TADEAS: Jojo, neco vanocniho

The Earth is on a “disastrous trajectory” with “no adequate global governance” to deal with the scale of threats posed by climate tipping points, warns a major new report.
These tipping points “pose some of the gravest threats faced by humanity”, according to the authors.
They identify more than 25 tipping points across the Earth system, ranging from ice-sheet collapse to rainforest dieback.
“Five major tipping points are already at risk of being crossed due to warming right now and three more are threatened in the 2030s as the world exceeds 1.5C global warming,” the report finds.

SEEDS OF EUROPE

Summer 2023. 2 young filmmakers travelled through Europe visiting seed producers at their workplaces and experiencing first-hand how important it is to preserve this diversity in Europe. The short documentary gives a voice to these small-scale seed producers and seed savers from across Europe, with beautiful footage shot in Ireland, Luxembourg, France, Italy, Austria and the Czech Republic.

For diversity on our plates and in nature, we also need diversity in seeds. However, when we look at the selection available in supermarkets, including in the vegetable aisle, it quickly becomes clear that everything looks the same, almost all the time and all year round. Why is that? Because large corporations have power over the market. Now, however, EU seed legislation is being reformed - a chance to save seed diversity.

In a paper published in Science, we introduce GraphCast, a state-of-the-art AI model able to make medium-range weather forecasts with unprecedented accuracy. GraphCast predicts weather conditions up to 10 days in advance more accurately and much faster than the industry gold-standard weather simulation system – the High Resolution Forecast (HRES), produced by the European Centre for Medium-Range Weather Forecasts (ECMWF).

Saudi Arabia -- the world's biggest oil exporter -- took a hardline stance, saying it would "absolutely not" agree to phasing down fossil fuels, let alone phasing them out.
This came despite scientists warning Tuesday that global warming could breach the 1.5C limit within seven years.
The thorny debate over the future of fossil fuels, the largest contributor to global warming, is the key battleground at the COP28 meeting hosted by the oil-rich United Arab Emirates.

COP28 president Sultan Al Jaber has urged governments to agree on global goals to triple renewables capacity and double the rate of energy efficiency improvements by 2030.

This call from Al-Jaber is supported by the International Energy Agency (IEA) and the International Renewable Energy Agency (IRENA), and political momentum is building.

This month, a US-China joint statement on climate change backed tripling renewables to substitute coal, oil and gas power and bring about “post-peaking meaningful absolute power sector emission reduction”.

The context for these targets is a world that remains dramatically off course against global climate goals, with recent assessments pointing to warming of 2.4-2.7C above pre-industrial levels by 2100.

In its recent report on how to get back on track, the IEA said tripling renewables, doubling efficiency and slashing methane emissions 75% by 2030 would provide 80% of the emissions cuts needed for 1.5C.

TUHO: Based on current climate policies around the world, various groups estimate that we’re now on track for around 2.5°C (4.5°F) global warming by 2100.

On the one hand, that’s not yet good enough to meet the target set in the Paris agreement. On the other hand, climate policies and clean technologies deployed over just the past eight years have already erased a full degree Celsius of global warming from the future world in 2100. Governments need to do more in the coming years to bring the Paris goals within reach, but the progress made over just the past eight years has been remarkable, especially in comparison to the prior decades of futility.
