Changing world : cold data for a warming planet
The terrifying effects of a warming planet are impossible to ignore, but sometimes it's hard to pick through the facts and to understand exactly what's happening and how. This book of bright, bold infographics illuminates the realities of climate change in hard numbers, digestible data and vivid visualizations. How will rising sea levels affect us? What is the impact of meat on the planet? What industries create the most emissions? How do renewable energies compare to one another? What are the most effective things we as individuals can do to help the planet? Without sugar-coating or fear-mongering, this is a book that conveniently unpacks inconvenient truths in a way that is accessible to readers young and old.

Unsettled : what climate science tells us, what it doesn't, and why it matters
The author points out that core questions about the way the climate is responding to our influence and what the impacts will be remain largely unanswered. He provides insights and perspective free from political agendas, dispels popular myths, and unveils little-known truths. He points out that the models we use to predict the future aren't able to accurately describe the climate of the past, suggesting they are deeply flawed.

Restoring natural forests is the best way to remove atmospheric carbon
Plans to triple the area of plantations will not meet 1.5 °C climate goals. New natural forests can, argue Simon L. Lewis, Charlotte E. Wheeler and colleagues.

and because wildfires are below the grid scale of global climate models. Here we use machine learning to quantify empirical relationships between temperature (as well as the influence of temperature on aridity) and the risk of extreme daily wildfire growth (>10,000 acres) in California and find that the influence of temperature on the risk is primarily mediated through its influence on fuel moisture. We use the uncovered relationships to estimate the changes in extreme daily wildfire growth risk under anthropogenic warming by subjecting historical fires from 2003 to 2020 to differing background climatological temperatures and aridity conditions. We find that the influence of anthropogenic warming on the risk of extreme daily wildfire growth varies appreciably on a fire-by-fire and day-by-day basis, depending on whether or not climate warming pushes conditions over certain thresholds of aridity, such as 1.5 kPa of vapour-pressure deficit and 10% dead fuel moisture. So far, anthropogenic warming has enhanced the aggregate expected frequency of extreme daily wildfire growth by 25% (5–95 range of 14–36%), on average, relative to preindustrial conditions. But for some fires, there was approximately no change, and for other fires, the enhancement has been as much as 461%. When historical fires are subjected to a range of projected end-of-century conditions, the aggregate expected frequency of extreme daily wildfire growth events increases by 59% (5–95 range of 47–71%) under a low SSP1–2.6 emissions scenario compared with an increase of 172% (5–95 range of 156–188%) under a very high SSP5–8.5 emissions scenario, relative to preindustrial conditions.
Quantification of climate warming in California using machine learning shows increased daily wildfire growth risk by 25%, with an expected increase of 59% and 172% in 2100, for low- and very-high-emissions scenarios, respectively.

Realization of Paris Agreement pledges may limit warming just below 2 °C
Over the last five years prior to the Glasgow Climate Pact

, 154 Parties have submitted new or updated 2030 mitigation goals in their nationally determined contributions and 76 have put forward longer-term pledges. Quantifications of the pledges before the 2021 United Nations Climate Change Conference (COP26) suggested a less than 50 per cent chance of keeping warming below 2 degrees Celsius

. Here we show that warming can be kept just below 2 degrees Celsius if all conditional and unconditional pledges are implemented in full and on time. Peak warming could be limited to 1.9–2.0 degrees Celsius (5%–95% range 1.4–2.8 °C) in the full implementation case—building on a probabilistic characterization of Earth system uncertainties in line with the Working Group I contribution to the Sixth Assessment Report

of the Intergovernmental Panel on Climate Change (IPCC). We retrospectively project twenty-first-century warming to show how the aggregate level of ambition changed from 2015 to 2021. Our results rely on the extrapolation of time-limited targets beyond 2030 or 2050, characteristics of the IPCC 1.5 °C Special Report (SR1.5) scenario database

and the full implementation of pledges. More pessimistic assumptions on these factors would lead to higher temperature projections. A second, independent emissions modelling framework projected peak warming of 1.8 degrees Celsius, supporting the finding that realized pledges could limit warming to just below 2 degrees Celsius. Limiting warming not only to ‘just below’ but to ‘well below’ 2 degrees Celsius or 1.5 degrees Celsius urgently requires policies and actions to bring about steep emission reductions this decade, aligned with mid-century global net-zero CO

emissions.
If all new and updated national climate change mitigation pledges stemming from the Paris Agreement are implemented in full and on time, then 21st-century warming could be limited to just below 2 degrees Celsius.

Three years to safeguard our climate
According to an April report1 (prepared by Carbon Tracker in London, the Climate Action Tracker consortium, the Potsdam Institute for Climate Impact Research in Germany and Yale University in New Haven, Connecticut), should emissions continue to rise beyond 2020, or even remain level, the temperature goals set in Paris become almost unattainable. The UN Sustainable Development Goals that were agreed in 2015 would also be at grave risk. That's why we launched Mission 2020 - a collaborative campaign to raise ambition and action across key sectors to bend the greenhouse-gas emissions curve downwards by 2020 (www.mission2020.global).

Global warming and recurrent mass bleaching of corals
During 2015–2016, record temperatures triggered a pan-tropical episode of coral bleaching, the third global-scale event since mass bleaching was first documented in the 1980s. Here we examine how and why the severity of recurrent major bleaching events has varied at multiple scales, using aerial and underwater surveys of Australian reefs combined with satellite-derived sea surface temperatures. The distinctive geographic footprints of recurrent bleaching on the Great Barrier Reef in 1998, 2002 and 2016 were determined by the spatial pattern of sea temperatures in each year. Water quality and fishing pressure had minimal effect on the unprecedented bleaching in 2016, suggesting that local protection of reefs affords little or no resistance to extreme heat. Similarly, past exposure to bleaching in 1998 and 2002 did not lessen the severity of bleaching in 2016. Consequently, immediate global action to curb future warming is essential to secure a future for coral reefs.
Aerial and underwater survey data combined with satellite-derived measurements of sea surface temperature over the past two decades show that multiple mass-bleaching events have expanded to encompass virtually all of the Great Barrier Reef.
Barrier reef bleaching
The Great Barrier Reef is the world's largest reef system, but is being increasingly affected by climate change. Terry Hughes and colleagues examine changes in the geographic footprint of mass bleaching events on the Great Barrier Reef over the last two decades, using aerial and underwater survey data combined with satellite-derived measurements of sea surface temperature. They show that the cumulative footprint of multiple bleaching events has expanded to encompass virtually all of the Great Barrier Reef, reducing the number and size of potential refuges. The 2016 bleaching event proved the most severe, affecting 91% of individual reefs. The authors call for immediate global action to reduce the magnitude of climate warming in order to secure a future for coral reefs.

Emissions: world has four times the work or one-third of the time
[...]the international community now agrees that it must ensure a lower global temperature rise than it decided ten years ago, because climate risks are better understood. From 2010 to 2014, the gap reports projected the likely difference in 2020 between the expected result of countries' pledges and the pathways towards 2 °C. The 2010 report documented a shortfall of 14%. Since 2015, the reports have forecast the expected shortfall in 2030 between the countries' pledges and progress towards both 1.5 °C (current shortfall of 55%) and 2°C (current shortfall of 25%; see 'More and faster'). [...]the required cuts from 2020 are now more than 7% per year on average for 1.5 °C (close to 3% for 2 °C). (The United States has begun the process of withdrawing from the Paris agreement, and will leave in November.) Russia and Turkey have set themselves unambitious targets that they can meet without new policies. Since 2015, estimated global emissions in 2030 have decreased by only 3%.
