NASA satellite imagery revealed that Tropical Depression 4 appears to be losing its punch, and the National Hurricane Center expects the storm to weaken.

On July 7, 2017, at 11:30 a.m. EDT (1530 UTC), the Moderate Resolution Imaging Spectroradiometer, or MODIS, instrument aboard NASA's Terra satellite captured a visible image of Tropical Depression 4 as it continued moving through the north Central Atlantic Ocean. The image showed that the depression consisting of a possible circulation center embedded within a very small area of intermittent convection. The MODIS image does not show much organization.

"Now I know mosses have a whole secret world,” says Jean, a University of Saskatchewan biology PhD student. “It’s like discovering a mini forest in the forest.” 

Not just pretty, mosses contribute up to 30 per cent of Canada’s boreal forest total growth every year, while maintaining the organic floor necessary for evergreens to grow. 

If it’s all in the timing, then climate change may spell problems for bees. Scientists have found that global warming may cause temporal mismatches between bees and the plant species on which they depend for food.

Among the places expected to be most hard-hit by sea level rise in the coming century or two are the islands of the tropical Pacific Ocean, ranging from sparsely developed archipelagos in Micronesia to heavily populated coastal areas on the Hawaiian Islands, such as Honolulu. 

If there is anywhere for carbon dioxide to disappear in large quantities from the atmosphere, it is into the Earth’s oceans. There, huge populations of plankton can soak up carbon dioxide from surface waters and gobble it up as a part of photosynthesis, generating energy for their livelihood. When plankton die, they sink thousands of feet, taking with them the carbon that was once in the atmosphere, and stashing it in the deep ocean.

Researchers have called for health professionals and climate forecasters to work more closely together ahead of extreme weather events and gradual climate change to help prevent the spread of infections.

Climate evolution shows some regularities, which can be traced throughout long periods of earth’s history. One of them is that the global average temperature and the carbon dioxide concentration in the atmosphere usually go hand-in-hand. To put it simple: If the temperatures decline, the CO2 values also decrease and vice versa.

As Tropical Depression 4 was getting organized in the central Atlantic Ocean the Global Precipitation Measurement Mission or GPM satellite peered into the storm and measured rainfall within. The system became Tropical Depression 4 on July 6.

University of Adelaide researchers have for the first time demonstrated that the ocean acidification expected in the future will reduce fish diversity significantly, with small ‘weedy’ species dominating marine environments. 

UC Riverside researchers analyze 38 climate models and project California will get on average 12 percent more precipitation through 2100.
