges and slopes that make up the landscape. This land, discovered is the deepest continental point on Earth, according to the team. During the research, the team also helped understand which regions of the continent will be more susceptible to the effects of climate change.

The United Nations climate conference in Madrid, COP25,&nbsp; on Thursday saw Santa Claus with a social message. Philip McMaster, who calls himself 'SustainaClaus' is an advocate of sustainable life. At the conference, he urged parents to become more conscious in the holiday season and echoed teen climate activist Greta Thunberg's message. He emphasised that world governments and individuals aren't doing enough to tackle the climate crisis. SustainaClaus suggested parents make their own gifts by hand and get rid of packaging to conserve the environment.

The irreversible impacts of climate change are coming much closer as Greenland's ice sheet is melting faster than expected.&nbsp; Researchers from the&nbsp;University of Leeds have found that ice is being lost from Greenland seven times faster than it was in the 1990s. This puts people living in&nbsp;low-lying coastal regions at an increasing risk. The new assessment&nbsp;comes from&nbsp;96 polar scientists who reviewed satellite observations over a period of 26 years. Experts concluded that an additional 7cm of ocean rise could be expected at the end of the century by Greenland alone.&nbsp;

She has inspired a global movement to fight climate change. By missing school every Friday last year to protest outside Swedish parliament, she taught the world the power of one. She has been criticising the politicians and corporate honchos for their lack of action on climate. At just 16 she has sparked a worldwide movement earning cheer from world, and also jeer from some of the leaders. She is Greta Thunberg and she has been named the Time Magazine's Person of the Year. Thunberg is the youngest person to be chosen by the magazine.

The world's first human composting facility will start its operations in Seattle by 2021. At Recompose, the aim is to convert human remains into soil. Earlier this year, Washington passed a bill that allows human composting and the law will go into effect in May 2020. The facility uses recomposition vessels that allow bacteria to act and the process takes around 30 days. The family of the deceased can take the soil to use in their gardens. Conservation of the environment is one massive benefit of the process, says the company.

Dubai&nbsp;International&nbsp;Airport and&nbsp;Al Maktoum International Airport&nbsp;will soon be free of single-use plastics in a bid to tackle their&nbsp;environmental impact.&nbsp;With 90 million passengers passing through Dubai's airport&nbsp;every year, tens of thousands of plastic items are consumed.&nbsp;Plastic cutlery, drinking straws, take-away food packaging and polythene bags will be removed from caf&eacute;s, restaurants and shops at one of the world's busiest airports from January 1, 2020.

Almost two billion people, a quarter of the world's population, are at risk of water shortage. Global heating and an increasing demand is making glaciers and lakes more vulnerable.&nbsp;32 scientists from around the globe authored the new study&nbsp;published&nbsp;in the&nbsp;Nature journal. A large group of people rely on&nbsp;mountain glacier-based systems for their regular supply of water. The study shows that densely populated basins like the Indus basin in South Asia could be highly vulnerable in the future due to climate change.&nbsp;

The oceans are losing oxygen at an unprecedented rate and this poses a major risk to tuna, sharks and other species. The findings were presented by the International Union for the Conservation of Nature at the&nbsp;UN climate conference in Madrid. They shared that "the delicate balance of marine life is thrown into disarray" as the ocean loses oxygen. While all fish need oxygen to survive, the bigger species are more vulnerable to these depleting levels as they need more oxygen to survive. They are thus moving towards the shallow areas of sea, where they are vulnerable to fishing. Global heating is a major source of this depleting oxygen levels.&nbsp;

Honouring marine species that have lost their lives to plastic pollution, few environmental groups have come together to build the world's first marine cemetery. Located at the&nbsp;Beypore Beach in&nbsp;Kozhikode&nbsp;in&nbsp;Kerala, the cemetery has been made of over 2000 plastic bottles, featuring 9 tombs. 8 critically endangered marine species including seahorse, hammerhead shark, parrotfish&nbsp;and&nbsp;leatherback turtle have been honoured at the cemetery. The project was led by Jellyfish Watersports.

The Bhadrinarayan Temple in Surat has switched to solar power to meet its energy needs. High electricity bills led the management to make the switch, after which they were able to save the money that is now being used to provide education to children in the region. The trustee of the temple stated that fifty kilowatt capacity solar panels have been installed on the terrace of the temple.

Teenage climate activist Greta Thunberg&nbsp;has once again hit out at world leaders, accusing them of 'silencing' the youth. Addressing a climate rally in Madrid, Thunberg said, "people want everything to continue like now and they are afraid of change". Thunberg also added that calls for real action against climate change are still being "ignored" by political leaders. Thunberg&nbsp;is in Madrid while&nbsp;the United Nations-sponsored talks on climate change is underway. The march was led by dozens of representatives of Latin America's indigenous peoples and organisers claimed 500,000 people showed up for the march.

A village in Russia's Far East is on high alert due to a polar bear invasion. Hungry polar bears and their cubs descended on a village in search of food. According to World Wide Fund, some 50 bears are roaming near Ryrkaipiy village, since they were unable to hunt at sea and moved to populated areas to search for something to eat. Social activities have been cancelled and patrols have been appointed to protect locals.

Norwegian Air has become the first airline to sign the UN Climate Pledge,&nbsp;committing to become climate neutral by 2050. Passengers will be able to see their flight&rsquo;s carbon emissions and purchase offsets with their ticket. Customers who choose to purchase offsets will fund carefully selected CO2-reducing clean energy projects in regions Norwegian serves.&nbsp;Over the past 10 years, the airline has &ldquo;reduced its emissions by 30 percent per passenger kilometer&rdquo; by operating fuel-efficient aircraft.&nbsp;

Climate change is causing birds to shrink, says a new study conducted by researchers from the&nbsp;University of Michigan and the&nbsp;Field Museum in Chicago.&nbsp;Researchers analysed over 70,000 specimens from 52 North American migratory bird species collected over 40 years. They found that almost all of the species were getting smaller and&nbsp;their wingspans are growing.&nbsp;However, scientists aren't exactly sure why warmer temperatures cause birds to shrink.&nbsp;More studies may help understand&nbsp;how animals will adapt to climate change.

According to the Centre for International Climate Research, carbon emissions have increased by about 0.6% over the course of 2019. The 2019 estimate is based on data through the first nine to ten months of the year, with a few national estimates based only on six months of data.&nbsp;Both the United States and the European Union saw emissions drop 1.7% from 2018 to 2019, but China saw a 2.6% increase and India had a 1.8% rise. China is by far the biggest carbon polluter, with 28% of the 2019 emissions. The United States is No. 2 at 14.5%.

Ahead of the COP25 climate change meeting, an art installation has been created in Madrid that recreates air pollution. The installation simulates pollution levels of some of the most polluted cities in the world including London, New Delhi and Beijing. The pollution pods have been created by British artist Michael Pinsky and use perfume blends and fog machines to imitate the deteriorating&nbsp;air quality. Spain's Energy and Environment Minister Teresa Ribera paid a visit to the site that even spreads awareness on how pollution impacts the health.

The Six Flags Discovery Kingdom in Vallejo in California has become the first theme park on the West Coast powered by solar energy. Recently, an event&nbsp;was organized to celebrate the park's commitment to renewable energy including the flipping of a giant switch and illuminating millions of twinkling lights.

A team of scientists used a drone to capture the rapid fracturing and draining of a lake on the Greenland ice sheet, a phenomenon that could become more frequent as a result of climate change. The process is difficult to capture, but the group of glaciologists from the Scott Polar Institute at the University of Cambridge were fortunate when they arrived at the Store Glacier in northwest Greenland in July 2018.&nbsp;Aerial photography captured by the drone from before and after shows a dark blue oval shrinking into a smaller, shallower and lighter blue circle.

Marine Conservation Society in the UK found almost 16,000 cans and bottles in four days of beach cleaning in September. The revelation&nbsp;highlights the importance of a&nbsp; comprehensive&nbsp;deposit return scheme to avoid marine litter. As part of the Great British Beach Clean, more than 10,000 volunteers cleaned&nbsp;437 beaches and collected almost 11 tonnes of litter.&nbsp;

The dangers of marine litter once again come to light with the viral photograph of a seal pup with a glass bottle in its mouth. Photographer Dan Thurling&nbsp;took the photo at&nbsp;Donna Nook reserve in Lincolnshire. The glass bottle is apparently from Starbucks and the chain has offered its support to protect the area.&nbsp;
