Carbon criminals, climate crimes
Carbon Criminals, Climate Crimes analyzes the looming threats posed by climate change from a criminological perspective. It advances the field of green criminology through a examination of the criminal nature of catastrophic environmental harms resulting from the release of greenhouse gases. The book describes and explains what corporations in the fossil fuel industry, the U.S. government, and the international political community did, or failed to do, in relation to global warming. Carbon Criminals, Climate Crimes integrates research and theory from a wide variety of disciplines, to analyze four specific state-corporate climate crimes: continued extraction of fossil fuels and rising carbon emissions; political omission (failure) related to the mitigation of these emissions; socially organized climate change denial; and climate crimes of empire, which include militaristic forms of adaptation to climate disruption. The final chapter reviews policies that could mitigate greenhouse gas emissions, adapt to a warming world, and achieve climate justice.

Reconciling controversies about the ‘global warming hiatus’
Between about 1998 and 2012, a time that coincided with political negotiations for preventing climate change, the surface of Earth seemed hardly to warm. This phenomenon, often termed the ‘global warming hiatus’, caused doubt in the public mind about how well anthropogenic climate change and natural variability are understood. Here we show that apparently contradictory conclusions stem from different definitions of ‘hiatus’ and from different datasets. A combination of changes in forcing, uptake of heat by the oceans, natural variability and incomplete observational coverage reconciles models and data. Combined with stronger recent warming trends in newer datasets, we are now more confident than ever that human influence is dominant in long-term warming.
Apparently contradictory conclusions regarding the ‘global warming hiatus’ are reconciled, strengthening the current scientific understanding that long-term global warming is extremely likely to be of anthropogenic origin.
Analysis of a global warming hiatus
After a spike in global-mean temperature associated with the 1998 El Niño, the climate system experienced several years of reduced warming, and perhaps even slight cooling. This period, variously termed the 'hiatus', 'pause' or 'slowdown', should have come as no surprise given our understanding of El Niño and natural climate variability. However, soon after the recognition of the reduced warming, it appeared that models and observations were diverging, raising the question of whether the models were missing important processes. Although global warming has since recommenced, the hiatus sparked an enormous research effort. Iselin Medhaug
et al
. synthesize the literature and reassess the model and observational evidence. Their assessment reconciles the apparent contradictions between models and data and obviates the need to revise our understanding of the underlying physics of climate systems. The hiatus was an episode of natural variability after all.

Signature of ocean warming in global fisheries catch
The mean temperature of the catch, an index designed to characterize the effect of climate change on global fisheries catch, increased at a rate of 0.19 degrees Celsius per decade between 1970 and 2006, showing that ocean warming has already affected global fisheries.
Response of fish populations to warming
In a warming climate, we would expect the rise of warm-water marine species at the expense of those adapted to cooler waters. That characteristic pattern has now been detected in a study of catch composition in 52 large marine ecosystems between 1970 and 2006, a sample that includes most of the world's major fisheries. The authors develop an index, the MTC (mean temperature of the catch), calculated from the average inferred temperature preference of exploited species weighted by their annual catch. Over these years, global temperature preference increased at a rate of about 0.2 °C every decade, and the effects were even more pronounced in non-tropical areas. Taken together, these findings highlight the need to develop adaptation plans to minimize the impacts of climate change on the economy and food security of coastal communities.
Marine fishes and invertebrates respond to ocean warming through distribution shifts, generally to higher latitudes and deeper waters. Consequently, fisheries should be affected by ‘tropicalization’ of catch

(increasing dominance of warm-water species). However, a signature of such climate-change effects on global fisheries catch has so far not been detected. Here we report such an index, the mean temperature of the catch (MTC), that is calculated from the average inferred temperature preference of exploited species weighted by their annual catch. Our results show that, after accounting for the effects of fishing and large-scale oceanographic variability, global MTC increased at a rate of 0.19 degrees Celsius per decade between 1970 and 2006, and non-tropical MTC increased at a rate of 0.23 degrees Celsius per decade. In tropical areas, MTC increased initially because of the reduction in the proportion of subtropical species catches, but subsequently stabilized as scope for further tropicalization of communities became limited. Changes in MTC in 52 large marine ecosystems, covering the majority of the world’s coastal and shelf areas, are significantly and positively related to regional changes in sea surface temperature

Estimating and tracking the remaining carbon budget for stringent climate targets
Research reported during the past decade has shown that global warming is roughly proportional to the total amount of carbon dioxide released into the atmosphere. This makes it possible to estimate the remaining carbon budget: the total amount of anthropogenic carbon dioxide that can still be emitted into the atmosphere while holding the global average temperature increase to the limit set by the Paris Agreement. However, a wide range of estimates for the remaining carbon budget has been reported, reducing the effectiveness of the remaining carbon budget as a means of setting emission reduction targets that are consistent with the Paris Agreement. Here we present a framework that enables us to track estimates of the remaining carbon budget and to understand how these estimates can improve over time as scientific knowledge advances. We propose that application of this framework may help to reconcile differences between estimates of the remaining carbon budget and may provide a basis for reducing uncertainty in the range of future estimates.
A method of tracking changes in estimates of the remaining carbon budget over time should help to reconcile differences between these estimates and clarify their usefulness for setting emission reduction targets.

Response of the East Antarctic Ice Sheet to Past and Future Climate Change
The East Antarctic Ice Sheet (EAIS) contains the vast majority of Earth’s glacier ice (~52 metres sea-level equivalent), but is often viewed as less vulnerable to global warming than the West Antarctic or Greenland ice sheets. However, some regions of the EAIS have lost mass over recent decades, prompting the need to re-evaluate its sensitivity to climate change. Here we review the EAIS’s response to past warm periods, synthesise current observations of change, and evaluate future projections. Some marine-based catchments that underwent significant mass loss during past warm periods are currently losing mass, but most projections indicate increased accumulation across the EAIS over the 21st Century, keeping the ice sheet broadly in balance. Beyond 2100, high emissions scenarios generate increased ice discharge and potentially several metres of sea-level rise within just a few centuries, but substantial mass loss could be averted if the Paris Agreement to limit warming below 2°C is satisfied.
