    Nope. Socialism killed far more.

    Loss of sea otters accelerating the effects of climate change

    "We discovered that massive limestone reefs built by algae underpin the Aleutian Islands' kelp forest ecosystem," said Douglas Rasher, a senior research scientist at Bigelow Laboratory for Ocean Sciences and the lead author of the study. "However, these long-lived reefs are now disappearing before our eyes, and we're looking at a collapse likely on the order of decades rather than centuries."

    The coral-like reefs, built by the red alga Clathromorphum nereostratum, are being ground down by sea urchins. Sea urchins exploded in number after their predator, the Aleutian sea otter, became functionally extinct in the 1990's. Without the urchins' natural predator to keep them in check, urchins have transformed the seascape -- first by mowing down the dense kelp forests, and now by turning their attention to the coralline algae that form the reef.

    "Ocean warming and acidification are making it difficult for calcifying organisms to produce their shells, or in this case, the alga's protective skeleton," said Rasher, who led the international team of researchers that included coauthors Jim Estes from UC Santa Cruz and Bob Steneck from University of Maine. "This critical species has now become highly vulnerable to urchin grazing -- right as urchin abundance is peaking. It's a devastating combination."

    Heat stored in the Earth system: where does the energy go?

    Abstract

    Human-induced atmospheric composition changes cause a radiative imbalance at the top of the atmosphere which is driving global warming. This Earth energy imbalance (EEI) is the most critical number defining the prospects for continued global warming and climate change. Understanding the heat gain of the Earth system – and particularly how much and where the heat is distributed – is fundamental to understanding how this affects warming ocean, atmosphere and land; rising surface temperature; sea level; and loss of grounded and floating ice, which are fundamental concerns for society. This study is a Global Climate Observing System (GCOS) concerted international effort to update the Earth heat inventory and presents an updated assessment of ocean warming estimates as well as new and updated estimates of heat gain in the atmosphere, cryosphere and land over the period 1960–2018. The study obtains a consistent long-term Earth system heat gain over the period 1971–2018, with a total heat gain of 358±37 ZJ, which is equivalent to a global heating rate of 0.47±0.1 W m−2. Over the period 1971–2018 (2010–2018), the majority of heat gain is reported for the global ocean with 89 % (90 %), with 52 % for both periods in the upper 700 m depth, 28 % (30 %) for the 700–2000 m depth layer and 9 % (8 %) below 2000 m depth. Heat gain over land amounts to 6 % (5 %) over these periods, 4 % (3 %) is available for the melting of grounded and floating ice, and 1 % (2 %) is available for atmospheric warming. Our results also show that EEI is not only continuing, but also increasing: the EEI amounts to 0.87±0.12 W m−2 during 2010–2018. Stabilization of climate, the goal of the universally agreed United Nations Framework Convention on Climate Change (UNFCCC) in 1992 and the Paris Agreement in 2015, requires that EEI be reduced to approximately zero to achieve Earth's system quasi-equilibrium. The amount of CO2 in the atmosphere would need to be reduced from 410 to 353 ppm to increase heat radiation to space by 0.87 W m−2, bringing Earth back towards energy balance. This simple number, EEI, is the most fundamental metric that the scientific community and public must be aware of as the measure of how well the world is doing in the task of bringing climate change under control, and we call for an implementation of the EEI into the global stocktake based on best available science. Continued quantification and reduced uncertainties in the Earth heat inventory can be best achieved through the maintenance of the current global climate observing system, its extension into areas of gaps in the sampling, and the establishment of an international framework for concerted multidisciplinary research of the Earth heat inventory as presented in this study. This Earth heat inventory is published at the German Climate Computing Centre (DKRZ, DKRZ - Partner der Klimaforschung — DKRZ https://www.dkrz.de/, last access: 7 August 2020) under the DOI CERA - Metadata for 'GCOS_EHI_EXP_v2' https://doi.org/10.26050/WDCC/GCOS_EHI_EXP_v2 (von Schuckmann et al., 2020).

    So you believe science couldn't forecast climate and so called AGW consequences for even five years, but you promulgate they can do so for the far future, don't make such a fool of yourself please, better start seriously living up yourself what you preach, only after that honorable persons might be thinking about bothering others with their so called believes.

    And stop paying to snake oil salesmen $$$ for carbon offsets. You may as well try to buy Brooklyn Bridge.

    Not 'snake oil', religious 'Indulgences'.

    "Indulgence, a distinctive feature of the penitential system of both the Western medieval and the Roman Catholic Church that granted full or partial remission of the punishment of sin."

    Someday, we'll sit in judgement over the angels.
    Followers of the AGW religion, one day will become a greenhouse gas. Methane.
    Justice for all.

    It's like George Parker is still alive, or just nothing has changed in how easy many are to con and to become their prophet . . :eek:

    ‘‘ . . . Parker is remembered as one of the most successful con men in the history of the United States, as well as one of history's most talented hoaxers. . . . ’’

    It appears that a substantial fraction of this thread's participants think that ad hominem arguments will somehow, magically, make AGW go away. Sad. :(

    I already own the Brooklyn Bridge. Believe me, it's more trouble than it's worth, but if any of you guys think you can do something better with it, I'll let it go cheap.
