    What is Net Zero

    What is Net Zero

    Five years ago, the United Nations Paris climate agreement set a ceiling for global warming at well below 2 °C, ideally 1.5 °C relative to pre-industrial levels.

    To achieve this everyone from the United States, China, the European Union, to the technology firm Microsoft and even an alliance of European airports are saying they will achieve “net-zero” greenhouse gas emissions this century.

    But what is Net Zero? And is it the solution to global warming?

    When will the world exceed 1.5C and 2C of global warming?

    When will the world exceed 1.5C and 2C of global warming?

    While the growth of global emissions has slowed in recent years, there is a large and growing gap between current commitments and what would be needed to avoid exceeding these global temperature limits.

    Carbon Brief has provided an analysis of when the world is expected to pass these limits in the absence of large future emissions reductions.

    Their analysis shows that:

    The world will likely exceed 1.5C between 2030 and 2032 in scenarios where emissions are not rapidly reduced

    The 2C threshold will likely be exceeded between 2043  in the highest emissions scenario

    In a scenario of modest mitigation – where emissions remain close to current levels – the 2C threshold would be exceeded around 2052.

    Is Climate Change getting better?

    Is Climate Change getting better?

    On today’s podcast we will answer the question  is climate change getting better?

    While this year will be memorable for many reasons, it is now more likely than not that 2020 will also be the warmest year for the Earth since reliable records began in the mid-1800s.

    The first nine months of the year saw record concentrations of major greenhouse gases – CO2, methane, and nitrous oxide – in the atmosphere - driven by human emissions from fossil fuels, land use and agriculture.

    How bad is flying for the environment?

    How bad is flying for the environment?

    Around 2.4% of global CO2 emissions come from aviation. Together with other gases and the water vapour trails produced by aircraft, the industry is responsible for around 5% of global warming.

    On today’s podcast we will answer the question ‘’How bad is flying for the environment?’

    Why is meat bad for the environment?

    Why is meat bad for the environment?

    In 2019 a high-level report commissioned by the United Nations concluded that a huge reduction in meat-eating is ‘essential’ to avoid climate breakdown and keep global heating under 2C.

    According to the report the average world citizen needs to eat 75% less beef, 90% less pork and half the number of eggs, while tripling consumption of beans and pulses and quadrupling nuts and seeds.

    So why is meat so bad for the environment?
