Wildfires

Image
Levels of carbon dioxide (CO2) in the atmosphere are accelerating , even though emissions from fossil fuel burning have remained virtually the same over the past few years. One of the reason behind this is accelerating emissions from wildfires as temperatures are rising. Wildfires in Nevada caused CO2 to reach levels as high as 742 ppm on July 12, 2017 (green circle image on the right). Global warming is greatly increasing the chance for what was previously seen as an extreme weather event to occur, such as a combination of droughts and storms. Heat waves and droughts can cause much vegetation to be in a bad condition, while high temperatures can come with strong winds, storms and lightning. Wildfires cause a range of emissions, including CO2, soot, methane and carbon monoxide (CO). In Nevada, CO levels were as high as 30.43 ppm (green circle image right). Above satellite image below shows the smoke plumes and the charred area. The google maps image below further shows where the fires ...

Rain Over Arctic Ocean

Image
It's raining over the Arctic Ocean and the rain is devastating the sea ice. What are the conditions that led to this? As has been known for a long time, energy is added to Earth due to emissions by people and this translates into a warmer troposphere with more water vapor, warmer oceans and stronger winds. Warming is hitting the Arctic particularly hard, due to numerous feedbacks , as illustrated by the sea surface temperature anomalies image on the right. On July 6, 2017, cyclonic winds lined up to create a 'perfect storm'. As a result, an Atmospheric River of moisture was driven through Bering Strait into the Arctic Ocean, as shown on the images below. On July 6, 2017, 1500 UTC, winds in Bering Strait were as high as 58 km/h (36 mph) at surface level (green circle on above image left), and as high as 82 km/h (51 mph) at 850 mb (green circle on above image right). On July 6, 2017, surface temperatures of the air in Bering Strait were as high as 8.1°C (46.5°F) (green circle...

High Waves Set To Batter Arctic Ocean

Image
High temperatures hit Pakistan end May 2017. The image below shows readings as high as 51.1°C or 123.9°F on May 27, 2017 (at green circle). As the image below shows, sea temperature was as high as 32.6°C or 90.6°F on May 28, 2017 (at the green circle), 1.8°C or 3.2°F warmer than 1981-2011. High temperatures over land and at the sea surface reflect an atmosphere that contains huge amounts of energy. On May 28, 2017, the Convective Available Potential Energy ( CAPE ) reached levels as high as 7448 J/kg at the location in the United States marked by the green circle. Storms hit a large part of the United States, with  baseball-sized hail reported  on May 27, 2017. Here's a link to a reported 56 °C (132 °F) temperature recorded in Iran and here's a link to an article describing a May 28, 2017, reading in Turbat, Pakistan, initially reported by the Pakistan Meteorological Department as 53.5°C (128.3°F) and later upgraded to 54.0°C (129.2°F.) How could it be possibl...

Arctic Warming - Update May 2017

Image
The image below illustrates how much and how fast oceans are warming on the Northern Hemisphere. Trend points at 1.5°C warmer NH oceans in 2025. Shaded area covers seasonal fluctuations and natural variability. As ocean warming continues, prospects for the sea ice in the Arctic are grim. Warmer water is melting the sea ice from below. The image on the right shows ever less sea ice volume in the Arctic, reflecting huge thinning of the sea ice over the years. As the sea ice gets thinner, it becomes ever more prone to break up in pieces that will melt quicker (as more surface area becomes exposed to heat from the atmosphere and heat from the water). [ images from:  Arctic Sea Ice May 2017 ] Moreover, with more open water, stronger waves and winds can develop, increasing the chances that sea ice will melt and get pushed out of the Arctic Ocean. El Niño looks set to strike again this year and the Arctic looks set to be hit much stronger than the rest of the world, as illustrated b...
