In 2004, Gavin Schmidt reported decades of significant cooling over Antarctica.
The administration has cut 22 regulations for every new rule introduced, President Donald Trump announced at the White House Thursday.
Agencies and departments issued 67 deregulatory actions and imposed only three new rules in the fiscal year 2017, according to senior administration officials. The number far exceeded Trump’s goal through his executive order to cut two old rules for any new regulation proposed.
Scientific American Magazine was at one time an informative and objective publication. But in recent times, it has begun turning into a leftist rag, part of the trend toward politicizing science. Here is the latest example.
In a remarkable article published online, a professor at Ohio State University has spilled the beans on how you can be brainwashed—so as to, as he puts it, “update” your “beliefs.”
The Trump administration will reverse course from previous Obama administration policy, eliminating climate change from a list of national security threats.
The National Security Strategy to be released on Monday will emphasize the importance of balancing energy security with economic development and environmental protection, according to a source who has seen the document and shared excerpts of a late draft.
In a compromise tax reform package, Senate and House negotiators have agreed to include language to open Alaska’s coastal plain for energy exploration and production.
If passed, the bill would finally give Alaskans more control over their energy future by opening the Arctic National Wildlife Refuge (ANWR).
The Paris Agreement adopted in December 2015 during the COP21 climate conference stipulates that the increase in the global average temperature is to be kept well below 2°C above “pre-industrial levels” and that efforts are pursued to limit the temperature increase to 1.5°C above “pre-industrial levels.”
Closer inspection of the treaty text, however, reveals that the term “pre-industrial levels” is nowhere defined in this epochal UN-document, that has meanwhile been ratified by 170 Parties.
The House and Senate agreed Thursday to scrap a proposal eliminating a large tax credit the electric vehicle market and other green energy companies rely on to keep the fledgling industry afloat.
Lawmakers spared a $7,500 electric-vehicle tax credit and a wind production tax credit that Republicans nixed to balance out the hefty tax bill, according to a Bloomberg report Thursday. The Senate’s version of the bill does not include the provision.
Two new studies are out purporting to show a link between Hurricane Harvey and man-made global warming, sparking a wave of media coverage hyping the supposed climate connection.
But there are good reasons to be skeptical of both studies claiming to link a singular weather event like Hurricane Harvey to global warming.
1. Significant Decreasing Trend In Severe Weather Since 1961
Based on continuous and coherent severe weather reports from over 500 manned stations, for the first time, this study shows a significant decreasing trend in severe weather occurrence across China during the past five decades. The total number of severe weather days that have either thunderstorm, hail and/or damaging wind decrease about 50% from 1961 to 2010. It is further shown that the reduction in severe weather occurrences correlates strongly with the weakening of East Asian summer monsoon which is the primary source of moisture and dynamic forcing conducive for warm-season severe weather over China.
2. Most Frequent Climate Instability During Global Cooling/Reduced CO2 Periods
Numerical experiments using a fully coupled atmosphere-ocean general circulation model with freshwater hosing in the northern North Atlantic showed that climate becomes most unstable in intermediate glacial conditions associated with large changes in sea ice and the Atlantic Meridional Overturning Circulation. Model sensitivity experiments suggest that the prerequisite for the most frequent climate instability with the bipolar seesaw pattern during the late Pleistocene era is associated with reduced atmospheric CO2 concentration via global cooling and sea ice formation in the North Atlantic, in addition to extended Northern Hemisphere ice sheets.
3. Hurricane Activity Is ‘Subdued’ During Warm Periods (1950-2000)
The hurricane analysis conducted by Burn and Palmer (2015) determined that hurricane activity was subdued during the [warm] Medieval Climate Anomaly (MCA) (~900-1350 CE) and became more produced during the [cold] Little Ice Age (LIA) (~1450-1850 CE), followed by a period of variability occurred between ~1850 and ~1900 before entering another subdued state during the industrial period (~1950-2000 CE). In general, the results of this study corroborate these findings … [W]hile hurricane activity was greater during the LIA, it also had more frequent periods of drought compared to the MCA (Burn and Palmer 2014), suggesting that climate fluctuations were more pronounced in the LIA compared to the MCA. The changes in the diatom distribution and fluctuations in chl-a recorded in this study starting around 1350 also indicate that variations in climate have become more distinct during the LIA and from ~1850-1900.
[C]limate variability has increased following the onset of the Little Ice Age (~1450-1850 CE), however, it is difficult to distinguish the impacts of recent anthropogenic climate warming on hurricane activity from those of natural Atlantic climate regimes, such as ENSO.
4. Surface Warming Weakens Cyclone Activity
Results indicate that the midlatitude summer cyclone activity over East Asia exhibits decadal changes in the period of 1979–2013 and is significantly weakened after the early 1990s. … Moreover, there is a close linkage between the weakening of cyclonic activity after the early 1990s and the nonuniform surface warming of the Eurasian continent. Significant warming to the west of Mongolia tends to weaken the north-south temperature gradient and the atmospheric baroclinicity to its south and eventually can lead to a weakening of the mid-latitude cyclone activity over East Asia.
- More Hydroclimatic Variability During Cold Periods…Models Say Warming Causes More Instability, So The 21st Century Will Be Like The Little Ice Age, With More Instability/Megadrought
Image Source: Loisel et al., 2017
Our tree-ring-based analysis of past drought indicates that the Little Ice Age (LIA) experienced high interannual hydroclimatic variability, similar to projections for the 21st century. This is contrary to the Medieval Climate Anomaly (MCA), which had reduced variability and therefore may be misleading as an analog for 21st-century warming, notwithstanding its warm (and arid) conditions. Given past non-stationarity and particularly erratic LIA, a ‘warm LIA’ climate scenario for the coming century that combines high precipitation variability (similar to LIA conditions) with warm and dry conditions (similar to MCA conditions) represents a plausible situation that is supported by recent climate simulations. … Our comparison of tree-ring-based drought analysis and records from the tropical Pacific Ocean suggests that changing variability in El Niño Southern Oscillation (ENSO) explains much of the contrasting variances between the MCA and LIA conditions across the American Southwest. The Medieval Climate Anomaly (MCA, ~950–1400 CE) is often used as an analog for 21stcentury hydroclimate because it represents a warm (and arid) period. The MCA appears related to general surface warming in the Northern Hemisphere, prolonged La Niña conditions, and a persistent positive North Atlantic Oscillation mode. It has been referred to as a stable time interval with ‘quiet’ conditions in regards to low perturbation by external radiative forcing. In this study, we demonstrate that the Little Ice Age (LIA, ~1400–1850 CE) might be more representative of future hydroclimatic variability than the conditions during the MCA megadroughts for the American Southwest, and thus provide a useful scenario for the development of future water-resource management and drought and flood hazard mitigation strategies.

The second round of White House-brokered talks on the future of the nation’s renewable fuel program ended Wednesday with a warning from the corn ethanol camp who said no solution can be reached if it means undermining the Renewable Fuel Standard.
The meeting took place at the Eisenhower Executive Office Building next to the White House between the pro-ethanol team led by Iowa Republican Sen. Chuck Grassley’s staff and the pro-oil team led by Texas Republican Sen. Ted Cruz’s staff.
One of the nation’s top environmental groups on Wednesday sent boxes of “endangered species condoms” to six top officials at the Department of Health and Human Services.
The Center for Biological Diversity’s holiday mailing is meant to draw attention to human population growth, which the group says is hurting wildlife and ecosystems across the country.
