This newspaper comprehensively reports from foreign media A new study from an international expert group on net zero emissions led by the Department of Physics at the University of Oxford in the UK shows，Only relying on the forest、Natural bet365 bonus bets sinks such as oceans to offset the bet365 bonus bets dioxide produced by the use of fossil fuels，It is not really effective in preventing global warming。The research was recently published in the magazine "Nature"。

In scientific research on net-zero emissions 15 years ago，Scholars do not include natural bet365 bonus bets sinks when defining net anthropogenic bet365 bonus bets dioxide emissions。The role of natural bet365 bonus bets sinks in mitigating the impact of current bet365 bonus bets emissions、Continuing to reduce atmospheric bet365 bonus bets dioxide concentrations after achieving net zero emissions、Plays a vital role in stabilizing global temperatures。However，Governments and businesses are increasingly relying on natural bet365 bonus bets sinks to offset bet365 bonus bets emissions，Instead of reducing the use of fossil fuels or developing more sustainable treatment solutions。At the same time，By establishing a clear conversion relationship between fossil fuel emissions and bet365 bonus bets dioxide absorption by natural bet365 bonus bets sinks，bet365 bonus bets emissions accounting rules also encourage this practice。This results in even a country appearing to have achieved net zero emissions，May actually still be contributing to global warming。Therefore，The international expert group appeals，Governments and businesses must be clear about the extent to which they rely on natural bet365 bonus bets sinks to achieve their climate goals，And recognize the importance of geological net-zero emissions。

Geological net-zero emissions means balancing the flow of bet365 bonus bets into and out of the solid Earth，That’s one metric ton of bet365 bonus bets dioxide produced for every fossil fuel use，One metric ton of bet365 bonus bets dioxide will be geologically stored。Considering the cost and difficulty of permanent geological storage of bet365 bonus bets dioxide，Achieving geological net-zero emissions requires significant reductions in fossil fuel use。A country’s total historical bet365 bonus bets emissions affect its relationship with today’s global natural bet365 bonus bets sink needs。For example，The UK’s historical bet365 bonus bets emissions are very high but natural bet365 bonus bets sink resources are limited，The UK has been negotiating with other countries on this issue，But it is always difficult to find a solution。

Myles Allen, Professor of Physics at Oxford University mentioned，People are already hoping to use forests and oceans to make up for past bet365 bonus bets emissions，We cannot expect them to be able to offset future bet365 bonus bets emissions produced by humans。By mid-century，Any bet365 bonus bets dioxide produced by burning fossil fuels extracted from the ground should be permanently sequestered back into the ground，Achieving geological net-zero emissions。

said Glen Peters, senior researcher at the International Center for Climate and Environmental Research in Oslo, Norway，Currently，When countries announce their response to climate change, they mostly focus on bet365 bonus bets emissions and bet365 bonus bets removals。However，Natural bet365 bonus bets sinks help humans clean up about half of annual bet365 bonus bets emissions，To effectively prevent global warming，This ecosystem service must be distinguished from true removals。

Kirsten Zickfeld, Distinguished Professor of Geography at Simon Fraser University in Canada，It is generally believed，Removing bet365 bonus bets dioxide from the atmosphere to offset the burning of fossil fuels is just as effective as not burning fossil fuels in the first place，But that’s not the case。If bet365 bonus bets removal is considered part of the natural bet365 bonus bets cycle，And the bet365 bonus bets is not permanently sequestered，Then，Offsetting continued fossil fuel use through bet365 bonus bets removal will not work。Unless countries are more transparent in reporting their status and setting climate targets，Otherwise such offsets will become a tool that exacerbates climate problems，Instead of being part of a valid solution。

In the opinion of Jo House, associate professor at the School of Geographical Sciences at the University of Bristol, UK，Land is limited，Humans depend on the land for food、Acquire natural resources、Guaranteeing biological diversity, etc.。Land cannot fully offset CO2 emissions from the use of fossil fuels，Due to population growth and fires、Drought and other problems，This offsetting effect may be weakened in the future。People must protect natural bet365 bonus bets sinks，Combined with other bet365 bonus bets sink compensation mechanisms，By More Science、More reliable、A fairer way to ensure climate goals are achieved。
