Non-technical summary
We summarize some of the past year's most important findings within climate change-related research. New research has improved our understanding about the remaining options to achieve the Paris Agreement goals, through overcoming political barriers to carbon pricing, taking into account non-CO2 factors, a well-designed implementation of demand-side and nature-based solutions, resilience building of ecosystems and the recognition that climate change mitigation costs can be justified by benefits to the health of humans and nature alone. We consider new insights about what to expect if we fail to include a new dimension of fire extremes and the prospect of cascading climate tipping elements.
Technical summaryA synthesis is made of 10 topics within climate research, where there have been significant advances since January 2020. The insights are based on input from an international open call with broad disciplinary scope. Findings include: (1) the options to still keep global warming below 1.5 °C; (2) the impact of non-CO2 factors in global warming; (3) a new dimension of fire extremes forced by climate change; (4) the increasing pressure on interconnected climate tipping elements; (5) the dimensions of climate justice; (6) political challenges impeding the effectiveness of carbon pricing; (7) demand-side solutions as vehicles of climate mitigation; (8) the potentials and caveats of nature-based solutions; (9) how building resilience of marine ecosystems is possible; and (10) that the costs of climate change mitigation policies can be more than justified by the benefits to the health of humans and nature.

Introduction
Coping plays an important role in processes involved in the development of mental disorders, influencing decompensation and recovery from patients. Coping is defined as an active self-generation of cognitive and behavioural procedures, which impact directly on the symptom or reduce distress caused by it. How patients cope with delusions lack empirical evidence. Although, in the last years, delusion has been considered a multidimensional phenomenon where emotional, cognitive and action-oriented aspects were recognized, the impact of delusional dimensions on coping is still unknown.
ObjectivesTo assess coping strategies used by patients with schizophrenia and psychotic depression to deal with delusion. The relationships between coping, psychopathology and the dimensions of delusional experience will be examined.
MethodsThirty deluded schizophrenics and 30 psychotic depressed patients were investigated. Instruments to the assessment of delusion were used, as the Positive and Negative Syndrome Scale (PANSS) and the Heidelberger Delusion Profile (HDP).
Correlations between psychopathology, coping and delusion dimensions were calculated.
ResultsCoping strategies used to deal with delusion were different in the 2 groups of patients. Schizophrenic patients use more medical care, while psychotic depressed patients use more depressive coping. Significant correlations between psychopathology, coping and delusion dimensions could be shown. In contrast to depressive patients, the emotional and cognitive dimensions of delusion seem to influence coping in patients with schizophrenia.
ConclusionsCoping strategies are different depending on the diagnosis. In schizophrenia, the emotional and the cognitive dimensions seem to influence how patients cope with delusional experience.
The value of cows in reference populations for genomic selection of new functional traits

Today, almost all reference populations consist of progeny tested bulls. However, older progeny tested bulls do not have reliable estimated breeding values (EBV) for new traits. Thus, to be able to select for these new traits, it is necessary to build a reference population. We used a deterministic prediction model to test the hypothesis that the value of cows in reference populations depends on the availability of phenotypic records. To test the hypothesis, we investigated different strategies of building a reference population for a new functional trait over a 10-year period. The trait was either recorded on a large scale (30 000 cows per year) or on a small scale (2000 cows per year). For large-scale recording, we compared four scenarios where the reference population consisted of 30 sires; 30 sires and 170 test bulls; 30 sires and 2000 cows; or 30 sires, 2000 cows and 170 test bulls in the first year with measurements of the new functional trait. In addition to varying the make-up of the reference population, we also varied the heritability of the trait (h2 = 0.05 v. 0.15). The results showed that a reference population of test bulls, cows and sires results in the highest accuracy of the direct genomic values (DGV) for a new functional trait, regardless of its heritability. For small-scale recording, we compared two scenarios where the reference population consisted of the 2000 cows with phenotypic records or the 30 sires of these cows in the first year with measurements of the new functional trait. The results showed that a reference population of cows results in the highest accuracy of the DGV whether the heritability is 0.05 or 0.15, because variation is lost when phenotypic data on cows are summarized in EBV of their sires. The main conclusions from this study are: (i) the fewer phenotypic records, the larger effect of including cows in the reference population; (ii) for small-scale recording, the accuracy of the DGV will continue to increase for several years, whereas the increases in the accuracy of the DGV quickly decrease with large-scale recording; (iii) it is possible to achieve accuracies of the DGV that enable selection for new functional traits recorded on a large scale within 3 years from commencement of recording; and (iv) a higher heritability benefits a reference population of cows more than a reference population of bulls.
