President Biden’s recognition of climate change, and determination to shift science to the centre of climate policy is important, and welcome. But a program that “achieves a carbon pollution-free power sector by 2035 and puts the US on an irreversible path to a net-zero economy by 2050” will not be enough. Adaptation to a 3.0°C temperature rise this century must now be a focus for governments.

Collective emission reduction efforts of nations will not avoid 3 degrees centigrade global warming by the end of the century. Therefore, national adaptation actions will need to prepare for the worse than expected scale and impact of climate change. Earlier ideological assumptions about governments will have to give way to policies that are interventionist and systemic.

In energy transition conversations, hydrogen is having a bit of a moment. But, as ever, there’s a catch. So here, from the Union of Concerned Scientists’ Julie McNamara, an introduction to hydrogen as a decarbonisation pathway, to help differentiate between the promise and potential and the distractions and misdirections.

Future pandemics will emerge more often, spread more rapidly, do more damage to the world economy and kill more people than COVID-19 unless there is a transformative change in the global approach to dealing with infectious diseases, warns a major new report on biodiversity and pandemics by 22 leading experts from around the world.

The fact that the International Monetary Fund recognises the urgency of addressing anthropogenic induced climate change and the importance of reducing carbon emissions from human activity by 2050 must be seen as a welcome step. But the report is impractical and naïve in some respects. The next step needs to go beyond the high level of abstraction that smooths over the diversity of economic, political and climate impacts in local situations.

Without assistance, emerging economies and developing countries (EEDCs) will continue to add increasing amounts of greenhouses gases to the atmosphere for decades, preventing the curbing of global warming and adversely impacting all countries. While EEDCs were always going to require substantial assistance from the advanced economies, the need for strong multilateral action has become more urgent.

Reuters reports that, according to an annoucement from China’s state news agency Xinhua on Saturday 17 October 2020, China’s top legislative body, the National People’s Congress Standing Committee, passed a new biosecurity law aimed at preventing and managing infectious diseases.

The International Monetary Fund has released its World Economic Outlook October 2020: A Long and Difficult Ascent, calling for global carbon emissions to decline to zero by mid-century, and setting out a model of what might be achieved.

A new UNDRR report shows that natural disasters caused by climate-related events have doubled in the past twenty years, affecting billions of people and costing trillions of dollars. The report highlights the need for governments to plan to spend more to deal with the impact and consequences of natural disasters.

The first multilateral attempt to legally bind countries to emissions cuts will enter into legal force on 31 December 2020, one day before the treaty expires. Does it matter, or is the outcome largely symbolic?

The urgent need to reduce carbon emissions can be usefully compared to filling a bathtub without a drain. Until the emissions tap is turned off completely, the bath keeps filling. And even when the tap is turned off, the bath is still filled to an undesirably high level. If the tap is never turned off, or turned off too late, in time the bath overflows disastrously. The Australian government’s extraordinary new fossil-fuel centred energy plan ensures the emissions tap will continue to flow.

The UNHCR’s Global Trends report brings together important information about the scale and changing nature of forced displacement. The Report describes a reality that solutions for refugees are in decline, at the same time that “we are witnessing a changed reality in that forced displacement nowadays is not only vastly more widespread but is simply no longer a short-term and temporary phenomenon”.

Governments around the world are planning to produce about 50% more fossil fuels by 2030 than would be consistent with the 2015 Paris Climate Agreement pathways. What can be done?

The Paris climate agreement seeks to limit global warming to 1.5℃ this century, a target likely to be exceeded by 2024. This first overshoot would be temporary – but it casts new doubt on whether Earth’s climate can be permanently stabilised at 1.5℃ warming. Modelling shows that if emission reductions are large and sustained, the Paris goals can still be met, and the most severe damage to the natural world, economy and people may be avoided. But worryingly, we also have time to make it far worse.

A new set of reports highlight the failure of governments to deal with the coming climate disaster. The unsurprising news is that current emissions of both CO2 and CH4 are not on track to limit global warming to the levels which were the goal of the Paris Agreement. None of this is a revelation to anyone following climate issues. However, what continues to amaze is the apparent repeated inability of this alarming information to have an impact on policy makers.

Concentrations of greenhouse gases in the Earth’s atmosphere are at record levels, and emissions that saw a temporary decline due to the pandemic are heading towards pre-COVID levels, while global temperatures continue to hit new highs, according to a major new UN report. UN Secretary-General António Guterres emphasized that there is “no time to delay” if the world is to slow the trend of the devastating impacts of climate change.

By the end of 2020, the COVID-19 pandemic risks doubling the number of people who face acute hunger from around 135 million to around 265 million people. The pandemic may have a more severe impact on the number of hungry than the global food crisis of 2007–2008, potentially constituting a ‘hunger pandemic’.

The report ‘Surviving and thriving in the 21st century’ from Australia’s Commission for the Human Future sets out clearly and with insight the major and inter-dependent challenges that will persist beyond the pandemic – including global warming, food insecurity, biodiversity loss, environmental degradation, resource scarcity and wealth inequality. Action is vital, but how to respond seems as elusive as ever.

Former Australian politician, Dr John Hewson, now chair of Australia’s Commission for the Human Future and a professorial fellow at the Crawford School of Public Policy at the Australian National University, warns that ‘the coronavirus pandemic should be seen as a dress rehearsal for what awaits us if we continue to ignore the laws of science, the physical world and the demands of several catastrophic threats such as climate change’.
