The accord is the first major step towards limiting global warming after the Paris Agreement was reached in December 2015. (...) HFCs, however, do not impact the ozone, but have high global warming potential. The extension of the treaty’s scope opens a new era for the Montreal Protocol to phase down substances with high global warming potential. (...) In developing countries, demand for refrigeration and air conditioning is growing rapidly. Currently, demand encompasses more than 40 per cent of total electricity consumption, and this is expected to rise due to economic and demographic growth, urbanization and global warming.

These sooty particles absorb sunlight and warm the Earth. Another short-lived cause of warming is ozone in the lower atmosphere. (...) These measures, all using existing, proven technology, will reduce projected global warming by nearly half over the next three decades, while leading to between 1 and 4 million fewer premature deaths per year from outdoor air pollution, and to increased crop yields by 30 to 135 million tonnes per year. (...) Such efforts are in each nation's own interest, as they would produce large air quality benefits, as well as serve the global community via reduced global warming.

The Montreal Protocol is considered the most successful international environmental agreement ever . Fighting global warming But the Montreal Protocol is not just saving the ozone layer. (...) Such mono-split air conditioners enjoy annual global sales of more than 100 million units, about 70 per cent of which are made in China. (...) In the past, as chlorofluorocarbons and hydrochlorofluorocarbons have been phased out under the Montreal Protocol, the use of HFCs has greatly increased, particularly in the refrigeration and air conditioning sector s . HFCs do not impact the ozone, but have high global warming potential.

Human activities have warmed the atmosphere, ocean and land, producing widespread and rapid changes in the atmosphere, ocean, cryosphere and biosphere. 2. (...) The more the world warms, the greater the changes in the climate system become. (...) Limiting human-induced global warming requires limiting cumulative carbon dioxide emissions, reaching at least net zero.

In the long term, warming induced by aviation CO2 is largest. At short terms, warming by aviation NOx and contrails is larger than that by aviation CO2.

Time is running out The IPCC scientists warn global warming of 2°C will be exceeded during the 21st century. (...) The report makes clear that while natural drivers will modulate human-caused changes, especially at regional levels and in the near term, they will have little effect on long-term global warming. Air pollution from power plants contributes to global warming. Unsplash/Maxim Tolchinskiy A century of change, everywhere The IPCC experts project that in the coming decades climate changes will increase in all regions. For 1.5°C of global warming, there will be increasing heat waves, longer warm seasons and shorter cold seasons.

I learned how to recognize the signs of jaundice, how to bathe her, how to refresh the air in her room, how to keep her warm, and how to feed her. (...) I also learned that, every two hours, the window should be opened for five minutes to clean the air of the home. Before the training, I thought that closed windows kept a baby warm. But they only gave her frequent colds. When the air is clean, a baby has no stuffy nose. I also learned how to correctly wrap the baby and keep her head [the fontanelle] warm – that’s why I always put on a hat.

“It normally keeps cold air in the Arctic, warmer air in the lower latitudes. It weakened this winter so that meant that the cold air came spinning out of the Artic…warm air by contrast went into parts of the Arctic.” (...) The UN agency also cautioned that although February was a relatively cold month, this does not negate the long-term warming trend from climate change. “Cold records are becoming rarer, in contrast to heat temperature records and heatwaves.
