Scientists Lay It Out - Over 100 Misleading Statements And Lies In DOE Climate "Study" Written By Hand-Picked Hacks

2.1 CO2 as a contributor to global greening

FALSE

While plant models predict increased photosynthesis in response to rising CO2, Haverd et al. (2020) reported a CO2 fertilisation rate much larger than model predictions. That is, CO2 fertilisation had driven an increase in observed global photosynthesis by 30% since 1900, versus 17% predicted by plant models. If true it would indicate that global models of the socioeconomic impacts of rising CO2 have understated the benefits to crops and agriculture.

The paper by Haverd et al. focuses on natural ecosystems, not crops. So whilst the findings that CO2 fertilisation effects on global greening makes a larger share relative to other factors, the results are not directly transferable to the socio-economic impacts of rising CO2 on agriculture. Rising CO2 contributes to higher radiative forcing which increases global mean temperature and accelerates the global water cycle, causing increases in the severity and frequency of extreme weather events (e.g. droughts, heat-stress and wildfires), particularly threatening crop yields and production.

2.1 CO2 as a contributor to global greening

FALSE

Deryng et al. (2016) assumed that climate change would “exacerbate water scarcity”. Yet while models do predict that drylands will expand under climate warming, current data show the opposite: greening is happening even in arid areas.

Dr Delphine Deryng, lead author, IPCC AR6 WG2

Greening and water scarcity are processes related to different carbon and water cycles, respectively. They cannot be directly compared. Deryng et al. (2016) didn't assume but reported findings from peer-reviewed scientific studies on water scarcity trends. Deryng et al (2016) specifically stated: "Research indicates unabated climate change will exacerbate water scarcity around the world. This is thought to threaten agricultural productivity and food security, especially in arid regions, where agriculture relies heavily on irrigation and consumes the majority of diverted freshwater."

The author list is incorrect on this citation. It should be Xin Chen, Tiexi Chen, Bin He, Shuci Liu, Shengjie Zhou and Tingting Shi. It falsely associates the paper with well-known authors and demonstrates lack of attention to detail.

Arctic sea ice extent has declined by about 5% since 1980

Anonymous

September sea ice (1979-88 average compared to 2015-24 average) is 34% lower today according to OSISAF [Ocean and Sea Ice Satellite Application Facility] observations and 35% lower according to NSIDC [National Snow and Ice Data Center]. For the annual mean sea ice extent, the percentage reduction is 14% according to NSIDC and OSISAF. The number is higher in summer because that is when there is the most sea ice loss and the seasonal minimum, so the least amount to start with. In addition, the evidence given to support this statement links to a figure showing sea ice decline in Antarctica in July.
